What o2s can i use that wont foul with 110 i had the AC ones then they fouled now running bosch and im fouling them like every three weeks.

 

There are none that I am aware of that are comaptible with leaded fuel.

denso sensors are lead resistant, they should last at least a season before fouling

Sunoco makes an unleaded 104 octane race gas, which is their GT-Plus product name. Technically it isn’t a street legal, due to the fact it is oxygenated. That is what I run in my 396 stroker w/ 12.2-1 compression.

Kline, why do you need 110 octane?

 

I use VP Motorsport 103 and it is o2 sensor safe.

 

I believe the VP 103 unleaded is about the same as the Sunoco GT-Plus (104 octane).

11.3c.r +150n20, and i just fouled another o2 is there anyway of cleaning them? im going to start running 100 octane.

 

New o2 sensors and and some unleaded 100 octane should do the trick. If your set-up for nitrous was done right with all the bells and whistles, including colder plugs, I have no idea why you would run 110 leaded octane. 11.3 compression is really not that much. 93 octane pump gas should be just fine.

 

its a tune from madz28 for the nitrous, and i run colder plugs tr6.

 

You should be fine on 93 octane gas if the tune is setup for nitrous. Now if you were running a more aggressive tune I could see you needing race gas.

 

I run the Denso O2's on my 383 and have no problems with running AV100 LL or Torco 110, both of which are leaded (AV has 2.0gr/lead/gal, Torco 110 has 4.0gr/gal)
Incidentally in my area of the country I can now buy AV100 LL (which is between 110 and 115 R+M/2 pump octane) for less than pump 87 regular, and Torco 110 for $4.00/gal, which is only $0.25/gal more than pump premium.
Go figure.
