Tried to get as much in the title as I could, but my UOA on my Evo will be back Thursday or Friday. 2003 Mitsubishi Evo, 122 cubic inches, 800 flywheel horsepower, E85 (ethanol) fuel, 40 psi of boost. Oil used was Valvoline VR1 20W50 CONVENTIONAL for 600 miles. Cmon, oil geeks, post up your guesses!!! The closest guess gets a ride in the car (if you come to upstate NY)
