Question:
What's the Source for Synthetic Ester Oils?
Are synthetic ester oils derived from crude petroleum?
-- Brian Oxendine, Maxton, NC
Answer:
Synthetic ester oils are not derived from crude petroleum. The fluids are manufactured using a fundamental reaction of two compounds: an acid and an alcohol. Many types of acids and alcohols can be used to manufacture esters. Careful selection of these starting compounds tailors the final ester fluid to be superior in the properties desired.
