My plugs have a red tint to them on bank one. What does that mean?
super unleaded will do that
I have never seen that. Post pics. Sounds like maybe oxidation, or maybe oil burned on the plug.
is it bright red or like dark maroon?
that is the first indicator of snake oil booster....
use a MMT (metal based) booster and the red plugs will not happen.....the additives in 95+% booster create the red plugs.....
TORCO
OCTANIUM
NOS (RACING FORMULA)
are all MMT derived boosters.....they can achieve octane levels just shy of 100 and work great in my truck with LOTS of timing and NITROUS.....on a boosted application it would work wonders......
from a dollar per ocatane to 10 gallons of gas you can pretty well achieve the same results with 93 octane base fuel and adding 110/111 UNLEADED race gas.....buy 55 gallons and add 5 gallons to the tank right before a fill up when you need the extra timing.....this is my new plan i have yet to find the fuel supplier of choice yet.....i live right by an airport too so i may be buying aviation unleaded which i believe is 116....

Cut open for the pics would be my preference, but if you dont want to buy new plugs then just good quality pics will get us in the ballpark.
Now if they look like this:
It could be an octane booster, but only one bank makes me want to see yours. I know these plugs show many other engine problems, so I am glad they are not mine!!http://www.bowtie6.com/repairs/plug2.jpg
I did use some octane boost when I first started the truck. But I haven't used any since.
That might be the problem, they use a dye, are you sure the bank 2 plugs do not show the same? do they look like the red in the above pic?Quote:

More like the one on the very left i'd say. If it was lean wouldn't it throw a code for bank one?
As for using aviation fuel in an automobile, I've heard not to do it. Aviation fuel has an oxygenating additive that is there to replace oxygen not present at higher altitudes. Without the additive gasoline powered airplanes would lose power at high altitudes and sometimes die due to loading up on fuel.
At WOT you would not throw a lean code... Probably just melt the plugs, followed by the pistons or exhaust valves. Now if you where running very lean while your NB02s are giving input to the computer you will throw a lean code. Taking all you have said into consideration, and the fact the bank two plug is light brown, I would get new plugs, new gas and go enjoy the turbo.Quote:

If you use oxi-fuel... youll have to run more of it so as not to run lean... A tune for it would prolly work, with a wide band.
