Every one that buys from NAPA be sure it is the new oil that has for hybrids on the bottle and not the old discontinued version that has meets Honda and Ford specs. or something like that. http://www.imakenews.com/lng/e_article000082247.cfm So - This indicates (to me) that the GF-4 rating is for a lubricant that may not has as good of a high pressure lubricant as it's predecessor GF-3. That said - lower phosphorus will mean lower phosphorus emissions. At what cost? BTW - They're working on GF-5 now... For me - I'll take the higher emissions in exchange for less wear if the option is there.. (putting on nomex long-johns) - Let the flames begin... :) |
