Moto Guzzi Robin oil mix ratio?

Fixing up this bike for a friend and the online manual says 4% ratio of oil to gas. Never seen it referenced in that way.

So if there are 128 oz per gallon of gas X 4% = 5.1 oz of oil. Seems quit rich.

Anyone have another source or is this right?

50:1 or 40:1 mix is fine. I use about 3.5 ounces oil per gallon.

I used to use 4% in the Moto boat Kane and that was about 4 oz to mid-grade to a gallon of mid-grade instead of regular

Re: Moto Guzzi Robin oil mix ratio?

another way to think of it is 4% is four per cent (100) that is... 4:100, or in other words 25:1. The story is oil just used to be shittier. you're totally fina at 50:1. even better off usually, less likely to foul with less oil but no more likely to seize.

run 50:1 (= 2%)

That was the answer I was thinking.

Fits with what Lar was saying.

Many thanks
