Engine oil Mobil or VALVOLINE
M1 ESP is arguably the best oil out there. It does not shear fast, doesnt degrade with 5% fuel dilution.
I run Mobil in all my cars. The regular 0W-40 is cheap and easy to get, as is the 5W-30 ESP for the RS3. Right from Walmart.
Extra info, I have seen some stuff about valvoline. Engine looks pretty clean inside after they ran valvoline restore and protect.
Change your oil to Valvoline Restore and Protect 5W-30! Change every 3000 miles, filter too!!!!!
Valvoline is the best and bang for the buck for me.
Mobil1 is $25 a jug at the Walmart, my Blackstone Labs reports say it would be fine if I wanted to extend it well beyond the factory 6k interval.
I noticed a massive difference switching from 0w-30 to Mobil 1 FS 5w-40 in my NG 93. Engine sounded better, burned WAY less oil, and no noticeable fuel economy or power difference. I also used Ceratec a few times and that made it feel smoother.
Ran quieter on 5-40 heavy duty diesel Mobil 1
Felt more powerful, but that may have been a perception from quieter and smoother power. Others on Saabnet reported the same.
Mobil 1. Used to be a valvoline guy but my motor blew up lol. Dont think brand had anything to do with it, just felt like shaking things up.
Valvoline is pure trash. Hardly any additives between any other lines of oil compared to competing brands.
