a 5w50 wouldnt that require huge ammount of vii?
i dont know if even a synthetic could manage that without a bunch of vii floating around.....

I converted A dollars to US dollars, pretty expensive down under, $A50 is about $32.89 here. $A80 would be about $52.63.quote:
M1 5w-50 here in OZ is about $A50 for a 5 litres container, the M1 0w-40 is about $A80 for 6 litres in 1 litre packs
Delvac 1 is about $A10 per litre in bulk
Dr. T, how do you know this? Lets see some proof. Have you done any studies on this? Most engines if taken care of will last for hundreds of thousands of miles on a 30wt. I know this because I along with many other people have achieved this. I myself got 300k out of an 87 Corolla using the cheapest oil available. Mobil's million mile test was using a 30wt oil....what was wrong with that?quote:
Engines ARE NOT "made for" a certain viscosity. It's all B.S.. U.S. cars are spec'd for 5-30 in general so that:
I agree with you. I think Mobil does a poor job with product data sheets. Sometimes the numbers are different for the same oil. Mobil does cater to the API and fuel efficiency requirments so European oils in general will meet higher specs. I think the 5.1 is right, mainly because they are using a less volatile base oil I imagine plus there is only a 25pt spread for a 15w-50. I don't think Mobil uses anything more advanced then Amsoil or Redline in terms of additive packages go.quote:
Oh I have confidence in the numbers per se....I just don't think they're applicable to the "supposedly same" oil sold in other continents with different playing fields. Let's put it this way, if I was in Europe I would not be using "U.S.-sourced" M-1 with all the other great European oils out there....that is why they make different products for different markets.
