    Ever since I bought my motorized bike, I 've relied upon guessing the right amount of oil to put into a fuel mixture. Or if I bought the right oil container, I would have used the measured markings on the side of the bottle. After some looking, I found this: Amazon.com: RATIO RITE CUP - Kam-Tech -: Automotive.

    The Ratio Rite measuring cup has markings for ratios from 16:1 to 70:1. Markings for 1, 1.5, 2, and 2.5 gallons. Since buying this, I'm sure that I'm mixing the right ratio of oil to gasoline.

    For lawn equipment I use to use the premix measured packages of 2 cycle oil and it was for 2 gallons so I always used a 2 gallon can and there was never no guessing, maybe thats not the right ratio for a happy times buy its idiot proof if it is.

    I believe the MixMizer is best for small batches (like for a metal fuel tank on our bikes). What I like about the Ratio Rite cup is that it has a cover to keep dirt out and it has plastic notches indicating ratios for four different batch sizes. The mixing cup is useful for making gallon size batches; this is especially good for making lawn equipment batches quickly for premix containers.

    Ratio Rite is good for general use.

    It comes with a cover? Nice. Maybe we should carry that one as well!

    You should. The ratio increments are as follows:

    8:1, 10:1, 12:1, 14:1, 16:1, 20:1, 24:1, 28:1, 32:1, 36:1, 40:1, 44:1, 50:1, 60:1, 70:1


    One side of the cup has ratio markings, the other side has standard measurments markings. The measuremens are in pints , cubic centimeters, and fluid ounces.

    The only downside is that, due to the fact that the diameter increases from the bottom-up, there is left over residual oil that pools on the bottom of the container after settling. This amount is negligible compared to the amount of oil that is poured.
