Just out of curiosity, how many of you have tank or oil pan heaters on your vehicles ?

At what temperatures do you begin using them?

My truck has a block heater but I've never used it

I haven't  had one since I have had a garage..last time I had one..I would drop the extension cord out of my 3rd floor apartment window..plug in my truck..then shower and dress for work...start to motor haul up the cord and leave...tank heaters..had them for years

The diesel 350 has a block heater.  I have read that you don't plug it in until in negative numbers. It has been starting fine in the teens.

Nope. There used to be discussions on whether or not an engine "heater' was bad for the engine. I think probably pan heaters are the worst.

I've used them in stationary emergency power generator sets with diesel prime movers.

No, never used one.  The only time we had to heat oil was for the Funny Car.  That was 90 weight oil and we'd stuff the oil cans in the nooks around the tow truck engine exhaust manifold to warm it up so it was easy to pour.

I've installed freeze plug heaters in a couple of cars. Also a heated dip stick. I guess that's similar to being a oil pan heater as its job was to warm up the oil.

Since I don't know what that is, I don't think I do.

No.. never used one.  

My Prius was always parked outside at my old house.   One unexpected benefit of the hybrid system is, the hybrid motor starts the gas engine.  It was just about guaranteed to start.

The only time I used a heater was when I drove to Alaska. Had the dealership add a high temperature thermostat and add a antifreeze heater pump into the cooling system.  It worked really good except for the time we used a bad extension cord. I didn’t know if we were ever going to get it started. It was nice because as soon as you start the vehicle you had heat. Still wasn’t enough heat to keep the frost off the inside of the windshield. I kept an ice scraper between the seats and every ten minutes or so I scraped the frost.

I used to put a small space heater in the cab of my truck and run the cord into the house. I would plug it in when I got up and 1/2 hour or so later when I left for work the cab would be warm.

Just thought I'd throw that out there...

[Tizeye]

Ah, no...

But, I did suffer through Consumer Reports car reviews in the 60' and 70's always labeling an air conditioner a fuel wasting luxury item they did not recommend. They obviously didn't live in Florida or have the standard vinyl seats in their cars.

[Prophet Zacharia]

No.

[Ralphie ★]

Nope. 

[Airehead]

No, we have a heated garage.  The tractor has a block heater.

Not cold enough here in The Land of Pleasant Living.

I have a heated garage but the car and truck won't fit because I have too many dam motorcycles.

And 1 sidecar

Haven't had a car that failed to cold start since the '70s. The one and only car with a block heater I had in the '80s, the one night I tried to use it, we had an overnight power outage.  Luckily it started because it got so cold we couldn't stay in the house.

I think vehicles, batteries and oil viscosity have improved over the years. This weekend it got down to 30 below UP north and the CX started right up. It didn't even whine or complain, much.

Yep, the local electrical provider sold  a heater for this for tis purpose several years ago.
