I just tried it in my 2002 Toyota Tacoma at the last fill-up for the first time after reading about people getting better fuel economy. I used the 4oz/10 gal fuel recommended dosage. My fuel economy went from around 19mpg to 16.5mpg. Hmmmmm. I am going to run it through one more time and see if it stays low. Then I'll quit using it for a few fill-ups and see if mpg goes back up. We shall see.

FWIW, I keep some in a spray bottle and use it as a general lubricant around the house. Works well.


Try lowering the dose a bit too.
 
I wouldn't dream of putting gas in my Jeep without it, I gain over 2 mpg when used consistently plus I'm getting the cleaning and lubricating benefits as well.

My son uses it consistently in his HM Chrysler and gets about a 1 mpg boost, the cleaning benefits are desirable for his high miler also.

We have two Chevy's that could care less whether I use it or not, so I don't.

I have ONE question...what does your owners manual say about using things like this? If your car is under warranty I bet it says DO NOT USE unapproved additives.

Yeah, but I'm sure the dealership will sell you a $69.95 injector cleaning service during a 30k mile service. I'd like to see them deny a warranty issue b/c of MMO use.
 
to:demarpaint yes you are right . i put 2 oz in tank on fill up, i fill at 1/2 tank, that will go through the injectors and 1 qt from oiler in 800-900 miles.

The oiler mix you have along with 2 oz to a half tank of gas is a bit too much, especially if you have a small displacement engine. Try dialing in the oiler to 1 qt/1000 miles which is the suggested amount, without any in the gas. [At least it was back in the 1980's when I bought mine]. Or 1 qt/1200-1500 if you plan on adding 2 ounces/10 gallons of gas. You might have to tweak it some. Too much MMO will lower mpg.

If it has a site glass like the original MMO units did, count drips per minute while the engine is idling hot. You want about 8-10 drips per minute. Drive 500 miles and measure how much MMO you used, it takes a little while to dial them in.

That "injector cleaning service" probably a BG product... has APPROVED detergents in it...not to mention that rarely do any dealers offer this type of service DURING the warranty period. Most likely it will be offered after the warranty is up.

Detergents are the most effective cleaning element in fuel and any fuel system cleaner...MMO is not proven to improve performance or effectively clean..ANYTHING...I say "show me the certified independent tests" that confirm it.

I'll be waiting .......a loooooong time...

In the meantime I hope folks here with a newer car under warranty will stop and reconsider using things like MMO.

Sure the car maker may not deny warranty coverage...BUT they might...you never know. If the owner's manual specifically states NOT to use UNapproved additives in your fuel system they could easily deny coverage. That is a fact.

Can they test fuel to see if 4 ounces of MMO was added to 10 gallons of gas? Would they spend the money needed to get accurate enough results? Even then gas blends vary enough that a 400:1 mix of MMO to gas would be tough to detect. They won't know unless you tell them. I bet there are things in the fuel a lot worse than MMO, TCW3, or any fuel injector cleaner. These things sit inside the fuel tank at the gas station in the ground waiting to be pumped. I bet if you had fuel problems relating to dirt or water they'd ask where you gassed up, they might even suggest you recover damages from the gas station.

Detecting it added to oil would be easy enough, the gas I highly doubt it.
 
George, I dont see any problem adding it to older carb'd cars/vehicles and farm and heavy duty stuff honestly that need a good fuel source, since the fuel is unleaded these days and off road diesel isnt cheap.

+10...I doubt very seriously anyone at a dealership service department would be able to tell if you added MMO or any other additive to your gas. They have much bigger fish to fry and would much rather spend their time on customer-pay and warranty repairs that will bring money in to the service department than try to accuse a vehicle owner of adding additives to their fuel, let alone spend the time, effort and money it would take to try to prove an owner added any additives to the fuel or oil and then to try to prove the additive caused any specific problem. A good tech being paid on flat rate would much rather do a customer pay repair that puts good money in his pocket than spend two hours chasing his tail and trying to analyze a tank of gas that might be reported to have 6 ounces of a fuel additive in it...Either that or the service manager or writer might hand the "gas tank additive inspection/diagnosis" job to an hourly-paid rookie tech apprentice to give him some work to do, but he won't know what to look for and would not find anything anyway. And as soon as he gets started on it, they will tell him to button it up, get it out of the shop and move on to the customer-pay oil change/tire rotation job that just walked in.

