A Fleet Manager’s Guide to Choosing the Right Engine Oil

As a fleet manager, you’ve got enough on your plate, dealing with delivery schedules, compliance, driver needs, and of course, keeping every vehicle in your fleet in peak condition.

Let’s be honest—choosing the right engine oil is another task on top of all the things you’re already juggling. But don’t worry! We’ve got you covered. At Millers Oils, we’re making it easy to pick the perfect engine oils for your HGVs without the hassle, keeping your fleet running smoothly, efficiently, and most importantly­, on budget.

Why Choosing the Right Oil Matters

HGVs aren’t your everyday vehicles—they’re built to run long hours, carry heavy loads, and handle more stress, they need a specialised oil that can take the heat:

• High Oxidation Resistance: With engines running hot, you’ll want oil that won’t break down under high temperatures.
• Durability Under Heavy Loads: HGV engines put oil through its paces, so you need one that stands up to arduous conditions. Without proper lubrication, friction between engine components can lead to erosion and accelerated wear.
• Extended Lifespan: HGVs put engine oil through more wear and tear, so oils need to handle higher temperatures and tougher conditions than regular vehicle oils.

In short, the right oil means better performance, fewer repair bills, and a longer lifespan for your engines. Choose the wrong oil, and you’re looking at reduced fuel efficiency, increased emissions, and more unscheduled stops than your delivery schedule can handle.

Key Considerations When Choosing Engine Oil for HGVs

Think of Oil as a Component, Not a Commodity

Oil isn’t just a fluid top-up; it’s an essential component of your engine. Engine oils like Millers Oils Truckmaster range are formulated specifically for HGVs to ensure compatibility and reliability.

Follow Manufacturer Specs and Standards

Not all lubricants are equal. Sticking to Original Equipment Manufacturer (OEM) recommendations and industry specifications means you’re choosing an oil that meets the standards for your engines based on stringent manufacturer testing.

Match Oil to Vehicle Use

HGV fleets don’t all have the same workload. Some vehicles are on long motorway hauls, others on urban routes with frequent stops, and the load they carry varies too. Different driving conditions and loads place unique demands on your oil, so pick one designed to handle the type of work your fleet does.

Adjust Drain Intervals Based on Use

Some HGVs can go longer between oil changes, while others may need more frequent servicing. Setting oil drain intervals to match usage helps maintain engine protection without overdoing it on maintenance.
