Oil changing question

The only way that would be better is to drain it. Put new oil in. Run it and change it again.

That's the way I've done it in the past... Drain/change, put new oil in, run, drain/change. That's ONLY if I had a bunch of miles on it before I stored it though... I always tried to time my oil changes to at least 75% ready before storing.

its not that the oil is old either, hell it prolly has 1500 miles on it and thats all

I'd just run it then... Run it, hell put a couple of easy miles on it, then drain it hot and put in new.

some screaming eagle stuff or something like that. I have been fine using the rotella in the aprilia but want to make sure I stick with something speciffic for the buell, I was going to proily use the motul I use on the track bikes.

I didn't change mine before "Winter" either....because it only last a couple weeks!!!!

Seriously guys, I'm not out to start the "storage routine" argument again but if your bike has been parked less than a month or two, I really, really doubt that it matters. Seriously, what happens to oil sitting in an engine that doesn't happen sitting on the shelf? Besides, I always run mine once a week or so just to keep the battery fresh.

Condensation, fuel, carbon, emulsion.

But, I agree a month is nothing.


This is emulsion..

So without the engine even running all those things happen to the oil in your bike? How? Where does this moisture come from? The fuel? Any of it? Aren't those things conditional on the engine running and if so, once the engine is stopped the contamination process stops as well? My thought was that you should change your oil BEFORE storing your bike to prevent the moisture, etc from doing potential damage but since he(and I) didn't the "damage" is already done and changing it now won't help anything imho. At any rate, isn't this just another one of those old tech tips that applied to bikes with cast iron blocks, heads, rings, etc and don't really apply to modern bikes made out of chromed cylinders, aluminum blocks, Ti valves, etc?

You ol' ninja editor!!! I know what emulsion is and it can't happen without the engine running, if it could then new old won't fair any better. BTW if you have that much water in your oil, there's something else going on there chief!!!

bTW I know guys that believe you should change your oil before Winter AND after! The oil companies just laugh their way to the bank!

Ideally, you should change your oil before storage and not start it again until you're ready to ride.

Emulsion occurs because you run your engine without bringing it up to a hot enough temperature to evaporate any moisture that collects due to temperature changes.

A very small amount of fuel would get by from regular use. Carbon blows by your rings. When that mixes with the moisture from condensation it becomes acidic.

This applies to all engines. However, it really probably wouldn't effect your bike very much. That doesn't change the fact that it doesn't happen.
