Engine oil Mobil or MOTUL

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.

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.

If you're oil change is specified for longer, buy Mobil 1 in the correct spec grade and change it then, you will save money and use less, which will keep your cash in your pocket not the oil industry's.

Very impressed with Motul tho I had Motul but I got tired spending $70 for 4k mile oil changes.

I used to run 8100 Xclean EFE 5w30 for the last 5 years in my 2019 FA20Dit.

I use motul in my heavily modified car though because it’s just that good.

I’ve (mostly) only used Motul in my scooters. Only destroyed two engines and the oil wasn’t to blame. (I was.)

Syn 3 is garbage. I typically run mobil 1 full synthetic (twin cam) or motul and motul for other stuff since they have dedicated lines for primary, oil etc.
