Commercial Truck Service FAQs


  • Can You Patch a Tire on a Semi Truck?

Yes, a semi truck’s tire can be patched. If the area that needs repair is on the tread area of a tire, the repair can be done, but if it's on the side of the tire, it's a different story. It is also important to make sure that the patches and repairs don’t overlap!

  • How Do I Know if My Engine Needs an Overhaul?

Your engine will let you know when it needs an overhaul! Just look out for these signs: low power, hard to start, bad fuel economy, white or blue smoke, high crankcase pressure, low oil pressures and high oil consumption. If your truck starts to have any of these problems, be sure to bring it in for diagnosis to ensure your engine lasts longer and runs smoothly. Even if you're semi isn't exhibiting these issues, you should always follow your engine manufacturer's recommended engine maintenance intervals. While you're in, let us check out your quality def sensors to make sure they are working properly! Be sure to keep an eye on your truck's transmission too!

  • How Often Should My Truck’s Oil Be Changed?

Follow the engine manufactures guidelines for when oil changes should be performed. Most engine manufactures now base oil change intervals off of fuel economy, so the better your fuel economy the higher mileage the interval will be. No matter what, make sure your commercial truck's oil filter is up to part as well! While oil changes are extremely important, you should also be sure to consistently check on your transmission fluid and break fluid!

  • How Often Should I Replace My Semi Truck’s Battery?

This will depend on a number of factors. Some of these factors include: the type of battery you are using (Flooded, AGM, ETC), your trucks application and how it's being used, how long it sits between uses, and more. If you allow the battery to decay too far down before charging you often are unable to recover the battery voltage.
