Frequently Asked Questions

• How often should I change the oil on a Ford F-350?
  Oil change intervals mirror the F-250 since both share the Super Duty platform. Diesel models follow 7,500 to 10,000-mile intervals with full synthetic oil, while gas engines typically use 5,000 to 7,500-mile intervals. DRW models used for heavy commercial work should lean toward the shorter end of these intervals.
• Is there a difference in maintenance between F-350 SRW and DRW?
  The engine and transmission maintenance is identical between SRW and DRW configurations. The key difference is in the rear axle and wheel bearing service. DRW models have additional wheel bearings to inspect and service, and the dual rear wheels require more frequent rotation patterns. DRW models may also wear brake components faster under heavy loads.
• When should the diesel fuel filter be replaced on an F-350?
  The F-350 diesel has a two-stage fuel filtration system. Ford recommends replacing the fuel filters every 15,000 to 30,000 miles depending on fuel quality and generation. The 6.7L Power Stroke (2011+) has a primary and secondary filter, both of which should be replaced simultaneously. Water-in-fuel sensor alerts should never be ignored.
• Does the F-350 require different tires or rotation schedules?
  DRW F-350 models use six tires and follow a different rotation pattern than SRW trucks. Ford recommends rotating tires every 10,000 miles on both SRW and DRW. On DRW models, the inner and outer duals should be swapped side-to-side, and the front tires rotated to the rear outer positions. Tire pressure on DRW models is critical for even wear and safe towing.
