Used to be it consisted of 1 oz of quickcare and 1 oz of quickleen per 5 gals. of fuel. I had come up with a system that worked well for me which consisted of 6 - 4 oz. bottles(purchased locally) into which I put 2 oz. of each(to treat 10 gals. of fuel). then stored on my boat. Then when I added fuel all I had to do was pour one of the bottle in followed by 10 gals. of fuel. The process was an evolution as well... At first I would measure 2 oz. of quickcare and pour it in the bottle. Then measure 2 oz. of quickleed and pour it in the bottle. Whole lotta measuring going on here. Well then the "dubhhh" moment arrived and I realized I could simply mix the 2 - 12 oz bottles into one container and proceed to fill the 6 - 4 oz. bottles... Looked something like this...
Mix these into that...
But with the addition of the 8.5 oz. of premium plus to the cocktail my lil 4 oz. bottles would no longer work.
What we're dealing with now, for 10 gallons of fuel, Is 2 oz. each quickcare/quickleen and 8.5 oz. of oil. or... 12.5 oz.
I considered purchasing some 12 oz. bottles on line or go looking locally for some. It was dang hard to find the 4 oz. bottles and I didn't really want to go through that again. Sooooo... remembering that I use the small Pepsi bottles when I'm in the boat so I checked those. Yup sure enough 12 oz. There is a space left when filled so I suspected they would handle 12.5 - 14 oz.s. Quick check with a measuring cup suggested totally full they'll hold approx. 13.5 oz. Perfect!
These are the bottles I use...
They're laid on the black cover to dry thoroughly after cleaning with water. After the water and to speed the process up I filled them 1/2 way with alcohol. Alcohol absorbs water and dries quicker than water. After rinsing with alcohol I blew them out with compressed air - if you do be sure you have a good inline drier or you can end up blowing more water back in the bottle. Then as depicted above laid'em out in the sun to ensure they were dry.
Before cleaning I did some checking and found out that 4 oz. just reached to bottom of the label and if I added 8.5 more oz. it came just to the where the bottle necks down where the cap it attached - perfect. So... every things clean dry and ready...
I take these... and mix'em...
In this... then shake them up to ensure a good mixing...
Now all I have to do is fill each bottle to the bottom of the label and I'll be ready to add the 8.5 oz. of oil.
Ok lil' snafu here... When I was putting the quickcare/quickleen in the bottles I came to realize PepsiCo. ain't exactly precise in the placement of their labels... But thankfully that's not the case with the shape of the bottle. Between 1/8" and 3/16" of where the bottle changes shapes(at the bottom) is the 4 oz. mark. Got all'a that sorted out and levels in the 6 bottles very similar. Let's face where not talking about brain surgery or giving children money A little less or a little more isn't going to impact the net results. I'm talking small fractions of an ounce, not quarts n' gallons
When completed they look like this...
On my boat I have a storage compartment that runs port to starboard across the back of the boat. I store these six bottle there for easy access when fueling.
The draw back to this new cocktail, for me, is that on the rarest of occasions I'd put in 15 gals. of fuel. It wasn't a problem adding treatment for 20 gals. A little over didn't hurt a thing. That is not the case now. Now I either have to put fuel in using multiples of 10 OR make multiple trips to the gas station over the course of a trip.
A word of caution!!! Once full and recapped out of a bright light these full bottles look a whole lot like a standard bottle of Pepsi. If you have children or partners with the brain of a child... Take the labels off or better yet use a different bottle. I originally thought the labels were going to be a measuring point but they ended up not being. So they're not necessary.
