No offense taken :bigok: I think I will research the whole octane issue a little more. I just brought it up because everybody was bitching when they dropped to 91. So that made me curious about supplemental products.

 

oh, and thanks sinful7. btw feb. 11th's answer is B.

 

I didn't read the other posts but I can tell you that octane booster uses microscopic particals of Magnisium to cheat the octane rating so if you want little pieces of metel running directly into your motor have fun.

 

imho..

id mix high octane race fuel to increase if your limited to 91..

elevation is another factor to consider...

my trip from CA to NJ resulted in not seeing anything above 92 till the eastern portion of TX..

had to use octane boosters... as race fuel was not convenient....

just note that race fuel is leaded and your o2 sensor at this point is susceptible..

that is..if your still retaining it..
