Oil Pan Heater
Also called: silicone pad heater, glue-on pan heater, stick-on heater
A flat heating pad bonded to the bottom of the oil pan. It warms the oil itself — the thing that actually resists a cold crank.

How it works
Cold-start wear comes largely from thick oil: at -30°C, conventional oil pours like honey and takes long seconds to reach bearings after start. A pan heater warms the oil directly, restoring flow and cutting that dry interval.
Silicone pad heaters bond permanently to a cleaned, degreased pan surface with high-temperature adhesive. Once cured, they're effectively part of the pan and shrug off slush and gravel.
Limits to know
A pan heater warms oil, not coolant — so the block, heads, and cab heater warm up slower than with a coolant-side heater. Many cold-climate drivers run both: a frost plug heater for the block plus a pan pad for the oil, on a single splitter cord.
Pros
- Cheapest effective permanent heater
- Easy DIY install
- Directly targets cold-oil wear
Cons
- Doesn't warm coolant or cab heat
- Adhesive install is one-shot — prep matters
