Truck Oil & Fluid Services in Cumming, Iowa

Mechanic changing engine oil of the truck at Absolute Repair

One of the best ways to help ensure and protect the longevity of your truck is regular oil changes and fluid checks. With so many moving components, proper lubrication is crucial for your diesel truck to maintain the parts and prevent premature ware and deuteriation.  

How long you can go between oil changes is dependent on a variety of factors. Most vehicle manufacturers recommend that you change the engine's oil and oil filter every 5,000-10,000 miles, but this can vary depending on how you use your truck and the type of oil you use. For example, road conditions such as hills and mountains, stop-and-go traffic, or consistently carrying a heavy load can all cause your engine to work harder and require more frequent oil changes.

In addition to changing your oil according to the manufacturer's recommendations, you should check other vital fluid levels at the same time. For example, along with an oil change, transmission fluid, brake fluid, coolant levels, windshield washer fluid, and even tire pressure should all be checked. 

What can cause oil leaks in diesel engines?

Most oil leaks are a result of the deterioration of a part of your engine. The most common cause of oil leaks is the oil gasket. Sludge starts to build up if the engine gets damaged or as it starts to degrade over time. This sludge causes the oil gasket to break down and then oil starts to leak.

Leaks can also initiate from the oil pan. Since the oil pan is on the underside of your truck it is vulnerable to getting hit by rocks, branches and other debris on the road. All of these can leave small dents in the pan which can easily turn into holes where the engine oil can leak from.

If the oil filler cap is not secured properly or missing entirely, parts of your engine can become covered in oil resulting in oil leaks. The oil filter itself can also be the cause of oil leaks due to the filer wearing out, becoming misaligned or coming loose.

Our certified technicians at Absolute Repair can help to diagnose exactly where the oil leak is coming from and devise an affordable and effective solution to have your diesel engine in smooth operating condition once more.‍

What Our Customers are saying About Us


While on vacation recently we unfortunately encountered a broken axle on our travel trailer. Being from out of town and the fact that it was a Sunday evening we had no idea who to call for repair. The tow truck driver recommended Absolute Repair and we were towed to that facility. The tow truck driver notified the owner of Absolute Repair that we were in their parking lot. On Monday morning we were greeted by Andrew who evaluated the situation. Peter (the owner) and Andrew were very easy to work with and kept us informed of their efforts to secure a new axle. Once they had the axle they worked quickly and diligently to put the new axle on the trailer and we were back on the road late Monday afternoon. Peter himself worked with another tech to complete the repair. Peter and Andrew are both very knowledgeable, explaining in detail the repair, as well as being concerned for our comfort and offering us the use of their lounge. The repair price was very reasonable. Andrew even placed a follow up call to us the next day to make sure everything was fine with the trailer. We cannot speak highly enough of this company and would recommend them to anyone without hesitation. Our sincere thanks to Peter and Andrew for assisting us and getting us back on the road so quickly.
