Delo® 400 NG SAE 15W-40 Growth in Natural Gas for Vehicle ApplicationsGrowth in Natural Gas for Vehicle Applications

Mobile natural gas continues to grow in popularity in over-the-road applications

CNG and LNG Fuels have favorable low “carbon intensity” compared to diesel

Centralized Vehicle/Fueling Applications− Increased usage in ports, waste companies, LTL trucking,

Vocational trucking, and airports to reduce Particulate Matter− Roundtrip Local Fleets converting to CNG/LNG vehicles – savings

plus green sustainabilityplus green sustainability

LNG preferred for long-haul applications – allows for flexible fuel ingoptions for trucks on the roadoptions for trucks on the road

CNG/LNG trucks typically cost more than conventional trucks, but quick ROI is achieved from reduced fuel cost

Delo® 400 NG SAE 15W-40Republic Waste Field Trial with Cummins ISL-G Engines –C i ISL G B i St tCummins ISL G Bearing Structure

• Cummins ISL G engines uses a tri-metal bearing – Tin Flash, Lead, Copper ,Steel base

• The tin “flash layer” is designed to wear off during engine break-in to allow appropriate bearing seatingThe tin flash layer is designed to wear off during engine break in to allow appropriate bearing seating

• The lead layer is designed to be wear away slowly to provide a softer surface for longer engine performance For used oil analysis – lead wear will come typically from the bearings

• At some point, the lead layer will give way to a copper under-layer which indicates the bearing is wearing out and the engine bearings changed - for older engines High copper in used oil analysis typically indicates bearing wear (60-200ppm) High copper in newer engines is typically due to copper oil cooler being passivated (100-700ppm) After the passivation period in new engines – the copper level in used oil analysis should fall below 30ppm

Delo® 400 NG SAE 15W-40Republic Waste Field Trial with Cummins ISL-G Engines - SummaryRepublic Waste Field Trial with Cummins ISL-G Engines - Summary

Delo 400 NG SAE 15W-40– Viscosity staying in grade showing excellent shear stability and

performance of the oil

– Providing excellent wear metals control even out past 600 hours of oilProviding excellent wear metals control even out past 600 hours of oil drain intervals Copper Wear rates are high – but expected for new engines as copper oil cooler is passivated

Based on low lead wear rates – none of the copper is coming from bearing wear

– Delo 400 NG providing very good acid control even past 600 hours of operation

– Republic Waste pleased with first part of the field testing program –Republic Waste pleased with first part of the field testing program looking to develop next target of 750 hour oil drain intervals starting in 2013.

– Republic Waste Planning to add more CNG trucks for the future.
