The Most Common, and Most Critical Maintenance Service

Oil changes may be the most familiar vehicle service, but they’re also one of the most important. Regular oil service keeps your engine properly lubricated, protected, and operating as designed. Skipping or delaying oil changes increases friction and heat inside the engine, which can eventually lead to major failures such as engine rebuilds or replacements—repairs that are both costly and avoidable.

Simply put, engine oil lubricates moving parts, helps control temperature, and shields internal components from excessive wear, allowing your engine to perform reliably mile after mile.

Why Regular Oil Changes Matter

Proper Lubrication
Fresh oil creates a protective barrier between metal components, preventing grinding and premature wear.

Temperature Control
Oil helps carry heat away from engine parts that generate friction during operation.

Cleaner Engine Operation
Oil traps dirt, debris, and sludge, keeping contaminants from circulating through the engine.

Improved Performance and Efficiency
Clean oil reduces resistance, helping your engine run smoother and improving fuel economy.

Extended Engine Life
Consistent oil maintenance helps prevent long-term damage and maximizes engine longevity.

How Often Should Oil Be Changed?

Oil change intervals vary depending on oil type, vehicle design, & driving habits:

Conventional Oil: Every 3,000–5,000 miles or 3–6 months

Full Synthetic Oil: Every 7,500–10,000 miles or 6–12 months
