Engine oil Mobil or AMSOIL

I do 20k miles oil change interval on my RAV4. I use Mobile 1 extended performance and Fram Ultra filter. No problem at all

I use Mobil 1 ESP X2.

Available at Walmart.

It is approved by Mercedes and VW, it also meets the BMW requirement but is not approved by them.

I just go to Walmart and buy the big jug of mobile 1 high mileage engine oil and the most expensive oil filter I can find and just do the oil change in my driveway.

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.

I change oil once per year, using a high-quality synthetic that meets specification 504. I generally drive 8 to 9 thousand miles per year. The maker of the oil I use (Amsoil) says to follow the car maker's change interval.

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

For me at least, I use a 5w-30 Amsoil on my TLX Type S.

I wouldn't consider M1 4T to be the highest quality oil. It's a pretty standard Group III/IV synth blend with a motorcycle on the label.

If you run Mobil1, yes you will needs lots of extra oil... Mobil 1 doesn’t make the grade.
