Hi,
I bought a 208 l barrel of Mobil Delvac XHP 10W40. The oil has been sealed hermetically in the barrel for 5 years so I was afraid that maybe the oil could not be used anymore.
The oil analysis was made in a German lab why the results look different. Also note that the test report contains properties usually not seen in the common reports posted here (Sulphur for instance)
Here are the results:
WEAR:
Iron [mg/kg] 0
Chromium [mg/kg] 0
Tin [mg/kg] 0
Aluminum [mg/kg] 0
Nickel [mg/kg] 0
Copper [mg/kg] 0
Lead [mg/kg] 0
PQ Index (particle quantifier) OK
CONTAMINATION
Si [mg/kg] 4
K [mg/kg] 1
Na [mg/kg] 16
Water [%] Diesel oil [%] Bio diesel oil [%] Soot [%]
OIL CONDITION
Viscosity @ 40 degC [mm2/s] 85.23
Viscosity @ 100 degC [mm2/s] 13.60
Viscosity index 163
Oxidation [A/cm] 5
Nitration [A/cm] 0
Sulfation [A/cm] 0
Ability to absorb dirt [%] 100
ADDITIVES
Ca [mg/kg] 4303
Mg [mg/kg] 34
B [mg/kg] 294
Zn [mg/kg] 1120
P [mg/kg] 997
Ba [mg/kg] 0
Mo [mg/kg] 0
S [mg/kg] 4252
ADDITIONAL TESTS
BN, base number [mgKOH/g] 17.91
AN, acid number [mhKOH/g] 3.74
Questions:
1. How do I read the additive (Ca, Mg etc) results? What is good what is bad?
2. How do I read oxidation, nitration and sulaftion results? What is good what is bad?
3. How do I read Si, K and Na results? What is good what is bad?
The oil is mainly intended to be used in a Japanese Toyota with a naturally aspirated 4,2 liter inline 6 cyl diesel engine. The reason for writing this is this post where it is discussed how piston crowns on japanese engines are different from European and US engines. Any comments?
4. It is safe to use this oil in the above mentioned Toyota engine?
5. Can this oil also be used in both gasoline and diesel passenger cars (non heavy duty)?
Thanks in advance,
Lucas
