*LR777,
how can you say that the test is obsolete? So you mean to say that the oils that were tested are obsolete? The oils that were tested are still in the market right now, and still have the same formulation right now and 5-7 years ago.

Well, if you read the article you posted comprehensively...the highest rating given for the gasoline category is SL which was first given out 2004 but still in current circulation right now, which I can understand because theres not much difference or should I say theres No new revolutionizing technology that has higher lubricating requirements unlike with the commonrail technology in the diesel engine scene. infact its only difference with the highest rated oil today for gas engines which is the SM is that it has

improved oxidation resistance, improved deposit protection, better wear protection, and better low-temperature performance

also introduced in the same year 2004....and for the diesel category, its CF2 which is labeled obsolete by the API and which is said to only be suitable for two stroke engines as indicated here---->http://www.api.org/certifications/en..._March2010.pdf which I already posted above....

and if your asking if I think the oils in that article you posted is obsolete,
I want to expound on that....YES I do and I do not...

I do not, because for the gasoline engine oil category most of the oils in that article is still in current production and sale....within the SL and SJ certification...

and I do, because with regards to the diesel engine category none of it even meets the lowest certification today which is CH-4 and worse, it is even two levels behind it...

Now, if you are wondering why you can still see the same oil brands and grades in the market, because they have REFORMULATED those oils to comply with modern engine demands especially on diesel engines and to the API certification and licensing system....So technically it is not right to say that the current oils that is on sale today from those brands has the same formulation way back when that article was published...

just received a reply from my uncle based in california who works for a heavy construction company there, and they have very favorable comments on the mobil1 heavy duty turbo diesel truck oil. they are currently in the process of disposing of their old castrol oil stocks and wswitching to the mobil1 brand. take note that they are also going to use this particular oil on their heavy machineries. so this is a very good news well for me, as far as i am concerned.... hehehehehe

ninong arvs, ask ko lang, san sa california yung uncle mo? dun ba sa mainit or malamig na part? hehehe
