Can't really say since I do not know the amount of oil in each individual package, but it the label says to add entire contents to one gal of gas for a 50:1 mix....(label usually states if its a 50, or 40:1 mix) then you wuld just double the amount of gas or reduce the amount of oil by 1/2.......Originally posted by farmallmaniac
so how much oil would you mix in with 6 gallons of gas for 100:1

The link below might be worth a look. I’m no expert on fuel mixtures, nor do I know what you are mixing gas for, however, be sure that 100/1 is enough oil. I’ve been told that some outboard boat motor manufactures called for 100/1 after break-in but after having problems sent out an advisory to keep the mixture at 50/1.
In playing around with the link you’ll find that for a 100/l mixture you would need 1.28 oz. of oil for a gal of gas. I’ve always been told that in mixing oil and gas a little too much oil is better than not enough. So, if you don’t have a way to measure exact decimal amounts in figuring your oil amounts it is better to round up to the closest value you can measure.
Hope this helps.
Something just does not seem right with that calculator, as "ALL" oils are blended different and all manufacturers have different amounts of oil to add to get the so called ratio oil. So using that calculator you could actually have a 50:1 mix but it could stil be on the lean side or rich side depending on the oil used. Using that calculator, if I was to have bought all my oils in say a one gal container, and used it to mix up a batch of fuel, the oils I listed would all give an ultra rich mix. Using the ratio on the bottle it would take 6.12 oz of oil but more than double that amount if I used that calculator
