I pumped leaded gas into my Coupe, what to do?
I just pumped 112 Octane LEADED gas into my car by mistake, (idiot i know), I was at the race track and instead of unleaded i pumped the other one by mistake. ANYWAY i had about half a tank of 92octane in the tank already, and I added 5 gallons of 112octane LEADED, noticed it was leaded after I put the 5 gallons so I then finished it off with 5 more gallons of 100octane UNLEADED. As I drove my car through the night I heard a mild knocking, crackling coming from the engine, what damage can be done to my car because of this mistake? How can I fix it? What can I do??

I tried to cyphen it out but I guess our cars have an anti-cyphen valve in the tank to where we can't do it. I tried, and like 4 other people tried and we couldn't get the gas out. Plus I heard I had to take the back seat out in order to get to the drain of the gas tank. I ran it about 30miles after I put the gas in it. But remember I already had Half a tank of 92octane unleaded. Should I try to drain it now that I'm home and have more tools to mess with it, or would it be a waste of time since I drove it a lot?
Also does anyone know if infiniti will still warranty the car if the cats are fried?

Tetraethyl lead just contaminates the platnium in cats. Half a tank won't do much and the contamination will burn off eventually. Now repeated use will permanently destroy the cats after a few tanksful.
Since mid 90's the thickness of the EXPENSIVE materials has gotten thinner and thinner so don't compare old cats to new as far a robustness is concerned...........todays cats may only have a few grams of platnium dusted on the honeycomb core.

yea won't hurt if you did it once (won't hurt motor at all).
May want to change plugs depending on what plugs you are running, they will just get a coating. And yes if you ran it a bunch you can ruin your cats, and 02 sensors.....
Just think, you get that nice race-gas smell for 100 miles or soo.
