Conventional, synthetic, and diesel oil changes for light- and medium-duty trucks, vans, and fleets — done right by ASE-certified technicians in Greeley.
Where can I get a truck oil change in Greeley?
Truck City Service performs conventional, semi-synthetic, full-synthetic, and diesel oil changes for light- and medium-duty trucks, vans, and fleets in Greeley, CO. Our ASE-certified technicians drain the old oil, refill with the correct grade, and check your filters — keeping your engine protected and your trucks on the road.
Cheap Insurance For Your Most Expensive Part
An oil change is the cheapest maintenance you’ll ever buy — and the most expensive one to skip. Clean oil is the difference between an engine that runs hard for years and one that grenades a bearing when you can least afford the downtime.
“We see it most on work trucks and diesels that ‘sound fine’ — oil black as tar and a filter packed solid. A ten-minute drain and fill was all that stood between them and a rebuild.”
— Truck City Service team, Greeley CO
That’s why we don’t just dump and go. Every oil change uses the correct oil grade for your engine and includes a filter check, so small problems get caught while they’re still small.
Oil Types We Offer
The right oil depends on your engine, your mileage, and how hard your trucks work. We’ll help you choose.
Conventional
The original, most cost-effective oil. Great for lighter-duty use — just needs changing more often.
Semi-Synthetic
A blend of synthetic and conventional. Midrange cost with longer life than conventional alone.
Full Synthetic
Lab-engineered for the best protection and the longest intervals. Easier on filters and worth the cost.
Diesel Oil
Diesel engines need their own oil. We match the right diesel oil to your engine, including Isuzu.
Oil Change Interval Guide
A simple starting point. Hard use, towing, and severe duty all shorten these — we’ll tailor a schedule to your trucks.
| Vehicle / Oil | Typical Interval | Notes |
|---|---|---|
| Light-duty, conventional | 3,000 – 5,000 mi | Most frequent; budget option |
| Light- / medium-duty, full synthetic | 7,500 – 10,000 mi | Longer life, easier on filters |
| Diesel (incl. Isuzu) | Up to ~10,000 mi | Use diesel-specific oil |
| Hard-use / fleet | Shorter, by hours & load | We’ll set a schedule |
General guidance only — always follow your owner’s manual for your specific engine. Ask our service advisors to build a plan around your vehicles.
