Engine oil Mobil or RED LINE

Mobil 1 full synthetic. Been using it in all of my cars for years. No issues with burning oil or anything.

Didn't double check, but I bought [this](https://www.speedwaymotors.com/Mobil-1-Supercar-Full-Synthetic-Motor-Oil-0W-40-Dexos-R-Case-6,495272.html).

Mine arrived as advertised.

There's literally only one oil that is certified for use in our cars: Mobil 1 Supercar. Nothing else has the proper Dexos R certification.

Been using mobile 1 5w-40 Syn Euro. Fixed my vanos code.

I use 0w-40 euro blend Mobil 1 in the winter and royal purple 5w-30 in the summer and usually try to get an k&n filter or something of similar quality it’s not always about the name but its definitely worth some research

I do not use auto oil. Motorcycles run hotter and I don’t trust car oil. I use Red Line. They sell a V-Twin kit that has engine oil primary oil and transmission oil, and fuel system cleaner. I buy one each spring.

For my Z with 210k miles i switched to the one your holding and it burns less. I get an extra 150 to 200 extra miles compared to mobile 1.

I always use full synthetic Mobil 1 5W-30

My 1.8T has just over 103k miles. I got it at 78k, and until about the 95k mile mark, I've been using M1 0W-40, then switched to M1 5w-40 Truck and Turbo-diesel, since I wanted peace of mind with its extra additives and protection. I figured since this oil is meant for high operating temps and high load in turbo-diesel engines, it would be just as good in my daily-driven and weekend-tracked 1.8T. I change my oil a few days before going to beat on it over the weekend, otherwise I'll change it every 3k to 5k miles. Also, I have had some valve noise (tapping of some sort), the whole time I've had the car. I'm guessing it's lifter noise. I'm not sure, but I was told to try a heavier weight to counteract it, hence the switch to the only decent 5W-40 sold on base. Still no difference in noise.

I ran M-1 15w50 for 10k miles or so, and my car ran 10 degrees hotter on average than with any other oil I've used. Throttle response also felt sluggish.
