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.

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. 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.

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.

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. 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.

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.

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.

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.

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.

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.

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.

Yes. When used in mechanically sound engines, AMSOIL Motor Oils can reduce oil consumption. However, AMSOIL Motor Oils will not "fix" an engine that has other mechanical problems causing excessive oil consumption.

We've found that it does vary slightly but the average seems to be between 500ml and 1 litre every 3000 - 4000 miles.

Oil consumption is a phenomenon unique to internal combustion engines and consists of many separate mechanisms. Because internal combustion engines are fueled primarily by burning of hydrocarbons, and lubricants also are flammable hydrocarbons, it is only natural that some of the lubricating oil is also burned in the combustion process.

Our Oral Chelation / Age-Less Formula does contain EDTA. EDTA is a synthetic amino acid that has been used in intravenous solutions as a therapy for heavy metal poisoning and cardiovascular disease. While it is effective as an intravenous therapy an oral dose of EDTA is rather poorly absorbed (4%-15% of total dose).

Yes. The terms “synthetic”, “semi-synthetic” etc relate to the type of base fluid from which an oil is blended. Apart from base fluids, lubricants also contain additives, all of which are synthetic. There are many types of base fluid which may be described as being “synthetic”, each having their own properties and advantages/disadvantages in particular applications.
