Re: Motor Oil
Racing oils are designed for racing, all out hard use. They don't contain anything to control acids from stop start and low engine temps during general street use. They also get replaced every race. Plenty of people use them for street and with good results but, like Bruce stated in post 13 most people don't have the mileage on their engine really know if the oil they are using is best suited for their application, myself included.
One of my small blocks I've had for 30 years and have ran so many different oils in it over the years I don't know which was best because I rarely did oil analysis on it.
The other SB is new and wanted to stick with one oil so after lots of reading and asking questions, gathering opinions and comparing, I settled on Amsoil Z-rod full synthetic and I can only hope it performs as stated and give that engine a long service life.
I almost went for the Schaeffer posted above but, the Amsoil was more available to me.
