Hot oil or cold oil change..!!!

Here's the scenario,,,

I'm going to get rid of the crap oil they put in at my recent service check.

The bike has been sitting the garage for a week now. All the oil and any crud with it, will have gone to the bottom of the engine/sump and should be sitting right over the drain pug. Starting the engine and getting the oil nice "n" warm again then draining it wont really prove much will it, as all that crud (if there's infact ANY at all) will recirculate and then settle right back down to where it is sitting right now - right...!!! Draining it right now would seem to be the more logical thing to do.

Or would it...???

Opinions...

I'm heading into town right now to get another filter - may as well change that too, as it wont hurt...!!!

what was the oil old and cleaned on site and put back in? just wondering how any motorcycle specific oil can be that bad. Unless they put the wrong oil in.

I agree that a WARM oil change is always better than cold. That being said...

Depending on your current temp in NZ here's another suggestion CB-

I agree with your theory that a lot of the crud has settled to the bottom of the pan and may be churned up by running it. BUT, warm oil will settle (with nasty particles) much faster. Buy an extra quart of whatever blood you plan on running. After you drain the stuff you're not comfortable with - dump the fresh quart thru and let it drain on out.

Wasting precious oil, yes.

Flushing out more of the nasty particles, yes.

Do it myself occasionally - that is before oil got so crazy.

It's a fool who looks for logic in the chambers of the human heart.

As stated above:

Always Hot and Always change the filter!

Why? Hot oil will drain easier and will have any bad particles floating in it and when drained it will take them out with it. Cold oil will have separated from the bad particles and will leave them behind.

Change the filter!!! First; why would you not insure your motor for 6 bucks? Second; when you put in clean oil it will break down carbon build up and carry it to the filter which has already performed this duty with the current oil change, you would be taxing the filter beyond its intended purpose. yes it will work, but after several thousand miles you now have a filter that is as dirty as one with twice the mileage. Third; Why would you not insure your motor for 6 bucks???



I change my oil & filter every 6 weeks! Over kill? Sure is, but to me it is cheap insurance! I also do the 1 quart flush every time with new oil.

6 weeks!?!
If I waited that long I'd be two changes over due! LOL

I do mine every 2000 miles. Oil & filter. Hot!!! 2-5 minutes after a ride.
Comes out like new, and all the crap (if any) with it.

I change mine cold and always change the filter. While warm oil flows out the drain hole easier I figure the filter should have caught most plus thru out the years I have gotten tired of burning my hands.

Yea, that would be about 2k for me also. I've always had ATV's and everyone went by hours of use. The 450R I had didn't even take one quart so I just changed it after every ride. Got the filters for 2.50 each so it was cheap to change the oil and filter. Again, just cheap insurance! When I split the Cases to install the stroker crank, all the internal parts looked like NEW even after two years of hard riding.

It's just that brother and I were arguing the merits of both ways. I have always done the "hot" change and so has he but since the bikes had been sitting there for the past week, and all that was going to settle doen at the bottom will have done so, I thought - why not just undo the sump plug and let her run. Surely nature has done most of the work for you already, while the bike has been sitting there.
Yes oil filters will always be changed with each oil change, but I was merely trying to nut it out as to why I should heat it all up when the idea is to simply get all the oil out and all the crud will be already there just waiting for daylight to appear through the sump plug...

I am going for a ride tomorrow so I will most likely now wait until I get home and do it then. That way I can make sure...

Barmatt80 - We noticed with the VTR's we had from the same shop, the gearboxes both performed more clunkily after the first service and oil change. As soon as we did the next oil change oursleves with decent oil, it was silky smooth again... My brother changed his oil today and his 919 'box once again smooth. I don't know what they use but it is definitely not up to our standards...

Does Honda put in a break in oil from the factory and that's why it's changed after the first 600 miles?
I mean, I changed mine too but I was just wondering if they did use special oil?
Anyone using Mobile One or AMSOIL, How's it working for you, is everything smooth? I have used Repsol syn. so far and been pleased so far but I have been approached by the local AMSOIL rep and he, of course, wants to turn me on to his brand of oil.
Thanks Y'all

In my opinion all motorcycles should come stock with an hour meter. In the mean time I use these on all my machines.

A week isn't anything for any engine to sit. Plus, all that oil sitting in the case has been filtered through the filter. Now, it won't flow very well if it's cold, so It' will take longer, plus, if there is any poop(crud) in it, it will be shmucked to the bottom of the case where it will tend to want to stay in its ucky mucky coldness. This is just echoing what Ripper said above.

Anyway, I'm sure you do, but always change your filter with your oil. My filters don't exactly come cheap like 6 bucks, but I figure a new one at 12 doloroonies is cheap insurance.

Ride on Kiwi Bro!!!!!

You are 100% Correct Hasbeen! IMO Everything should have an hour meter! Especially Autos!!! You find a nice 10 year old car with 30K on the clock but if you had an hour meter you'd find it had spent 80% of its life sitting idle at red lights!

Not to mention Dirt Bikes, Quads and other toys that are not monitored! Come on, how many used Dirt Bikes and quads have you seen listed for sale and they say it ONLY had 10 Hrs use on it??? B.S. I say!

I was going to put an Hour meter on the old 450R but since I changed it so often I didn't really see the need. When I sold my quad everyone would ask how many hours are on it! I told them "A LOT" it scared some people off but they were not who I was targeting. Not many people are going to spend what I was asking for a 3 year old ATV, it took the guy that knew what it would cost to build the same machine and to see the passion I had for it to know and believe that I truly did maintain the fluids as stated.

Remove drain plug, remove filter..... head into house to sit on WT for awhile while oil drains...... come back out and finish up.... Done.

If you do 'hot' oil changes I would invest in a pair of mechanix gloves.

Hot oil tends to burn... and keep burning for a while.

Mechanix gloves soak up oil.

Better off with a rag & thick latex gloves.

I personally have never been burned by hot oil.

Even after changing the oil on hot cars &/or motorcycles.

I guess I just don't let it get me.
