Good oil...


Exit Wounds

Recommended Posts

I just do not agree to use car based oils in a bike. The foaming caused by the oil spinning in the clutch is the reason in my mind. I know there are guys using it w/o issue and you'll always find the exceptions, but it just doesn't make sense to gamble with it.

Lizard, my Supersport has a dry clutch so the foaming is not an issue for me. I have used Mobil synthetic car oil before but would like to do the right thing. Do any guys you know use car oil in their racing twins? If not, any suggestions as to a good price/performance compromise?

I had a chance to talk almost half hour with a Motul R&D personnel at Indy GP (he is not a product specialist, he was the real shit, gave me his card as well).

This is my sum up:

Best from the top

1. First (Grade V) Double Ester motorcycle synthetic, very expensive like Motul 300V, the motogp guys are runnung 5W40, you can use 10W40 or 5W40 (this he recommends).

Points:

a. The double ester bonds on the metal surface electrostatically and you will never rub metal to metal even in cold start

b. It absorbs water and increases the detergent action.

c. Even if it burns, it almost provides no residue. It can be used upto 277F.

d. It does not suffer shear loss in extreme conditions.

Big Question (The guy's view): Do you need this for a street bike ? Really no. But do you really need a Lambo or Ferrari to go from point A to B, a Civic will do that too. So if you want the best spend the money....because you can.

2. Grade V, Poly alpha olefin (PAO) and Ester mix, expensive, like Motul Etech 100 or Mobil1 Racing 4T.

3. Grade IV PAOs, most other synthetics....all brands are just fine for your daily requrements.

Most will not tell you what is in there, you have to find out from the material safety data sheet (MSDS) which is usually available from the product website.

I have alwyas been told and READ in the manuals , specifically NOT to use synthetic oil in a bike with a wet cluthch...so I dont....and I have no issues.

I realize I am a noob on a cruiser on a primarily sport bike forum so I am not trying to start crap here, but my 07 750 Shadow manual is very clear about it being OK to use the proper synthetic. The non-molly types are fine, Honda even sells their own.

But I certainly agree, you won't have any issues. Good oil is good oil.
