I know there has been numorous discussions in this forum regarding Shell/Rotella as well as several other brands of motor oil with Zinc and Phosphorous content. I received my September issue of TW today and on page 62 there is an advertisement for Motorhead Hi-Z Motor Oil it says that it has approximately 55% Zinc and 45% Phosphorous according to the adv. Shell/Rotella has 0.14% Zinc and 0.13% Phosphorous. Has anyone here had any experiance with the Motorhead oil and/or heard any pros or cons ? Apparently this is a new vendor in TW, as I haven't seen this adv before.
