Which Engine Self-Destructs First? Lucas Or STP?

In this video, the goal is total destruction, but in the name of science… and a little entertainment. Our host picks up two brand new engines and brings them home with no other goal in mind than to run them until they die, literally. The experimental part is that the engines will be broken in properly, then treated with an oil additive – Lucas Oil in one and STP in the other – then drained of their oil completely and ran until they fail.

What we learn here is which of these additives offers the most protection in the most extreme situation an engine like this should never be exposed to: running with no oil in the crank case.

The oil is drained, the low oil shutoff switches are disabled, and the engines are fired back up. Not surprisingly, both engines crank and run just fine for a while because most any engine will run without oil… for a while.

With timers setup on each, we see that the STP-treated engine breathes its last breath after running for twelve and a half minutes, while the engine treated with Lucas survives just under 22 minutes before expiring.
