I earlier posted and said 1.479 oz/liter tof ZDDP  to bring Aeroshell Sport Plus 4 up to about 1,500 PPM of ZDDP. Recall, I said IF  my calculations were correct;  they were  not. Use 1/4 oz per liter...more doesn't hurt and it isn't expensive  either, but a 3-liter oil change only needs 3/4 oz of ZDDP that will  take the Aeroshall from about 800ppm up to 1,500ppm.

  

 Sorry about my earlier error (and I was a math  major too...darn.)

Well here I am having to correct myself on a post. I had heard from a top person (we'll leave it at that) about the lack of ZDDP in Aero Shell Sport Plus 4. You would have thought they knew. But I just had someone send me this document that actually shows otherwise. So never let it be said I won't fix my mistakes. Aero Shell according to an MSDS sheet has 1% -2% of ZDDP. That actually translates to 1000ppm - 2000ppm. So the bottom line is I was misinformed and now it is corrected and Aero Shell Sport Plus 4 is good. So enjoy your Aero Shell. 

I know some of you are tickled you won't need to switch. Now I need to have a chat with my Rotax source.

Aero Shell MSDS attached for proof.

Hey Roger,

Nah, no worries. You're still the Master of the Universe of Rotax in my book . Good to know the aeroshell has enough of this additive anyway. Like I said, so far I've had the cleanest mag plugs at my oil changes with the aeroshell, tho it was always fine with the other oils I used. So I'm pretty sure nothing is chewing itself up in the engine so far. 425 hours and it's still running fine.

Hi Lucien,



Thanks.

I try to be diligent about my post, but I got blindsided on this one. OUCH

Roger,

I hate to rain on your apology but 1,000 ppm equals 1,000/1,000,000 = 1/10th of 1% and 2,000ppm = 2/10th of 1%. Looking at it the other way, 1% equals 10,000ppm and 2% equals 20,000ppm. Has this helped confuse the situation?

Let me see, isn't 1% equal to 10.0000 ppm, or is my math not correct?

One percent is 1 million divided by 100.  This is 1x10ee6 / 1x10ee2 = 1x10ee4.

Therefore 1% is 10,000 ppm.  1000 ppm is 1/10 percent.

I think they might have meant to say .1% and .2%.
