REQUIREMENTS AND OIL QUALITY
SYSTEM OIL REQUIREMENTS AND QUALITY FOR WÄRTSILÄ
®
34SG
ENGINES
Viscosity
Viscosity class SAE 40
Viscosity Index (VI)
Min. 95
Alkalinity (BN)
Lubricating oils with BN of 4-7 mg KOH/g have to be used.
Sulphated ash level
The content of sulphated ash in gas engine lubricating oils is a very important property. Too
high ash content can cause preignition, knocking and spark plug fouling, while too low ash
content can lead to increased valve wear. Low ash lubricating oils with sulphated ash level
of max. 0.6 % w/w have to be used.
Additives
The oils should contain additives that give good oxidation stability, corrosion protection,
load carrying capacity, neutralisation of acid combustion and oxidation residues and should
prevent deposit formation on internal engine parts.
Foaming characteristics
Fresh lubricating oil should meet the following limits for foaming tendency and stability,
according to the ASTM D 892-92 test method:
Sequence I:
100/0 ml
Sequence II:
100/0 ml
Sequence III:
100/0 ml
Base oils
Use of virgin base stocks is only allowed, i.e. recycled or re-refined base oils are not
allowed.
