Engine oil Mobil or OEM Toyota

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.

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.

I stay away from Mobil 1 and Castrol because although they are everywhere they are not as good as they euro synthetics. In Europe they are not even legally considered synthetics. When I drain mobil1 it looks black and the engine is missing a quart...
