I believe the issue is.....that the testing cannot be done with the ZDDP remaining intact.  The testing process can identify the contents - but not how they were assembled.  So......the amount of Zinc and Phosphorus in the oil can be determined - but not the combination as ZDDP.  There likely is some way to estimate how the Zinc and Phosphorus in combination are needed to create ZDDP.

And I agree Gary_in_NJ.  The ZDDP level is good - but the moly is creating clutch slippage in the Savage (even though it has a MA rating).  Perhaps a switch to the Kevlar clutch plates would be make this better....or worse?

Zinc dialkyldithiophosphate -(O2 P2 S4 ZN3)"The growth of ZDDP tribofilms increases exponentially with both applied pressure and temperature"...... So go out and flog your bike ,the ZDDP will work even better!

You have the wrong T6, it has Moly in it, which is bad for the clutch.  Look at the text box on the back of the container: it says "Meets API service CJ-4". What you want is the newer T6 oil, now widely available. In the same text box you will read  "Meets API service CK-4". No need to add anything to it, it's good to go as it is.

===================================

Well, crud.  Now I have a huge amount of T6 I can't use in the RYCA bike, and two bottles of Redline synthetic break-in oil I don't need.

Thanks for the timely and useful response, though.

Let's see,.... how advisable would it be to use this gallon of T6 Rotella thusly?
---- Oil change in a 2004 Yamaha FJR-1300 (wet clutch )
---- Oil change in my wife's 1999 Suzuki Grand Vitara V-6
---- Oil change in a 1999 MTD riding mower with a 16hp B&S twin-cyl motor
---- Oil change in a backpack blower with a Honda 4-stroke motor
---- Oil change in an edger with an ancient B&S 3 hp motor
---- Mixed in with gasoline to use in 2-stroke garden equipment (heresy, I know, but when I was a teenager saving for my first two-wheeled purchase, I did this all the time for the 2-stroke lawn equipment I bought used and in the Lambretta)

The lawn tractor and the '99 Grand Vitara would be just fine.

The Honda motor probably requires straight 30wt, same with the 3hp B&S. It will not work as a pre-mix oil.

I guess I will be going to WalMart to get mine!  Does WalMart sell the Savage oil filters too?  Awww shucks!

I try to never buy anything from my local Suzuki dealer. When I need OEM parts I get them through amazon.com or ronayers.com