Dealers don't care, service writers don't care, techs don't care, nobody at a dealership service department really cares if you added MMO so why bother even mentioning it to anyone at the dealer? Even if you did mention it to a service writer his response would most likely be something along the lines of "So? Our BG fuel additive is better, you should have had that done instead." Technician and service manager would likely say the same thing, if they responded at all. Translation? They don't care about MMO, they would rather sell and perform a BG fuel system flush for $129.95, and the reason is very simple: They make a boatload of money off of the BG, Everwear, 3M or whatever fuel system service they sell at the dealer! And no dealer service writer in his right mind is going to refuse the revenue from a BG fuel treatment just because the vehicle is still in warranty. They will do the service and gladly take a customer's money for it any day of the week.

Not trying to be a know it all or disrespect anyone here, but I have been there and done that, seen it myself. In 2005 I spent a very long hot spring and summer working as the hourly-paid rookie apprentice technician at a Chrysler-Jeep dealer in Tampa. I learned more than enough about dealership service practices and methodology to teach me to stay the heck away from dealers, no matter what. There might be some good dealers out there and I guess while the vehicle is in warranty you have to use the dealer but I don't trust car dealers any further than I can throw a cheesecake underwater. That goes for the sales floor, F&I guy, sales manager and owner/General Manager types too.

Rant is over. No dealer will waste his time trying to identify MMO use in a fuel tank or oil sump. MMO is a good product, OP and anyone else can try it and see how it works in their vehicle.

The dealer might not ...BUT the manufacturer might..and in the end if you are found to have VIOLATED the terms of the warranty you might be DENIED coverage. This happens, more than you think, I've worked at many different dealers and THEY DO test for this if the cost of the repair is large. Don't be surprised . You've been warned.

Hey, if your warranty coverage is done, go right ahead, but if you are relying on that warranty, think twice.
 
^Well, can they tell if MMO was in the gas or fuel if it's already rinsed out? Just don't have it in the oil during work at the dealer.
 
I'm actually experimenting with 3 oz. in my 13.2 gallon tank in the Corolla. Just completed the first run and on my second tank. We'll see. Check my signature for data so far.
 
I will say this much..Before I started using MMO I did a ton of research both here on BITOG and other internet forums. I still read up and research MMO because I like to read about how it performs for other people too. In all the time I have been using MMO and reading about it online I have yet to come across a single post or internet article that said MMO damaged an engine or fuel system or caused any internal problems with an engine or fuel system. I have read posts where some people said MMO did nothing at all for them, and I read a few posts that said they lost MPG when they tried MMO. I suspect in both of those scenarios the vehicle owner probably overdosed or underdosed the MMO, or maybe they did not use it consistently or for a long enough period of time to see any benefits from it.

The warranty on my truck expired long ago. It didn't apply to me anyway because I bought my truck used. But if I had a new(er) vehicle and a dealer or manufacturer wanted to deny warranty service or repairs based on the use of a few ounces of MMO they would have to prove to me where the warranty contract specifically states the use of MMO voids the warranty. They would also have to prove to me in writing where it says the manufacturer approves of BG-type fuel services. Surely the manufacturer does approve of BG, they allow the services to be done at their dealerships. And BG44K is a heck of a lot stronger than MMO. That is like comparing 180 proof moonshine to a Miller Lite beer. The BG fuel induction service is also much more involved (maybe invasive is a better word) than just dumping a few ounces of MMO in the tank when you buy gas.

