Is it true that before changing the oil on a motorcycle you need to let it warm up for a few minutes?

if so why? and why is it that on a car you don't have to do that?Is it true that before changing the oil on a motorcycle you need to let it warm up for a few minutes?
The first answer is correct: all engines should be warmed up before changing the oil. This is because oil gets dirty from use and the accumulation of dirt %26amp; metal particles. After the engine cools, these particles settle to the bottom of the oil pan making a sludge.





If the oil is cold, that sludge stays in your engine during an oil change and is recirculated in the new oil, defeating the purpose of changing the oil in the first place. Warming the engine resuspends those particles into the oil, and you drain them out before adding new oil.Is it true that before changing the oil on a motorcycle you need to let it warm up for a few minutes?
c'mon son, just warm it up, its better for the engine cause youl get most of the old oil out and better for your engine spirit. thanks for asking!!! also, for a car they normally do the same, it gets the sludge out better when the oil is hot. nuff said, party on!!!!!
You don't ';have'; to, but it's a good idea.


Warm oil flows faster/easier/quicker than cold, thick oil.


Plus, the grit/sludge/gunk/debris will be mixed better with the oil, allowing more of it to flow out with the draining oil.
on any and every engine,car or bike,it always helps to warm the oil up...when its cold its thicker,warm its thinner and drains quicker/better.
Actually any internal combustion engine should be warmed up before you change oil.......It allows you to drain all the old oil
I just drain it, fill the oil tank with kerosene, run it for one minute and drain it again and then fill with fresh oil. The kerosene cleans the motor out real well.
no. Most modern oils are that thin they don't need to be warmed up to drain. This idea goes back to the days when engine oil was thicker than porridge.
