Engine oil Mobil or PENNZOIL

mobile 1 is a good brand. id go with it

Why not just buy the Mobil 1 and take it to the dealer?

My 2925 Passat is happy on the Mobil 1 esp synthetic.

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.

I was running Mobil 1 for many years in my 14 ST3 and started with Mobil 1 in my now 16 ST3 but this year I swapped to Walmart brand full synthetic and haven't had a single issue except for extra cash in my wallet. It meets all the specs and I change it every 5 thousand miles regardless of how the car is driven. I'm at 86 k now on the odometer and she still pulls string like the day I picked her up.

I have never seen my 2017 Jetta low on the dip stick. I usually change it about every 5k miles using Mobil 1.

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

I've personally run Mobile 1 full synthetic for 10k intervals ever since the factory oil changes ran out without issues.

Not saying it is better than anything else, but on my G60 turbo i used Mobile1 FS-X 5w-50 and will continue with this oil on my PG/ABA turbo.
