Engine oil Mobil or FUCHS

Not going to lie. I use Walmart auto for my oil changes. If you synthetic premium you can pick your own oil, I use Mobil one.

Mobil 1 full synthetic and Mobil 1 filter. I did cams recently on my GT and at 150k, the top end looks almost new.

I’ve been using Mobil1 0w-30 in it for over 20 years. My Blackstone Labs reports still come back clean with no water, fuel or antifreeze found in the oil.

What brand oil are you using? I noticed a decrease in consumption with Mobil 1 and stuck with it.

Mobil one..yes they make ac delco oil, but the additive package is a little better with m1 vs Delco.

Mobil 1 hands down. There's better but not as consistent for the price.

I’ve been using Mobil 1 in all of my vehicles and other equipment for 20+ years, never had a problem with it at all.

On my 2015 CC with a Unitronic Stage 1 tune, I use Mobil1 Euro 5w-40. I sent a sample to Blackstone at ~7200 miles and they said I had plenty left. I change at 8500.

I run 10-40 mobil1 in my VR now. had 5-30 and it ran just about the same, didnt notice any difference really.

Fellas, Don't bother running Mobil1 for extended period of time. I have done 2 consecutive oil tests on Mobil1 0W-40. One with 6200 miles and the other was at 4700 miles. Used OEM filters in both cases. Results: With the 6200 mile drain interval, the iron and the lead levels were up there through the roof! With the 4700 mile drain interval, the iron was within average and the lead was couple of points above the average.
