Is it ok to run 5 gallons of 108 leaded I dont have cats but will this kill anything by running it this one time? I bought 5 gallons of C12 108 octane. 4.23grams per gallon of lead.

Re: Is it ok to run 5 gallons of 108 leaded Well goign to hope for the best. The car been siting for awhile and I needed to put something in it to raise the octane lvl. Hopefully I just have to change the oil.
Re: Is it ok to run 5 gallons of 108 leaded I've ran 40 gallons(not in a row) of 110 Leaded through my blown stang before and it didn't hurt the o2's. But I have seen it where my buddy put 5 gallons in one time and it took out both of his so......

Re: Is it ok to run 5 gallons of 108 leaded It will eventually kill the sensors
You passenger side sensor will set a code first, it's farther away and cooler due to the loaction of the sensors with the turbos.
you will eventually get insufficienty switching codes on both sensors. You may not get it with one tank, but you just might. I think i did on the first tank.
Your fuel trims will rise as well, the lean to rich transition is the one that slows the most when running leaded fuel. I logged consistant shifts in the l-trims of 5% to 8% on the rich side.
Other than sensor fouling, there's not much it will hurt. I ran 4 gallons of 110 to every tank, 500 miles a week when the car was in one piece. Did that for about 10 months <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
