I've never used it myself, but in the may 1998 issue of Drag Racing Monthly, David Vizard recommends a product called TK7. He explains that the TK7 is a fuel additive that, when burned, becomes an upper cylinder lubricant. He says this stuff is sold in bulk to poor countries to offset poor fuel quality. It's supposed to reduce emissions and prolong engine life. Like I said, I have not tried it yet, but plan on getting some soon to see if I notice any difference.

Ever since I've owned my '88 Escort I've used a quart of Slick 50 or simular product in it every 50K miles and it currently has 486K miles on the original engine with no engine related problems. I use it in all my cars. I've been using FP+ and LC-20 for about the last 6 months or so in it too, but I haven't noticed any improvement in FE. I can tell that the LC-20 is slowly cleaning deposits off of the rocker arms just by looking through the oil fill cap.

Ford Man, no disrespect, but you understand that your experience with Slick 50 proves nothing, right?

It would be relatively easy to find high mileage examples that never used any additives.

There are worthwhile additives. A bit of biodiesel in ULSD is a perfect example, keeps all the FI system happy and well lubricated. Injector cleaners can help get rid of the accumulated carbon. I only believe additives can help restore FE, not increase it. The only exception I know of is oil additives containing PFTE, but that's harmful to engine longevity in the long term.

I have done a lengthy test of using Marine Spec TC-3 2 cycle oil. Mixed at 1 oz/5 gallon. There is a big thread on it here:

Been testing - LS1 Performance Information

My results on fuel economy are inconclusive due to the climate change as I got into my fourth and fifth tank. However, my escort idles noticably smoother. Fuel pump is a lot quieter. And it is definitely easier starting. It is basically billed as a top end lubricant and fuel system/top end cleaner.

I've been using it in my fourwheeler, and it is SO much easier to start now compared to what it was. Now it will start after about 3 or 4 turn overs, compared 7 or 9 before. It was getting to be a bear to start in cold weather.

I need to break down the data in fuel logs and see if I see any trends in there for sure. Just glancing at them again, it appears there may be a decent increase in mileage trend. I wasn't using it for mpg, but for top end cleaning/lubrication.

I understand that it PROVES nothing, but I can say in 33+ years of driving and 14 vehicles I've never had an engine last like this one has and still uses less oil than lots have after less than 100K miles. I certainly don't think it's hurting anything and buying a brand simular to Slick 50 at approximately $5. per quart and only adding it every 50,000 miles it's only costing 1/10,000 of a cent per mile. I used it in a moped once and the average mpg went from about 100 MPG to between 105-110 MPG. I don't remember the exact numbers, but I think the mileage increase about 7-8 MPG.

Ashless 2-cycle oil is also frequently used as a lubricity additives in diesels. Biodiesel have better lubricity though. I Never thought about putting 2-cycle oil in gas though. If you can do it with 2-cycle oil, any reason not to try biodiesel instead?

Hey guys, I've been a member for a while but this is my first response to a post. When i saw that someone was looking for a fuel additive and that people were actually recomending seafoam I have to chime in. I've come across a fuel additive that's environmentally friendly (not petroleum based) and IT REALLY WORKS. I've done a side by side test tube comparison with this stuff and Gummout, STP, BG, Seafoam, Mopar's factory pour in, you name I've tried it. It's called ECORITE fuel system cleaner and you'll have to get it at a Toyota dealer. I know the Southeast Toyota dealers have it readily available, not sure about the rest of the Toyota districts. ALL of the additives I've tried and the Mopar was the worst, did absolutely nothing to treat water in the fuel system and they ADDED just as much soot and carbon to the engine as they got rid of. If you guys could have seen the tests and results I'd seen, you'd never look on a walmart shelf again

I use acetone in small amounts 1-3 oz per 10 gallons of gas. It's cheap in bulk and does increase MPG. Another thing it is in expensive fuel additives. I have read the patents granted for it's use in improving fuel MPG as an additive. Just search patents gasoline acetone mpg, or patent gasoline additive acetone, anyway that's how I discovered it when I looked at hundreds of other gas saving systems patents. There is like over 400 gas saving patents. Acetone cleaned my fuel tank and I had to change the clogged fuel filter soon after I started using it. But in the small amounts no problems, I have been running it a year.
