You could be ducking for cover starting an oil thread.....  ;D ;D

Synthetics are ok as long as you get one without friction modifiers, the old wet clutches don't like the slippery oils.... As long as you change your oil regularly any good oil will do.... ;)

I've read that synthetics have a larger temperature tolerance and have a longer life than conventional oils. I assume these bikes were built for conventional oil but maybe senthetic is better for engine but not to sure about clutch. The bikes design is really odd in that the clutch shares same oil as engine.

You only have to use oil if you're running filter pods.
You know you've achieved perfection in design, not when you have nothing more to add, but when you have nothing left to take away.

Is the Castrol to JASO MA spec? (for motorcycle wet clutch)
 Shell Rotella has been JASO certified since at least Jan 2011

I use Mobil 1 4t 10w40 full synthetic on 550 engine, about 100 miles so far on fresh top end rebuilt, clutch holding up just fine.

Castrol 10w40 regular 4 stroke on 750 engine, 20 miles since oil change, clutch seems fine too.

You're supposed to use oil?   ;)
I use Amsoil motorcycle oil in the  "modern" touring bikes and Shell Rotella T in the old bikes. Canola oil for the popcorn.

The only way to determine if everything is "all right" is to do oil testing over a long period.
I love these people that say "I used XYZ brand in my last oil change and no problems"
Really? What do you expect to have happen? The engine isn't going to suddenly blow up! Unless you used Canola oil....
It's the long term wear that we don't see.
Now where is that popcorn  ;D

If you watch at about 2:30 minutes in this video you will see a Honda will happily run on old cooking oil, it takes much more to destroy the bike,  so in conclusion Synthetic or Regular it doesn't matter as long as it is slippy.  ;D

Gregpripko:  You got to stop acting like a troll.
Seriously.
Oil threads?
Really?!?!?!
Or posting 3, 4, 5 different questions about your "gear shift issue".
Same issue, just 're-worded'.

Curious...I don't see any posts where you told anyone you actually worked on your bike.
Did you try any of the suggestions some of the members put forth?

All of this seems is a bit disingenuous.
Come on man.
You got to get it together.
Come on!  We're burning daylight!

If you expect something to happen, it will happen. You know why? Because of one stupidity and ignorance on how they ride their bikes. Ride it the way its supposed to be ridden, maintain it like the way it's supposed to be maintained.

Castrol 4t synthetic
Repsol 4t motor sport
Motul 3000 4t
Castrol actevo 4t semi synthetic
Shell rotella
Silkolene
Bel-ray
Motorex
Red line
Maxima
Lucas

List goes on.... Want more? Google it. I'm sure it won't be problem, I just put in since my last oil change. "Long term wear that we don't see?" I love it.  How long you need? Many of us would move on with new toys or be flipping these bikes for profit  before you would actually see problems.

Don't forget omega-3 fish oil, good for your health. Take it everyday and hope to see your health improve

Geez, give the guy a break.  Isn't this forum for asking questions and hopefully getting helpful answers?  Not for weird sarcasm and inside jokes.  I know it's a old, heated debate about the oil but I doubt anyone who is really seeking assistance cares about your dumb popcorn references.
