How Often Should You Change Oil In Diesel Truck?

Oil changes for diesel pickups are usually recommended every 5,000-7,000 miles or every six months on cars that pull moderately. You might be able to go much longer if you don’t tow or don’t tow very often.

How long should you change oil on a diesel engine?

Oil changes are normally recommended every 100 hours and at least once a year, according to engine manufacturers. Even though your engine handbook specifies a longer time between oil changes, changing the oil more frequently will help the engine last longer.

For gasoline engines, a hundred engine hours between oil changes is acceptable, but diesel engines are significantly more demanding on their lubrication. A diesel engine’s oil should be changed every 50 hours or so. For sailors who only use their motors for an hour or two per voyage, the shorter period is extremely essential. When dirty oil sits idle, it causes damage to the engine’s internal surfaces. If your boat will be idle for an extended period of time, such as the winter, it is critical to drain the tainted oil and replace it with fresh oil.

Unfortunately, regular oil changes are more often the exception than the rule, owing to the difficulty and messiness of changing the oil in a boat engine. While draining the oil from a car engine takes about a minute, the oil drain plug on a boat is sometimes out of reach or non-existent. Even if the plug is accessible, there is frequently insufficient space beneath the engine for a container to catch the oil that is draining.

Finding a procedure that works for your engine installation is the key to hassle-free oil changes. Here are some options to consider.

Through the Drain Plug

A foil roasting pan from the grocery might fit beneath your engine and serve as a catch-all for used oil. To make sure the pan can hold all of the oil, fill it halfway with water. When using foil pans, keep the bottom solid by placing a piece of thin plywood under the pan. To collect the inevitable splash or spill, place an oil-absorbent cloth beneath the pan.

If you tie the mouth of a plastic waste bag to a tin can with both ends removed, you can drain the oil into it. In a small place, a pineapple can be useful. Because hot oil has a tendency to seep through some plastics, use two heavy-duty bags, one on top of the other.

You can “decant” the oil into any container lower than the engine sump by replacing the drain plug with a hose fitting and a length of hose. There are kits available that include hose and fittings, or you may make your own using a threaded hose barb and oil-resistant tubing. Make that the barb and the plug have the same threads. Attach a second barb to the hose’s free end and cover it with a cap (or a plug). Except when emptying the oil, rig a hanger to keep the end of the hose high above the oil level.

Use a similar hose connection between the drain plug and a brass piston pump to pump the oil out of the engine if space below the engine is insufficient for a container. Oil removal is as simple as a few strokes of the handle when the pump is permanently mounted to an engine compartment bulkhead. If you don’t mind the cost, using an electric pump designed for hot oil reduces oil draining to a matter of flipping a switch.

Through the Dipstick Tube

Many marine engines lack a drain plug or are too difficult to access even for a hose connection. The oil in these engines must be sucked out through the dipstick tube by a pump.

The dipstick tube on some engines is threaded. With a few tugs on the handle, the included oil-change pump screws straight to the dipstick tube and the oil is extracted. This works well in areas with easy access. Otherwise, you may install the pump to a handy bulkhead and use a hose with threaded fittings to link it to the dipstick — effectively a very short garden hose. Next to the pump, mount a short length of PVC pipe with a male hose adapter to give a location to “park” the hose when not in use.

To retrieve the oil from a dipstick tube that isn’t threaded, use a pick-up tube placed through the dipstick tube. The majority of oil-change pump pick-up tubes are plastic tubing with an unreasonably tiny internal diameter. By replacing the standard pick-up tube with thin wall brass tubing, which can be found at most hardware or hobby stores, this typical technique of oil removal can be transformed from torturous to fantastic. Purchase the largest tube that will slip into your dipstick tube, usually not less than 5/16 inch in diameter. My Yanmar diesel accepts an 11/32 tube with ease. Make sure the tubing is long enough to reach the engine oil pan’s bottom. A length of rubber hose connects it to your pump. Mounting the pump to a bulkhead simplifies the operation once again. Install a length of PVC tubing, capped at the bottom, for parking the pick-up tube if you do this.

How long can diesels go without oil change?

Oil should be changed every 3,000 miles or three months in gas-powered automobiles and trucks, according to popular wisdom. However, this isn’t always the case with diesel-powered automobiles.

