Can you use regular SAE10W-40 motor oil in a motorcycle. Or does the oil have to be specific to a four stroke engine motorcycle engine. What happens if you have already? Sorry for the ignorance on my part.

You should avoid oils that carry the "Energy Conserving" label on wet-clutch engines, as some of the additives in them can cause clutch-slippage. Typically 0w20;0w30; 5w20;5w30;10w30;10w40; are all EC-II oils. I do not know if the M50 has a wet or dry clutch, or if it will "for sure" cause slippage.

I generally use Mobil 1 synthetic 15w50 in my FZ6 - no problems in over 60,000 miles.

The M50 has a wet clutch. I just bought an '06. Should be fun. I'll be using synthetic (motorcycle oil) in it, but that's just me.

Rotella-T, @$11 per gallon should do nicely.

Suzuki advises against using synthetics, just so you know.

I like the mobil but been using motul for so long.

Is there a specific reason not to use synthetic in a Suzuki bike?

I would think the only reason Suzuki might have qualms is the clutch. Perhaps the composition of their discs has a tendency to slip with some synths? Easier just to say "No Synth" than find the actual culprit.

(then again, what most of the oil-manufacturers call "synthetic" nowadays is just a lie)

No. I've had Repsol, Castrol, and Mobil synthetics in my Suzuki for 30k miles. No issues whatsoever.

When I had an old Harley, the mechanics went ape about running multi-weight synthetic in it. Then I showed them the 60 degree temperature drop and they simmered down. I ran it for 15 years with full synthetic, not one oil related issue. Aside from leaks...but those were factory-installed.

Admittedly Iv used it in the race bikes and even under that extreme condition Iv never had the clutch slip. Airhawk hit it on the nose it's supposedly what's in the fiber plates that's supposed to make the clutch slip.
