i put 110 octane in my formula and now it runs rich...
i used to put itin my v6 and it ran good in there.. any ideas to lean it out..
thanks

 

There is no 110 octane unleaded fuel available (103 is the max) so you must have used leaded fuel. Possible the lead destroyed the O2 sensors, and that's why its running rich.

 

WHY...... THE.......HELL


would you put 110 octane in your car???


hell... why would you put 100 octane in your car?!?!?!?




why not diesel?

or water?

****... how bout molassus?


tartar sauce works well too..

 

u dont hav to be a smart ***... i put it inmy v6 and it ran way better with it in there
it was at a pump and it was 110 and its unleaded gas for sure
i only put 2 gallons of it and 3 gallons of 93..

 

they sell 110 UL at some of the gas stations around here. Its racing gas. theres no need for it in a stock car... especially since its like 4 bucks a gallon

 

actually we have 104 unleaded here! just letting you know! but yea there is NO UNLEADED 110

 

im callin BS on that! not saying that your a liar im just saying that i think you dont know for sure go get a reciept that says 110 unleaded! im almost positive that it will say 110 leaded

 

hmm maybe you're right. Its what we use in our racecar. i didn't think they had leaded gas at gas stations ne more...

 

VP makes 103 octane unleaded. It's called "Motorsport 103". The motor octane is 99 and the R+M/2 is listed as 103 which implies a research octane of 107. Sunoco "GT Plus" has a motor octane of 99 and research octane of 109, so R+M/2 = 104 octane.

AFAIK these are the highest octane unleaded fuels available.

so is it the gas makingit run rich i got the gas at agasstation called texaco in va.is said 110 on the pump didnt say leaded or unleaded but im still wondering if its the gas doing that to my car?

 

I just had an idea, it's Possible the lead destroyed the O2 sensors, and that's why its running rich. You may want to check the O2 sensors and see if they're working right.

I know what Sunoco and VP fuels make. They do not make 110-octane unleaded. A lot of people run VP fuels C-10 and assume is it 110 octane.... it isn't... its 100 octane unleaded. Sunoco advertises their GT Plus 104 as "one of the highest octane unleaded fuels available."... and it is at 104 octane. They also do not recommend it for street engines, since it is so highly oxygenated.

Your V6 runs better on 110 octane fuel? ....

You toasted the sensors with leaded fuel, IMHO.

 

is there a way to test your O2 sensors? My cars been running rich for quite some time, and went from about 25mph on the freeway to <20... no check engine light
