General Truck Maintenance & Preventative Service
The single most important factor in your truck’s longevity is consistent, high-quality preventative maintenance. At Performance Authority in Bend, we provide expert truck maintenance services designed to protect your investment, improve reliability, and help you avoid expensive, unexpected repairs down the road. Think of it as the cheapest insurance policy you can buy for your truck.
Expert Diesel Oil Changes: The Performance Authority Difference
An oil change isn’t “just an oil change,” especially for a diesel engine. Quick-lube shops use a one-size-fits-all approach that is simply wrong for your complex diesel engine. They use bulk, generic-grade oil and cheap filters that can lead to premature wear and costly damage. At Performance Authority, our expert diesel oil changes are different.
- We Use The Highest Quality Oil: We use top-tier, heavy-duty diesel oils, like Schaeffer’s, that meet or exceed the specific requirements for your Powerstroke, Cummins, or Duramax engine.
- We Use High-Quality Filters: We use OEM or equivalent high-quality oil and fuel filters designed to handle the high pressures and filtration demands of a diesel engine.
- We Perform a Professional Inspection: Our trained technicians perform a thorough inspection during every service to identify potential issues before they become major problems.
Don’t trust your multi-thousand-dollar engine to a $50 quick-lube special. Get it done right at our truck shop in Bend, OR.
