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.

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.

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.

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. 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.

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.

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.

In some ways, very much so - the car mpg information tells you the consumption for 'urban', 'extra urban' and 'combined' cycles - and everybody knows these are comparative only, that gentle drivers will achieve better and aggressive ones far less. The energy label is also comparative: like cars, some folk will 'drive' their house harder, some will hardly heat it at all. The energy label, however, has pollution in mind, so the scale starts at zero as the best - no energy needed, so no pollution.

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.

We have kept very detailed logs, and even measure our fuel on a daily basis to do some consumption calculations. (Floscan meters would be really nice, but we don't have them.) So, after we subtract fuel used by the generator at a conservative nominal rate of 1.25 gph (Westerbeke specs state 1.42), our consumption for the engines is averaging 5.3 gph in the mix of speeds we choose over the course of months of cruising. That is total consumption, not per engine.

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.

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 Fully Synthetic is also an investment, one that will repay itself many times over in increased reliability and protection for your car’s engine.

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

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, 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.

Model cars run about the same guidelines as boats. A good commercially made glow fuel with at least 18% oil content by volume, not by weight. If oil content is measured by weight a minimum of 20% is required. 5 to 15% nitro content is adequate for general use. Higher nitro content can be used for competition but customer assumes risk or damage.

The energy charge covers the cost of operating and maintaining Entergy’s system. For electricity, this includes the cost of power plants and power lines. To calculate the electric energy charge, multiply the total number of kilowatt hours (kWh) used during the monthly billing period by the current rate per kWh. For gas customers, the energy charge is based on the amount of gas you used recorded in CCF (100 cubic feet).
