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

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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.

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. See similar questions...

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 See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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.
