Absolutely NOBODY here will be able to tell you with 100% certainty that not changing it will be bad for your bike, but I CAN tell you with 100% certainty that changing it will NOT be bad for it.

Cool, I spent my college years working on MBs, GPWs, and even 2 Bantams.  Also M38s, Dodge WCs, IH Ms, etc.

In a nutshell, Willys got the contract to build the first 1/4 ton utility vehicle that we now know as a jeep.  It was designated the "MB."  (There was a somewhat different vehicle called the 'MA')  WW2 was beginning, and Willys was a relatively small company without the manufacturing capability to meet the demand for the vehicles.  So Ford was licenced to build them, and their version was designated the "GPW."  The MB and GPW are not identical, but all parts are interchangable and otherwise look the same to a casual observer.

The derivation of the 'jeep' name is a controversial one, but the idea it came from GPW is one of the theories.

Aaaah thanks, Willys!

My older brother had one, a 47 I think, when i was a lad, 1958+/-. It had a power take off on the rear and he pulled a bush hog and mowed farms with it. 4WD low range. Rusted out like swiss cheeze.

We used to ride/drive it in the fields. Pretty primitive basic vehicle. Fun.

I agree with Lordmoonpie and Ofreen.

I'll toss this in the mix as well....

Motorcycles are different than cars when the engine oil is also the transmission oil. Transmissions put alot of strain on oil and cause it to break down much faster that just an engine running by itself.

Additionally,

How much moisture you get in the oil varies based on the type of enviornment. More humid = more condensation.

Imagine a Cold beer on a hot day...Yummmm....Condensation just running down the bottle.......

An engine is the reverse....Cool on the outside...warmer on the inside. WHere do you think the water droplets form? Yeah on the inside.

But like I said...Humidity. Winter can play havoc if you open your garage frequently.....Warm bike and cold air. If its tucked up and stays a constant temperature...well thats a different matter.

If you live in the high desert like Arizona or even Denver....the humidity and moisture problems are not going to be the same as Venice beach or South Florida or Texas.

Sorry, guess I should have said "nobody can prove to you with 100% certainty".  Knowing something and being able or willing to prove it are two different things. 

In Heffay's specific case, under his specific set of circumstances, there's nothing anybody can say or do here that is going to prove, beyond a shadow of a doubt, that using the oil that's been sitting in his bike is going to cause it any harm.

I still say change it, though.

I know the oil faq and have read it.....doesn't mean that I can't ask the question again..since I felt the faq did not address the question that heff asked and I added to it his question on type of oil for the milage/time.

I agree with ya'll every word. Oxidation is the worst for oil, I wanted to start a thread on a certain synth. that I have talked about several times but never got a response on it.
I mainly wanted to see if anyone else has tried it, I have started my new ridin' lawn mover(which has a catylitic converter on it :P ) and its on its thirs year now and the oil I used in it went from a lovely purple color to a light shade of brown after one year of use and about 150hrs use, no burning/loss of oil and.....With this oil there is literally no oxidation factor to worry about it attacking all the goods hiding inside the cases. ;)
It would be cool to have a simple oil faq that posted different types and effects that were noticed, like markcb750 said, I have done this in different old cars and you can see the difference, in startup (in the heat and cold) and looking at the stick too, feeling it in between fingers, and clutch feel also. Most oils turn brown or black the first time they are heated up good so it can get confusing.

Good post Goon......NOW.......go to the SEARCH function!!!!!!!!............just kiddin'.........................(KINDA!!!!!!).
The only thing I ever really got outa all these oil discussions is that the newer oils have additives that aren't designed for our older bikes.Some use diesel oil (15-40),Honda specific oil,etc. The biggy is if you use modern oil that will f%$k with yer clutch.I say.......get on the FAQ and decide for yourself!!!!!!!................. ;D..............now .....go away and decide for yourself!!!

Tee hee hee, I know Mr breeze, bit my tongue as I typed it...
I just liked the fact that the stuff I used has no oxidation factor and would be good to sit in an engine and start from time to time so things can keep a film of lube on it.
We all need a good film of lube on it  :P

Not exactly. What MRBreeze is saying is correct. He mentioned "Honda (MC) specific" oils and that's the point. Modern oils are split now into "Frition modified" and "non-friction modified". NFM may be considered non-modern, but that's a misnomer. Better to say NFM oils are for diferent applications (MCs). My modern Yam 2003 FJR uses the "non-modern" NFM oils. See?

My Yamalube (dino oil) is API-SJ " non-friction modified". The Friction modified oils are mostly designated with API Service S (with second letter higher than J). The SJ is an all inclusive level for the SE, F, G, and H.

We used to be able to say auto oil was no different than MC oil. But once the friction modifiers came in (early 80s I think) it became incumbent to look for SJ or less oils, for tranny and clutch issues.
