Engine oil Mobil or OEM Toyota

I use the Mobil 1 just like the sticker Porsche put on your car…

I've tried various combinations that include the mix of m1 5-40 with 5-50 but have now for many years kept it simpler w/ Mobil 1 5-50 every five thousand miles. It purrs as one would expect from a 195,000 mile 996 Turbo.

My Saab (2003 9-5 Arc Wagon 3.0 turbo) has a sticker that says Mobil 1

On 0w16 the engine is smoother, more responsive, quieter and consuming about 0.2L to 0.5L less fuel per 100 km.

Toyota OEM oil is very high quality stuff with lots of wonderful additives that are good for a long lasting engine.

To be honest, the mobil 1 ESP 0w-20 is a fantastic oil and meets those specs and is at walmart for $8/qt

My oil report on 0w30 mobil1 esp looked good. I'll keep using it. Mix of track and daily duty.

Seeing good results, lower heating, smoother functioning with Mobil Super Moto 15W-50 Synthetic Technology Engine Oil.

I was riding in the Himalayas where low-gear, high-acceleration could not be avoided and decided to try this. Noticed better performance, lower heating and decisively moved away from RE's semi-synthetic.

All 4 of my Subarus have serious consumption problems with Mobil 1. On my current 15 outback I tried liquid moly and it consumed it. I went back to the Subaru dealer parts department and so far 1200 miles the level is still full.

Yea mobile 1 is among the bottom end of full synthetics. Even the Walmart cheapest supertech and valvoline will slightly beat mobile 1 in reducing metal wearing.
