Customers of Marine and RV Synthetics often realize the benefits of AMSOIL products. One of our customers has told us of how the oil life sensor equipped by the manufacturer would normally indicate oil changes at around 4,800 miles. Since switching to AMSOIL products, the oil life sensor waited until 12,000 miles before indicating an oil change was required. This is a true account.

Another customer has been monitoring his vehicle miles-per-gallons for several years. Since changing over to AMSOIL oil, oil filter, differential Severe Gear, Performance Improver, and an EAA air filter his highway and street MPG has increased 4%.

The owners of Marine and RV Synthetics have seen a MPG increase up to 16%. This is achieved by using the following AMSOIL products: Power Foam, Performance Improver, Severe Gear, Universal Automatic Transmission Fluid, HDD Oil, EAO Oil Filter, and an EAA Air Filter. The products and results are real!
