You can run leaded fuel in your DSM. I've ran nothing but leaded Sunoco 110 in my street car for the past 18 months.
If anything, it keeps things cleaner. It even helps lubricate the valves. But "LD" is correct - it does shorten the lifespan of your O2 sensors. That's about the only disadvantage on a computer controlled car.
If you only plan to run it every now and then, like at the race track, then you won't have any problems at all.

Theres nothing clean about leaded gasoline, which is why it has been banned from pump distribution for highway vehicles since '95. The lubrication that you talk about is the lead deposits left on the valves, which also coats spark plugs, and everything else. This is why you need to change out your plugs much more often when running leaded race fuel. That lead use to build up on the valves in older engines and helped protect the seats as they were "soft". In todays engine that buildup, does just that buildup, on the seats and everything else.99gst_racer said:
With that said it is not extremely harmful to your car but lead is not the greatest thing in the world for your engine.

There's nothing clean about gasoline period. Hence, the need for gasoline combustion to be exhausted. Unleaded fuel causes build-up just the same. Quality of the fuel is key.TEC said:
The reason for it's banishment of public pump distribution is not because of it's uncleanliness (in terms of the engine), but rather because it is toxic. We all know that over exposure to lead is unhealthy and can cause brain damage and/or retardation, especially in small children. As more and more evidence of the damaging effects of lead came to light and the tree-huggers pushing for lower emissions, it was out with leaded fuel and in with catalytic converters.
The added lead in the fuel acted an a lubricant for the engine's internals. This build-up is merely a thin coating. The thin coating of lead prolonged the life of engines by relieving friction from parts such as valve seats and cylinder walls.
The fact that leaded fuel contains Tetra-ethyl lead is the only reason I use it though. The anti-knock features work wonders for controlling a high-boost/high-timing engine tune.
It does more good for an engine than harm, but much more harm to the enviroment than good.
PS - The phase out of leaded fuel was from 1976-86. Long before 1995....

I was just quoting the EPA:

and what I have seen.
Either way you play it, there's good reasons to run it.

The first line in that quote is very interesting.TEC said:
"Leaded gasoline will no longer be available in the United States after December 31, 1995."
This doesn't seem entirely accurate. Leaded fuel is still sold all over the US. You just can't pump it directly into your vehicle. I know this because I am a Sunoco dealer and I sell this stuff every day. I have three 500-gallon tanks here. I find it completely strange that a division of the EPA would publish a statement as bold and inaccurate as this.
And if you think about it, the date seems inaccurate as well. Being that catalytic converters were introduced to production automobiles in 1975, I highly doubt that it would take them 20 years to finally phase out leaded fuel.

They meant being able to buy it at a gas station pump, I think. There use to be a place near me that sold leaded race gas at their pump but around 199X they all of a sudden quit selling it even though there was usually always someone at that pump when I stopped in to get some on my way to the track.
they sell race gas at the local gas station here, but the hose is so short that you can only pump it into a container . I tried to pump some into my 91 talon but the hose was way to short. If the lead cuts the life of the o2 sensors short, by how much? How much should a beginner put in or is it ok to mix half 94 and half 11o.? Sorry trying not to thread jack.

Overseas, many people carry around nozzle adapters for this very reason.GotARed said:
I went through 122 gallons of race gas in my 2G last year and I'm still using the original O2 sensor up front. It's still outputing a good signal. I imagine I'll have to change it later this year though.rong. said:
O2 sensor life expectancy depends on the amount of leaded fuel consumed. I have yet to kill a sensor, so I'm not sure how much time and/or gallon consumed it will take.
