My Mustang has had a steady diet of M1. I, then swapped this out to the M1-EP. I, must say the EP oil, until that time was my favorite oil, that I had run in this car.
I purchased 2 cases of the 5w30 Redline. The immediate impression was the car has never been quieter. After 5000 miles the car has required NO make-up oil, and still retains a good color.
Normally with the M1 I required a 1/2 quart make-up oil in 5000 mles. I plan a couple oil changes before sending in a sample for UOA. I have been impressed so far with the Redline product.
