Oil to fuel ratio
« on: September 06, 2017, 03:11:39 AM »
Normally I ignore technical questions sent through email, but I enjoy numbers, so here's an email I received:

I HAVE 15 gallons of 35:1 from my old new engine is many gallons of fuel do i need to get the 15 gallons all up to 50:1?

If you have 15 gallons of fuel mixed 35:1, than that means there is

15*128/35 = 54.857 ounces of 2 stroke oil added to the fuel. Will represent the gallons of fuel you need to mix with 54.857 ounces of oil to get a 50:1 ratio by the letter x. So,

x * 128/ 50 = 54.857, x= (50*54.857)/128, which makes x equal to 21.4 gallons. 21.4 gallons minus 15 gallons is 6.4 gallons. So you need to add 6.4 gallons of fuel to your mixed 15 gallons of 35:1 fuel to change the oil to fuel ration to 50:1
Im tired so double check everything. I'm not responsible for mistakes......
