We are all trying to find ways to improve our gas milage. So I know many have tried additives. I recently came across one that seems to improve highway milage. I happened on this at a recent garage sale. The guy had owned a fleet of delivery vans and had pruchased this stuff to help him with his fuel bill. He told me he tried a case and was saving almost $600 a week on his fleet of 25 vans so he then purchase "quite a few" cases. He had sold out his business and still had a few cases left so I thought for $3 a bottle, why not give it a try.

The additive is golden in color and uses 8ml / 10 gallons of fuel. The bottle is also a dispenser so it makes for easy measuring. There is enough a bottle to give a normal 15 gallon tank capacity about 10 tanks worth of treatment. I started out the tank before I left for SoCal.

I started out driving in a normal fashion, no hard accelerations, keeping my speed to posted speed limits and then after the first treated tankful noticed my average driving yielded an slight improvment from 18 mpg to 19 mpg for city/highway combined milage. Fill up and treatment to begin trip. Driving I-5 between Seattle and San Diego. I kept my speed to just above 60 miles per hour and on the first stretch I got around 22mpg, next tank I got 24 mpg. I let my daughter drive a flat stretch and she tends to drive a bit harder then her Dad LOL! She drove at around 65-70, harder accelerations and some mountains tossed in and got 20.5 mpg. On the flat drive on I-5 through central California, I kept my speed to 63 miles per hour and saw my milage go as high a 25.3 mpg on one tank. Mountains and LA traffic saw if shift downard again to the around 20-22.

On my trip back, I tried to do the same thing and this time I drove the entire trip, I ended up with some interesting numbers. I had consistant milage in the low to mid 20's, my best tank numbers being 26.2 mpg. Overall for the tirp the average tank milage was around 24.

Now I know many of you are going to be sceptical of my numbers but I will compile the figures for you a bit later, but it really did sem to do smoe good. Now while I paid a significant amount less for the additive then it sells for commercially, I think it may have helped save me some money on my trip. Everyone has to do their own investigation and trials. I was impressed but I don't think I'm going to rush out and buy a case of this stuff. It is called "eeFuel". Yes there are all sorts of articles both pro can con, but I would prefer to check it out yourself, on their website and google it for articles. It worked for me but like is stated in some of the articles, it doesn't work on all vehicles. Enjoy!

 

Educated people are skeptical of anything that does not make sense. A novel concept to you I bet.

 

I bet you do get a slight increase in fuel economy from them, however, If you add the cost of the additive to the price you already paid for fuel, and figure out the difference in mpg....I bet youll find it pretty much evens itself out.

 

I use the Lucas fuel treatment and it seems to help a bit. I know in my Lincoln I can run a lower grade fuel and it takes the valve rattle out. In the pickup it seems to be a bit more peppy (for a 22re). I seems to get an extra 40 miles out of a tank on the highway in the LS and about 20+- in the pickup, if I use it in every other tank. This is just my findings I'm not saying it's 100% accurate. But I know it helps the pinging fur sure.

 

Before you've convinced yourself that is has some effect, have you asked yourself just how or why it has an effect?

 

I agree with Team420, I've added Seafoam to my tank and got like 3 mpg more than average. The $$ that I paid for the additive was the same or more than the cost of gas to get me an extra 50 miles, so what's the point? I guess it means fewer stops on a long trip, but you gotta pee anyways right?

I wouldn't run additives constantly in my tank because Toyota designed it to run perfectly fine on gas alone. If your fuel economy is worse than it should be, then your engine needs attention and repairs.

If you're just trying to improve the normal, expected mpgs, most if not all fuel additives burn hotter than gas and that means more wear and tear to me - especially if you're running that stuff all the time.

 

the last time I used sea foam I smoked my 1st O2 sessor...
so I will stay away from additives for now

 

Just to clarify, we are talking about an additive that is used every time you fill up, correct?

Not like fuel system cleaner, Seafoam, BG44k, etc...?

I was stuck out in the middle of nowhere, with very low gas---my fault, stupid, stupid, stupid.

I got pretty far down in the tank. I was thinking about throwing some injector cleaner additive to my next tank, just to try and get rid of any of the crap, I potentially sent through my system.

Foolish? Folklore? Waist of time? Worth While?

 

i just put in a bottle of gumout in my tank when i filled up last week. i will do some calculations and see if i get any mpg gain out of it. i notice absolutely nothing as far as acceleration or performance goes. i average around 16-17mpg in my 93 pu. ill let you know what i get out of this tank, and if it made a diff. i primarily got it to get rid of any water that may have got in the tank from some after rain fun.

 

I'm not into adding something all the time and simply run a can of BG's 44k once a year or 12k miles and my cylinder top were pretty clean after 117k on my driven hard turbo Eclipse and my injectors ran a steady 92% to 100% (which they really aren't designed to do) over 8 years according to my datalogger.

I run a can once a year in my 4Runner and it runs just as good (and is a tad quicker to 60mph) as my mom's '99 Limited which has 60k miles less.

 

I think the Lucas Upper Cylender lubricant/injector cleaner works. I seem to get better MPG for the first 5 or so tank fulls after using it. It smooths out the idle a little as well.

 

ok so i just ran through my tank wit the fuel treatment. didnt do a damn thing. same gas milage as usual and no power difference. so its a waste of moneu in my opinion. maybe it cleaned up some deposits but who knows.
