By 1975 catalytic converters were on cars.

Thanks Dave!

 

By 2004 there were catalytic converters so I'd assume that oil for 2004 had
lower levels of zddp. 

 

Of course you know what they say about assumptions...

 

Thanks!

I don't see anyone speaking up Charles. (no wonder, it's pretty well
impossible to answer now) For a non-roller cam ..You want >9ppm ..Optimum is
about 12 ppm which gives you some room for depletion (which happens during
normal running) ..Folklore says >18ppm gets you into some embrittlement
issues.
(I choose to trust this one, no particular reason though)

As to what your 10W40 has in it??
2 years ago it would have had 1200 ppm. Now ?

As far as reading the designation - wtf knows what this means and this is
the API, who make up them up.
http://motorcycleinfo.calsci.com/API.html


SL 

Current 

For 2004 and older automotive engines. 


SJ 

Current 

For 2001 and older automotive engines.

 


CF 

Current 

Introduced in 1994. For off-road, indirect injected and other diesel engines
including those using fuel with over 0.5% weight sulfur. Can be used in
place of CD oils. 


Here's a blurb from Mobil pitching 0W40 and 10W40 Hi-Mileage

What would I do?
Add 600 ppm and pray a bunch.

Hi
 
 
 
Can someone who knows oil or where to look confirm that API SL/SJ/CF oil
needs zddp additive? 
 
 
 
I have additive and just bought some Mobil 10W40. (What happens if you add
too much zddp anyway? Is that a bad thing?)
