Smh. You put that much through your cats amd you wont like it. Your talking like all that zinc and blah blah is gna protect your engine. Nope. That oil thick. Real thick. Your oil pressure will be higher because its like honey but will it lubricate better? No. I firmly believe in the 10psi per 1k rpm rule. You dont need a thicker oil just to race. You need to log oil pressure for that track and conditins to see what kind of weight you need. When tracking your car you nee to change the oil at 1500-2k miles anyway so those additives arent really important. In diesels that use this oil and are a completely different make up it beneficial as they may see 15k between changes.
With winter approaching that oil will be extremely hard on the motor at start up but its your car.
