However, in reality, warming up the engine slightly before draining is essential. This is because warm oil has lower viscosity, allowing it to flow out of the engine smoothly and carry along trapped contaminants.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">The appropriate method is to start the engine and let it idle for about 3\u20135 minutes until the temperature gauge begins to move. After that, turn off the engine and wait for approximately 1\u20132 minutes to allow system pressure to decrease, ensuring the oil is not too hot to scald your skin. Furthermore, the vehicle must be parked on a level surface only. If the ground is sloped, old engine oil will remain trapped inside the system and fail to drain completely.<\/p>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" style=\"font-size:26px\"><span class=\"ez-toc-section\" id=\"2_Opening_the_Drain_Plug_and_Catching_the_Old_Oil\"><\/span><strong>2. Opening the Drain Plug and Catching the Old Oil<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">This stage is considered the point that requires the utmost caution. If a mistake occurs, it could strip the plug or damage the threads, leading to major repair issues later on.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">First, locate the drain plug underneath the engine oil pan. Position the drain pan directly underneath and allow extra room for the oil to splash when the initial pressure is released. Always select a wrench size that perfectly fits the plug; never use a loose wrench as it will instantly strip the bolt. Next, gently loosen the plug counterclockwise. Once the plug begins to loosen, switch to turning it by hand, and pull the plug away quickly when it is about to come off to avoid letting the warm oil pour onto your hand.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">The old oil will take approximately 5\u201310 minutes to drain completely. While waiting, you should observe the characteristics of the oil. If you notice that it is pitch black, contains metallic debris, or carries a strong burnt odor, it may be a sign of engine problems that require inspection. Once the oil slows down to tiny drops, use a clean rag to wipe the drain hole and threads clean before moving to the next step.<\/p>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" style=\"font-size:26px\"><span class=\"ez-toc-section\" id=\"3_Replacing_the_Oil_Filter_and_Drain_Plug_Washer\"><\/span><strong>3. Replacing the Oil Filter and Drain Plug Washer<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Many people choose to change only the engine oil without replacing the filter, which is a mistake that allows dirt from the old filter to remain in the system. Therefore, every time you change the engine oil, you should replace both the filter and the plug washer at the same time.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">To remove the old filter, you can spin it off by hand if it is not too tight. However, if the filter is stuck, use an oil filter wrench to assist. Once removed, a small amount of oil remaining inside the filter will pour out, which is completely normal. Before installing the new filter, apply a thin coat of new engine oil around the rubber seal of the filter. This small step is crucial because it helps the seal seat tightly against the engine, prevents oil leaks, and makes future removal much easier. When placing the new filter into position, spin it by hand until it feels snug. You do not need to use tools to tighten it further, as excessive force can deform the seal and cause leaks.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">For the drain plug washer, never reuse the old one under any circumstances. Old washers have been compressed and deformed, and reusing them is a leading cause of oil leaks. After installing a new washer and reinstalling the plug, use a moderate amount of force\u2014just enough to be secure without over-tightening. Overtightening can damage the threads, and an over-tightened plug might break or loosen during vehicle usage.<\/p>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" style=\"font-size:26px\"><span class=\"ez-toc-section\" id=\"4_Adding_New_Engine_Oil_to_the_Specified_Volume\"><\/span><strong>4. Adding New Engine Oil to the Specified Volume<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Pouring in new engine oil seems like an easy task, but in reality, it requires a fair amount of precision because the volume added directly impacts the engine&#8217;s performance efficiency.