The term "oilier" is indeed qualitative when comparing the special 2-stroke oil to conventional motor oil. But, when you include the mixture ratio in the definition it becomes quantitative. A 25:1 Hummer mix is twice as oily as a 50:1 weed whacker mix. And I agree with you, the Hummer mix will not hurt your other 2 cycle stuff, I run all mine the same way.

And, my habit has always been to add the oil to the can BEFORE I put the gas in it, dump 10 oz of oil in the can and head to the gas station to fill it up to the 2 gallon mark.


"Oilier" must be a qualitative technical term.

I have a 2 gallon gas can that I use for my Hummer, weed-wacker, chain-saw, etc. I mix it at 25:1 for the Hummer, although the other things specify 50:1. But the others seem to be happy running on the "oilier" mixture.

A story (I have a story for every occasion, but this one has a moral). I bought an Echo straight-shaft weed-wacker back in the early 1980's. It performed flawlessly until around 2005 (almost 25 years!), when it died a horrible death.

I would fill my 2 gallon gas can, and as soon as I got home, I would add the proper amount of oil. One day, I was in a hurry, and decided to add the oil "later". You can guess the rest of the story...

Don't let this happen to your Hummer. ALWAYS, ALWAYS, ALWAYS add the oil the minute you get home from the gas station!


original ratio was 5 ounces of 40 weight motor oil per gallon (1 part oil to 25 parts gas), so a 2 gallon can would get 10 oz. The Modern 2-stroke oil is a little "oilier" than standard motor oil, and modern 2-stroke stuff like a weed eater runs just fine on a 40 to 1 mix. Go with the original ratio, it smokes a little bit until the engine warms up good, but it will always get enough oil and you won't have to worry about it. Mike


Help the rookie please. If I have a 2 gallon gas can I want to use to fill up the motorcycle, how much two-cycle oil do I add to the gas can? Thanks
