Premium Quality Gasoline (91 Octane) provides excellent performance in automotive, marine and commercial gasoline engines designed to use leaded or unleaded gasoline. Marine uses include most inboard and outboard engines. This gasoline contains a detergent additive, which cleans and helps prevent deposits on fuel injectors, carburetors and intake valves thereby increasing performance and reducing exhaust pollutants. Its high-octane quality greatly reduces "run-on" or "dieseling" as well as "knock" and "ping" problems. Volatility is adjusted seasonally to provide easy starting in the winter and freedom from vapor lock in the summer.
Midgrade Gasoline (89 Octane) is a superior grade, unleaded automotive gasoline with an octane rating midway between most regular and premium gasolines. It has usage and detergent characteristics that will satisfy the requirements for more of the current auto population, including cars, which can use leaded gasoline. Marine uses include most outboard and some inboard engines.
Unleaded Regular Gasoline (87 Octane) regular grade, unleaded automotive gasoline with seasonal and detergent characteristics similar to those above. This gasoline is designed to satisfy the needs of many late model cars with average octane requirements. Marine uses include most outboard and some inboard engines.
Racing Fuel is a unique product carried by Renner Petroleum. These high-performance gasolines can only be used legally for off-road applications. This gasoline is made from high-octane gasoline stocks such as alkylate and toluene. This gasoline maintains the same quality year round and includes the same detergents found in consumer grade gasoline. While no seasonal adjustments are made, its front-end volatility means it will not cause vapor lock on even the hottest racetracks. It is recommended for all race car events where gasoline is used as fuel, such as formula, sport and stock car races.
It is a Water Magnet - It will pull water out of the air right through your gas tank vent hose. In our high-humidity climate this can be especially harmful to your engine. As moisture is absorbed, the molecules of alcohol/water become heavier than the gasoline in the tank, and they settle at the bottom. This process is called "phase separation".
Unstable Octane Levels - Due to ethanol's high octane rating, if enough water is present in a fuel tank the ethanol can migrate to the water layer, dropping the octane level. This will leave you with lower octane fuel in the tank, and if the separated mixture becomes great enough to reach the fuel pickup tube, it will be sucked up into the engine, where it can clog filters, carburetor jets and fuel injectors.
Solvent Properties - If there is any gum or varnish build up in your tank, the alcohol will dissolve these deposits, and they will be sucked into the engine fuel system. If that weren't bad enough, the alcohol and water combination mentioned in #2 may also encourage the growth of bacteria in the fuel tank which turns into sludge and damages the fuel system.
Please Note! Pure Gas is only available for use in small engines and is illegal for street use. It is NOT available at our CardLock Locations.
