I am using the Tanaka Perfect Mix oil at a 50:1 ratio as recommended and it works great. On the Tanaka website, in their FAQ section, I found that the gas to oil ratio should be what the oil manufacturer has listed, and not what the manufacturer of the engine has listed. A part of one of the answers has "there are 16:1, 25:1, 32:1, 40:1 42:1, 50:1, etc. However, if you analyzed these oils, you'd find very similar amounts of the actual ingredients needed to provide the life allowing lubricity (even at these odd ratios)." This means if you take 50:1 oil and mix it at 40:1 there will be too much oil in the mix, so we need to make sure we are mixing the oil and gas as the oil manufacturer lists.

If you are using these bottles with a one gallon gas can you will need to measure the oil, which makes it a little harder to use. I have a 100 ml graduated cylinder and measure 76 ml of oil, which is 2.6 oz. This is then mixed with one gallon of gasoline for a 50:1 ratio.

The bottle size is just right. Mixed with 2 gallons of Premium fuel my equip,emt runs great.....Actually Much better than before.....

I bought this oil because it was a good price. After using it I pulled the spark plug. It burns clean and doesn't smoke

I had an Amazon Gift Card and did not want to buy this product locally because the price was full retail plus sales tax, so I ordered 2 of these items and got free shipping and no sales tax. That is what I call a Win-Win situation. It runs great in my PF-4000 Tanaka engine.

1 bottle isn't sufficient to 1 gallon of gas... have to use ~ 1 1/3 bottles.. there others out there that are more conveniently sized. Other than that, after some careful measuring, it mixed in and my weedeater runs fine.
