Graduated oil-mixing measuring cup

I'm getting back into gas after 7 years away. Most of my workshop was lost in the Nashville flood of 2010, so I'm re-acquiring some of the tools and gadgets I used with gas engines before. One very useful tool was a clear plastic graduated cylinder (although not actually a cylinder, it was larger around at the top) with marks showing how much oil to add for various oil mixtures: 40:1, 50:1, etc. It had marks for both 1 and 2 gallons of gas. Very useful.

Does anyone know where something like this could be had? Or, what other tricks and tips do you have for easy, no-mess mixing?

thanks,
Rick

The cup is called ratio rite and can be had from a few places. I got mine from a local motorcycle store

The one listed above says it goes from 16:1 to 44:1. The one I found locally goes up to 70:1. I use 40:1 though.

Thanks for the info, I will definitely get one.

Here's a related question - sounds simple, but what gas cans are you using? I've done some looking online, and everything seems to have "safety caps" that reviewers universally complain about. I used to have a simple plastic can with a no-leak cap that I built a pump around. Are simple cans available anymore?

Jersey modeler cans look good, but expensive. Are they worth it?

I also have the hand crank fuel jug from Jersey Modeler. Works great. Right price for me. Well built.

I got one at a motorcycle shop several years ago... more of a cylinder with a cap, but it has markings for oil levels at different mix percentages. I got tired of trying to read the tiny letters and just made a mark at the 1 and 2 gallon levels for 50:1.

I have a Jersey Modeler fueler.... The motor and everything has worked great for years, but the O-rings that are supposed to seal where the fuel lines run through the lid are constantly cracking and splitting.. I have to replace them at least once a year.


The nice thing about the gas can is that it has a large opening on both sides of the top... so you have the fuel lines running in and out of one side, and the other side is open to remove and use at the gas pump. No leaks or anything from the lids, the motor has worked great, and I put a small 3-cell lipo in the electronics area... works for weeks on a single charge.

I only mix a half gallon at a time and at 48:1 mix ratio thats not allot of oil. I found the 50ml graduated epoxy mixing cups (from the LHS) work fantastic. 40ml of Redline to 1/2 gal (64oz) of AV100LL = 48:1. I also use a 1 gal graduated plastic paint mixing bucket (Lowes) to measure the fuel.

Its not critical to run a particular ratio, but having consistent batches of premix will help insure constant performance and reduce fine tuning.

+1 on the Jersey Modeler fuel cans.

So, you can use a metric measurement of oil with an Imperial measurement of gasoline? I thought that would throw the earth out of rotational alignment!!

You can go to Fastenal and pick-up a good quality 5 gallonBriggs & Stratton fuel can, PN5115819, for about $15.00 toss the cap andreplace it with a Briggs & Stratton gas cap, PN 796577, and you're set tobuild your fuel can.

This is what I use for fuel mixing:



... but I like the ratio-rite better so I'm going to order one of those. Thanks for the tip!
