"Here is VOA info I found on Royal Purple API (SL) Rated 5W-20 motor oil.

Zinc: 666ppm
Phosphorous: 563

CompSyn"

That looks more like an SM level than SL. I still wonder who else is playing those kind of games.

In the last year I have found about 60 qts of left over older formula SJ and SL at various stores.

So tonite I was in a Walmart checking the back of the shelves. I noticed they carry Royal Purple, it has a SL rating. The Mobil 1 'High Mileage' oil also has a SL rating, not SM like other Mobil 1 formulas. Anyone know the Zn-Ph ppm of these two?

I prefer not to run diesel oil because of too much detergent and the racing oil has too little, requiring more frequent oil changes. Something I can get locally off the shelf would be great if High Mileage Mobil 1 has enough ZDDP.

The straight 30wt Castrol also has a SL rating, other 30wt oils I have seen in the past is still SL oil.




Mobil 1 10-40 High Mileage, SL/CF rated:

PHOSPHOROUS: 860
ZINC: 1035

I’ll keep looking for a up to date UOA/VOA for Royal Purple

BTW, check out the New AMSOIL Group Discount for moparts.com members.





Thanks CompSyn .
The Mobil 1 HM doesn't look too bad, better than the other SM oils. Guess it would do in a jam but I'll find a local Amsoil dealer when my older SJ and SL oil supply is gone.
Royal Purple , appears they need to upgrade their labels to SM.


I keep seeing GM EOS has been re-released, only with another part #.
Whats the new # and is it still ZDDP or has it been changed to Moly?

I found the new EOS.
http://www.gmpartsdirect.com/results.cfm?singlepart=1&partnumber=EOS
I suspect it's not the same as it is labeled 'engine assembly lubricant'. Possibly it's Moly and not ZDDP. It's also twice the cost of what Hughes offers.

Does it take just one bottle of the EOS per oil change?
