FURAFURA Posted April 4, 2013 Report Share Posted April 4, 2013 Guys, I'm installing the 675HP Roush kit to my Roush on Tuesday. Roush says good for 91 or 93 gas, but I know 93 would be best! Sadly, they don't sell 93 in Puerto Rico anymore only 87 and 91. Can I use a bottle of AMSOIL Dominator Octane boost every time I fill it up? wont harm the engine? will raise to 93? the 12 once bottle don't specify how more octane I would get. It's one once per gallon? Or any better suggestion. Link to comment Share on other sites More sharing options...
Torched10 Posted April 5, 2013 Report Share Posted April 5, 2013 heres an interesting read thru a gooogle search http://members.rennlist.com/951_racerx/OctaneBoosterComparison.html I have read in other places that usinf boost too often isnt good for the engine. I use it in my 65GTO whoch has 11.5 to 1 compression and we have 93 oct gas available here in atl and i can tell the diffreence with alot less pre-detonation Link to comment Share on other sites More sharing options...
