Octane Level

What is the correct level of octane for use with 50cc mopeds?

Thanks

87 Octane.

Octane doesn't really matter tho, and skip the additives, most of em won't do jack for a two stroke and might even gum it up....a teaspoon of gas treatment every great once-in-a-while won't do it no harm, tho.

Ever 2cycle motorized two wheeled vehicle i have runs better on high octane. Try to skip the Ethanol(veggie shit) its not very good on them also techron helps.its gas treatment that chevron uses. it works wonders.

I beg to differ on that.

Depending on your plug, the lower burn temp of a higher octane may not fully vaporize the gas/oil mixture, resulting in an increase in carbon and fouling issues.

But hey, go with what works for you....mopeds are as individual as their owners.

Thats what the Techron is there for, to help clean the plugs and cylinder.

Re: Octane Level

Of course, if you have done certain performance mods such as shave the cylinder head or run a thinner head gasket, or have advanced the timing, a higher octane fuel might provide a little insurance against detonation/preignition. (Especially in hotter climates.) Otherwise, regular gas is fine.
