I'm just curious; i've got about six thousand different opinions from people on the internet that heard from a friend's friend or read on some obscure website about the damage that leaded gas does to o2 sensors.
What i'm really wanting to know is how much does leaded gas affect o2 sensors? I mean can i run some 100 octane low lead and not hurt anything? maybe like 2-3 gallons; enough for a fun weekend at the track or will all my o2 sensors (bosch universl narrowband + bosch LSU wideband) melt down and create small worm holes distorting space-time continuum?!
I know dyno tuners use widebands with leaded gas; how else will they get the AFR's; but are they special widebands that are leaded gas friendly?
Also what about toluene; i've heard that can also eat up o2 sensors and foul plugs if used in excess.

So yeah; i'm just curious; I just got my little EF put back together with my greddy turbo'd d16a6 and the local track is having a $10 test-n-tune night friday night and i was kinda hoping to go out and run the Honda Of Fury™ (as my friends call my car). I blew the rings/lands on the last set of pistons being stupid and running 86 octane and forgot and boosted it with the cheap gas; so now i have fresh pisonts rings and what not. I thought about running some low lead race gas or gas/toluene mix if i can find some to keep me from making more papwerweights this weekend if i do run my car.

And to grab some free attention i'll post a pic of my old pistons



/edit: and just for the record i'm not the one that blew all 4 pistons. I bought the car like this but had no idea that this had happened. I thought maybe all honda's made an ugly rattle nasty sound and that it burned more oil than gas

 

ive been running VP 110, deluted with 103, and alittle unleaded 93.. for 3 months, no problems so far.. but i only run the car.. 1 time a week, and 100 miles to the track and back once a month.. so not real sure how many miles are on it.. but no real problems yet, i figure the seals would start going first on leaded gas

do you have a wideband or just a narrowband
