NEW Mobil 1 5w-20 EP specs

[buster]

http://www.mobil.com/USA-English/Lubes/PDS/GLXXENPVLMOMobil_1_Extended_Performance.asp

@40c - 47.4
@100c - 8.9
VI - 171 ***
HT/HS - 2.7
PP - -51C (-60F)
FP - 455F
TBN - 12+ (?)

Looks great on paper. TBN is probably 12+ VI is very high. (VII's?) I wish they published Noak, that would tell us something more about the base oil.

No CCS, cP (ASTM D-5293) spec.

I wish they would post the specs for their new HM oils. Those slow-pokes. They must be too busy counting their money.

Viscosity numbers are 47.4 @40c and 8.9 @100c

 

[Lonnie]

Do these specs make it a better oil than other 5w-20's? Are there not some more specs like how quick does it evaporate?

Compare to Amsoil 0w20. Given the unknowns it'll be interesting to see which performs better in actual use.

Can someone explain to me the viscosity index and the flash point? Also, the Mobil 1 5w-20 appears to be thinner when cold so how is it a 5w while the Amsoil is a 0w?

The Xw does not mean it is that thin when cold. It passes a test, that is taken at certain X temperature and if the X cP numbers are in a certain range, it determines the Xw rating.

I would definitely like to see this oil go head to head against Amsoil.

I think you should run Amsoil 0w-20 in the Ford and M1 5w-20 EP in the Honda.

I'm putting the Amsoil Eao oil filter on tomorrow. I have 2 of them for my car. For the Honda 2.4L, you can use any oil. The Amsoil 0w-20 would work very well as would the EP. I want to try the Havoline at some point again.

Huh? How did you come up with that conclusion?

 

[The Critic]

I meant that buster should experiment for fun (and try both), now that he owns two vehicles that recommend 5W20.

 

[TeeDub]

The only "spec" that matters is how well the oil works in actual service.

The best predictor of how well the Mobil 1, 5w-20 is going to work is the performance of their 5w30 and 10w30, API/SM rated oils in recent UOA's....

If I was formulating a 0w-20 synthetic, I'd use the performance of the Redline 5w-20 as the "benchmark" for wear protection, oil consumption, deposit control, etc....

FWIW, I wouldn't be surprised if the Amsoil 0w-20 and the Mobil 1, 5w-20 were both using the same 4 cst, "SpectraSyn Plus", low viscosity PAO basestock.
