MMO for a new vehicle?

[JDD]

I personally don't think it is needed in a newer vehicle. That being said, after say 2 years or 30K or so, I would start using it once in a while. I like the lube properties of MMO or Lucas as much as anything, especially in vehicles that have fuel pump issues like GMs have certainly had. I also like regane. I also believe that older vehicles that ran a lot of years on the higher sulphur fuel can benefit from a cleaner like MMO if the previous owner (which is most of them) never used a fuel system cleaning product. I have posted before on my experience with regane and a 98 Ford that was owned by a 'frugal' older couple since new. I asked all sorts of questions about the maintenance they did and what gas they bought, and the guy just sort of looked at me weird and said that they just fixed whatever was broken and bought gas wherever was cheapest and took it to quikie lube a couple times a year. I put the higher concentrate regane HM in the 14 gal tank and drove it fairly hard, and saw a difference for sure. Abt 1 MPG better and it started idling great and actually started idling at the RPM that the manaul said it should. It was about 150 RPM low before the Regane treatment. I now use MMO on every other tank on it to keep it cleaned and lubed.

i would but at very small doses, 2oz in 10 gal or less. bump it up at 50k and a little more at 100k.

Ok so I am confident enough at this point to use the MMO. I will report back and tell you how I make out... The truck is new so don't hold your breath on major improvements. Again, my hope here is just to do a light clean and lube for preventative measures not gain anything in performance or mileage.
That being said, there seems to be some conflicting information on how much MMO to add. I know the dose is 4oz to every 10 gallons but do I only add enough MMO for how much gas it takes to fill the tank or use the dosage on the total tank capacity? In other words, My truck has a 26 gallon tank so would I add 10 ozs of MMO to treat 25 gallons? Or should I only add 8 ozs to treat the 20 gallon fill my truck normally takes to make it full again? Thanks for your continued help!

On the initial dose you add the corresponding amount of MMO to dose the entire tank. On a 26 gallon tank, 10 oz would be about right on the initial dose. After that you add the amount it takes for 4 oz to each 10 gallons it takes when you fill up. If you always fill up at a certain level on the tank, then you will know how much MMO to add each time. The way I do it is I always fill up when my gas gauge is just under 1/4 tank, so I know it will always take 15 gallons when I fill up. So I add my 6 oz MMO to the tank first then pump the gas in. This is the understood best way to add MMO, pumping the fuel into the tank mixes it very well with the fuel. To make things even easier, I carry my 6 oz of MMO with me in an empty Regane bottle. It's a lot easier than trying to measure out of the MMO bottle or use a funnel.

Start at the 4 oz to 10 gallon dose. You may need to adjust and experiment with the dose to get the best benefit. Sometimes a little less is more, especially in winter with the winter blend gas and cooler temperatures.

I have used it long term and it has given me better starts and a slight mpg improvement on some vehicles. I have a commuter I took to 360,000 miles before it finally just fell apart, a ford escort nonetheless. Guess how many fuel pumps it had in all those miles ? Guess how many Injectors I have replaced ? None Never not on any vehicles.........

well I better retract, lol I have replaced mechanical fuel pumps on the older rides. But never an in tank. and thats a grand total of 1.7 million miles just my .02

Well guys it has been about 150 miles now with the MMO added to the gas. I added 10oz of MMO before my last fill up at shell. I can say the MMO is doing something. The exhaust smells different, kinda like sweet smelling, burning plastic, if you can imagine that. This almost makes me think it is lubing the cylinder walls and exhaust valves, thoughts?
The other thing I noticed is lower RPM on cold start up. On a cold 15 degree Fahrenheit start up before the MMO, the engine would start and rev at 1200 RPM for about 20 seconds before it slowly started going down more towards normal idle. On a similarly cold start up after the mmo was added, the engine starts, revs to 1200 rpm but only takes about 5 seconds to start going down to normal idle. Keep in mind the oil, oil filter and gas brand used was the same before and after the MMO was added.
please give me your input as to what this could be, Again, this is just my un-educated guess but the MMO does seem to be lubricating the upper engine and possibly cleaning the fuel system (from the burnt plastic smell in the exhaust). I think I am going to do one more tank of mmo after this then stop and see what differences I notice.

Thanks for the input,
Adam

I use it in our cars too! There is no reason that a UCL and the extra cleaning can hurt anything.

I also notice the smell when idleing. It's the peppermint oil in the MMO. I only smell it when it's cold outside though.

I have found that 4oz per 10 gals. is to much for both my 5.4 liter Ford/Lincoln. I've gone to 3oz per 10 gals and the trucks like it much better.
