Engine oil Mobil or AMSOIL

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

The best oil you can get for that car is the amsoil signature series. 0w30 or 5W30 in warm climate.

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.

I switched over to Amsoil and I the engine runs much better.

I take my own oil to my mechanics shop. I use Amsoil Signature in my Challenger.

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

I use it on my 22 street Bob. My mechanic swears amsoil will make it run cooler but idk. I’m going to try the amsoil when my 10k comes up soon. I’ll always run synthetic either way.

I have personal experience with using amsoil in a Cadillac Northstar which are notorious for burning. It did stop that in that car

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

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.
