Good day
lets see if some people can think past their nosses
if a manufacturer, specifies a specific oil for a particular application, then don't ne a smart ass, and think that you better then the yanks or the Germans (yes they are leaders in Lubrication)
so will be a little more specific on here
have seen on some of the local forums "open sarcasm" the very clever ones, with very clever people "close sarcasm" where advice was given to a member about oil for a jeep 4.7, and the reply were scary, jeep is one of those manufactures that has very specific oil requirements
use the wrong oil and you will pay the price
so before taking advice from the local clown forum, rather do your homework
use what the book say when doubt
remember the Germans and the Americans are the leaders in lubrication
