to thin ..or not to thin ..that is the question. Whether 'tis nobler in the mind to suffer
The anxiety of oil slings like water drops.....
M1 0w-20 and PP 0w-20 appear to have a .2 cSt difference @ 100C ..if the data sheets are correct.
Typical Properties
Mobil 1 0W-20
SAE Grade 0W-20
Viscosity, ASTM D 445
cSt @ 40ºC 45.5
cSt @ 100ºC 8.6
PP 0w-20
Viscosity
@ 40°C, cSt ASTM D-445 42.6
@ 100°C, cSt ASTM D-445 8.39
Don't you think you're taking the thinner thing a bit far
However, there was this distinction in the SOPUS document ..which I'd have a hard time buying.
• Always consult your owner's manual for the correct viscosity choice and specification grade of oil required. Viscosity
recommendations often allow a range of viscosities based on local temperatures. Applications include:
SAE 0W-20 – Recommended in some hybrid vehicle applications and a limited number of low temperature
applications and some newer vehicles
SAE 5W-20 – Many current and recent OEM recommendations including many 2001 and later Ford and Honda, and
later Chrysler, Nissan and Toyota applications
Yet to look at the spec's between the 0w-20 and 5w-20:
Viscosity
@ 40°C, cSt ASTM D-445 42.6 46.84
@ 100°C, cSt ASTM D-445 8.39 8.48
Viscosity Index ASTM D-2270 175 160
Flash Point , °C ASTM D-93 224 224
Pour Point, °C ASTM D-97 -48 -45
MRV viscosity, cP (°C) ASTD D-4684 17,500 (-40) 9,700 (-35)
CCS Viscosity, cP (°C ) ASTM D-5293 4840 (-35) 4,250 (-35)
HT/HS Viscosity, cP ASTM D-4683 2.6 2.6
Noack Volatility, % ASTM D-5800 14 13.2
There's <.1 cSt between them. HTHS is identical ..and volatility is marginally different.
