Racing Applications of RMI-25

RMI-25 Cooling System Treatment has been used in racing of all types. It is safe for the environment and the additive mixture provides needed protection and system maintenance that will keep a high performance engine running efficiently on all cylinders. The following are some key points concerning the use of RMI-25 in motorsports:

• Many racetracks do not think very highly of crashes that may occur resulting in the spewing of a highly toxic contaminated anti-freeze coolant mixture on the raceway. It increases clean-up costs and the opportunity for fines from environmental agencies.

• Since it is non-toxic and biodegradable, it can be used in the cooling systems of virtually every type of racing vehicle. It should be used in situations where there is a potential of damaging sensitive ecological environments, such as rally or off-road racing.

• Though RMI-25 is compatible with most types* of ethylene glycol and propylene glycol ("anti-freeze"), the only time it should not be considered in racing without using anti-freeze is when there might be a danger of extremely cold weather, which may damage the engine. Most racing situations do not need the freeze protection that anti-freeze provides!

• One of the ingredients in the formulation of RMI-25 is a "surfactant." Surfactants are more commonly referred to as "Water Wetters", which are common water additives in racing vehicle cooling systems that make water more effective.

• Other components include rust and oxidation inhibitors that protect the system from deposits that would otherwise attack the system, which could lead to costly part failures.

• It keeps the entire cooling system clean reducing the possibility of hot spots in the engine, which can hinder performance and rob an engine of horsepower.

• Anti-freeze actually reduces water's natural ability to act as a coolant, which is why most anti-freeze mixes call for 50/50 with water. Anything over that reduces the cooling system's efficiency!


There are many racing classes that use RMI-25. A few of these are Sprint Cars, Dragsters, Stock Cars, and various SCCA cars. They do not use anti-freeze unless competing in a climate in which the temperature drops down below freezing. Otherwise, RMI-25 is added to the cooling system as a "Water Wetter" to increase the cooling ability of the water within the cooling system.

Compared to the "other" leading brand of cooling system treatment, RMI-25 just plain out performs the competition, and it is non-toxic and biodegradable! Just look at the labels of other products, including branded store labels and see for yourself!

"If it is water cooled, it needs RMI-25!"

*Do not use with straight propylene glycol.
