Recommendations for Cylinder Oil Feed Rate and
Cylinder Oil Quality for VT2BF, K-EF, K/L-GF, K/L-
GFC/GFCA, L-GB/GBE Engines

Dear Sirs,

The following recommendations, which supersede recommendations given in
Service Letters No. 81-161 of March 1981 and No. 83-196 of October 1983,
are valid for engines installed in ships with controllable pitch and fixed
pitch propellers as well as for stationary engines.

Based on more recent service experience, our general recommendation can be
summarized as follows:

Specific cyl. oil feed rate:

VT2BF = 0.5 - 0.75 0.75 g / BHPh or 0.7 - 1.0 g / kWh
K-EF = ” ” or ” ”
K-GF = ” ” or ” ”
L-GF = ” ” or ” ”
K-GFC = ” ” or ” ”
L-GFC = ” ” or ” ”
K-GFCA = 0.6 - 0.9 g / BHPh or 0.8 - 1.2 g / kWh
L-GFCA = ” ” or ” ”
L-GB/GBE = 0.6 - 0.9 g / BHPh or 0.8 - 1.2 g / kWh

These figures are valid for catalogue MCR, i.e. catalogue output and for engines which have been
run-in.

Fig. 1 states the corresponding nominal feed rates in kg/cyl. per 24 hours for all the above engines on
the basis of the catalogue MCR of the engines.
