Deposit ChemistryWhat happens in a cylinder:

Mobilgard 560™ VS: 70 BN Equivalent Performance

• Combustion acids interact with base, detergent, dispersant in cylinder oil

• Not all additives are equal!

• Detergent and dispersant interactions

• Acid neutralisation optimised to protect engines

Mobilgard™ 560 VS Keys to Performance

With High-S HFOs:

– Enhanced Mobilgard™ 570 based technology– Optimised acid neutralisation rate– Addition of special dispersant additive – Cleanliness performance fully equivalent to

Mobilgard 570

Mobilgard 560 VS provides excellent high S protection

With Low-S HFOs:

– Balanced additive technology – Minimises deposit causing ash– Allows controlled corrosion – Excellent boundary lubrication

Meets OEM Requirements

• All field trials run at 70 BN feed rates

• MAN: Testimony Letter acknowledges successful operation at 70 BN equivalent minimum feed rates

• Wärtsilä: Follow OEM guidelines for 60 BN operation with opportunity to reduce to 70 BN equivalent feed rates
