Understanding OIL specs.

[EventH]

How to read these figures? (looks a Campbell's Alphanumeric soup to me )

 

API Service SL/CF

ILSAC GF-3

CCMC-G5, PD2

ACEA A1-98

 

SAE Grade 0W30 <<< this one I know :)

 

Viscosity, Kinematic

at 40 deg C, cSt 53.56

at 100 deg C, cSt 9.90

 

Viscosity, Apparent

at -30 deg C, cP 5000

 

Viscosity Index 174

 

Base Number (mgKoH/g) 8.0

 

Sulphated Ash, (% wt) 0.73

 

Specific Gravity, 15/15 deg C 0.868

looks lousy to me

[Freemen]

Think our Guru Genie47 can answer that !!

 

Peace Bro

[EventH]

ommmmmm.... waiting for the Guru of Oil

API SL/CF: means can use in todays modern cars though the standard has just been superceded by SM.

ILSAC GF3: Fuel economy oil but superceded by GF4 recently.

ACEA A1-98: This oil is not going to last past 10k when traveling 70% highway. Less than 70% highway, change at 5k intervals.

Viscosity at 100 deg C @9.9cSt: A solid SAE30 oil at 100 deg C. Now the problem is will it keep at 9.9cSt after 5k?

Viscosity Index: or VI looks OK but if you can show me the HTHS, it is a much better indicator of how long the oil can last.

Base Number: or TBN at 8.0 which shows this oil to be a normal PCMO. The question now is what is the TBN after 10k? Most oils will have 3.0 if they cover at least 70% highway.

 

The rest not important.

thanks ... I guess Mobil 1 is still better than SPC SYNACE Max.

[Furrynadz]

for spc only good one are the SL and SM rated synace oils and one or two of the diesel ones

[Garlic]

Went tru' some threads in BITOG and some of the gurus there says SL has a better addictive package as compared to SM?

[Genie47]

Yes it is true. SL has better additives. SM has better base oil. Most manufacturers' SM oil are blended.

[Furrynadz]

so u rather take SM or SL

 

SM sounds kinky

[Genie47]

I would still like SL. Some BITOGers think SM is suicidal.

So, what is the min HTHS number requirement for the best engine protection in our climate..??

Bro sorrie to dig up such a old thread. Would like to ask u an oil with higher Vis @ 100 deg C value signifies wad?

 

And is higher e VI e better or vice versa?

 

Me looking @ Redline 5w30 and 10w30.
