    Sure if you want to damage the engine and you will not be saving much in gas because you will be caring the extra weight of the died engine. Very bad idea!

    Some Bentley's and I think some BMWs can do this but i would think the car would have to be designed to do it. Don't think it's a DIY job.

    Let up on the pedal under your right foot to reduce fuel and air flow equally to all cylinders.

    That will confuse the engine management computer and it will tell the car to limp home.

    It's YOUR CAR. You can do anything you want with it. You don't have to ask MY permission. Of course, since the spark plug is still firing in that cylinder after you shut off fuel to it, it will probably overheat and burn a hole in your piston, but you'll save gas.

      This is not an overly lean condition in a Lycoming O-300; it's a No Fuel condition in a liquid cooled engine where one cyl temp can't vary radically from rest.

    It's been tried . . . . most famously by the Cadillac V-8-6-4 of 1981 which was a disaster: that system deactivated the intake valves on some cylinders - keeping them shut - but the friction loses of the still-moving pistons negated much of the fuel savings and the system was unreliable. After many software

    "fixes", Cad gave-up and just deactivated the system when customers complained. It was kept for a couple years on limos which sat at idle for long periods of time.

    The idea is used successfully on some big over-the-road diesels.

    You could if you wanted to . I doubt it will save you any money most likely it'll damage the engine and cost you money. The motor will run as rough as guts while its running on 3 instead of 6

    No. And, you wouldn't want to.. You'd likely need a new engine!!

      Yes you CAN. Can jump off Golden Gate Bridge. The question is; Should you? No. All of Detroit's attempts to shut down cylinders, except in a big V8, imbalance engine and still have inertia of dead pistons, rods, valves that are parasitical .
