Devi,
Am I right in assuming that refined oils are primarily distilled, filtered and 'cracked' from crude, and that synthetic oils are primarily built up, or 'synthesized' from a base stock, usually an ester?
I had been told that synthetics are more stable than refined oils because the range of compounds that make up the oil can be more precisely controlled. More consistent chemical makeup means more predictable wear, temperature, viscosity, and lubricating properties.
Also, would you agree with the author that 'energy conserving' oils should not be used in wet clutch machines?
