Doubt there would be any harm except to your wallet. 110 octane gas serves no useful purpose in your car.itchynackers said:I just saw 110 octane racing gas at a Citgo station. Is there any harm in running this stuff in my Z? Should I mix it with the 103? What do you think? It's $3.10 per gallon.
Highest unleaded I have ever seen is 104. Some tracks I go to have 104, some 100. 110 has always been leaded as Tony mentioned. Not good for your O2 sensors.ELF Z06 said:All the 110 race fuel that I've ever come across has been leaded. You cats and sensors are not going to be happy if it truly does have lead.
He is right 110 is leaded.Subdriver said:Highest unleaded I have ever seen is 104. Some tracks I go to have 104, some 100. 110 has always been leaded as Tony mentioned. Not good for your O2 sensors.
We have crap 91 here :yeadog: So I add some 100 octane for insurance at the track :thumb:Z06-Dave said:We did a test last summer. Using aviation fuel and 93 octane mixtures. According to the dyno, the car performed no better with more octane. Save your money and fill up with 93 or 94 at the pump. I made big difference in the turbo cars but none for ours.
Thanks for the heads up :thumb: But since I live my life a 1/4 mph at a time I don't put that much in.. I need all the weight reduction I can get :lol:Grim Reaper said:Kat mix five-six gallons of 100 with ten gallons Chevron/Shell. Anymore, is a waste, unless have your timing set to the moon(over 28 degress, small bore or 24 degrees big bore) or are doing F/I, Nitrous.
Also, calling our 91 octane gas, "crap"...you are being way to nice...filling our tanks with pure crap, would yield much more BTU's than the 91 that we have to pay extra for because it has to be made just for our wonderful smog Nazi state.
The ironic thing is that pcb's in the gas, coat the fuel senders and O2 sensors in the cars(they eventually malfunction) and make the cars run worse. Go figure.
Next time, I will tell you how I really feel.
As some have pointed out leaded fuel will not only destroy your O2 sensors; but I will add, your cats, heads, foul and burn your plugs MUCH faster, create havoc with your computer(due to a different burn rate) and eat your gaskets(unless they are copper). Other than that, it works great in a late model vette.
