race gas in lawn mower

Hi guys,

I have a barrel of race gas that is leaking and need to use it up, I get the octane thing and know it will not make more power but what about the lead? My thought it is better lubrication etc... So i am about to burn it up in my small engines and my truck, I just want a second opinion that this will not cause a problem.

Thanks in advance
 
Running it in the lawn mower is fine. DO NOT run it in your truck, the lead will screw up the catalytic converter.
 
We forgot to fill up on our way back from Idaho a few years ago. All we had was 110 leaded sunoco mixed @ 32:1, put about 3 or 4 gallons of it in my F250 to make it to the next town with no problems. Don't see how it could be a problem if you already have a fair bit of gas in your tank.

Been running premix, race gas, av gas in our lawn mowers and pressure washers for years, smells great, and makes chores more enjoyable if you ask me!

Damage
[edit] Poisoning

Catalyst poisoning occurs when the catalytic converter is exposed to exhaust containing substances that coat the working surfaces, encapsulating the catalyst so that it cannot contact and treat the exhaust. The most notable contaminant is lead, so vehicles equipped with catalytic converters can only be run on unleaded gasoline. Other common catalyst poisons include manganese primarily from the gasoline additive MMT, and silicone which can enter the exhaust stream if the engine has a leak allowing coolant into the combustion chamber. Phosphorus is another catalyst contaminant. Although phosphorus is no longer used in gasoline, it (and zinc, another low-level catalyst contaminant) was until recently widely used in engine oil antiwear additives such as ZDDP. Beginning in 2006, a rapid phaseout of ZDDP in engine oils was begun.

Depending on the contaminant, catalyst poisoning can sometimes be reversed by running the engine under a very heavy load for an extended period of time. The increased exhaust temperature can sometimes liquefy or sublimate the contaminant, removing it from the catalytic surface. However, removal of lead deposits in this manner is usually not possible due to lead's high boiling point.

I had the same theory last year thought it would be great to smell race gas all summer. It cooked the rings in my lawn mower and i was smelling 10w30 for the rest of the summer:face-icon-small-fro. I bought a new mower with two years warranty for this year and has had nothing but straight c12 :face-icon-small-hap
 
I run my left-over race gas in my lawn mower every year. No problems.
 
My current plan is to use it up in my 1978 johnson 85 horse on my pontoon, any opinions on using it on the boat motor?
 
As long as the motors don't have oxygen sensors or catalytic converters, you can use it.
 
i use race gas in the quad.. yfz480..

i had to rejet it to run better on race gas.. Richer!!

I love the smell!!
