Diesel Oil Change in Phoenix

Sun Devil Auto’s diesel oil change with Shell Rotella (SAE 15W-40) offers several benefits to your diesel vehicle. Diesel engine oil is required to do a lot more than a conventional motor oil such as running longer distances and hauling heavier loads. You can trust that Shell Rotella oil will protect your engine under all types of driving conditions, regardless of the age of your vehicle.

Shell Rotella triple protection provides vital care to your diesel engine by controlling three critical areas:

Deposit Control-keeps the engine clean, prevents oil “sludge” allowing your vehicle to run at its peak performance for an extended life.

Acid Control – protects against corrosion caused by burning fuel as oil ages.

Wear Control – lubricates moving metal engine parts to prolong the life of the engine.

You may ask, “How often should I change my diesel oil?” The more often you change your oil in any vehicle, the longer your vehicle will last. In fact, not changing your diesel engine oil on schedule can result in a non-start condition. How does this occur? You see, oil is used as a hydraulic fluid to run the fuel injector pump on most diesel engines. Additives in diesel oil, such as Anti-foaming agents are necessary to extend system life and improve reliability. The high pressure of the pump can cause the oil to aerate and foam, causing it to lose its hydraulic properties. In most hydraulic systems, fast and turbulent fluid flow can lead to foaming.

Anti-foaming agents are additives that reduce the form of bubbles and allow those that do to dissipate quicker.

Vehicle manufacturers’ recommendations for oil changes vary based on mileage and your driving habits. Shorter distances around town will cause diesel engines to accumulate contaminants requiring more frequent oil changes. We recommend checking your vehicle’s oil level every few weeks and especially before any long journey. Stop into any Sun Devil Auto to review your vehicle’s recommended oil change and maintenance schedule with your trusted Service Advisor.
