Best Engine oil for Ford Mustang

After 12 years and 45K miles. I took a 05 Mustang and added a supercharger. For the next three years , and 15K miles, I took it drag racing and high performance track day driving. Wanting more horsepower, I had the engine rebuilt with forged performance parts. When the engine builder measured the wear in the block, everything was still within factory specifications. I had used Amsoil for the life of the car.

I used Mobil 1 with my Mustang. I like it for my timing chain and valve line. It’s very good. Car runs quiet.

I have been told the same by Blackstone on my cars, though I still do it once a year given the cost is <$75. However, I do follow their advice on intervals, after once being a 5,000 mile interval guy. On all three of our cars, using Castrol Edge 5W-20, I've repeatedly gotten analysis that tells me that, at 7,500-10,000 miles, the oil is still performing as intended.

Amsoil 5W30 SS, I run E85 so I wanted something I could trust to handle fuel dilution

I use Valvoline Extended Protection, it's really good stuff

Mobil 1. I've used it in all of my cars. Two of my mustangs lasted until 240k before needing a rebuild.

On a side note, if anyone really wants to see what their oil change interval should be, just get an actual oil sample analysis done. Per the lab reports, I can get 8k miles on quality synthetics and still have a good safe margin for oil life.

I red-line 1st and 2nd gear when merging onto highways from the on-ramp. But then cruise at 100 kmph on the right lane. Gotta have fun when you can! Ensure that **oil** temps are good, not just the coolant.

When we tested Mobil 1 on the racecars on the dyno Mobil 1 freed up 6-9 hp over other oils using the same Ford viscosity - 0w/20W.
