Helped to improve combustion in 12 year old Mercruiser 3.0L engine
Color: Blue, Number of Items: 1
I used the whole bottle in 1/2 tank of questionable gasoline from used boat from dealership, with no idea what mixture of gas water and particulates was in the gas tank in this 12 year old boat. The dealer started up the boat, and it was taking a minute to get the idle going. He mentioned that the gas was a few months old, but I am guessing that is was more like 6 months old. This is the TKS engine, self priming. I think some water / condensate was in the tank. Before taking out to first trip, I added bottle and 5 gallons fresh gas. That trip to the lake, I still has some issues getting it to start easily. Ran OK, not great that day, went home, changed cap and rotor and wires. Next trip, 1 week later, the 3.0L started great, ran great, I am not sure if it took some hours to fully mix and interact with the old gas, neutralize the water, and perform it's reactions, before it made existing gas more combustible, but that is what it seemed like to me. ***UPDATE**** - I had strange fuel issues the next season after using this product. I had to replace the fuel pump and many other fuel delivery components including the carburetor. Not sure if this contributed to the fuel system failing, the long term effects outweigh the short term gains.

Works. . .
Color: Blue, Number of Items: 1
Left 10% ethanol gas in my 3500 watt inverter and forgot about it. After I got it started, it was suging and alsmost unusable even with fresh gas. Drained all the gas and used a measuring cup to get the fuel/additive ratio right and let the generator run wiuth a 1000 watt work light. AFter about 15 minutes, the surging stopped and engine smoothed out. Happened faster than I expected. Taught me a lesson about gas decomposition. Promised the genny I learned a lesson to use stabilizer. Easier than doing a carb rebuild.
