		just FYI check www.mustangworks.com, in their tech articles, drivetrain section, they've got a great article not only comparing major brand oils but also explaining tech & terms.  Some surprising differences in lubricating ability between some brands, especially where ability to work in heat without breaking down is concerned.  Synthetics like Mobil 1 the best protection for reasons they explain in article.
  They do say that multi-grade ability comes from additives and that 10W40 has more of those to make the "stretch" - the more the less durable the oil - so that 10W40 is  not as durable an oil as 10W30, and they advise against  using it for that reason.    |
