Engine oil Mobil or Shell

Been using Mobil 1 5w-30 full synthetic since I rolled it off the lot. Zero issues. I do my own changes every 3-5k. I did swap out to the FL400s filter to make it an even 6qts.

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.

That Mobil 1 5w-30 has a tendency to burn off, so it might be a bad combo.

i got a little valve clatter when i went to 0w40 on my next oil change i'll be using 5w40 (synthetic)
