Engine oil Mobil or Kendall

I went back and forth between Mobile 1 and Amazon full synth for 140k miles without issue. Just change the oil every 5000-7000 miles

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.

My wife drove her 2008 Passat 2 miles per day for six years. As you can imagine, during these very short drives in winter, the oil became diluted - this was born from sever UOAs. So, I changed the oil every 1,500 miles and the oil and filter every 3,000 miles. Over-kill perhaps but based upon my personal expectations, worth the time and money. We used Mobil 1 0W40....which sheared to a 0W30 fairly quickly and stabilized.

my valvetrain was always noisier when I used to run Mo1 0w40.
