Engine oil Shell or PENNZOIL

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

Pennzoil because it runs about 20°F colder for me.

Pennzoil. I've run conventional, semi synthetic, and full synthetic. Nearly 200k miles, still kicking like a mule. 7500 mile oil changes on the reg, some to 9000. No signs of slowing down.

Pennzoil ultra platinum often goes on sale or has rebates, I'll stock up a couple years supply when it does.

0W-30 VW 504 spec Penzoil Euro Platinum is all I use in my MK7.5.

Pennzoil has been pretty good to me. Not pushy.

Rotella 15-40. FTW

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

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).
