Engine oil Mobil or Mannol

Mobil 1, Valvoline, or Motorcraft. Ive used them all and have no complaints so far, usually i use Mobil 1 since i can find the 6 qt box for a decent price at Costco.

I personally use Mobil 1. They all do basically the same thing if you're changing it often enough. I change mine between 3-5k miles typically.

I used the mobile advanced fuel economy, I live in a pretty mild climate. I have seen lots of people swear by asmoil it's supposed to be good.

From my own experiences, M1 is excellent. Been putting it in my 30 year old Celica for 7 years, gotten 160k miles out of it, 320k miles on the original motor in total. My buddy’s Corolla had a bad timing chain slap on startup, went dead silent ever since swapping him over to M1. I just stick to what I know.

I’ve used Mobile 1 full synthetic for years, most manufacturers warranty it.

i have a 5qt of Mobil 1 sitting around in case i ever need to take it in for warranty work.

I run Mobil 1 15w50 in Colorado in my 1.8 8v 85 GTi. For camshaft insurance I add a zinc additive at oil change time.

I use Mobil 1 15W50 zddp conent is higher than regular oil.

Usually, motor oil goes bad because the additive packs that are in the oil get burned off or used up. I'd imagine that this new Mobil1 Annual Performance has more additive packs than what standard Mobil1 has but it's probably able to go that far because you're going to have to add additional oil that gets burned off because every car burns oil.

I used 0-40 mobil 1. It turned out pretty bad for me, I ended up using more oil than I ever had before. The car smelled like a friggin chainsaw with that stuff. The engine only had like 100k on it, but the blowby was horrible with 0-40. This was just my experience. I use mobil 10-40 now and no problems so far.
