Motul 109471 8100 X-Clean EFE 5W30 Synthetic Motor Oil 5 Liter

Best engine oil I've ever used for my Subaru !

Perfect for 2015 sti since everyone been recommending this oil. So far it very clean and good. Will be buying again once oil change time!

Seems to work just fine on my Mitsubishi eclipse

Honestly expected nothing out of this oil since the Kia / Hyundai GDI engines are known to burn at some point due to being extra hot, but I've gone 1k miles extra and the oil does not smell burnt / cooked (yes that's a thing) or look as dark as it used to be at 3k miles. I will try the X-clean+ formula to see if I can eek more milage out of my oil but even going just an extra 1k miles is worth it.Honestly stop reading the reviews and try it for yourself. If you're that paranoid just check your oil every fill up and give it a sniff. This stuff is legit.

I have been using this Motul oil in my 2015 WRX for years now and have multiple Blackstone UOA reports showing consistent good results. I do not see a reason to change with good results. I use the Subaru black filter and a magnetic drain plug bolt. Oiling system is 100% stock on my car. I usually change the oil around 5K or closer to 6K. I never go over 6K on a oil and filter change.

This engine oil is a MUST have for your 2015-2021 WRX. Superior engine protection and performance. Excellent gas mileage is an added bonus. Likely is excellent for the 2022+ as well.

Packaging is nice. Easy to pour, has graduations which is helpful

Amazing!!! My First time using this brand of oil for my Volkswagon Jetta. All I can say is, Wow. You can truly feel the difference. Smoother drive, and my engine sounds happier than ever!! I cannot recommend this product enough!! I will only be using this brand going further. Love it
