Keno Posted November 23, 2017 Report Share Posted November 23, 2017 Seriously, be happy he even added oil, let alone too much. Lets do some math! So, 20:1 means 20 parts gasoline to 1 part oil, 20+1=21 total parts. 40:1 means 40 parts gasoline to 1 parts oil, 40+1= 41 total parts. Take 1/41 to get 2.44% oil and 1/21 to get 4.76% oil. So 4.76%-2.44%=2.32%. So he added 2.32% too much oil. This effectively leaned your jetting by 2.32% due to the displacement of the fuel by the oil. I very much doubt a 2.32% change in your jetting is going to do anything unless your jetting was very lean to begin with. Edit: "So he added 2.32% too much oil" is incorrect. He added 100% too much oil. It should have said, "The fuel contained 2.32% too much oil" Quote Link to comment Share on other sites More sharing options...

He used 32 oz instead of 16 oz to the same amount of fuel. His Motor will be fine but your math needs some serious help. Lol!

Sent from my iPhone using Tapatalk 32/(640+32)=0.0476 16/(640+16)=0.0244 0.0476-0.0244=0.0232 Maybe I am doing something wrong. Please correct me. Edit: I just realized that my math only works if you ADD the oil to 5 gallons of fuel. ie Final volume equals 5 gallons plus the amount of oil added If you put your oil in the jug first then add fuel to the 5 gallon line ( final volume being 5 gallons (640 oz) including the oil) then you are making a 5% (19:1 or 608 oz fuel to 32oz oil ) and a 2.5% (39:1 or 624 oz fuel to 16 oz oil) solution. Then he would have only added 2.5% too much oil. v/v%=(volume solute/(volume solvent+volume solute))x100% so (oil/(gas+oil))x100% = volume% oil Quote Link to comment Share on other sites More sharing options...
