Mechanic Tyler Wesley Explains the Multi-Step Japanese Oil Change Technique Viral on Social Media
Mechanic Tyler Wesley revealed the details of a Japanese-style oil change technique that has gained popularity on social media. The process involves adding a quart of fresh oil to a hot engine before draining the old oil, followed by a full oil change and a second full oil change after a 15- to 20-minute drive.

Tyler Wesley noted that while the technique is used on some four-cylinder engines that have reached 600,000 miles, it is not a standard maintenance practice endorsed by Japanese automakers like Toyota. Toyota specifically warns against filling the dipstick above the upper mark, as excess oil can adversely affect the engine. While the process is more involved than a standard oil change, it is based on the idea that fresh oil can help loosen contaminants. However, Tyler Wesley admitted the routine seems somewhat ridiculous because it involves sacrificing an entire fresh batch of oil after only a short drive. Experts also caution that while warming an engine before an oil change is a common practice, the Japanese method requires more steps than the standard routine.
