How long does it take for the savings with Xcelplus to pay back the cost of the product?
A If your mileage was to increase by 10% it would take you $1,000 of fuel to pay the cost of the bottle. This is roughly 8 months driving in a car. Other savings also occur. The value of these other savings (like longer engine life, greater reliability and protection from seizing) can easily exceed the improvement in economy.
