Owner reviews for engine oil

liqui moly 5-40 exclusively

I use Valvoline VR1 in my street car and whatever full synthetic that is on sale for my Taurus and Titan.

Molygen entirely stopped my tensioner rattle, like, didn’t reduce it, took it from 1-2 sec on startup to never rattling again

Have an 07 Silverado bought new first oil change switched over to Mobil one used that until one of the hurricanes hit Louisiana and started having a problem getting it so switched over to Pennzoil full synthetic. Truck has 368000 on it and seems to be still going strong so I’d say it’s your choice.

I use Pennzoil Platinum. Is it the best? Who knows, but I’ve been using it for years on several vehicles and never had an issue.

Also been using Mannol. Do 6k oil changes though. Made chain noise on start up. Swapped back to mannol noise gone.

I've used Mannol for a few years, it's dirt cheap here in the UK and I've never had any issues with it.

Using Mannol since years in Mercedes Diesel and gas engines , also in a BMW Boxer.

Motul Xclean. I've read on this that Motul Xcess on FA20 makes more carbon buildup on Piston

BTW, Mobil runs hotter in my car.
