The source of the data I quote is from pqiadata.org.
I was stunned to see the reduced amount of ZDDP in some of the HDEO's that I have held in high esteem in the past. For instance.....
Delo 400
Zn - 817
P - 779
Delvac 1300
Zn - 884
P - 804
(Both have added Mg and B)
But Rotella and Valvoline and SuperTech, all keep their Zn and P between 1000 and 1199, for a much stouter ZDDP level.
I have read several threads with folks upset over this new generation HDEO and debating whether it is protecting as it should. But for the purpose of posting here, I really want to know everyone's opinions regarding motorcycle engines.
I would also like to know everyone's opinion of a product like ZDDPlus. If one were a die-hard Delvac fan, could a little ZDDPlus be added, bringing the levels back up to the 1200-1500's and rest assured?
I for one have after-market cans on my bikes, without a complicated exhaust system and am not worried about CAT failure, etc.
The newest bike I own is also a 2005 (I've got 7 bikes, 1997-2005) I use to be on the 'synthetic-only band wagon', but in the last couple of years have fed all my machines HDEO.
