An Effective, and Affordable Alternative to Lucas UCL / Fuel Treatment

OK, moving on...
Although I am a fan of occasional use of Techron fuel system cleaner, I am generally not a fan of the usual fuel additives on a regular basis. This is my one exception, I have used it in both my vehicles for years, I use it every time I get gas. While I will not make any wild claims about using this product, I will share my experience, and share that thousands of other people have used it with similar success.
* Slight increase in fuel economy / miles per gallon. In my old van, I consistently see 2-4% better fuel economy. 27mpg Highway, with almost a quarter million miles.
* It more than pays for itself, via the increase in fuel economy.
* Provides a bit of lubrication and protection to the fuel pump, fuel lines, and injectors.
* Helps keep the fuel pump, fuel lines, and injectors clean.
* Quiets down the fuel pump, and injectors a bit.
* Helps keep the top end/valves a bit cleaner.
What is it?
* TC-W3 Outboard 2-Stroke Oil. About 1 ounce per every 5 gallons of gas.
For some of you reading, this may sound a bit crazy, and not only are you entitled to your opinion, I'll say I thought the same when I was first presented with this idea.
Results are varied in different motors, and with different gas. I have the 3.0L in my van, and I always run Non-Ethanol gas.
The fuel efficiency increase is not a placebo effect (not in mine). I have done a few fillups without along the way to see if there was a drop, and there always is. The gain in mine is around 2-4% more miles per gallon.
There are different brands of the TC-W3 oil around, Pennzoil is popular. I buy the plain old SuperTech TC-W3 by the gallon at WalMart, it's 12 dollars and change a gallon. They also sell it in a pint bottle for 2 dollars and change, which is a great size to buy and try it out, and also makes for a great measurement bottle (has the oz markings in the clear view up the side of bottle), and one to stash in the van and use for fill-ups.
A gallon will last for well over 10,000 miles, give or take depending on where you drive city/hwy.
The only thing to make sure of is the TC-W3 rating, that rating is for the water-cooled outboard engines, and it will burn off completely and cleanly during combustion in a 4-stroke engine.
I will again state my disclaimer.. I'm using 1 ounce per every 5 gallons of gas. Thats 4 ounces in a 20 gallon tank. If you stop and get a few gallons and pour a whole pint in your tank, please don't be mad at me when you're spraying for mosquitos for the next couple hundred miles There is no smoke in the exhaust at the rate I'm using it. And while I can't say it keeps the valves and top of piston shiny new, or makes everything last forever, I CAN say it offers me an increase in fuel efficiency, a quieter fuel pump, quieter injectors, and the hope that those components are all a bit better protected. I have heard from others that use it say it makes their engine idle smoother; I did not experience that myself, but my van idled pretty smooth to begin with.
I also use it in my motorcycle, although in it I use a bit more - 1 ounce per 4 gallons of gas. I can say verifiably in my bike, it keeps the insides of the carbeurators squeaky shiny clean, and the idle is noticeably smoother. I do not keep track of my fuel efficiency on her, as it largely depends on how spirited my driving is during a given tank.
This trick is also used in diesel fuel, and its been around for a few decades now. It will not harm any sensors or anything else at the ratio used. Please do look into this if you are interested, there are many many writeups to be found of success stories with use, and if anyone gives it a try, please do post your results in the thread here for others.
