Racing fuel?

[SANTEEN]

Probably going to the track again this Friday. There is a Sunoco gas station near me that sells 100 low lead racing fuel. I plan on flashing my PCM with a 96+ tune. Will our trucks be okay with low lead fuel?

should be, if they have the 104 that would be better.

Cool. So low lead is okay? Do I need any additive to put in?

If it is truly 100 Low Lead, it will foul your cats and 02 sensors in about 50 hours of run time. You will want the 100 Unleaded.

I have no cats and I'm mixing it with 93 octane. I only plan on running it through this tank and probbaly not again until I go racing again. Will it still hurt the sensors, even mixing it?

the 104 ultra premium shouldnt hurt it. i ran it on my trk with the ROE with Sean's 101 tune before and after i deleted the cats. if your catless your fine it wont hurt the sensors

Apparently this particular station only has the 100 low lead and 112 leaded

I have ran probably 100+ gallons of 110 leaded thru my truck without issue..........it will eventially damage the O2 sensors but so far mine are working perfectly (had my dealer check them with the starscan about 2 months ago).......

I have no cats so no problem there for me...I would not run leaded (even low lead) with cats...they will damage quickly and might not be noticable..................since you are catless you should be fine with the low lead 100 octane..
