# Help with some gas mixture math, please!

For all the guys saying to get 32:1 in metric you simply multiply by 32... Technically that gives you 31:1 FYI

Okay, so Im helping a friend mix 32:1 gas. I mix this a lot for my bike, and I know its 16 OZ of oil per 4 gallons of gas. I'm trying to figure out what that number would be per 1 gallon. Some math says if you divide that in half, it would be 8 oz oil per 2 gal gas. Divide that and you get 4 oz oil per 1 gal of gas. Can someone just verify this number real quick? Thanks.

Dude,,,,, Like, if an ounce of sinsee makes 16 doobies, how many doobies in a quarter?????   Ha!  What was the question?

west marine has a container like this

better than the ratio write cup because even  with  the optional lid the RR cup drips  and my last 3 RR cups cracked

this style also has better mix ratios marked

Wow lot easier in the uk

32ml to 1 litre of fuel.

Wrong, 32:1 in metric is actually 31.25ML per litre, close, but flawed. 40:1 is 25ml per litre, because 1000/40 is 25. It's by pure coincidence that 32:1 is very close to 32ml per litre.

Just X 32 by how many litres u have and BOOM!!

The easiest way to figure out how many ounces for your mixture of 32:1 is to divide the ounces of fuel by the 32.  That's how many ounces of oil you need.

32:1--128/32 = 4 ounces

50:1--128/50 = 2.56 ounces, or just 2.5

You've done the matt correctly.. honestly I don't see the point in running fuel at 32:1 ratio, which also requires richer jetting than normal, which may gunk up your power valves with carbon deposits and clog up your silencer packing.  But you got the math right buddy.

And BTW I don't mix my fuel exactly like some guys do.  I just look at the oil level on the side of a quart bottle, and guestimate about how much needs to be mixed for 2.5 oz per gallon, 50:1 ratio.  Any error is negligible.
