Oil, Filters, and Fluid Services in Lac La Biche, AB
Engine oil, transmission fluid, coolant, and differential oil all play a vital role in preventing wear, controlling temperature, and keeping your systems running smoothly. At Ethos Mechanical, we offer full-service oil and fluid changes for heavy-duty, medium-duty, and light-duty diesel vehicles. Our services include:
- Engine Oil and Filter Change – Routine oil changes protect your engine from heat, sludge buildup, and premature wear. We use high-quality synthetic or conventional oil to match your engine’s requirements.
- Transmission Fluid Change – Fresh transmission fluid prevents slipping, overheating, and hard shifts. We replace worn fluid and filters to keep your drivetrain responsive and smooth.
- Coolant Flush and Refill – Coolant degrades over time and loses its ability to regulate engine temperature. We flush contaminated fluid and refill with the correct coolant for your engine spec.
- Differential and Axle Fluid Replacement – Gear oil changes are essential for preventing metal-to-metal contact and extending the life of your axle components.
- Hydraulic Fluid Service – For vehicles with hydraulic systems, we provide full fluid replacements and filter changes to keep equipment operating reliably.

FAQs
How Often Should I Change My Truck’s Oil?
Typically, this is every 250 to 500 hours and is dependent on the service industry and load put on the engine and auxiliary equipment.
What Happens If You Don’t Change the Oil in Your Truck?
Old, dirty oil loses its ability to lubricate and cool engine components. This leads to overheating, sludge buildup, increased wear, and eventually engine failure. Routine oil changes are essential for engine longevity.
