I found that the half quart from full to half went very fast. From half to add it took much longer. I did try the 40 wt. Valvoline and it did not burn as much but I am sticking with the 20-50 Mobil 1. I think that operating temp has a lot to do with it.

To cruise a Formula 400 @ over 40 mph probably takes a reasonably high RPM. My experience has always been that the higher the RPM, the higher the oil use. I cruise at 3500 @ 52 MPH and seldom if ever add oil. I use Mobil One 15-50 and keep it very fresh with 25 hr change intervals.

IMOA if you change oil brands or type ((like going to syn.)) sometimetimes the new additive package will cause the motor to use oil a short time then stop ,Syn. is better at lasting as its harder to burn and ron above is right forged piston motors are prone to us alittle oil . J&E piston that come in 502's use a tighter clerance and thats a big reason Merc uses them they really make a good part ( thats why most cup teams run the J&E's is the clearance issue,tight and very tough ))
