Pre-mix made easy
 

Hi guys, I just purchased my first RX-7 and I'm absolutely loving it. Having said that, my first experience with pre-mixing at the gas station was clumsy at best and very frustrating.

The prior owner had about a quart of Castor in the rear bin (in a 2 quart jug), in a plastic zip lock bag with some rags and small measuring cup that maxed at 4 fluid ounces. Pouring out of the large 2 quart container, into the small glass and then into the tank was going to be a messy proposition. So, I ran inside the gas station and bought the smallest funnel they had. Problem is, our fuel doors and gas receptacles are minuscule and even the smallest was too big.

To make a long story short, it was messy and was something I never wanted to experience again. I wanted to keep things simple. I wanted it to be easy and without any need for cleaning up.

Alas, I decided I'd use a gas treatment bottle from the local autoparts store to pre-fill at my house and store in my bins and use as needed. I settled on an STP gas treatment bottle that was 12 fl oz. in capacity and only a few bucks per. I bought two, you can buy as many as necessary. This is what the bottle looks like:

The beauty is that this bottle was designed to fit in a fuel filler. You needn't use a funnel and because it's all pre-packaged and self contained, there's absolutely no cleanup. I now keep two bottles with 12 fl oz. of pre-mix in my rear bin and simply pour the entire contents of the bottle before I fill up and pump 12 gallons of 93 octane to stir it up (I don't have an OMP).

Always keep wet naps, or hand towels or whatever you prefer in the bin as well, in the case you get a little oily residue on your hands or the bottles. We wouldn't want to oil up our beautiful cars would we?

Anyways, I hope this helps, I'm certain I'm not the first person to have this idea, but after searching the boards, I didn't see anyone doing this. I did see one 2nd gen'er doing something similar but only at 3 oz. per bottle, which to me is not realistic. Our tanks are rather large and emptying 4 or 5 bottles of pre-mix before fill-up is kind of annoying. With this method, it's simple, it's easy and just one bottle per tank, filling up with 12 gallons (which leaves me just under the F from just under the 1/4 tank mark).

Feel free to try another setup which is better suited to your needs. I chose this bottle because of it's larger size and it's cost (only about $3 per) where some bottles of gas treatment were $8 and $10 per bottle. I didn't want to spend that money for just a container, when I would be pouring out the contents into my oil receptacle at home anyway.

Hope this helps!

I do a similar thing, except I use 2 of those Lucas fuel treatment bottles, they are 5 oz each, which is good for up to 20 liters each, that way if I am going out of town and have half a tank, I can top it up with 20 liters and use only one, or put both bottles in for a fill up of up to 40 liters. I think the B2200 fuel tank is smaller than the RX7 ones, or I just fill up with more fuel in my tank.

Good idea! When I was looking for something to make mine less of a mess, I grabbed 2 of the bottles used for refilling R/C cars from ebay for about $4/each. It has a long spout with a cap on it and holds about 17oz. I just leave 2 of them prefilled in my rear bin along with some rags in a ziplock bag. It's worked well so far, but I'm only about a month in.

I use oil quarts, they have the oz lines on the side, so half a bottle per full tank of gas. I use a thin and long flat head screwdriver to hold the trap door open while I pour the oil down the gas tank. Once completed, I use on of the paper towels provided at the gas station to clean the screw driver, and the bottle.

You don't feel odd when people look at you shoving a screwdriver into your gas filler neck? lol

Give it a shot man. Planning ahead and filling these up makes the whole procedure much easier and cleaner. Only takes a minute to fill them up at home and saves you cleanup time at the pump...

Whatever works for ya though :):icon_tup:

No issues here. I just use the graduations on the side of the premix bottle.

I just use a clear plastic 4 oz. bottle with a screw on lid.
No need to push down the fuel filler neck door, the oil will go in.

We use these washer solvent bottles at my dealership. I save up boxes and boxes of them, clean them out, fill with oil, and keep some in the car. And trash them afterwards!!

The screw driver is not what gets me the looks, its the damn oil container getting poured down :lol:

I don't plan ahead, I buy quarts of 2 stroke oil at walmart. The long thin screwdrivers is always in the car. I keep the quarts and screw driver behind the drivers seat, 6-8 quarts in a row.

The screw driver is not necessary, but it speed things up.

Why not just keep re-using them?
Saves a lot of steps, no? :nod:

I just use a quart oil bottle. who cares is someone "looks" at you. give me a break

Funny, i do the same thing, except i use a gun cleaning rod. :lol::lol::lol::lol::lol:

The true benefit is how simple and hassle free it is because you have exactly the right amount of oil and there's less potential for a mess. I didn't think of this because of how it looked. But, the image of someone shoving a screw driver into their tank is kind of funny and would make me scratch my head a bit... :scratch:

I no more premix at a gas station. But in the garage just before heading to the nearest gas station. More relaxed experience

in PR people look at me funny if I don't premix at the gas station!

:lol::lol::lol: That's funny! :icon_tup:

I use redline 2 stroke racing oil, comes in a ready use graduated bottle. No need for a funnel or any other tools

I refill the 2 stroke squeeze bottles made by Echo.
1 oz per gallon.

This looks very expensive... Few times more than e.g. Idemitsu premix?

I did keep them at first, but as the stockpile grew, It didn't matter much anymore. The only steps I do are rinse them out with water, then throw the cap and bottle in a box to dry out. Later I fill a bunch with oil at the same time. Also, they seem to hold up to the oil just fine, but I'm not sure about long term.

just squeeze it till its filled (twice) shove the funnel in and dump it in.

and I could care less how people look at me while doing it, they already look at me weird seeing a 300 pound 6 foot 2 guy getting out've the small thing!

Puerto Rican ingenuity, I do exactly the same, LOL.

Damn, that's a lot! I'll pay you some shipping if you don't mind sending me some haha.

A regular 2-stroke quart bottle with marks on the side is all you need. No funnel, screwdriver, long neck bottle or anything is required to push in the flapper the oil goes in just fine.

you dont really need to hold the flapper open , even if you use a quart bottle (which I use) it will go down into the tank maybe not as fast as if you had it open but it makes life alot easier I think ..
