Owner reviews for engine oil

Since my car has 120k km its high time to replace it.

Engine noise is a little, well noisy, mine is less rumbly/vibrationy after I changed my oil and used Amsoil Hybrid oil. I can’t generally feel anything when the engine kicks on now, before I could definitely feel it every time it kicked on.

Both are good, the high mileage and the restore and protect. I personally run Mobil 1 high mileage full synthetic with a wix filter and it has been great for me.

04 Silverado, 186k been using Mobile 1 full synthetic for the last 10+ years. Runs great!

My 02 Avalanche has has mobile 1 full synthetic it's entire life, and has 750k miles on the original engine. Never been opened or rebuilt. Piston slaps like a diesel on start up, but still running great.

Just got the oil lab report back from the sample taken during the oil change I did at 15K miles. The previous oil change at 10K was performed by the dealership. So that means that whatever the Toyota dealership put in there at 10K, was not OEM Toyota oil.

I have a 2023 Civic Si.

I did every oil change at around 8k miles which is when my maintenance minder popped up, even though the dealer recommended every 5k. No issues ever, now at 46k miles.

I only run Valvoline VR-1 40-wt in my air-cooled VWs

I used so many brands

- Motul : okay

Oil leak. Thats my G20, had to fill like 3 times oil myself during 30 000 km. Went to service and apparently they found two separate oil leaks
