2018 Ford F-350-Super-Duty Oil Change in Lakewood, CO

For most 2018 Ford F-350 Super Duty trucks, change oil about every 7,500 miles under normal use, and closer to 5,000 miles in severe Colorado conditions.

Denver-area towing, cold starts, dust, and stop‑and‑go traffic shorten oil life. Gas 6.2L owners typically follow 7,500 miles/6 months, while many 6.7L diesel owners target 7,500 miles with shorter intervals when idling or towing frequently. Our Lakewood climate and elevation justify the conservative end of the range.

• Normal driving: ~7,500 miles
• Severe duty (towing, dust, short trips): ~5,000 miles
• Book a schedule service slot to keep records current

The 2018 F-350 6.2L gas typically uses full-synthetic 5W-20 meeting Ford spec, while the 6.7L Power Stroke diesel uses heavy‑duty oil (often 10W-30 or 5W-40) meeting Ford diesel spec.

Viscosity depends on engine and temperature range. In the Denver metro, cold-start pumpability favors the listed grades, with 5W-40 commonly chosen for severe diesel duty or winter towing. We install oil that matches your engine build and local use, and include a Ford-spec filter.

• 6.2L gas: full-synthetic 5W-20 (Ford-approved)
• 6.7L diesel: 10W-30 or 5W-40 (Ford diesel-approved)
• Includes OEM-spec oil filter replacement

The 2018 F-350 6.2L gas engine holds about 7.0 quarts, while the 6.7L Power Stroke diesel holds about 13.0 quarts with filter.

Capacity varies by engine, so we confirm your VIN before filling. Using the correct volume is critical for pressure at altitude and during heavy towing on I‑70 grades. Our service includes precise fill and a hot recheck after the test drive.

• 6.2L V8: ~7.0 quarts
• 6.7L V8 diesel: ~13.0 quarts
• Proper level verified after engine warm-up

Yes for many owners—dealer oil changes include OEM-spec oil/filter, multi-point inspection, fluid top-offs, and service records that support warranty coverage.

Quick-lube shops can be convenient, but heavy-duty trucks need the correct Ford-approved oil and filter, especially for the 6.7L diesel. At Larry H. Miller Ford Lakewood, we document service and check common F-350 wear points that local work trucks face.

• OEM-spec oil and filter matched to 6.2L or 6.7L
• Documented multi-point inspection and fluid top-offs
• Service history helps with warranty validation

Skipping required oil changes can jeopardize warranty claims if maintenance intervals aren’t met and records aren’t available.

Ford requires maintenance per the owner’s manual; if an engine issue arises, proof of proper oil and intervals is often reviewed. Warranty work generally must be performed by a certified facility, and documented services at our Lakewood dealership help demonstrate compliance.

• Follow Ford’s mileage/time schedule
• Keep receipts showing oil spec and filter type
• Certified facility documentation supports claims

Full synthetic offers the best protection and stability, especially in Denver’s temperature swings and towing; many 2018 F-350 engines specify full synthetic.

Conventional oil is budget-friendly but less stable under heat and load. Synthetic blend improves oxidation resistance, while full synthetic resists shear, flows better at cold start, and handles heavy loads—key for F-350 gas and diesel engines working at altitude.

• Full synthetic improves cold-start protection
• Better high-temp stability for towing
• Meets Ford approvals listed for your engine

The 2018 Ford F-350 Super Duty uses different oil specs by engine. The 6.2L gas V8 typically calls for full-synthetic 5W-20 meeting the Ford approval for that engine, with an approximate capacity of 7.0 quarts including filter. The 6.7L Power Stroke diesel uses heavy-duty engine oil—often 10W-30 for most temperatures or 5W-40 for severe service—meeting Ford’s diesel oil specification, and holds about 13.0 quarts with filter. Standard intervals trend near 7,500 miles under normal conditions; for severe duty in Colorado (towing, dust, short trips, cold starts), shorten to roughly 5,000 miles.
