Yes, in viscosity grades SAE 10W-30 and above Caltex Havoline Formula can be used in other four-stroke gasoline engines such as those fitted to many motor cycles, lawn mowers, portable power equipment, etc.

Yes. Caltex Havoline Formula is formulated for use with both unleaded and leaded gasoline. In fact, the qualifying tests for API certification are run using unleaded fuel. Also, Caltex Havoline Formula is specifically formulated to protect emission control devices such as catalytic converters and oxygen sensors, which are often used with unleaded fuel.

The latest engine designs have resulted in increasing demands on motor oils to provide improved protection. The stringent API SL classification reflects these requirements and is now demanded by vehicle manufacturers. Caltex Havoline Formula meets these performance demands and goes beyond them, thus offering superior protection against engine wear and deposits.

Yes. All cars benefit from Caltex Havoline Formula’s friction-fighting properties, high temperature stability and improved deposit control, irrespective of age. These three key properties provide improved performance and prolonged engine life.

Caltex Havoline Formula controls oil consumption by resisting structural break-down, thereby maintaining its viscosity for the life of the oil. Oil consumption is further reduced by control of high-temperature evaporation as evidenced by its performance in the most stringent European ACEA volatility test. In addition, it keeps the pistons free from deposits, enabling the piston rings to maintain a positive seal.

No they are not. Caltex Havoline Formula actually provides extra protection for your engine. It is false economy to buy a cheap, low quality oil and try to compensate for this by changing the oil more frequently. These oils only have enough additives to give your engine minimum protection, and for a relatively short time. Once they are used up, they no longer perform at all. In the long run this means more services for your car, more oil changes and more replacements of expensive engine parts.

Yes. Caltex Havoline Formula exceeds the API SL classification which encompasses all earlier API classifications, including API SJ and SH and the obsolete SG, SF, SE, etc. Although API is a U.S. classification, it is widely used by manufacturers from other countries. Check the owners’ manual for your Japanese car, it will almost certainly recommend engine oil using the API system. Further, Havoline Formula was developed with the needs of the Japanese cars in mind.

Your car is likely to be your second most important investment after your home. Caltex Havoline Energy motor oil is also an investment, saving up to 6% of fuel consumption while providing outstanding engine protection.

Because of the low back pressure limits of gasoline engines, the performance of a gasoline exhaust brake would not be substantial. Because the air intake in a gasoline engine is throttled and the compression ratio is much lower than in a diesel, the performance of a gasoline engine brake would also be insignificant. Because of this we do not offer any retarders for gasoline engines.

Caltex Havoline Energy is designed for use in modern, high performance engines where the manufacturer recommends the highest performance motor oil. Caltex Havoline Energy is generally recommended for use in newer gasoline passenger cars in place of motor oils having viscosities from SAE 5W-30 to SAE 15W-40.

No, the engine will receive complete protection against starting friction and wear, heat stress, and engine deposits. Because of the reduced fuel consumed, fewer harmful exhaust emissions are produced. Caltex Havoline Energy is also compatible with catalysts where fitted, preventing untimely catalyst degradation and maintaining control of exhaust emissions. So users of Caltex Havoline Energy are also helping the environment.

Synthetic base fluids are manufactured over a number of complex chemical stages and are thus inherently more expensive than base oils extracted from petroleum.

Definitely. The benefits of greater oxidation resistance and reduced wear on starting are directly applicable to older cars. Also, the use of Caltex Havoline Fully Synthetic may result in lower fuel and oil consumption depending on the viscosity grade of "the conventional" motor oil you are currently using. A short answer to this question is "Yes". However, oil drain intervals are specified by vehicle manufacturers and published in owner’s manuals.

Several. Firstly, superior resistance to oxidation. Oxidation is an oil degradation process caused by the oil combining with oxygen in the air and accelerated at the higher temperatures experienced in an engine. It shortens the life of the oil and, if the oil is not replaced in time, your engine may be damaged. Secondly, reduces volatility. Particularly in newer engine designs, evaporation can be a significant contributor to oil consumption.

Even though the constructors refuse to divulge details of their engine power, it is rumored that at the beginning of the 1997 season the maximum power easily exceeded seven hundred horse power. Manufacturers of engines with eight or ten cylinders maintain that maximum power is not the only valid criteria, since there is also the power curve which in their case is better at a low engine speed.

SynLube™ Lube-4-Life ? meets the API SL, SJ, SH & SG service classification, which covers most gasoline automobile engines. And is already designed to exceed future proposed specifications. SynLube™ Lube-4-Life ? is not recommended for two-stroke-cycle engines where oil is mixed with fuel.

Both gasoline and diesel fuels are mixtures of hundreds of different hydrocarbons which differ in their chemical structure and composition. During the combustion process encountered in gasoline and diesel engines, these various hydrocarbon molecules mix with oxygen supplied by the air and compete for the combustion reactions in which carbon is converted to carbon dioxide and hydrogen is converted to water.

In 2-stroke engines the lubricating oil is directly mixed with gasoline by adding it into the fuel tank. DurAlt? FC can be added to either the fuel tank of the 2-stroke engine (just like in the case of a 4-stroke engine) or it can be added to the oil prior to mixing into the gasoline.

A gasoline engine is a stoichiometric engine, which uses an efficient combination of air and fuel for total combustion. It intakes a mixture of gas and air, compresses it and ignites it with a spark (spark ignition). Most gasoline engines run in light duty vehicles such as passenger cars and small trucks. A diesel engine is a heavier duty product designed for work in industrial, automotive, and truck applications.
