    Fuel for a Sachs Motor

    I am reactivating my Sachs equipped bike. The book says to use SUPER petrol plus 5% 2 stroke oil.
    Now that SUPER is no longer available which of the UNLEADED fuels do I use?

    The octane rating of super changed a bit over the years - but this is a tiny 2-stroke motor, right? In which case standard unleaded should be fine.

    Lead was used as a valve seat lubricant. Your 2 stroke lacks valves, so the lead shouldn't be an issue. A high quality oil, mixed properly, and a high octane petrol (other than Shell brand) should be fine.

    Nope, all leaded petrol has now been phased out - we can get unleaded in 98/95/92 octane and Shell has a 100 octane which contains 10% ethanol.

    Shell also burns with a soft carbon. Not good for your 2 stroke, or vintage Jaguar.

    I thought you could still buy some sort of augmented unleaded that they called super.

    WTF you talkin' 'bout Expat? What is this soft carbon stuff?

    BTW, there's no such thing as a vintage Jag, they didn't exist until after 1930 - and the cutoff for vintage is Dec 1930 (unless you mean vintage in the popularly misused sense of car older than X years)

    You mean the augmented valve seat recession stuff? They've all dropped that blend now and it's all straight unleaded.

    Splain me about vintage wines then. Ok, instead of "Vintage Jag", how about old English cars you can't drive at night?

    Apaprently, Shell was at one time the fuel most likely to leave carbon deposits in your combustion chambers. All the more reason to rev that motor under load.

    Hey, I never need a reason to rev my motor.

    Hmm the carbon deposit thing is a newie, hubby and I both worked for Shell back in our mis-spent youth and I never recall hearing anything like that about the fuel. Was this in Oz or in the USA?
