Fuel Additive

The marina uses Startron in their bulk tanks and still have the cheapest gas on the lake.

I buy Marvel Mystery Oil by the gallon and use it on all my vehicles with no problems at all. In fact I bought a used Jeep with ultra low mileage. Previous owner rarely used the vehicle. On the second tank of gas, the engine was misfiring. I check the plugs and two had carbon deposits between the electrodes. Cleaned the plugs, it ran rough for about a half a tank, then ran smoothly since! Even the gas mileage increase by a couple a miles per gallon. Was it just a coincidence that I add MMO to the mix?

I bought the boat used, and it was 'burning' a quart of oil every 60 gallon of gas. Eventually the boat stop burning oil and running a lot smoother. I no longer see a black scum surface on the rear of the boat. Again, was it another coincidence?

My grandfather and father worked on motors during WWII and Korean War. When I had a tour recently at the NG motor pool in Concord, I spied a 55 gallon drum of MMO. If it is good for the military it must be good for civilian use!

You will always get different opinions. This is like asking what brand of beer is best, or who makes a better car, Ford or Chevy! LOL

I have been using StarTron: http://www.starbrite.com/en/startron

I use it at home as well as in my boat.

You can get it for a good price at WalMart. But be aware there are two different strengths of it. One bottle says 'will treat 48 gallons' (1 once treats 6 gallons) and another says 'will treat 128 gallons' (1 ounce treats 16 gallons). The difference is one is more concentrated than the other. There are even stronger concentrations available (1 oz treats 25 gals), but you won't find these at WalMart (perhaps you will at a marina, etc.). This is all the same 'stuff', the only difference is how much you pour in your tank per gallon of gas.

For my boat, I buy the medium concentrated version (1 oz treats 16 gals) as I can put in one 8oz bottle per tank (or 1/2 bottle per tank) depending on how much gas I'm buying at the time: http://www.starbrite.com/item/star-t...ategory_id=585

Oh, with StarTron they say you can't 'over treat' so you don't have to worry about putting in a little too much.

At home (for lawnmowers, generators, motorcycle, snowmobile), I buy the lighter concentration as it's easier to measure out for smaller fuel tanks.
