Fuel mixture

Recommended Posts

Hello could anyone tell me what fuel to 2 stroke oil mixture to run? Is 25ml of 2 stroke oil to 5 litre of normal unleaded right? As it seem very little oil.

Thanks

Yes, that's the amount I use. Runs sweet!

Thanks for the quick reply John.b I'll carry on and mix up.

That's the amount Nick said was recommended today when I asked at the demo day. It does seem low, but then you aren't lubricating the main bearings.

The Vertigo manual (http://www.vertigomotors.com/downloads/) says 0.75% fuel oil mix. That's about 133:1, which means 7.5mL per liter (37.5mL per 5L).

It would be cool if the resellers and the manufacturer could publish some agreed upon numbers...

Hang on a minute. 25ml for 5 litres is 5 ml for 1 litre which is 200:1. That's way off. Should be 60:1 ish

Not on a modern fuel injected bike it shouldn't ;)

To be fair the Beta manuals 'recommend' a much higher ratio than anyone actually run or I believe the Lampkin recommend, so this seems pretty standard!

I questioned this with Nick at VertigoUK, as there was a discrepancy between the 200:1 (25ml/5 litres) or 0.5% and the manual, which states 0.75% which works out at 133:1. Nick confirmed the 200:1 ratio as being the correct mixture.

Been running the Combat Camo at 25ml to 5 litres since August. No Problems. Convincing your self you have 25ml in the fuel is entertaining.

And it also shows that if the Vertigo happily runs at 200:1 what a waste of oil/money it is running  any of the later model watercooled bikes at more [oil] than 80:1.

No not at all, it's because the Vertigo is fuel injection, the main bearings are lubricated by the gearbox oil; whereas a normal two stroke they are lubricated by the mixture!
