Synthetic lubricants are similar to conventional lubricants in that they contain a base oil and an additive package (for corrosion resistance, cleanliness and other specialized functions). However, the base oil in a synthetic lubricant is made from synthesized hydrocarbon base oils, as opposed to natural, petroleum base oils. Synthesized hydrocarbons exhibit better thermal and oxidation stability, and have a higher viscosity index, lower pour point and better low-temperature fluidity. This means they can withstand extremely high temperatures without breaking down like petroleum-based lubricants. Breakdown resistance keeps internal parts cleaner, reduces wear rates and allows for extended drain intervals. Low-temperature fluidity means that synthetics flow better in cold weather, allow easier starts, and reduce strain on starters and batteries. Synthetics are expensive, but the benefits are proven. Fleet experience with their use is reported in this article.
