Have you ever thought about what happens to gasoline before it goes into your tank? Gasoline is highly refined to provide the right combustibility in your engine, even blending for optimal performance in different seasons. But as gas travels long distances from the refinery to the pump, or sits unused in storage tanks, volatile chemicals have time to evaporate and degrade the gas. On top of that, rising and dropping temperatures can cause moisture to form in storage tanks.

Now think about topping off at the pump – the new gas you’re pumping in may have a different blend quality than the gas already in your tank. This can also alter the effectiveness of your gasoline.

A great way to protect your fuel system from inconsistent gas quality, is by adding a treatment of Dura Lube Severe Fuel System Cleaner. This formula helps the gas in your tank burn through your fuel system more effectively, tackling any moisture in the fuel, and cleaning your injectors and fuel lines. It’s easy to use – just add one bottle for 42 gallons, and add a new treatment every 3,000 miles.
