racing crude vs race synthetic oil?

[jenavet]

does anyone have any experience with the red line full synthetic oils? i have to drop my spare small block chevy race engine in this weekend and its a real hi rpm piece...the motor in the car now ive been launching around 4500 rpm,shifting at 6800 rpm and it goes through the traps around 7200 rpm.ive been using the valvoline 20w50 racing oil for about 200 passes and the motor has been performing flawlessly.this engine holds about 7.5 quarts and a case of the valvoline runs about 25.00

this spare motor i will launch around 5500 rpm,shift around 7600 and it will probably go through the traps around 8200rpm......the oil pan is custom with special kickouts and holds about 13 quarts.they say to warm up the motor with regular crude oil[for break in],then drop the oil and filter and then you can run the redline full synthetic race oil.....the problem is the redline oil is 7.99 a quart so that would be 104.00 to full the crankcase and 10.00 for a filter.....i usually put 15-25 passes on it per weekend and like to change the oil weekly or every second week......that would put me at between 228.00-456.00 per month just in oil and filters on this motor.

i love this motor and want to give it the best,but is it worth the extra 85.00 per oil change to run the race crude vs the redline synthetic race oil??

Hopefully Jen, Hib will see this before long - he knows his stuff when it comes to lubricants. I only worked in a refinery. :L
