Engine oil Mobil or LIQUI MOLY

I use Mobil 1 because it's the only oil that prevents VVt noise in my NB Miata

I've only used Mobil 1 5w-30 Full synthetic. I think it's the only oil I would ever use. This Mobil 1 oil has simply been the one that I used from the get go, mainly due to recommendations, and it does what it needs to do. I feel confident using the product.

The Toyota mechanic who has a YouTube channel (Car Care Nut) has previously said that Toyota OEM oil is Mobil 1 (with a few exceptions for collaboration cars).

I always use liqui-moly leichtlauf 5w40.

Mobil1 15w-50 (red label) was always good to me, and readily available at wally world. Never had lifter tick in my S50US, on track or otherwise, and it went to 298k before the head gasket gave up. Absolutely could have resealed the engine and ran it another 100k+ (swapped an S54 instead).

I use M1 Extended HM with an stp premium filter. Go about 10-13k between changes.

I mostly use the 0W-40 full synthetic Mobil 1 "European" or w/e they call it. I change my oil every 5K miles, including filter (Mann).

Liqui-Moly Molygen 5w40 every 3k-ish miles for me. I like Castrol, just prefer the LM. The quality is supposed to be fantastic.

I personally use full synthetic Mobile 1 usually.

Liqui Moly has some green stuff I put in my euro cars. It's pretty cool for finding leaks.
