I generally wait till my engine oil temp reads 50 on the gauge. Set off and then don't go above 3000 rpm until it reads 80 . I want to speed this up a bit
I have been looking at the heat mats that stick to the sump but I cant fathom what happens to the cable .

do you reel it up and stash it under the car somewhere or does it detach from the pad meaning you have to crawl under the car and plug it in every time .


I use quite heavy oil 15/50 in the summer and 10/40 in the winter which was recommended by my engine builder.

@don1952 .
yes this makes sense . perhaps I could locate the socket somewhere where I don't have to pop the hood every time .
I was looking at the wolverine heater , ebay and demon tweaks . it doesn't show any sockets/plugs on their web page .
ill have phone or email them for clarification.


EDIT perhaps I could apply for a grant for a plug in hybrid

When we lived in Alaska (with a Ford Escort Diesel!) we had a block heater and an oil pan stick-on-rubber-mat heater. I ran both cords up so they plugged into one 3-way with a 6-inch cord, and had the male end of the cord sticking out of the grill over by the headlight, out of the way. That way, I did not even have to open/close the hood. I found a black one so it wasn't as conspicuous as an orange one. I used zip ties under the hood to route them out of harm's way. We were there 7 years and the plug was still on it when we left and sold the car.

EDIT: Oops - just noticed you are Brit. I'm sure the 220v cords are similar to ours.

Things have moved on since I were a lad.

We used paraffin sump heaters in them days :surprise:

Its an interesting thought, but would it actually save much time? It would take a lot of energy to heat a few litres of oil and the surrounding metal up to operating temperature. So would you switch it on and leave it heating before starting the car, or have it on for the first few minutes of starting the car? Once the engine is running and the oil circulating the heater is probably having less of an effect I'd have thought, certainly compared to the heat generated by the engine as a whole. However I'm sure it would speed things up and allow you to hoof it a bit quicker in the morning!

@theshootist .
Henry. I think this (like you) is a reasonable and interesting subject.

My car is now a weekend toy / brute and what I really want to do is reduce the running time when cold …..
so if I want use the fsti I would get up in the morning and instead of putting the kettle on I would plug the car in , then put the kettle on and do the usual things folks do before leaving home .
in my case would take an hour, walking the dog , taking out the rubbish, and arguing with Mrs Lockheed about the £60s .
when all this has been accomplished the motor should be near operating temperature .

I contacted demon tweeks and they suggested having a domestic 13amp plug somewhere under the bonnet to plug it in (no way) so I still need to find some neat and small 13amp 240v plug and socket arrangement, preferably water proof.

Most people in the States have them on an automatic timer that comes on 30- 45 minutes before you normally leave for work. Example, if you usually depart for work at 7 am, you would have the timer come on at 615 am and cutoff at 655 am. That way, all you do is unplug it and drive away. When you return home, you simply just plug it back in. The timer cuts it on and off for you.

The timer plugs into the mains, and then an extension cord is plugged into the timer.

this is a good point for a car that is used at the same time every day a timer would be great , this was suggested to me today by an electrician . I m only using my car at weekends now so times will vary .

Assuming the demand is less that 5 amps, maybe you could use a light fitting plug/socket? The male end (that would be on the cable from the car) is pretty small. Might even be available in waterproof (??).

Just a thought...

When I was living “up north” we had a magnetic pan heater that was meant to be used only when stationary, but getting down in the snow to put it on and take it off (on a F-350) was getting pretty ridiculous in my old age.

My Subaru uses a block heater and I feel it does a better job all around and is much easier to use (using an extension cord and timer). As a fleet manager, all of my diesels, about 180 of them, run a block/coolant heater, not oil heater (although we don’t usually get terribly cold, when we do, we need it!) You could always consider a Kussmaul Auto-Eject plug like fire and EMS equipment use. You’ll never forget to unplug it and drive away with the cord dangling like I did in North Dakota once...
