There’s nothing more important to the performance of your vehicle’s vital systems than the proper oil and fluids. So whether you’re maintaining your daily driver or pushing a top fuel dragster to its limits, we have the conventional, blended, and fully synthetic oil you need to minimize the damaging effects of heat and friction. And we have more than oil—get the coolant, transmission fluid, gear oil, brake fluid, and octane-boosting fuel system additives that help your vehicle run stronger longer, plus the sealers, gasket makers, and epoxy you need to ensure a leak-free seal and efficient operation.

DEI Radiator Relief

Radiator Relief is simply the best coolant system additive on the market today. It's made for use with water or anti-freeze and is designed to function in two ways: It eliminates high temperatures in your passenger car, street rod, racecar, RV, etc., and will reduce the temp as much as 30 degrees F. It also provides a 50 percent quicker warmup time. This characteristic is not only beneficial to motorsports pros, but also to daily drivers who can enjoy the comfort of heat in half the time on those cold mornings.

DEI Radiator Relief Coolant Additive for Diesels

Radiator Relief for diesels is a specially formulated performance coolant additive that is concentrated to enhance today's large-capacity diesel cooling systems, and blended for extreme use. Radiator Relief for diesels reduces the surface tension of diesel engine coolant and maximizes the transfer of heat more efficiently from the engine to the radiator. In addition, with its special anti-foaming agent, it promotes superior coolant contact in the cylinder head to accelerate the heat transfer process. Adding DEI Radiator Relief for diesels allows engines to run up to 30 degrees cooler and reduces engine wear, which occurs during extreme temperatures and under heavy loads, such as when towing and climbing hills. Radiator Relief for diesels includes a corrosion inhibitor that balances the negative acidic effects that can develop over time in antifreeze and water solutions. It also stabilizes the pH level, which helps reduce rust and prevent electrolysis, mineral deposits, and pre-existing scale buildup from forming on the radiator, resulting in potential core damage. Radiator Relief for diesels is compatible with all types of water and antifreeze mixtures. It is also safe with all alloys (including aluminum), and is water soluble, 100 percent biodegradable, non-corrosive, and non-toxic.

DEI Quick Heat

DEI Quick Heat is specially formulated to get the heat from your engine and into your heating system faster—especially in frigid climates. Quick Heat works by reducing surface tension in your coolant, preventing cavitation; the formation of tiny, insulating bubbles—and fewer bubbles means a more efficient transfer of heat from engine to coolant to cabin. Simply pour DEI Quick Heat into your radiator/cooling system and feel the results! Additional features and benefits include: * Safe with all coolants * Get warm in half the time * Leave Quick Heat in your system in the summer to maintain the same heat-transfer efficiency and actually lower coolant temperatures in hot climates * Enhances benefits of a remote starter
