Title: Drain Oil Hot or Cold ?
Post by Routy on 11/07/10 at 17:13:55

How do you drain oil, (in any engine) hot or cold, and why ?
I myself have not touched a hot drain plug in years. Just because a book says to do it one way, doesn't mean another way doesn't work just as good, and sometimes better.
Which way gets more oil out,.....and can you prove it,......or should I say, did you ever check to prove it ?

Adjust valves cold and drain oil hot. I don't have to prove it, just do it >:(
Now the "are you on drugs or just stupid" test. :
Your making a rum toddy and discover your almost out of honey. There is just a little down near the bottom of the bear. Do you
A. squeeze and hold the little bear upside down for an hour or three.
B. put the little bear under the hot water tap to heat and thin the honey.
C. add more rum and say screw it.

Hot oil flows out the crankcase, hotter the better.

D. Pour some warm rum in the little bear, slosh it around a while, squeeze it down straight into your mouth.

So really the question is... does oil hold dirt in suspension better hot or cold?  Because of the additive package diesel oil brings into the question, I'd say as long as you stirred it up for awhile, prolonged running to a hot temp isn't necessary.

Bill, how do you do it when you drain your red oil once every 5.68 - 10 years?  Gotta be an important part of your ceremony once you get to the "decade point of change" for your crankcase of Klotz.

Charon, what does the JASO approved Suzuki-Kawasaki-Yamaha literature have to say on the topic of oil drainage temperature?

Where is the required poll !?!   Where is the actual-factual and the nonsensical positions stated for the good folks to argue about?

Yeah, you all are sick -- infected with winter keyboard-itus.   It is going around this time of year.

;D


Likely our grandaddys taught our daddys to drain oil hot in the age of single weight non-detergent oils because it was a needed thing.   The "honey in the bottle" example still works for old style 20w50 oils some want to use today .... so "drain hot" is still the common mind set in the car world.

Modern synthetic multiweights don't change viscosity all that much so I would agree with Verslagen on them.   Diesel oils keep the crap in suspension much better than car oils do, so any temperature would likely work for RotSyn.  I use "non-suffering" fairly durn warm as I am impatient and won't wait for it to get cooler.

My sense of humor likes the "several drops on the inside of the arm" baby milk WARM that Charon will likely find in the JASO uniform method when he goes to looking for it after 5-6 more pages of debate -- old Japanese translators only used one term indiscriminately once they had picked it out of the dictionary.

;D

Note that the "list method" involves tilting the bike right and left to get most of the rest of the oil out of the case covers and head bath.  This is the "improved" method.

Do remember to put the plug back in before adding the new oil -- less messy that way.

Title: Re: Drain Oil Hot or Cold ?
Post by Serowbot on 11/07/10 at 23:21:52

I used to do the "lean right, lean left,... drain the last of the old oil out" method... 'till someone here mentioned...
"Now you've got all the oil out of the head"...

Better old oil, than no oil...  so, now I split the difference...
Lean a little left and right... but not so determinedly...

90% of engine wear, is in the first 30 seconds of start-up... (don't remember where I read that,... but I read it somewhere, and it makes good sense)...
...and, any oil is better than none... so, maybe leaving a little in the head, ain't so bad... 

I may soon get so paranoid, that I never change it again... :-?...

Pour the hot tody into the bear, put the lid on and shake.

Oh, and I always drain hot.  It burns the fingers better that way, besides any waste is still stirred up insolution and not settled on the bottom of the engine.

Vote for as many as fit you.    You can delete your poll and fix it if you screw up something.

Ok, the obligatory B.S. poll has been added to the post to capture the informational data from the respondents who take the poll.


And yes Virginia, you have to vote to see the poll results .....

Title: Re: Drain Oil Hot or Cold ?
Post by Routy on 11/08/10 at 06:31:53

OF,
Thanks for setting the poll I guess,
but I would figure it to be very lopsided to "hot", only because that has been the mind set,..... from probably most owners manuals, and hear say. Years ago when I was still in the automotive tech trade, I asked myself why I was draining it hot. Most times it was because there wasn't time to let it cool, along w/ the mind set from owners manuals, and that was just the most practical way to do it. Some did get drained cold if they happened to set on the lift overnite, others got drained barely warm from driving in the shop. Once in a while one would come off the hiway right onto the lift,....and be hot hot !
IMO, I get just as much oil out cold as hot, or anywhere inbetween. If its cold, the upper end has drained completely, but the crankcase will retain a little more. If hot, it all drains 1/2 assly.
If left to drain overnite, (not recommended on some engines) either way is going to be drained quite well.
Just my thoughts, and only come up when I hear of burned fingers, and I ask, why ?? Kiss ! ;D

Surprise, hot isn't very popular.   Sorry, Lupo.  
Every time I do one of these polls I learn something new, makes them worth the effort to set up I guess.

