After seeing so many posts about how much oil to mix with Gasoline (Petrol).
I made up a couple of charts one for 25:1 and one for 32:1.

Gas to Oil Ratio Mixture Chart























EDIT: Oh the picture on the line with the 0.66 Gallons is the stock OIL Bottle that comes with our cars.

Edit: 16 November 2008 Corrected the 32:1 chart error pointed out by Brad.
Also corrected picture size (640×480) to forum rules.

When I look back at the container for the break in oil that came with my ss, it says {for a 25:1 ratio}, 1/2 gal.=80cc, meaning 1 gal.=160cc. He has it marked that 1/2 gal.=75.71cc, and 1 gal.=151.42cc. Who is right? All I know is that I'd rather be running with too much than too little oil.

100cc's of oil would work out to 37.854:1. You would be running very lean on OIL and will probably shorten the life of your engine.

Fuel (1) US GAL to Oil (100cc's or 3.381412796534052 Fluid oz) Ratio (37.854:1)

25:1 = 5.12 Fluid oz or 151.416cc's of Oil
32:1 = 4 Fluid oz or 118.29375cc's of Oil
37.854:1 = 3.381412796534052 Fluid oz or 100cc's of Oil


I think I got the math correct.....

This chart might explain it better (CLICKY)

thats what I thought when I took the 5T out of the box
But then again I am going to run Klotz 25:1 like i do in my boat.
I do believe that there is not enough oil there for a gallon though

Is 40:1 okay for the Baja?

The reason I ask this Is cause I use a pint of 2 stroke oil to make 40:1 for my 250R. I use 5 gallons of 93 octane.
