Some kind of wierd dye or what?  It's the first time I've changed the oil since I've owned the bike...so it's been about two years...just kidding  :lol:  ...I've owned it for a month.

It was a definite bluish tint, my girlfriend asked if it was antifreeze.  :lol:

I've heard of dying fluids but never heard of blue dye before.
:dunno:

blue oil      I work for a mobile lube company (jiffy lube on wheels except we know what we're doing) and I've never seen blue oil.  if anyone knows what might cause this I'd be interested.   :dunno:

Does Royal Purple dye their oil blue?  Just an afterthought.

(A little off the subject) I drained blue trans. fluid out of some kids car the other day at work, and read on those stupid ads in mag. about a new 'Racing Synthitic' trans fuid, maybe they sell that too. Some people will buy almost anything if the sales pitch is good.

royal purple is definitely blue-ish/purple. if this is the 1st oil change under your care, i bet the prev. owner used  that.

If gasoline leaks into the motor it may turn another color, I just don't know what color.  Greg has experience with that.  I was just thinking about it because gasoline these days has a bluish tint to it when you look at it while it's being poured.  And Turbo Blue race fuel is definitely blue.

I've used an oil drain pan to grab some drippy gas from a fitting that came loose while I was working on a car - it sure as heck didn't stain the oil blue.  It actually was less miscible than I thought it would be, gas being a solvent.  It made a goopy black mess.

Royal Purple is pretty dang expensive stuff, and synthetic - I remember I was warned against using full synth with a wet clutch when I first came on the board?

I have also heard the probs with friction reducers on a wet clutch.  That is why I've been reluctant to use the Mobil1 synth that I use for my car.  They also make a motorcycle specific synth for wet clutches, but am reluctant to buy that just because it might be the same oil as for cars in a different bottle with a higher price tag and I hate getting taken for a fool.  Plus, I don't even know where to buy Mobil1 for bikes.

I'm going to buy something good for my bike, whatever it is.  And I'm a firm believer in full synth.

Go ahead and use Mobil 1 in either the 15W-50 or 5W-40 varieties without worry.  The 15W-50 is very popular among riders of all kinds of bikes, the 5W-40 is a "heavy duty" dual-spec diesel oil that is also popular.  You'll see people talking about using Shell Rotella or Mobil Delvac 1 in their rides, the 5W-40 is the same sorta stuff.

I have used mobil 1 in wet clutch bikes since 1980 - three of them GS type Suzuki's, one 1960's honda and one Yamaha - before that I used synthetic oil in the transmission of a 1975 RD 350 - never had a clutch problem.  Currently using Mobil 1 0W-40 with no problems in the GS 500

Sweet.  I only have 10w30.  What performance differences should I expect from a 10w40 over a 10w30?  I live in Seattle so the temps are pretty mild.

I've used full synth for the last two oil changes, but 1st time I bought the Mobil 1 found two types, one with anti-friction additives label and the other without it. Now I've only seen the one with the label, so I switched to another brand with no antifriction stuff label...

It seems to me we shouldn't worry very much about those additives, it might be like washing detergent with new XR11-SuperWhite, it does the same as any other, doesn't it?  :mrgreen:
