Crank engine for lubrication

[qais90]

Hello everyone,

I read somewhere a way build oil pressure in engine before engine starting to minimise cold start friction by disconnecting fuel pump relay and cranking the engine without starting it for few seconds,
Is that really beneficial in cold weather start??
Thanks in advance.

Depends, where do you live at now? And hello 2 U

How long is the vehicle sitting? What year and car is it? If is driven at least once a week I'd just start it and drive. If the car has clear flood mode all you have to do is hold the gas pedal to the floor and crank it, it won't start. That accomplishes the same thing as disconnecting the fuel pump relay, and it's a lot less work.

You can hold the pedal to the floor before you crank and it will crank without starting (flood mode). It does the same without removing a fuse.

Most oil pumps don't move much oil at cranking speed. I think you are better off just starting it.

If it's so cold that you're even thinking about doing it, I'd worry about the battery going low. Sometimes you only get one chance.

Not all cars work this way.

That will get old really fast. Just start it.

There's no need to do that. Just start it as always.

Total waste of time

That's only a concern if the engine has sat for long periods of time, not everday use.

The engine drains the same in 24 hours as if it had sat for a year. But he says in a cold weather start but how cold is cold.

OP can you please be a lot more specific. What engine is it, what oil grade are you using, and how cold is cold in this scenario.

There's plenty of oil left on bearing surfaces after 24 hours even in the cold to provide lubrication before pressure is achieved.

You are making a science project out of this.

That is not true for all cars. Before doing that (which is a good tip) I'd be sure that your vehicle has that feature.

Take the spark plugs out first so that it cranks faster. Do that before every start. When you're leaving the restaurant with your dinner date, tell her you gotta remove the spark plugs and fuel pump fuse to build oil pressure before starting the car.

Thank you, I live in Baghdad where sometimes it reaches -5 in the morning

it's Altima 2.5L , oil 5w30 and it reaches -5c in the morning in winter
