If you have a car, do you let it warm up for...

A minute or two? ( before using it) I was always under the impression to do that, hot or cold temps outside, to give engine a moment to run. Then once my friend did it too..she said, Im just giving it a minute to warm up ( her dad is a mechanic). But I see many just start it and go in one second. 🤔

Years ago that was especially true but now with the advanced synthetic oils it's less important... still a good idea, but synthetic oils tend to cling to surface inside the engine better than the old, strictly petroleum based oils.

@Ontheroad i watched a thing that said this is a myth that synthetic oil is why the long timing chains fail on the ford engines that it dont follow to the top

@Ontheroad So it comes down really to oil, not just the engine running for a minute?

@Coralmist It's that the petroleum based oils needed the engine to warm up to flow better and get to all the parts more than synthetic oils do. Still a good idea though - not all engines are designed as well and sometimes with more complex engines it takes longer to get parts coated and provide better protection against friction.

@Ontheroad you are bullshitting and you know it

@Whyme Why would I B.S. someone about something like this? Get a grip. There is a lot of evidence, both scientific and pure evidence based to prove what I wrote. Even with that, I did say it's still a good idea to let it warm up, just not as important as it used to be with petroleum based oils. So yeah, take a deep breath and relax.

@Ontheroad modern engines are either overhead cam or roller lifter both of which are very low wear and flat tappet engines do better with high zync content mineral oil like shell rotella the only time your theory would work is a brigs n stratton strictly splash system like a lawn mower
