Why Diesel Engines Need Premium Oil Changes in Northern Colorado

Diesel engines work harder than gas ones, especially in our local environment:

• High soot and contamination from dusty gravel roads in Weld County and rural areas like Ault and Pierce.

• Extreme cold starts during Greeley winters that stress older oil.

• Heavy-duty use for oil field rigs, construction equipment, farming tractors, and light-duty pickups in Windsor, Severance, and Timnath.

Skipping or using low-quality oil leads to sludge buildup, reduced fuel efficiency, and costly repairs. That's why we exclusively use Chevron Delo 400 XSP full synthetic diesel oil—formulated for superior protection:

• Extended drain intervals for fleets and high-mileage drivers.

• Excellent wear protection in extreme conditions.

• Superior soot control and cleanliness for longer engine life.

• Proven performance in modern emissions-equipped diesels (like Duramax, Powerstroke, and Cummins).

We also carry synthetic blend options and replace fuel/air filters on-site to keep your diesel running strong.
