More results from my 3500Z!

Yes Densos hold up to leaded gas pretty good. One reason why I'm running one, they must be stout!

poor old wallet never catches a break.

LOL - neither does mine!

I feel sorry for you guys; I only have to go 10 miles to get Sunoco 260GT- 100 octane, unleaded race gas

Don't feel sorry for me... I have three stations with 100+ octane race fuel. One is unleaded the others are not. I will, however, let you feel sorry for my wallet, poor old wallet never catches a break.

Heated Denso brand O2's seem to last for a long period of time with leaded fuel, so I'm sure you already knew that though.

[IsaacHayes]

Lead will kill O2 sensors super fast too....

[Superdave]

been looking at U4.2. I'm not worried about the lead since i don't run a cat.

I'd have to wait till i can install a fuel cell and aftermarket pump.. i don't trust this OEM Camaro pump to stuff like that.. lol

[34blazer]

so your thinking of using nitro-methane huh? how about some vp U4?

[Superdave]

yeah xylene has a octane rating of 117 i think, heres a link on mixing for octane.....http://gnttype.org/techarea/misc/octanebooster.html

Those are things i've considered..



I've also thought of converting to alternative fuels for next year.. nitro-methane FTW!

It raises octane rating, but you loose mpg. The 87/89 is the same price here because it's the same thing. 87 with 10% ethanol added raises octane to 89. The last station here that was ethanol free had to switch and now everyones cars that filled up there have had miss fires/etc because they didn't clean the water out of their tanks properly so now it absorbed all that water. Some stations even tell you don't fill up a full tank, just a little at a time so you can help them get rid of their bad gas that way.... > I got much better mileage on straight gas I would pay the extra for 89 non ethanol because a tank lasted so much longer and end up being cheaper. (I had to run 89 in summer or I got pinging and KR and power went out the window)

You can add xylene or acetone to up octane. 3oz per 10 gal.

91 is higest we have here. And ALL the gas has 10% ethanol.

But I thought ethanol helps resist detonation by having a higher octane rating than gas?

[sprucegagt]

Some places do have 93 but they're hard to find anymore...

WOW. 93 is everywhere around here.
