unleaded vs leaded

Juanita --Tempted to say no problem here. But maybe one of the more technical guys can back me up but the stuff replacing the lead in lead replacement fuel is there more for the valves in four stroke car motors than anything else.Your valves are usually reed valves in basic 2 strokes I think and should be unaffected by the presence or not of the substite or even lead itself.The only other effect could be with regards to spark plug fouling and I would think you should notice no difference there either.Octane rating would give you your combustability so you should be fine in terms of performance too....Anybody have any other ideas???

You're on the money there Ajay, the lead or other metals are added to the fuel to protect the valves or more specifically the valve seats on 4 stroke engines.
The only spec thats important for 2 stroke would be the octane .

I dont know if thats such a good idea.On a car engine it would be a No No.I dont know that much about outboards but on unleaded engines some have a Lambda sensor and the off shoot off burning LRP fuel coats this platinum wire and ruins it.Rather hold on till some one more clued up responsds.Admit I could be totally wrong

Ajay is spot on. 2 Strokes are not fussy about petrol. My Yamaha 90's are now 15 year old  and initially ran on 93 leaded (when still staying in the old Transbvaal) and on 98 leaded when down on the coast. When I moved to the coast it was 98 leaded until unleaded became available and I started using that. Even now use leaded in Moz (when unleaded is not available) and even used a couple of cans of LRP a while ago when unleaded was very scarse here. All this different fuel was (is) used without any changes to the motors. I could also not see any changes on the spark plugs. A Yamaha dealer confirmed that unleaded is prefered, but the others will do no harm.  

No problems there - the leaded may give you a slightly better performance but hardly noticable - in Mozambique you use whatever you can get so my motors have seen it all !

AS everybody here has already said, it will make no difference on a 2 stroke. 4 stoke yes.

Hooked the main purpose of metal free fuel is to protect the catalytic converters used to minimise emissions. The platinum wire in the O2 sensor gets hot enough to burn most contaminants off.
The metals do however affect the catalyst in the converter.
