Is it real,or is it memorex

To continue use dino, or change to synthetic. My ride has right at 30K showing on speedo, doe's not smoke,has very good compression,but po might have done a rebuild I don't know. Right now I;m using dino oil from Yamaha, and would like to know if an MC with that many miles can be changed over to synthetic without any negatives,what would be the pros and cons of a change over? thanks Duke

I gotta admit that I don't know either. Perhaps a blend may be in order for a while?

Check out this website when you have some free time: www.bobistheoilguy.com/cms/
There is soo much info in there about oil that your head will spin. Plenty of MC specific stuff too. The long and the short of it is that the synth isn't really any better in most cases. You don't have any warrantee concerns, so save yourself some money.

You can change directly to syn without flushing no worries. Main advantages of syns are that they have inherently more stable viscosity and hold up better under temp stress.

Are we talking semi syn or fully synthetic ?

I changed over to Mobil1 Racing 4T 10W40 at about 40K miles with no problems. Bike even seems to idle better. Ed

Oil Description

the guy I bought mine from told me not to use synthetic. He told me it made the bike leak at all gaskets and trashed the clutch. When I got it, he had just redone the clutch and all seals.

Another friend on a Vulcan told me the same thing, except he said to use a specific MC oil as car oil isn't detergent enough and will gunk things up eventually.

Im stickin w/ dino.

I am looking at Mobil 1 racing T-4,Amsoil M C oil,and trying to find info on Lucas oils because they are into drag,off road,super and motocross with M C's and and cager drag racing but so far haven't got to a site, also trying to find more info on Red Line, other factors to consider are oil slipperiness on wet clutch, and ZDDP. so what sounds best? thanks Duke

If it's all that, why would you even want to take a chance on changing over? If it aint broke don't fix it...

Your friend was wrong about synthetic MOTORCYCLE oils. However, synthetic CAR oil has friction modifiers that probably would cause clutch issues. I suggest you go to the Mobil1 link I provided above and read the description. It discusses clutch. If your bike leaks oil it will still leak oil. If it doesn't leak it won't leak. Ed

So now! We are just about there, only thing missing is the advantages and disadvantages. what are thay. I was told less friction,less wear, helps motor LAST longer. Is that it?? and the disadvantages??

650ED, your answers seem to be more knowledgeable, and your the only reply to give brand name, come on guys educate me.
