Owner reviews for engine oil

Motul is a good oil but i stuck with the OEM stuff when i replaced my clutch

Using high mileage oil (additives to make gaskets swell just a tad bit), used to burn almost a quart between 5k miles but now it's maybe half a quart.

I recently switched from the stock Royal Enfield engine oil to Motul 10W40 fully synthetic. The bike feels noticeably smoother and cleaner.

I have a 2016 Corolla and just had the oil changed at dealership at 188000 km. Worked out for me.

I also use liquimoly 4200 top tech in my 2022 rs3

I like using Amsoil because its very good at withstanding heat.

During all my oil changes, I\u2019ve taken a sample and sent off to Blackstone for analysis.\n\nEven after 12k miles, there\u2019s still enough TBN left that I could have continued using it out to 15k miles.\n\nDissolved metals and other elements were still within universal engine norms so it wasn\u2019t like the sample was abnormally contaminated.

20-50 Mobil 1 in the motor, 75-90 gear oil the transmission and the primary. I’ve done this on my 03,2017,2019,2020 and my 2024

AmsOil 10w30 for turbo engines... haven't had any issues yet. Still consumes it though.

BMW switched from Castrol to Penzoil years ago...but both cause oil starvation in The S65 motor
