Engine oil Mobil or OEM Audi

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.

Stick with 5W50. Brand doesn’t matter as long as it’s a quality supplier. I used Mobil 1 in the beginning

Always used M1 on my 30 year old Celica/camry. They both run flawlessly. Done over 30 changes on the Celica (160k miles)

Mobil 1 has never failed me over 3 Wrx’s and 1 Brz and an old forester

I’ve only used this Mobil1 oil for my 21 Camry SE. I do 5k intervals and it’s been great for the past 60K.

I run 0W-40 Mobil 1 European that meets the spec on the bottle. 10k changes since new.

I will say I've done my last 3 oil changes with penzoil platinum and my engine rode rougher and louder than it did before with the Toyota oem oil. So this past time I tried mobil 1 and it's way quieter and rives smoother.

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.