Post by mick on 11/11/10 at 23:16:36

I always drained hot or very warm,the only reason ? it comes out quicker and I'm usually in a hurry, with my car I take it to jiffy lube for $19 you cant beat it, cost you about the same if you do it yourself.
Besides my B/in law is using the ramp all the time ,and I do not like laying on a cold floor.

Post by JimRR on 11/24/10 at 12:33:07

I change hot. Why, because years ago my Diesel instructor told me to. I do lean the bike from side to side then with the drain plug still out and the filter cover removed I put the bike into gear with the kick stand down holding the bike upright then I turn the engine over a few times and more oil comes out. I usually have my GF to assist because someone has to hold a rag over the side where the cover is, it gets really messy. Regards, Jim.

+1 thats the way I've always did it too.

Post by Routy on 11/24/10 at 13:18:06

I think it still comes down to part of my original question,....which one really does get more oil out, hot or cold.
I myself am convinced I get just as much oil out cold, as hot, because draining cold will get more oil out from the top end, "oil level upward", but will leave more from the oil level downward.


Title: Re: Drain Oil Hot or Cold ?
Post by bill67 on 11/24/10 at 13:34:13

I call it about a tie. But, since cool or cold is easier on me, I do it that way.

Yeah, burning my fingers was one thing, but when I dropped a hot drain plug into one of those closed pans that has only about a 1" hole in the center, thats when I said, "enuff is enuff, never again ! :o

So? What did ya do? Go & buy a drain pan with a bigger hole? Tell us man, dont leave me hanging,,

He hasn't got many choices, he either went after it with a shop magnet through the pan hole or he emptied it when it got cold and caught it then.

Either way gets his bolt back, but both are additional oily greasy trouble.

Since synthetics don't change viscosity very much between finger cold and finger scalding -- it really doesn't make much difference to me.   The bike is generally still warm from the last ride for normal oil changes, but I have done it stone cold at the same time I was adjusting the valves.

Justin, your white jug Rotella T triple protection dino oil now has all the JASO approvals right on the front of the jug now.  

Ain't ya proud that after all those years of us a telling them "motorcycle only" oil boys Rotella was OK in a bike is finally all official now.  Even Charon's using it now.

;D

Grin


Well, I spose so,, but really, I was satisfied that I had listened to sage advice when I went with it in the first place.I asked for input, then I went & looked for more confirmation, then I went with the stuff & Ive talked to mechanics who think its the best oil oput there, For Diesels.
I figure if the viscosity suits the engine & the oil itself is able to go in a diesel,, ( Ohh, & BTW, the reason its "For Diesels" & Not Cars is b/c cars have a catalytic & ther's stuff in Rotella that will kill a cataclysmic perverter. Or So I Hear...

Anyway, to answer your question, I feel kinda vindicated, but frankly, I dont need that, either. Like so many other topics where I am contested vehemently, I dont care, cuz  know what I know.

Doesnt keep me from appreciatin them who teach..

Yep, in an hour I climb in the car for Thanksgiving #1, then tomorrow I drive 6 hours for Thanksgiving #2 -- both of which I am thankful for.

But I thought I'd wish my net buds a happy Thanksgiving before I left.


=======================

If its cold enough, you just palm it when it finally drops free.   I've dropped hot ones in my open pan lots of times in years past, so I relate to what he's saying.

I drop mine in the pan filled with hot Klotz,And was suprised the oil wasn't that hot after a 20 mile ride at 70 degrees I when it and got the plug right away.

Title: Re: Drain Oil Hot or Cold ?
Post by Oldfeller on 11/25/10 at 07:08:06


And being Klotz, I'm sure you could see it all the way down at the bottom of the pan, being that it was still all clean, clear and bright red when you drained it.