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Before filling, you must check the car owner&#8217;s manual to see how many liters of oil the engine requires. Generally, passenger cars use about 3.5\u20135 liters depending on the engine size. Open the oil filler cap on top of the engine and use a funnel to prevent spills. Pour in about 80% of the specified volume first, then wait for 1\u20132 minutes to allow the oil to settle into the oil pan.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">The next critical step is using the dipstick to check the level. Pull the dipstick out, wipe it clean, reinsert it fully, and pull it out again to read the oil level at the tip. The proper level must be between the Min and Max marks, close to the top line but not exceeding it. If it has not reached the required level, add a little more oil at a time and recheck until the desired level is achieved.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Once the oil level is correct, secure the filler cap tightly. Start the engine and let it run for 1\u20132 minutes to allow the oil to circulate throughout the system. Finally, turn off the engine and wait 5 minutes for the oil to settle back down into the pan, then use the dipstick to inspect the level one last time while checking for leaks around the drain plug and filter. If everything is correct, your engine oil change is complete.<\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"1000\" height=\"650\" data-src=\"https:\/\/kcharoenyangyont.com\/wp-content\/uploads\/2026\/02\/02-\u0e27\u0e34\u0e18\u0e35\u0e40\u0e1b\u0e25\u0e35\u0e48\u0e22\u0e19\u0e19\u0e49\u0e33\u0e21\u0e31\u0e19\u0e40\u0e04\u0e23\u0e37\u0e48\u0e2d\u0e07_3.webp\" alt=\"\u0e27\u0e34\u0e18\u0e35\u0e40\u0e1b\u0e25\u0e35\u0e48\u0e22\u0e19\u0e19\u0e49\u0e33\u0e21\u0e31\u0e19\u0e40\u0e04\u0e23\u0e37\u0e48\u0e2d\u0e07\" class=\"wp-image-11254 lazyload\" data-srcset=\"https:\/\/kcharoenyangyont.com\/wp-content\/uploads\/2026\/02\/02-\u0e27\u0e34\u0e18\u0e35\u0e40\u0e1b\u0e25\u0e35\u0e48\u0e22\u0e19\u0e19\u0e49\u0e33\u0e21\u0e31\u0e19\u0e40\u0e04\u0e23\u0e37\u0e48\u0e2d\u0e07_3.webp 1000w, https:\/\/kcharoenyangyont.com\/wp-content\/uploads\/2026\/02\/02-\u0e27\u0e34\u0e18\u0e35\u0e40\u0e1b\u0e25\u0e35\u0e48\u0e22\u0e19\u0e19\u0e49\u0e33\u0e21\u0e31\u0e19\u0e40\u0e04\u0e23\u0e37\u0e48\u0e2d\u0e07_3-300x195.webp 300w, https:\/\/kcharoenyangyont.com\/wp-content\/uploads\/2026\/02\/02-\u0e27\u0e34\u0e18\u0e35\u0e40\u0e1b\u0e25\u0e35\u0e48\u0e22\u0e19\u0e19\u0e49\u0e33\u0e21\u0e31\u0e19\u0e40\u0e04\u0e23\u0e37\u0e48\u0e2d\u0e07_3-768x499.webp 768w, https:\/\/kcharoenyangyont.com\/wp-content\/uploads\/2026\/02\/02-\u0e27\u0e34\u0e18\u0e35\u0e40\u0e1b\u0e25\u0e35\u0e48\u0e22\u0e19\u0e19\u0e49\u0e33\u0e21\u0e31\u0e19\u0e40\u0e04\u0e23\u0e37\u0e48\u0e2d\u0e07_3-600x390.webp 600w\" data-sizes=\"(max-width: 1000px) 100vw, 1000px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1000px; --smush-placeholder-aspect-ratio: 1000\/650;\" \/><\/figure>\n<\/div>\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\"><span class=\"ez-toc-section\" id=\"Common_Mistakes_When_Changing_Engine_Oil_Yourself\"><\/span><strong>Common Mistakes When Changing Engine Oil Yourself<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Beginners who start doing this themselves often face similar mistakes. Some of these look like minor issues, yet they carry a massive long-term impact on the engine. The most common mistake involves the volume of oil added. Overfilling engine oil increases system pressure, causing the crankshaft to strike the oil and create air bubbles. Consequently, this reduces lubrication efficiency and can damage seals and gaskets. On the other hand, underfilling leads to insufficient lubrication, causing components to wear out rapidly and overheat abnormally.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Another mistake that many people overlook is neglecting to check for leaks after assembly is complete. Some individuals drive away immediately after filling the oil, without inspecting whether there is any oil seeping around the drain plug or the filter area. When they check again later, they might discover that the oil has leaked to a low level, affecting the lubrication system without the car owner&#8217;s knowledge.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Additionally, reusing components that have already been used\u2014such as old drain plug washers, old oil filters, or even old engine oil that has been stored for too long\u2014can trigger subsequent problems.

