One issue I found with the article is omission of the API shear factor information,the oils ability to resist shear is what protects cylinder walls,not some hoo hah about oil burning..Shear is a measurement of the oils ability to lubricate in thin film high load applications,Like diesel engine cylinder walls and flat tappet engines..ZDDP comments are the talk of snake oil salesmen,the guys who sell the high dollar custom oils, they revel in the zinc issue....ask them to show actual failure directly attributable to a lack of zinc and the bullshit goes into high gear,they like to question your intelligence,how dare you question this well believed bullshit story about flat tappets and zinc and why you have to buy the 30 bucks a quart miracle they hustle..the bullshit detector went off when they cited AMS oil..BTW,they also cite Les Andrews..a fine man,a member of my club and a top notch technical writer,but no petroleum engineer.
