Aggressive Transport’s Fleet Manager, Anthony Ritter is always looking for improvement. He noticed that his vehicles were spending too much time off the road due to engine oil changes which was costing the business money.

Ritter calculated that each oil change was costing the business $400 when he combined the labor cost, filter, the oil itself and the time taken for the change. Roll that out across the fleet and a round of oil changes was costing $19,200.

The data showed that Aggressive Transport’s Detroit Diesel and PACCAR engines required new oil every 30,000 miles. Ritter saw room for improvement and, understanding the financial savings this could bring, wanted to extend drain intervals and reduce oil consumption among the fleet.

Aggressive Transport took this request to Valley Pacific Petroleum Service, a long-standing local Authorized Distributor of Petro-Canada Lubricants (PCL), an HF Sinclair brand. Knowing the PCL products well, Valley Pacific saw an opportunity to put them to the test through the DURON Challenge.

PCL wants to prove that DURON heavy-duty engine oils can help provide more reliability, longer drain intervals and lower fuel costs. By taking a DURON Challenge, PCL assesses how DURON can improve an operation, provides DURON engine oil for the challenge at no cost and has used oil analysis completed on oil samples to demonstrate its impact.

Greg Fee, Territory Manager at Valley Pacific worked with his PCL Technical Service Advisor to present a compelling offer, including two products to address both of Aggressive Transport’s goals: extending drain intervals and increasing fuel economy.

Having undertaken the DURON Challenge, Aggressive Transport experienced exceptional results:

• Extended oil drain intervals

Starting at 30,000 miles per oil drain, intervals were gradually extended through to 40,000 miles. This was done safely thanks to the technical knowledge of Valley Pacific and PCL’s expertise, with thorough oil sampling to produce a nice improvement for each truck.




Over the Challenge period, this equated to $76,800 savings purely achieved from extending drain intervals*, a significant impact for the business.

• Improved Fuel Economy

Additionally, using in-truck telematics, the results demonstrated a 0.5 miles per gallon improvement fleetwide. This equates to a 1% improvement in fuel economy, meaning that Aggressive Transport saved $5,616 on fuel per truck and $269,568 across the full 48-vehicle fleet.




Based on the fantastic results and excellent service, the partnership between Aggressive Transport, Valley Pacific and PCL continues to be successful and deliver results. Aggressive Transport decided to switch its entire fleet to DURON SHP 10W-30 and is confident that, with the help of its partners, the company can continue to operate reliably and efficiently.
