I usually wait until after 3000 miles. And all my bikes engine/trans share the same oil. What 's up with that guy ?
Am I missing something ?
Am I missing something ?
Well there half full of it. I dumped my first oil at 150 miles and replaced it with regular spectro 4 oil and plan on changing it again at 3000 miles with amsoil. I have not decided between 10w-40 or 20w-50. I ran Amsoil in my 1995 Vulcan 750 for over 10 years with no problems. I changed over to synthetic at about 3000 miles.phaed said:was told by 2 different suzuki dealers not to use synthetic oil. one said don't do it on the first scheduled maintenance, but it'd be ok to use it after 3000 miles. the other said not to use it at all. the 2nd dealer said that since the engine and transmission use the same oil, using synth will cause the clutch to slip.
i'm not mechanically inclined at all, but i want to learn this stuff. what are your opinions?

Thanks for the excellent article........I have used Rotella 10W-40W exclusively in my motorcycles......whats produced for and used in diesel engines will without a doubt protect the internals on a motorcycle engine.z109r said:  Haven't finished yet, but saved it.  :read:
I've used synthetic in everything (including my garden tractor) for years without a problem. The most important thing is to use "Motorcycle Specific" oil because additives that are in regular automotive oil will affect the clutch. Of course I've only been in the automotive industry for 31 years so I'm sure he's rightWacky174 said:My dealer told me "Absolutely NO Synthetic"..
He's been in the bike industry over 36 years. He was told by Suzuki not to run Synthetic in this motor. It's was an issue with the clutch plates..
looking to find out more on this issue.
Wacky
If there were any chance that synthetic could damage anything, don't you think a warning to that effect would have been published in the owner's or service manuals?dbritton1963 said:The shop foreman at Ron Ayers in Greenville, N.C. advised that they were instructed by Suzuki NOT to use synthetic oil in the 109's, no exceptions, because of the type of oil seals.
