How much is it? What kind of results are you getting - and any problems?
Then do NOT pour in the whole bottle... On a FULL tank, you would probably want to use about 1/3 the bottle... that would get you to about 95 octane, if of course you had a true 93 to begine with... It adds 18 points per 5 gallons, 11 per 10, and 4 per 20 gallons... with a tank of 14 gallons or so, you'd be at a fairly accurate 100-102 octane... with a full bottle, and this will cause the car to run much richer and loose power... although, mine ran 10-1 A/F and made the same power before I added any timing.Mad Max said:I was more or less wanting to add a small volume of it to a tank of gas to ensure 93 or better octane - to avoid any internal motor problems due to a "bad" tank of gas.
Kind of like cheap insurance. That was my original intention.
