Yarbs Grading and Paving is a public works contractor headquartered in Fresno, California. They specialize in asphalt paving and overlays, mass excavation and demolition. Prior to using Chevron Delo® 600 ADF they were constantly experiencing warning lights, particularly on their rollers, indicating that a regeneration was required.
Operators, under pressure to keep projects moving, would bypass the regen. You can only do this so many times before a forced or manual regen is required. When this happens, the equipment is down for 45 minutes leading to costly downtime and excess fuel consumption to complete the regen.
Since making the switch to Chevron Delo 600 ADF over a year ago, warning lights and manual regens are virtually non-existent. Active regens have been reduced by more than 50% and regen cycles have been shortened. This translates to less fuel burned and no worries about downtime related to regen issues. Moreover, they have not had to clean or change out a DPF.
Because of their positive experience, Yarbs Grading has begun recommending Chevron Delo 600 ADF to their subcontractors. Chevron Delo 600 ADF delivers maximum system protection to both the engine and emissions system.
