Duncan4169 Posted May 13, 2012 Report Share Posted May 13, 2012 I have seen the 108 boosters are these worth running or is 91 just fine ? Link to comment Share on other sites More sharing options...
Wayne Grey Posted May 13, 2012 Report Share Posted May 13, 2012 All Stock ? If so manufacturer's recommendation is fine. Octaine booster would be a waste of money. Link to comment Share on other sites More sharing options...

JeffIsHereToo Posted May 14, 2012 Report Share Posted May 14, 2012 Those cheap bottles of crap you buy at Autozone can actually damage your engine. +1 unless your tune requires it...more is not always a good thing! Link to comment Share on other sites More sharing options...
TheKurgan Posted May 15, 2012 Report Share Posted May 15, 2012 http://www.amazon.com/Octane-Booster-Quarts-Torco-Accelerator/dp/B005S2BKDQ Since I moved, there is no 93 available around here. I've gone through a case of this so far. Getting ready to order another one. Link to comment Share on other sites More sharing options...
rhlgt500 Posted May 15, 2012 Report Share Posted May 15, 2012 Have yet to find 93 Octane in California. When breaking in my '11, and for sometime after, I'd mix in some 100 Octane racing gas with the 91 Octane that is normally available at the pump. 100 Octane is available at a very random smattering of stations across California, two happen to be within 5 miles or so of my house. (One wild rumor I heard was the Saratoga 76 station added the 100 Octane pump to make a local Veyron owner happy.) One must be willing to empty ones wallet at the pumps for this to work, 100 Octane is insanely expensive.. I've sort of given up the mixing habit. At 15K miles the car isn't new and I baby it a bit less, and i just didn't really notice any difference in performance. In theory, the difference between 93 and 91 should be well within the scope of the stock tune to deal with such that the engine doesn't take damage (or Ford really shouldn't be selling GT500's in California). There are mix ratio calculators out there, like this one. http://www.wallaceracing.com/octane-mix-calc.php Link to comment Share on other sites More sharing options...