I have never heard or read about MMO causing any damage to anyone's engine or fuel system. That is one of the reasons I started using it to begin with. To be honest about it, I did not read about or discover MMO here on BITOG. I never even knew what MMO is until I first read about it a couple of years ago on http://www.easyfuelsavers.com/. That site only mentions using MMO to save gas, down at the very bottom of their page. Then I started reading about MMO here on BITOG and other internet forums too. I did a lot of extensive reading before I ever added that first dose of MMO to my gas tank, and I have not looked back since.

Too many people post great results from using MMO, both in their gas and oil, and I am one of them. We can't all be wrong.
 
I know I'm preaching to the choir. As with the other users , I have no solid data. I think that is what makes MMO mysterious. I have used it enough in my 350 K mile 528e to know that it makes old engines run a little better. This led to less MPG, probably because pressing the gas was fun. I never got a good process for adding it to the gas tank. It is much easier to add a cap full to every fill up of my small engines, both 4 stroke and 2 stroke. Once again, no hard data, just that I no longer have to fuss with hard starts and gummed up carbs. When the fuel pump on my Willys died, I replaced it with a pump that had been on a shelf for a few yrs. I took the pump apart and removed the diaphragm. As expected it was dried out and brittle. I soaked it over night in MMO . Next day, I put the pump together and it ran the Willys until I scrapped it 10 yrs later. Lately, I've been adding it to make up the 8 oz difference between 4 qts and the 4 liters my 528e takes to fill the sump. Just for the winter. Used moderately, MMO at worst is just a small waste of money. The wonderful smell is reason enough for me to use it. I am convinced that the stuff works. Not dramatically, but there is noticeable improvement in my old engines.

I am putting in(1 ounce 2 stroke oil/2ounces acetone per 5 gallons/20 liters) it really doesn't cost me much. I get the 2 stroke oil free and the acetone from my neighbour the painter. And the fuel computer is showing improvement.


Thanks for the tip, I did this on my most recent fill up and with cold temperatures in the Toronto area -15 deg Celcius I'm seeing a better reading on my fuel gauge. I drive a 98 Seinna with a 3 litre V6 motor.



Even with having to buy 2 stroke oil and acetone, with the current gas prices it's worth doing.

I have two of the old two qt design Inverse Oilers. I think there are parts floating around for them if you search the Internet. You could easily restore them if you wanted. But if the new one is working well that's all that matters.

NIB in box from the 1950s is probably worth more than a few $$$ to some collector. The American Pickers come to mind. LOL

That's kinda neat....but yea, the only real "problem" i see, is sure that keeps the intake nice and clean, it doesn't address the fuel injectors at all....BUT, still kind of a neat "mod"

Might think of doing the on my Aries...just kind of cramped under the hood as is :P So no idea where it could easily be mounted.....

3 oz. sounds just about right....I typically add 2-3 oz. per fill up with my 88 Aries....it has a ~14 gallon tank, and my typical fillup is ~10 gallons....

I have noticed a decrease in performance/MPG though, if I "over dose" i.e.: add more than 4 oz....

My thinking, is that likely anything over 4 oz. to 10 gallons, the MMO knocks down the Octane rating of the fuel.....resulting in problems in that area.....


But yea, I'm a big supporter of MMO in every fill-up, I typically "keep it simple" - using an old 6 oz. bottle of Startron with the 2 oz. markings, it makes it easy to eye ball about 2-3 oz. per fill up....I don't make it a big science event some people will break down to the third decimal place of the correct portion of MMO to use......I don't take it that far :P But I could understand problems arising, if say you repeatedly "over-dose" a tank with MMO, eventually (over a vvvveerryy long time period I'd say) you could end up with a higher concentration of MMO in the tank.


I also add the MMO as top off to my automatic transmission fluid between changes (no more than 16 oz...), same with the power steering...1 pint (16 oz.) goes in with 3.5 quarts of Oil (4 quart capacity) too.

I had good luck with it in a Ford PS pump that had that annoying whining noise. How do you like it in the transmission, notice any difference with it? Thanks
