Diesel and gasoline rarely mix. Generally speaking, engines that like to run on diesel don’t like to burn gasoline, and vice versa. Of course, there are examples of engines that can run on just about anything remotely flammable. But most engines aren’t designed to handle different fuels.

The folks behind the YouTube channel Garage 54 decided to force one of its many Lada project cars to run on both—at the same time.

This experiment isn’t as complicated as some of their more outlandish paths down automotive insanity. The team simply fabricated a new pair of intake manifolds and installed two carburetors. One carburetor sees gasoline while the other is fed diesel from a remote fuel-cell water bottle. The team’s creative fuel pump might also solve a nagging automotive problem.

Just as you’d expect, the Lada’s engine doesn’t exactly like burning diesel. The host acknowledges a dip in power as the engine started burning diesel, and the engine runs noticeably rougher.

The biggest surprise? Nothing catches fire! Despite the creative use of a water bottle as an impromptu fuel cell, and the web of fuel hoses, this Lada doesn’t suffer a catastrophic end. The whole video is worth watching, especially to see how an engine runs on two separate fuels at the same time.

Have you ever seen a gasoline engine run on diesel? Or vice versa? Tell us about it below.