Our professional mechanic team thoroughly checks for leaks across every point of the lubrication system.<\/p>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\"><span class=\"ez-toc-section\" id=\"When_Should_You_Change_Engine_Oil_Earlier_Than_Scheduled\"><\/span><strong>When Should You Change Engine Oil Earlier Than Scheduled?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Although the car owner&#8217;s manual clearly defines engine oil change intervals\u2014such as every 5,000\u201310,000 kilometers or every 6 months\u2014in real-world usage, multiple factors can cause engine oil to deteriorate faster than expected. Relying solely on the scheduled intervals in the manual may not be enough. Instead, you must also learn to &#8220;read the signs&#8221; from your vehicle.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Warning signs indicating that you should change your engine oil immediately, without waiting for the scheduled interval, include:<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">The engine oil drawn from the dipstick appears abnormally pitch black and thick or sludgy.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">The engine runs unevenly or makes louder noises than usual during acceleration.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">The fuel consumption rate increases without any other apparent cause.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">The engine oil warning light illuminates on the dashboard status display.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">You consistently drive in heavy traffic conditions or operate the vehicle in dusty areas.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Additionally, for cars that are left parked for a long time without being started, the engine oil can also deteriorate in quality. This happens due to sediment accumulation and oxidation with the air. Therefore, if you detect any of these signs, <a href=\"https:\/\/kcharoenyangyont.com\/en\/contact-us\" target=\"_blank\" rel=\"noreferrer noopener\">scheduling an inspection and engine oil change service<\/a> will help maintain your engine in prime condition for the long term.<\/p>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\"><span class=\"ez-toc-section\" id=\"Guidelines_for_Choosing_the_Right_Engine_Oil_for_Your_Cars_Usage_Profile\"><\/span><strong>Guidelines for Choosing the Right Engine Oil for Your Car&#8217;s Usage Profile<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Choosing the right engine oil is not just about picking a familiar brand or selecting the most expensive option. Instead, it requires evaluating compatibility with your engine&#8217;s technical specifications and your actual driving habits.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">The first and most critical factor is <strong>&#8220;viscosity grade,&#8221;<\/strong> which is displayed as numbers such as 0W-20, 5W-30, or 10W-40. The front number followed by the letter &#8216;W&#8217; (Winter) indicates low-temperature viscosity, whereas the rear number signifies viscosity at operating temperatures. Modern vehicles with narrow clearance between engine parts typically require low-viscosity oil, such as 0W-20. On the other hand, older models or larger engines might demand higher viscosity. Therefore, you must always refer to your car owner&#8217;s manual as the primary reference.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">The next factor is the <strong>&#8220;type of engine oil,&#8221;<\/strong> which is divided into three primary categories:<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\"><strong>Mineral Oil:<\/strong> Budget-friendly but requires frequent replacement intervals.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\"><strong>Semi-Synthetic Oil:<\/strong> Offers moderate pricing and intermediate performance efficiency.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\"><strong>Fully Synthetic Oil:<\/strong> Provides maximum protection and an extended lifespan, making it ideal for high-performance vehicles and heavy-usage conditions.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Finally, consider engine oil standards, such as API (American Petroleum Institute) or ACEA (European Automobile Manufacturers Association), which indicate quality levels.

Instead, it depends on paying close attention to minor details\u2014such as selecting the correct viscosity, replacing used components every time, tightening the plug with moderate force, and thoroughly checking for leaks after assembly. If missed, these critical points can significantly impact your engine in the long run.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">For beginners who are still unsure of their skills, or car owners who prefer not to waste time and risk making mistakes, choosing an engine oil change service from the experts at <strong>K.
