Engine oil Shell or RAVENOL

Worry less about the now old 502.00 spec than the actual oil itself. It's API SN/CF and has MB-Approval 226.5/ 229.31/ 229.51. Even though 505.00 and 505.01 are diesel engine specs, it should be fine in your older car. One of my go-to oils is Shell Rotella T6, which is specifically for diesels, but it's a great oil.

Its honestly all good, I ran Rotella T4 for a while, still good.

I'm a big Brotella Bro. I've used Rotella T6 in my WRXs, Miata, sport bikes, and dirt bike.

I suggest running Shell t6 5w40

In Germany we driver Ravenol RCS 5w-40 and Archoil 9100....sick combination. i drive it in my c63s and gle63s and volvo S60....

Rotella 15-40. FTW

I run this one in our 04 BEW TDI. No issues what so ever!

I think the Ravenol VSE 0W-20 is a good performer, based on these tests.

Just to add my two cents, I am using Shell Helix Ultra ECT C2/C3 0W30 (it is basically the same as Pennzoil Euro 0W30 in the US) in my AGU 1.8T (150bhp) after I have killed an AGN 1.8 (125bhp) by using 10W50 for about 8k miles (I was flooring it a lot). I bought an oil pressure and an oil temp gauge after I have killed the 1.8, and the oil pressure seems to be perfect with the 0W30 (the engine has about 100k miles on it).

Just get good oil. T6 is one of the best oils for EJs and it’s dirt cheap.
