I used one on a T-6 aircraft to warm the oil before the owner would fly it. The heater did an adequate job but then the oil tank was seperated from large chunks of metal that would act as a heat sink.
Check with a autoparts store and maybe you could get a dipstick oil heater.
Another thing-- maybe one could use an oil dilution system to get the oil flowing in the engine quicker. The large radial engines used them in cold climates to aid in starting.
