After 631 miles and less than a 1/2 quart of
oil (10W40 non
synthetic) used on the upgrades and repairs to the engine in ERA717, I am switching to MPT "Thirty-K" 10W40. This is a full
synthetic motor
oil and was recommended to me by my good friend, racer, and race shop owner in northern, NJ. He used it in his race car all season long with wonderful results, wants me to test it on the street in my motor knowing the documentation I did over the course of the first 631 miles. I will update my thread as mileage progresses on the car.
