Had 3/4 full tank of 93 octane and topped off with 5 gal. of 110 octane racing fuel just to see the difference. Noticible difference, but is this safe for a stock motor with Steeda CAI, 93 oct. tune, and UDPs?
even though the gas tank is supposedly 16 gallons, ive never put more than a hair over 14 in while on empty, so ya either he had less than 3/4 of a tank, or didnt put 5 gallons in.how did you have a 3/4 full tank and put in 5 gallons? Wouldnt that overflow it?
