Oil Preheater

I'm considering buying a engine oil preheater, now that winter has arrived. Like to keep the garaged hot rod running during winter, but gets cold in the garage.

Any particular brand that has a good reputation, reliable?

Here are a few I have been looking at:

I think your better off with using a heater in the coolant instead of a external heat pad, especially in Utah in the winter, unless you live in St George
My mother, Grand mother and sister all lived further north up in Richfield, Orangeville and Logan. All of their cars had 110 V powered coolant heaters in them

Thanks Cab, thats a good suggestion, except that my max wedge engine has no heater hoses to connect a coolant heater. I'm not in Southern Utah, I'm up north. It was 17 degrees this morning.

I live in Grantsville. I plug in my internal pan heater when it gets real cold and run 1/2 100% glycol antifreeze. My car is in the trailer,

The OEM big and small block heaters I have seen replaced the freeze plugs.

I used to use a heater that mounted in the lower radiator hose.

Use a block heater (frost plug)

I use to buy a lot of those heaters when I was
in the fuel lab(we heated fuel tanks for testing)
.. they work well.. you should buy a controller
for it also otherwise they get way to hot.. pretty
sure most of them are made by 1 or two companies
and everyone puts their name on them
EDIT
If you just plug in straight to the wall plug
you can blow a 20A breaker.. they do draw fair
amount.. thats why a controller should be used
EDIT
After reading the wattage and the size of the
pads you wont need any controller... I am use
to much larger units

I'll also recommend the block heater rather than the oil heater but you'll just have to pick your poison. Chrysler used to sell block heaters over the counter, not sure if they still do or not. Fairly nice little heater that goes into the frost plug on the side of the block and then has a cord that is long enough to run out the front under the radiator. I installed those on my '76 D200 truck since otherwise I couldn't get it started on cold mornings. With the block warm it would take right off. Without any heat it would just crank and crank until the batt was dead.

Most any parts stores up in the cold country
sells those frost heaters.. if you go that way
you wont need a controller(they come with a
preset amp draw).. and they are cheap

What Cab and Andy wrote makes sense. I suppose one might be better for some situations than others. I recall my friends in Wisconson telling me that dipstick ones didn't cut it out there.
Of the three you linked, I'd say the magnet or the adhesive is the way to go. Magnet is removable - I think that what my friends used before they had a garage. But the reason I didn't like the Moroso is that the lack of direct contact will prevent it fro having effecient transfer of heat.

FWIW a block heater came on our '69 Belvidere. I assume it was dealer install. My folks liked to ski and it was common up in ski country (Vermont) for lodges to have outlets for overnight parking.

Well I have been in temps to -60 and colder, you want a block heater and an oil pan heater, glue on pad works the best. THe block heater replaces one freeze plug. There is also an optional battery heater that goes under the battery. I now live in Utah and don't have anything but my garage is heated. PM me if you want some help. Tim

You will also want to put your heaters on a timer, they turn on about 2-3 hours before you expect to leave, if not your electric bill can run $1-200 extra a month....

when the temps I was in got below -40 I also had an electric heater inside the vehicle to just keep the windshield thawed, but at -50 the fan on the electric heater would seize up and not work until the fan warmed up...

Kats sells a good oil pan heater at Oreilly's you only need about 120 watts, anymore is a waste at the temps in UT. There is also a dipstick heater that you can put in that works well. Block heaters are also available at Oreilly's if you do some searching. The battery heater is a pad that is placed under the battery. With 3 heaters, you can get a block to plug all 3 into and then you use an extension cord to plug the block into. Keep all of the wiring under the hood.

If was going to use a freeze plug heater I would put one on each side, not just on one side

In a perfect world maybe but not always necessary.
