4k oil change intervals? mobil 1 syn?

The only way to determine if you're oil is okay to continue using is to get the engine good and hot.  Then with the bike in a level position, remove the dip stick, wipe clean and place back in. Do not screw in.  Then remove the dipstick and place directly against tongue.  If it has a fishy taste it's no longer good and should be changed immediately.  If it tasts like chocolate chip cookies, then it's okay to continue using.

Oh and if anyone actually attempts this, PLEASE post it here.  I could use a good laugh.

Is this procedure for Synthetic, or Dino?

It will work with either oil, but the dino will have more of an earthy taste then the synthetic...

Dyno oil wil have "earthy" highlights with hints of oak and herbs, the finish will be subdued, slightly acid, with a touch of smoke.
Synthetics are prone to more fruity touches such as raspberry or cherry with a chocolate finish...

...ya, right.

I think it works for both, but to be sure try it first.
