I have put 5W30 in for the winter. Plugged in my block heater. Put a very long extension cord in the trunk. Glow twice before starting on really cold days. This has worked well for me. I also have some D starter spray in the trunk for an emergency. I have never used it. I don't want to find myself stuck somewhere in an emergency and blow my engine up. Has anyone used fluid to start their car with no damage. Can you do this without disconnecting the glow plugs?

I believe that starting fluid in a glow plug engine is very risky.

If you must resort to this, simply disconnect the main cable at the fuse. You could put a high current switch in series with this cable. If you were to do this, see that the switch can handle 50 Amps at 12 volts.

I have seen a post here that indicated that they had done this with no problem. I think they were lucky.

Good luck,
