mobil 1 0w40 vs liquimoly 10w60
I did some research on some oil datasheet:
mobil1 0w40 has viscosity of 75 at 40 degree celcius vs 175 for the liquimoly 10w60. and it has 13.5 vs 24 for the liquimoly at 100 celcius.
this is a big difference,at 100 celcius ,its obvious that the 10w60 is better than 0w40,it can lubricate and cool better,but maybe at 40 degrees celcius the 0w40 is much better for the varioram,its thinner it can penetrate better in all components.just my opinion

Hey I agree that 0w40 would be a better choice out of those above 2.....But 5W40 would be better yet ....IMO....Just because 10W60 is better at high temps doesnt mean that the other is not effective enough to do the job on our motor that was engineered for a lighter weight oil....IMO...Plus that 10W60 has alot of additives because of that spread which would break down faster also..

mobil 1 0w40 has a viscosity index superior to the 5w50,if im not wrong its 185 vs 153

The higher the viscosity index the more consistent an oil's viscosity is with temperature changes.

Porsche Motorsport uses a high weight oil. Have to look it up on Monday when I get back to the shop

The concept of two plates sliding around, and oil keeping them apart is ridiculously (and dangerously) simple...yet this is how oil companies spend million$ every year- with words like 'protect' and 'increased protection'.
Paradoxically, thicker oil flows slower and has lower heat transfer rates...bearing temps can actually run hotter than lower viscosity. You want the thinnest oil that maintains a hydrodynamic layer in the bearing...no more. (What that viscosity is, for YOUR motor, I cannot say.)
Different applications IMO.
Damn oil threads....

But you said higher viscosity 'lubricates better' and 'cools better'.... neither are factual statements.

So you recommend racing oil for street use? Something without stabilizers perhaps? On racing motors that see annual rebuilds?
Different applications IMO.

One fo the best posts I have ever read in all the BS oil threads/arguments on all the forums I've been on, with what's in bold the most factual statement.

Oil types have been debated enormously over at Rennlist. Here is one thread:

10w 60 is not an oil that porsche recommends. Many have noted reduced oil consumption with 5w 50 over 0w 40.
