I just put 110 octane fuel in my car yesterday, it runs a higher boost and it pulls a little harder. i was wondering what the implications would be to doing this often. is it a good or bad thing for your engine overall?

 

You will screw your cat up quicker. Our cars aren't meant to run on this octane.

 

only if its leaded.

 

Exactly. You will experience lead fouling and screw up your plugs and valves. And it probably isn't street legal anyway.

 

It would depend on if it is leaded or not. If it is not then it should be OK depending on if it has methanol, MMT in it or not. Bottom line is to know what is in that gas before you put it in your car....

 

i use 101 mixed with the 91 we have here in phoeniz , my cav seams to like it better under boost

 

110, i believe is considered low lead, my redline runs slower since i ran a half tank in it of 110 low lead, think i fouled the cat out, i need to put some sea foam in the crank case to get everything cleaned up....
