Cold Oil Change

I know this has been around before, but hard to revive old threads, even when you can find them.
Anyway, my logic here says that if I've been sitting idle in the driveway, for a couple of months, that all the engine oil, should be in the bottom of the oil pan or close. So and since I'm in the tropics here, anyway, why wouldn't it be better to just drain the oil, without starting and warming up first. Even if not so much better, what can it really hurt. I'd just like doing it that way and for changing all the filters, both oil and fuel, genset included, before starting it up and checking all around for leaks and such.
If it's just a case of having a warmer engine, has anyone used their block heater for this purpose and would that be a viable option?
Your thoughts?

Partly it’s because there are some sediments that won’t be in suspension after a long downtime. In RV service I doubt it’s a big deal. Most of us will never wear out the engine.

I agree and tried to do mine after a couple weeks. Couldn't loosen the oil filter until I heated up the engine.

I change my own oil and I always remove the oil filter first so that just in case I can't get it off I'm still able to drive it to my Workhorse dealer who would remove it.

I agree with the OP
after setting for an extended period the max amount of oil is in the drain pan. If I were worried about particles floating around in the oil that would have settled out I guess I could put a rag on the end of a coat hanger and swab out the oil pan.

Personally when changing oil in my personal cars I pull the plug and leave it sit overnight then the next day put the plug back in and fill it up and go on

I to used to buy unused cars and broken down vehicles that had sat around for a while to repair and resell. On some vehicles, I would remove the oil pan and scrape out 1/4" of sludge that had settled in the bottom of the oil pan due to sitting long periods with dirty oil.
I will only change oil when it is hot, preferable after a long haul towing as soon as I get the truck unhooked from the trailer. I replaced a oil pan gasket on my 06 Duramax with 240k miles and the oil pan was clean inside due to the hot oil changes.

Also -- hot oil will flow out of the engine faster and that fast flow will carry more heavy particles with it.

Hot oil that circulated will collect the condensation one the sides of the pan and block.
A sitting engine block is no different then inside a sitting fuel tank, except, unlike a fuel tank, its almost empty.

As far as maximum amount of oil changed, if all of your oil drips down to the pan, its not very good oil. Its supposed to leave a coating.
I have done inframe engine rebuilds after weeks of sitting and they still dripped oil in my face.

When its time to change the oil, it's also time to take and oil sample. And to do that, the engine oil Must be at operating temp to get the correct test results. If you do it cold the soil is not mixed and will through off you testing results. Don't Do It, also if you are not doing it now, hammer a hole in the bottom of the oil filter and drain out the oil before removing it. Way better and easy to handle.


And Caterpillar recommends Not Filling the New Filter with oil before install

Thanks to all who responded.
It seems to be a given for the majority agreeing on running the engine first.
It's also what the CAT manual recommends, so.....
I should probably get started on this today, as I have everything that I ordered now and even if I was to try the block heater idea, that should have been turned on last night.
This is the way, I done it last time and yes I do pop a hole in the bottom of that huge filter to drain and for lightening the load somewhat. Let's just hope I didn't put it on too tight and do have a habit of sometimes, wanting to make sure of things.

I always loosen my filter a bit before I drive a nail into it !
Also, once it starts draining, loosen it till the gasket is a bit lower than the housing. Allows it to drain faster.

Update by OP here:
Job completed and must say that Amazon mobile cart is well worth it and just one oil change pays for it. This is my second with it, so way ahead and not to mention having to drive somewhere.
Decided to run both engine and genset for warm up rather than doing so cold.
Surprisingly both oil filters were not at all tight, even when cold, which is most unusual and to the contrary. Also changed the genset fuel filter for the first time and found it to be a little quirky with the one flexible hose, but still an OK job.
Did notice that the Cat oil filter changed from 3/4 to a full turn for tightening instructions. I did as always punch a hole in the bottom of the Cat oil filter for draining.
Fuel filters were another story and probably because they don't really want to be tightened as much as the instructions so pretty tight to start with.
With this business of priming the fuel after changing the filters, I've found it to be quite effective, for using the pump on the secondary filter and just as long as you pump it up, until you can no more. Started right up, without a sputter this time, rather than hesitating and sputtering for a few seconds.
Thanks for all your input.
