For drivers with vehicles reaching the high-mileage milestone—typically over 100,000 kilometers—proper maintenance is crucial to ensuring longevity and performance. One of the most important aspects of high-mileage engine care is routine oil changes. This guide will walk you through the essentials of maintaining an aging engine, helping you get the most out of your vehicle.
Why High-Mileage Oil Matters
Over time, engines experience wear and tear, leading to increased friction, sludge buildup, and potential leaks. High-mileage oil is specially formulated to combat these issues with:
- Seal Conditioners – Helps reduce leaks by rejuvenating aging engine seals.
- Detergents – Cleans sludge and deposits from internal components.
- Viscosity Enhancers – Maintains proper lubrication despite engine wear.
Choosing the right high-mileage oil can significantly extend the lifespan of your vehicle while improving fuel efficiency and performance.
Signs Your Engine Needs a High-Mileage Oil Change
If your vehicle has high mileage, pay attention to these warning signs:
- Oil Leaks – Puddles under your car indicate worn-out seals.
- Increased Exhaust Smoke – Blue or gray smoke may signal oil burning.
- Engine Noise – Knocking or ticking sounds suggest oil breakdown.
- Poor Fuel Economy – Dirty oil increases engine friction, reducing efficiency.
- Check Engine Light – A visit to an Engine Diagnostics North Vancouver specialist can determine if your oil is the culprit.
Best Oil Change Practices for High-Mileage Vehicles
- Use the Right Oil – Choose a high-mileage synthetic blend or full synthetic oil that meets your vehicle’s specifications.
- Replace the Oil Filter – A clogged filter can reduce lubrication efficiency.
- Check for Leaks – Inspect the engine bay and undercarriage for leaks.
- Monitor Oil Levels Regularly – Older engines may consume more oil over time.
- Follow Manufacturer’s Change Intervals – Typically every 5,000 to 8,000 kilometers for high-mileage vehicles.
DIY vs. Professional Oil Change
While a DIY oil change is possible, taking your vehicle to a Automotive Repair North Vancouver expert ensures proper disposal of old oil and professional inspection for additional wear or issues. Mechanics can also perform:
