How to start Elantra so it doesn't wind out too high.

mine never does...;-)

Don't worry about it. The only time to worry is if there are freezing temperatures outside during the early morning cold start. As this will damage the engine and wear it out faster.

In which case, an engine block & Battery heater is in order.

If you're trying to prevent engine wear when starting, a pre-oiler is far more effective than heating the oil or anything else.

You're worrying about nothing, as the initial high idle is normal. You can expect to replace your starter prematurely if you continue with this practice.

Tell us more about this pre-oiler. Where does it go? How does it install? How does it work? How much are they? Who sells them? Can every car get one installed? What makes them turn on?

Spoken like a man that doesn't know of what he speaks.

A Block Heater does nothing to keep the "oil" warm. A block heater is placed in the engine to keep the coolant (ie, water + antifreeze) from freezing in extreme cold climates. It does nothing to the oil. For that matter, neither does the battery blanket.

In the Alaskan interior, block heaters were a must to keep your engine block from cracking. Battery blankets were a must to keep the battery from freezing. The only optional item was the little heater that blew warm air into the car's interior - and it worked so pitifully that very few of us used them.

Then obviously it's not going to reduce engine wear as well as pre-oiler, will it? ;-)

Seriously, thanks for correcting me about the function of block heaters.

A pre-oiler is a small tank that installs in the engine bay. It typically holds a quart of oil (which is added in addition to the normal amount). When the engine is running, oil is pumped into the tank by the normal oil pressure. When the engine is turned off, a valve closes, preventing the oil from leaving the tank. When the key is next turned to the "on" position, the valve opens, releasing the oil into the engine again and creating oil pressure before the engine is started.
