• Piston liner crosshatch is clearly visible – showing protection of Delo 400

• Good Crosshatching indicates excellent lubrication film is maintained and providing excellent component protection

• Retention of the crosshatching ensures good oil consumption control also for the engine helping to reduce top-off and also blow-by that can reduce power

• A&A concrete has used a “one drum” approach to lubricating their manual transmissions and axles.

• They have used Delo Gear Lubricant ESI SAE 80W-90 for both components and have found it has provided superb protection and equipment life at a reduced cost to more expensive synthetics.

• Shown below are recent teardown pictures showing both components after 750k+ miles on Delo Gear Lubricant ESI SAE 80W-90 – both components were in such good shape they could be reused.

• By using the “one drum” approach – A&A has saved over $160,000 versus buying synthetic top off for the last 10+ years – additionally by using the 1 drum approach they have reduced lubricant complexity

A&A ConcreteCement Mixer Truck – Axle Performance

• A&A Concrete has seen excellent load carrying performance in their axles using Delo Gear Lubricant ESI SAE 80W-90

• The borate technology in Delo Gear Lubricant ESI allows for use of a mineral based product at a lower cost than traditionally more expensive full synthetic SAE 75W-90 gear oils used in these axles.

• Shown below are the teardown pictures of the A&A Cement truck axle showing excellent gear teeth protection using Delo Gear Lubricant ESI SAE 80W-90.


Delo Family Products have provided excellent cement truck longevity

A&A Concrete has seen minimized operating cost performance by using the full Family of Delo products

No need for expensive synthetics to achieve equipment durability, extended drains or business reliability.
