Engine oil Mobil or FUCHS

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.

Used Mobil 1 in all my Toyotas for the last 20 years. My dad's Scion xB is close to 400k miles running strong.

Funny, I changed my oil today for the first time as well. Also 1700 miles. Not black but certainly a lot darker than the Mobil One 0w40 that replaced it..

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