Engine oil Mobil or Castrol

I'm using Mobil 0w-20, no problems here.

Last change I did was with Castrol Edge 0w-20 no issues.

I've always run conventional Castrol 20/50 in my Gti's (past and current Turbo) without issue.

I have been using Mobil1 for a long time in all my cars. AFAIK it has performed will in independent testing for this car as well but the consensus is that the shell rotella is the best stuff you can get. i have also recently switched to 5w20 instead of 0w20 because i live in a climate where it never really gets cold and i wanted something a touch heavier for auto-x abuse. most people agree that we are talking about a very minor difference at best, but it does feel a touch smoother now.

Mobil 1 15W50 [emoji106] Has plenty of ZDDP

Castrol Edge 0W40 A3/B4 (European Formula), about 27$ per 5 quart jug at Walmart. Made in either Germany or Belgium. A real synthetic, Type-4 PAO based (no Type 3). Meets the strictest oil requirements from ze Germans.

12 Galant 2.4 always running Castrol edge 5w20 and oil filter change every 5k miles for like 60k miles now has 126k. Cars have never shut off or left me stranded or left any signs of hesitation.

I have used Mobil one for 25yrs and never had an engine problem. I have a 1978 Alfa that uses Mobil one for most of it's life when the oil was released and the engine is perfect.

For oil changes, use BMW, Mahle, or Mann filters and any LL-01 approved oil. Mobil1 0w40 is what I've been using and never had any problem.

Generally, brand matters a lot. Amsoil, Mobil 1, and Castrol are all great.

I run Castrol in my older cars and Mobil 1 in newer cars that I care more about.
