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.

While high performance motor oils, such as Caltex Havoline Formula, can certainly be blended from well refined mineral base oils, for ultimate performance we need to use the specially tailored properties of a synthetic base oil as our starting point.

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.

All motor oils are made up of base oils and additives. In general, fully synthetic motor oils contain non-conventional, high-performance fluids. Semi-synthetic oils (also called "blends") usually use a small percentage of non-conventional, high-performance fluids in combination with conventional base oil.

AMSOIL Synthetic Motor Oils are high performance, extended life oils manufactured from premium synthetic base stocks and special purpose additives. These "designer oils" (so nicknamed because their molecules can be structured to do a specific job) provide significant improved overall performance benefits over conventional petroleum oils. Top

Yes, it is. To meet the demanding requirements of today's specifications (and our customers' expectations), Mobil 1 with SuperSyn uses high-performance fluids, including polyalphaolefins (PAOs), along with a proprietary system of additives. Each Mobil 1 with SuperSyn viscosity grade uses a unique combination of synthetic fluids and selected additives in order to tailor the viscosity grade to its specific application.

Most engine oils are blended from conventional mineral base oils, extracted from streams produced in the refining of crude oil They are a complex mix of many different hydrocarbon compounds, some having very desirable properties for lubrication, some less so.

Yes, AMSOIL Motor Oils are compatible with all other synthetic or petroleum motor oils. However, the mixing of AMSOIL with other oils will shorten the effective life of the AMSOIL lubricant. Top

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.

AMSOIL synthetic motor oils are fully compatible with all petroleum motor oils, and there is no danger in mixing the two. Mixing AMSOIL and petroleum oil, however, is not a recommended as a general practice. Performance and long drain intervals will be sacrificed and the oil should be promptly changed, at maximum, within the next 3,000 miles. AMSOIL Synthetic Motor Oil can be used during break-in trouble free.

The high engine protection performance and fuel economy provided by this exceptional engine oil requires the use of a complex combination of performance additives and friction modifiers, as well as an expensive synthetic base fluid.

Yes, synthetic oils for passenger car and light truck use are fully compatible with petroleum oil and other synthetic lubricants. But, even though they are compatible it is best not to mix different brands of oil. Each brand of oil has a specific chemistry and additive package and two different oils mixed together may result in optimal performance as they were engineered to if the chemistries of the oil becomes offset by mixing with another brand of oil.

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.

AMSOIL Synthetic Blend Motor Oils are a blend of synthetic fluids and petroleum oils. They are combined to form an all season motor oil that demonstrates many of the performance features of synthetic lubricants.

Absolutely not. Both petroleum motor oils and synthetic motor oils have additives blended in the oil to control seal swell, shrinkage and other engineering parameters.

It's all in the formulation. Because AMSOIL is made with synthetic basestocks, it resists thermal and oxidative breakdown, which suits it for extended drain use. AMSOIL pairs top-quality long-life synthetic basestocks with top-quality long-life additives. The fact is, other oil companies don't use the quality additives AMSOIL uses because it simply doesn't pay to pair long-life additives with short-lived conventional basestocks.

Mobil 1 is fully compatible with conventional motor oils, semi-synthetic motor oils and other synthetic motor oils, should it be necessary to mix them. However, it is important to note that the superior performance of Mobil 1 will be reduced by diluting it in any way.

There are also oils that have had natural or synthetic chemical components added to them after distillation, to boost the level of certain components that makes the oil more attractive for certain purposes. These are sometimes called reconstituted oils.

Synthetic oils are formulated to perform better than petroleum oils at both high and low temperature extremes. That's why every jet engine in the world is uses synthetic oil (and have from day 1). AMSOIL Synthetic Motor Oils have extremely low pour points and flow easily at extremely low temperatures for easier winter starting and significantly reduced engine wear. At high temperatures, no conventional motor oil can compare to the overall protection AMSOIL Synthetic Motor Oils provide.

Some are and some are not. The only way to know for sure is to go by the oil manufacturers specifications. This can also be verified by oil analysis testing at different intervals during use. AMSOIL INC. specifies 25,000 mile/1-year drain interval and 35,000 mile/1-year intervals with the 0W-30 Severe Service synthetic, without by-pass filtration. If by-pass filtration and oil analysis is used, then drain intervals can be extended until the lab results indicate the oil needs to be changed.

Vehicle manufacturers recommend lubricants by performance classifications, rather than by base fluid type. They are concerned with the performance of an oil rather than what it contains to achieve that performance. Naturally, Caltex Havoline Fully Synthetic is formulated to meet and exceed the very highest manufacturer and industry performance specifications, including the benchmark API SL and ACEA A3 and B3 categories.

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.
