Engine oil Castrol or Shell

I would order Shell Helix for £20/4L online instead.

i drive 85% freeway so i change the oil and oil filter every 7500 miles using Castrol Edge 0W-20 synthetic oil since 2017 no vehicle issue.

I put Castrol euro 5w-50 made for BMW and it's 6-7 liters and change it every 5000km I have a 2003 330ci and it still runs like new

5w40 VW 502 spec. Audi recommends Castrol so that's what I use.

I have used Shell Rotella T6 for 19 years on this engine with no issue.

Personally i never run ”GM” oil in my 95s anymore. I usually run Castrol edge 0-40

I ran this in my mk7 and my brother ran Castrol Edge Euro in his mk7. I have since sold mine but neither one of us had any type of engine/oil consumption issue and he still has with 130k on it.

Buy filters in bulk from RockAuto. Buy oil Castrol Euro Car from Walmart when it’s in sale.

I personally have used the RN17FE 0W-20 (Renault branded Castrol GTX bottles) for 10k km after the innitial oil that was filled in the factory (I don’t know which one was filled in factory). I haven’t noticed any better fuel economy but that can be tough to determine because I drove the car mainly through the winter and did more shorter trips than the original factory first fill oil that I drove with during spring and summer.

I tried Rotella when I first had my truck but it kept smelling like it was burning so I went to Valvoline Full Synthetic since it’s certified for Cummins.
