| I hate to be the one to throw water on the synthetic fire, but let's

Regal

The

| lubricant, but I have had engines with non-synthetic oil which lasted

not

one
| good fleet test with a true A/B comparison, with one set of cars running
| synthetic, and the other running non-synthetic, under the same usage
| conditions.  If someone has seen such a test, I would be interested in
| seeing it.
