the setup i am running said i need to run a minimum of 104 octane, i cant find any around here. i found 101(unleaded) and 116 (leaded) . if i calculate right, mixing 4 gallons of 101 and 1 gallon of 116 will yield right at 104 or just a hair above. my main question is with the 1 gallon of leaded in the mix, will it be to much lead to screw up the O2's or not? i am just trying to figure out the best way to mix the fuels, any info would be greatly appreciated, thanx

If it were me I would add a can of Torco to the 101 and test for kr. Probably be all you'll need. You can also buy 104 unleaded from Sunoco by the drum.....over time the lead will kill the o2's and the cats (if you use them).

from what I have read, for whatever thats worth, 50/50 leaded/unleaded will knock 90% off the life of heated O2 sensor. I just bought a drum of the 104 and use it at the track, cheap insurance and I know exactly what I'm pouring in there.

unleaded gas is for girlie men. Just buy some Denso sensors. They resist lead poisoning very well. Most of the GN guys seem to be getting 25-30 gallons of straight c16 through them before they notice them getting lazy.

I run my car on gas that has a low lead content when I race and i've put 20 gallons through the car with ZERO O2 issues so far, including 5 gallons of c16. I am running the denso sensors though since I love leaded gas

well 100 bucks for regular O2s and 50.00 for the wideband sensor every 25-30 gallons and I'll just keep buying the unleaded 104 for 4.80 a gallon to run at the track and be girly I already went through 15 gallons this year and I drive a lot but I use 93 to cruise on.

Only thing I cant stand about unleaded is the smell out the tailpipe but the 104 smells like manly fuel so my friends dont laugh at me

my wideband is the NTK L2H2 (5k-10k miles), luckily it too is lead resistant more than the bosch LSU4 sensors (50-500 miles). The NTK sensors cost about $200 each though!!!

NTKs take the lead better then the LSU but dont drop the thing LH1/2s used to be fairly cheap until they figured out what people were using them for, supposedly stopped production and then doubled the price

id try running your own special mix. like say 70% pump 93 and 30% acetone will give you 108. so will 30% some other paint chemicals like xylene and toulene i believe. so a search on it and youll see. screw buying new O2's for leaded gas, youd be broke ina year...

How true is that though KP? Damned pump gas smells nasty and it's a "breath of fresh air" every time I get to the drag strip. Something about the sweet smell of octane. There is always methonal injection.

104 unleaded smells like real gas, not that sweet C16 smell but way better then 93. Only bad theing is the MMT or whatever they use turns everything brown after a while - wonder if thats just as bad as the lead on the sensors

well i ended up finding some unleaded 118 and mixed 3.9 gallons of 101 to 1.1 gallons of 118 and it worked fine, no detonation problems.

neither had i, it was like 7.95 a gallon at a shop around here, i asked him 4 times and he promised it was unleaded and made for nitrous in the newer O2 sensor cars
