Does anyone have a 33:1 oil ratio chart they can put up.I did a search and found nothing.

Aussie, why do you need a chart?? Simple High school mathematics! some of those things you learnt were actually helpfull.

33ltr fuel to 1 litre of oil.

Divide 1000 (1ltr = 1000ml) by 33 -> 30.3ml of oil

therefore for every 1 ltr of fuel add 30.3ml of oil

eg 5ltr fuel -> 5x30.3ml of oil -> 151.5ml of oil

you can tell me off for being sarcastic!!! ^rof

I don't think mixing oil is really an exact scient... as muchkin said - 30ml per litre or anything close is good enough.... if you've got a 10 litre tank, you know it's close to 300ml's. If you rememebr that then when you half fill it.. .only put in about half that amount. Anywhere from 25 to 50:1 and the bike will run fine i'm sure... provided it's a high qual oil. You'd be surpised how far your motor would get you if you only ran 100:1 :p

It's actually for another guy who wants a chart to stick in his bumbag I have a DRZ so no need for this stuff but just thought you 2stroke boys would have one to print off nice and easy.

Thats Charlie your a Gem thats exactly what I wanted

Ian,

Go to any shop that sells Motul, they usually have business cards that have the chart on them....

Most bike shops have a Motul card (business card size) that shows a heap of mixture ratios..........but if you want to mix something odd like 3/5/8 litres etc you still need to use your scone. :)

I printed the mixing chart on the back of my bussines cards I can send you a few if you like.

This chart may help if you want to refine/tune your 2stroke via the pre-mix ratio. More oil makes fuel lean, less oil makes fuel rich. PS tell this to your mates to start an argument over lean and rich jetting!

Acutually your oil ratio will effect the fuel/air ratio, more oil means less fuel per part for a lean ratio and less oil equals a richer ratio, so it is always best to jet for a certain fuel/oil ratio and to stick to it.

Try this out.

1/32(oil) X Fuel(Lts)= lts oil to fuel.
Eg
1/32 X 10= 0.03125X10=0.3125 lts or 312.5 mls.
Transpose this for fuel
==>> if you have 3 lts of fuel you would need at 32:1
1x fuel/1x32==>> cancel out the ones you get fuel/ratio oil = oil to add
eg (1x3)/(1x32) ==>> 3/32=0.0937 or 94 mls

You don't need a graph, just a calculator.
Try it, it does works. And stops making critical errors in oil ratios which could speel seizer for your motor
