110 leaded or 100 unleaded race fuels for the evo?
That mitsuatb is a fuc.king Bit.ch, I swear he just wants to argue. Maybe he is mad he is riding around in a LT1 instead of an LS1, oh well. I used to own LT1's with my T-25 (READ SMALL!!!!) TSI AWD with boltons.....

I guess the other guys are too insecure to learn anything from anyone.
Information is always welcome.. Ego is not.. Sometimes people don't always understand a complex technical reason for something and it requires a bit more explanation or a simpler answer, its no reason to get upset. The guy was just being sarcastic. I find it offensive that you used the term "Dumb it down", its just uncalled for. Intelligence isn't just about knowing the right answer, but being able to communicate it.
Now, as to the answer to the question, Everyone is more or less correct about why you don't generally use leaded gas in a car equipped with O2 sensors... Basically over time (quite a while) it will damage the Sensor.. If you have a catalytic converter, the crud in the exhaust of leaded gas (the 'white soot') plugs up the catalytic converter.
If you do not run a catalytic converter, you can OCCASIONALLY run leaded gas.. If you run it all the time, expect to replace your O2 sensors around once a year (expect to spend $75-$100). They don't immediately fail, but become innacurate over time, and can ruin your closed loop, part throttle drivability until they no longer function correctly at all. The car then runs in open loop, basically the mode the car runs in when you first start it before it warms up, and you know how stinky rich and poorly it feels until its out of that mode..

I am sure of one thing, after reading the posts I will NEVER buy a used EVO.
Telling people that it is ok to run leaded gas is criminal, both illegal and damaging to the engine sensors for no good reason.
Octane is Octane, run all of the unleaded race gas you want there is no advantage to lead unless you have cast iron heads with no valve seats and need the lead to prevent valve erosion into the heads. Example, and old Hemi engine from the 60's ect.
No need to flame me, I won't read the posts on this topic anymore.
Posting to this site is like throwing meat to a bunch of stay dogs, no appreciation and they will bite you if they can.
If this is how Evo owers are going to act, it is another reason to keep my money in the bank and not buy one.

AUTHOR,
1. You can run leaded in a catless exhausted Evo.Yet you'll stay up nights worring about when the 02's go..
2. 100 unleaded is very efficient..but even then mix with 93 abit.
good luck
yeah i worried my a-ss off when i put in 2 gallons of 100 leaded in my car.. i've since gotten over it.. but iwas worried.. those 02's tell the engine almost everything.. Sans intake information.
100 UNLEADED IS WHAT YOU SHOULD
OH AND LS1' LOSING TO TSI'S ....LOL.. OK BRING IT AUTO'S WITH STALLS AND GEARS AND NITTO'S LAUNCH LIKE CATAPULTS.. AND IT SUFFERS NO 20-150 THEY PULL SCARY HARD
HARD MUCH HARDER THAN GEN 1&2 AWD MITSHU'S

If you are running a cat, DO NOT run leaded. It will trash it super fast.
A little, once in a while probably won't hurt.
My buddy runs Aviation gas (leaded 105). He has been running a tank full about once a month for over a year. No problems yet.

why don't you make your own race gas. i know the some of the DSM people have done it for sometime now

Anyone who wants to protect a cheap assed stock O2 sensor by buying 100 octan unleaded for a couple bucks a gallon MORE than 117 octan leaded feel free.
Anyone who would refuse to buy a used EVO because they may have to replace a $100 sensor is a fool. No doubts, no exceptions.

Lowest I have EVER seen 100 unleaded was right around $4.30 a gallon. Where did you see it for $2.89?Actually since I have an expensive wide band O2 sensor that is much more seseptible to lead poisoning than a standard O2 sensor I run VP racings MS 109 (it is actually 109 RON 101 MON giving you 105 octan MON+RON/2) when I want to crank up the boost a bit. That runs me $5.75 a gallon compared to $4.32 a gallon for the same octane in leaded fuel. If I go through 100 gallons of race fuel in a year (and actually I go through a LOT more than that) I would save more than the cost of replacing both of the stock O2 sensors by running the leaded instead of the unleaded. For lower cost ($5.37 a gallon) I can get leaded fuel with 107 MON 113 RON (110 octane RON+MON/2) rating and still save money in the long run over using unleaded!

As it sits I will only run the 105 unleaded at the track. Hell the only 105 uleaded I have used so far was for tunning the AEM EMS to get ready for the track! Every Tuesday night is open test and tune in Indianapolis..... every Tuesday night that I am not working it rains! I used up around 15 gal of 100 unleaded back when I had the SAFCII between tunning and running at the track. So far I have used a total of about 30 gal of race fuel and that is without being able to hit the track much due to the rain.
