Applications - Kohler SFGLD480 Operation & Maintenance Manual

1. INTRODUCTION
There are currently no standard procedures for classifying lube oils to be used in gas-fuelled and ethanol-fuelled
engines. It is therefore necessary to perform exhaustive field tests in order to approve a suitable lubricant. Along
with the ash content, there are several other parameters to bear in mind. These include phosphorus content,
resistance to oxidation and nitration (often produced by the high working temperatures), neutralising capacity
and corrosion inhibition (particularly in the presence of aggressive gases).
2. DESCRIPTION
KOHLER MOTOROIL 3040 PLUS is a lubricant designed by Kohler division in collaboration with the most
prestigious lubricant manufacturers. It has been specially formulated for use in Kohler engines that
operate on gas or ethanol.
KOHLER MOTOROIL 3040 PLUS is a high-performance oil with a medium ash content. It is formulated with
prime quality paraffin bases that provide it with exceptional oxidation and nitration stability, great
thermal resistance, and a very low tendency to carbon deposit and residue build-up. Maintaining excellent
performance after a long period of operation is thus ensured. Additionally, this oil has a low foam-forming
tendency, good emulsibility and corrosion protection for cylinders and bearings, while considerably
reducing wear on piston rings, liners and valve seats. All this means the oil has a long service life and
filters withstand extended maintenance intervals.
Given its advanced formulation, KOHLER MOTOROIL 3040 PLUS is specially suitable for modern four-stroke
engines with low oil consumption. It has been specially developed to ensure extended intervals between
oil changes in engines whose usability is limited by the oil lifespan.
Its detergency and dispersancy system controls the build-up of carbon deposits and sludge, which results
in cleaner engines, longer lasting oils and lower filter costs.
This oil has also been designed to provide exceptional protection against piston abrasion and wear of
cylinder liners and piston rings.

3. APPLICATIONS

KOHLER MOTOROIL 3040 PLUS has been specially designed and is recommended for providing the highest
performance in Kohler engines that operate on natural gas and ethanol. It can however be used in all kinds of
naturally-aspirated or supercharged four-stroke engines, whether high or medium rated, that require a
lubricant having a medium ash content. It is designed to ensure optimum engine life and lower maintenance
costs. Its scope of application encompasses stoichiometric combustion and lean-burn engines as well,
ensuring low oil consumption in both cases.
Given its low zinc and phosphorus content, this lube oil can be used in engines fitted with a catalytic
converter, which require lube oil having a medium ash content.
Its advanced technology means any wear on the valve train components can be monitored as well as
reducing the risk of abrasion, scoring and accelerated wear of pistons and piston rings. The end result
means lower engine operating and maintenance costs.
