Default Engine Block heater

Hello, looking for suggestions for an engine block heater. (O-320). I will be operating my airplane out a cold weather place.
I see that amazon has a lot of the heating stick on pads! Is that appropriate ? Just need to find the right size and placement?
Thanks for any advice

I use a Reiff preheater with good results. It gets glued to the bottom of the sump. Aircraft Spruce and I think Wag Aero sell them.

Absolutely, Reiff pre-heater. I donít have internet at my hangar so the pre-heater is on a Switcheon cell phone switch.

I have simple stick on sump heaters on both planes (2 on the 540) and they work very well if you close up the cowl adn give them a couple hours to do their thing.

I've been using a Zerostart 3400121 Silicone Pad Engine Oil Heater on my -4 for a couple of years. It fit well on the sump of my (A1A) IO-360. I bought mine at Amazon, though they don't seem to carry them currently. I turn it on the night before a planned flight. Very light, cheap, and convenient.

I have a sump pad heater on my certified plane, and since my hangar is usually warm enough not to need it to fly, I've found it handy to use to heat up the oil for an oil change. Drains much better, and don't need to fly just to warm up the oil. I generally let it heat for about 15 minutes.
