About O-Sulee Lifetime Coolant

O-sulee Lifetime Coolant is a waterless technology coolant which are chemically blended coolants that result in more efficient engine cooling. This revolutionary formulation is guaranteed to suit the demands of different types of vehicle. And unlike conventional ethylene glycol based products, which are highly toxic and even fatal. O-sulee Lifetime Coolant is formulated with propylene glycol. It is biodegradable, non-toxic & environmentally friendly. The advantage of this product over conventional ethylene glycol type coolants is that the corrosion-inhibiting package has minimal depletion over an extended period of time. This means that maximum corrosion and anti-freeze/anti-boil protection are maintained until the fluid is replaced at the recommended 800,000 kilometres or fifteen years (whichever comes first).


- 15 years or 800, 000kms service life (which ever come first)
- Enables more horsepower, increase engine durability
- Provides optimum protection against corrosion of all metals in vehicle cooling systems
- Protects from boil over, Reduces emission
- Reduces Fuel Cost & Reduces maintenance
- Essentially non-toxic, Safe for the environment
- Guaranteed to suit every vehicle

Propylene Glycol Advantages

What are the advantages of propylene glycol over ethylene glycol?

Lower toxicity:
safe for animals, children and adults

For vehicles:
will not damage paint less pump circulation to get same heat transfer Non Hazardous Waste: avoid disposal costs and avoids main bearing damage if a gasket blows has Safer Propylene Glycol for Antifreeze and Higher Boiling Point

In contrast to ethylene glycol, a potent cause of acute toxicity in humans, propylene glycol is a “generally recognized as safe” (GRAS) additive for foods and medications It is widely used in food and tobacco products, pharmaceuticals, and cosmetics (the main ingredient in deodorant sticks). In certain medicines, cosmetics, and food products, propylene glycol acts as

- a humectant food additive, labeled as E number E1520
- an emulsifying agent in Angostura and orange bitters
- industrial drying agent,
- surfactant, and
- solvent.

Propylene glycol is sometimes used as a de-icing agent; however, ethylene glycol is used more often because it costs less, even though it is a poison. Propylene Glycol has been the safe alternative for vehicle antifreeze coolant in the USA and France for many years. In the UK only ethylene glycol antifreeze coolant was available for retail in January 2010. Switzerland banned the sale of products containing ethylene glycol in 1972.


1. Stop the engine & allow it to cool
2. Remove the bottom radiator hose or drain plug to drain out all the old coolant
3. Refill the system with clean water, then run the engine up to operating temperature, when it is cool, drain & flush again. This will ensure a clean environment for the new coolant
4. Refill 100% with O-sulee Lifetime Coolant, No need to add water


1. Is the engine cooling system of the vehicle important?

The engine cooling system is the most important part of the engine, The primary job of the cooling system is to keep the engine from overheating by transferring this heat to the air, The engine in your car runs best at a fairly high temperature. When the engine is cold, components wear out faster, and the engine is less efficient, emits more pollution and increase fuel consumption. So another important job of the cooling system is to allow the engine to heat up as quickly as possible, and then to keep the engine at a constant temperature.

2. What are the advantages of O-sulee Lifetime Coolant?

a. O-sulee Lifetime Coolant is a waterless technology coolant which are chemically blended coolants that result in more efficient engine cooling. It is specially designed additives mixed with propylene glycol, which is biodegradable, non-toxic & environmentally friendly.

b. More efficient cooling due to a higher boiling point, the increased boiling point of the coolant eliminates the occurrence of boil over, cavitation and detonation.

c. No water, No pressure, No corrosion

d. Substantially fuel economy improvements due to reduce the running time of the fan and higher thermostat temperatures.

e. One successful installation provides cooling protection for the life time of the engine, reducing maintenance time and expenses.

3. Disadvantages of O-sulee Lifetime Coolant?

The only disadvantage of O-sulee Lifetime Coolant is more expensive than ordinary ethylene glycol coolant.

4. Why can O-sulee Lifetime Coolant use in long term?

Experimental data shows that O-sulee Lifetime Coolant can be use 15yrs or 800,000kms which ever come first.

5. Why would the color of the O-sulee Lifetime Coolant become darker after couple months of usage?

The raw material of O-sulee Lifetime Coolant uses petrochemical products, organic, once it is heated it would become darker, rest assured it will not affect the quality of the product.

6. After pouring the O-sulee Lifetime Coolant inside the radiator, the cooling system level shows at the full level, after couple of days, I found out the level of the cooling system is way below the full level.

There are 2 major reason why such instances occur:

a. The original coolant or water is not totally drained, since the boiling point of the original coolant and water is low, after a period of use, the small part of the original coolant and water is evaporated therefore the cooling system level will decline.

b. The cooling system may have a small leak, in regard to this kindly have it check with the auto technician.

7. After installation of O-sulee Lifetime Coolant, there are slightly changes on the temperature gauge?

Commonly the temperature gauge reading will be slightly adjusted due to the previous cooling system and the engine with different variations. Typically for small economical vehicle, the temperature gauge readings will be slightly elevated while for high power engine it will slightly decreased.
