How Often Should I Change My Heavy-Duty Vehicle's Oil?

The frequency of heavy-duty oil and fluid change will vary depending on the type of vehicle, its usage, and the manufacturer's recommendations. Similar to the frequency of oil and fluid service, the recommended interval for oil changes will vary based on the vehicle and its usage. We generally recommend oil changes every 5,000-7,500 miles for heavy-duty vehicles.

Should I Use Fully Synthetic Oil Or Semi?

The choice between fully synthetic oil and semi-synthetic oil depends on your vehicle's needs and usage. Fully synthetic oil offers superior protection, better performance in extreme temperatures, and longer intervals between oil changes. It's ideal for high-performance or heavy-duty engines. Semi-synthetic oil provides good protection and is more cost-effective, making it suitable for regular driving conditions.

Customer Testimonials

"I have used Southeast fleet service for 20 years and They have always performed exceptional work."
- Michael

"My semi truck broke down yesterday in the afternoon in Salisbury, NC and i was lucky enough to find these guys to help me fix it. I had issues with electrical cable, and other harness issues. They took me in immediately, fixed it and i was on the road in less than an hour! They were professional and knew what they were doing. Next time I'm around Salisbury area and have issues with my truck i definitely know where to go! Thank you guys...and thank you Spencer!"


"Being the Director of Maintenance with Hilco Transport I can tell you that these guys do a very professional job from start to finish. We had a wrecked cargo tank that needed a good bit of work. Brian Brewer in the shop walked us through the repairs needed going over the tank, providing an estimate for the repairs and kept us informed througout the repair process. Once the tank was complete our in-house tank techs reviwed and were happily impressed. That being said, we have taken them additional work including a cargo tank refurb job. Check these guys out! You will not be let down!"


"Had a problem with the pump on one of trucks being locked up do to driver leaving product in it. Called Brain and he got me in that day and out the next!!! Thanks for getting me in and out as to not miss out on any loads."


"Called them up for airbag replacement on trailer & they took me right in not to say that they offered to help me get there if my air pressure didn’t build up. Great group of guy’s & professional on every level."
