Hoping somebody could lend their $.02 on oil weight.
My bottom end was built fairly loose, with the clearance of my mains at .0024" and rods at .0021". I've got a 15W50 break-in oil in the car right now (first start-up is going to be tonight), but wondering what I should switch to after the first few oil changes (will switch to straight 40w after draining the 15W50). This car will be seeing the track (time attack-style events) and is set up with dual remote filters, remote thermostat, cooler, and -10 lines. Given the clearances, I'm leaning toward a 5W40 or 5W50 oil. Any suggestions?
