A common glass Pyrex measuring cup available at the grocery store hosewares section will do the job. It is marked in both ounces and ML.

Referring to the original post:

One of the reasons your car may have been detonating is that ethanol mixtures tend to run leaner than straight gas. Ethanol mixes require a larger volume of fuel to maintain the same AFR. you can tune for ethanol if it's something you're going to use on a regular basis. If your injectors are on the ragged edge now, it may mean the need for stepping up to the next larger injector to get the fuel volume required.

Ethanol mixtures end up costing the consumer more money. Less bang for the buck than standard gasoline because more is required to produce the same power.

That makes sense Daggar, but I don't think my injectors are by any means maxed out. This is on my daily driver which is a 2003 Lexus IS300. They run a little rich from the factory, but I have also added headers and a CAI to it which may have compensated a bit for the richness. I have a piggy back fuel computer I need to install to do some fine tuning with the fuel along with a 75 shot I got for it a while back, but I haven't had the time to install . These cars typically don't need larger injetors unless you go over a 100 shot or add boost. Thanks for the input though. I learned something new about ethanol.

yea, as long as its says that it's 100% pure acetone, then that will work. Acetone is the main ingredient in paint thinner. It won't damage any of your seals or anything. The rubber fuel components are made to withstand gasoline, so 3 oz. of acetone in 10 gallons of gas won't harm anything at all.

I always thought it was 15.6? Maybe I was mistaken?

If it says "acetone" on the can and not "paint thinnner or mineral spirits" then it's most likey 100%.
