Is it safe to use 10W30 engine oil instead 10W40?
12/05/17 at 07:39:41
Hi there.
I have 10W30 engine oil from previous vehicle(car) and I have a lot 10W30(bought from costco).
Is it safe to use 10W30 instead 10W40?
I checked oil chart and found 10W40 is designed to use higher temperature than 10W30. I live in Canada.
Thank you all for in advance for answering my question.
Have a good day

Do not use an automotive oil in a motorcycle with a wet clutch. Automotive oils use additives to improve fuel economy. These same additives cause clutch slippage.
Use a motorcycle specific oil designed for wet clutches or an oil like Shell Rotella T4 15-40

Ditto.
And you are new so probably not following the recent oil thread, so make sure you get the Rotella
T4
and
not the new T6
. The old T6 was ok, but the new T6 has friction modifiers added that are not good for the wet clutch but the new T4 formulation does not have the friction modifiers and is acceptable.

It's sold in 1 gal jugs, and don't be swayed by the fact that it says" diesel" on the jug.

The new Rotella T6 oil (CK-4) does not have friction modifiers, the previous generation (CJ-4) did.

The owners manual says 10w-30 is acceptable at certain temperatures, but unless you're regulary starting under 25 farenheight, there's really no need. The manual also requires use of oil with an JASO MA rating for wet cluches. Our bikes also like high zddp levels because of the flat tappet cam design. Rotella T4 covers all the bases execpt extreme cold.

In my S40 I use T6 (CK-4) synthetic 5W-40, which has Zinc and is JASO MA/MA2 rated. I live in Colorado, but I don't need the cold temperature benefit of that oil as I am very unlikely to go riding if the temperature is below 40 F. I prefer using synthetic motor oil in all my vehicles. Just personal preference, and I am not trying to start an "oil war"! I am sure T4 is fine, and has the benefit of being cheaper.

Nope...sounds forward to me.
The T4 is fine.....the new formula for the T6 synthetic has too much moly and is causing clutch slippage in some bikes.

I am talking about the two different T6's, not the T4 vs. T6.
From what I read, the NEW T6 is ok due to its removal of the Moly.

Nope....the new T6 is the one with the "more moly".

Reading test results previously posted by PapaBear, I thought that T6 5W-40 (CK4) had 1199 ppm Zinc and no Moly, while T6 5W-40 (CJ4/SM) had 1390 ppm Zinc and 71 ppm Moly. The CJ-4 rating is the older one.
If I got that the wrong way around, I am screwed as I recently changed the oil in my S40 from CJ-4 to CK-4. I find it strange both are JASO MA rated if one is going to be unsuitable for wet clutches.