When should you change the oil in your diesel engine? A diesel-powered automobile or truck may be able to go longer between oil changes than a gas-powered vehicle, depending on the following factors:

  • What you do with your car is up to you (such as often hauling heavy loads or towing a trailer)

Assume you take short journeys around town and rarely exceed 60 miles per hour. If this is the case, you may need to change the oil in your diesel-powered vehicle more frequently than a diesel-powered vehicle that drives at highway speeds on a regular basis.

Why? Because the oil in a diesel engine acquires muck and impurities more quickly at lower speeds and temperatures than when the vehicle is driven at greater speeds and in hotter weather.

If you’re not sure, consult your owner’s manual for the manufacturer’s recommended oil change intervals for your diesel engine.

Here’s an example of what Ford advises for the oil change interval for a 2018 Ford F-150 with a diesel engine.

Also, Ford warns against driving for more than 10,000 miles or a year without changing the engine oil. (Yes, caps included.)

Do diesel engines need oil changes?

Diesel engines, like gasoline engines, require routine maintenance, which includes changing the lubricating oil that keeps your vehicle’s components functioning properly. Check your oil dipstick once a week at the absolute least, and change the oil filter whenever you change the oil.

What is a lot of hours on a diesel engine?

Diesel engines can survive between 6,000 and 8,000 hours with good maintenance before requiring substantial repairs. As a result, some diesel engines on boats can endure a long period. Diesel engines are popular among boaters since they are long-lasting.

How often should you service a diesel engine?

Car manufacturers propose service intervals based on mileage or time, such as every 15,000 miles or every 24 months. Only if you haven’t achieved the mileage limit does the time limit apply.

Most cars will need servicing after this amount of time and mileage, however it varies slightly from car to car. Some high-performance automobiles may require more frequent servicing, but high-mileage (typically diesel-powered) cars may have a ‘variable’ service plan, which implies they will not require as much maintenance.

How much does it cost to change the oil in a diesel truck?

A diesel oil change is a necessary aspect of your diesel vehicle’s routine maintenance. Diesel engines, like gasoline-powered cars and trucks, require proper lubrication to stay in good working order. Under ideal conditions, a synthetic diesel oil change can last for years without needing to be drained. Two synthetic diesel possibilities to consider are Amsoil and Mobil 1, but you should never skip changing your diesel oil just because you believe you can. If you have any questions about how long your synthetic oil will last, you should speak with your mechanic. Every diesel owner should be aware of the fundamentals of a diesel oil change. When it comes to getting your oil changed, consider things like cost, drain intervals, and brand selections. Knowing how to do it yourself is also beneficial.

Depending on where you go, an oil change for a gas-powered automobile or truck will cost between $20 and $30. Individual mechanics often do a better job for a little more money than chain lube stations, which may offer sales or specials. The cost of a diesel oil change, on the other hand, ranges from $50 to $70. It will be more expensive if you utilize synthetics. This is due to the fact that diesel fuel, which includes oil, is often more expensive than gasoline. It all depends on where you get your oil changed.

Oil changes for gas-powered automobiles and trucks are recommended every 3000 miles or three months, according to popular knowledge. Of course, this does not imply that your automobile will explode if you wait till 3500 miles. It’s simply a guideline from the manufacturer and the oil company. This number increases to 7500 miles for diesel trucks.

Are diesel engines expensive to maintain?

Because replacement parts, labor, and routine maintenance are more expensive in diesel engines, they cost more to maintain than gasoline engines. The initial purchase price and maintenance costs, on the other hand, may be overcome by their fuel economy and lengthy lifespan. We hope you’ve learnt something new about diesel engines and are better prepared to decide whether or not to buy one as your next vehicle.

Why are diesel oil changes so expensive?

A diesel oil change will cost you different amounts depending on where you go. Diesel oil changes are generally more expensive than conventional oil changes since diesel fuel and oil are more expensive than petroleum.

Do diesels require more maintenance?

Depending on the type, a diesel automobile or truck can have lower maintenance costs than a gasoline-powered vehicle. A diesel engine doesn’t need spark plugs or distributors, which are more important parts of a standard internal combustion engine’s maintenance plan. Diesel fuel is also light enough to act as a lubricant as it passes through the engine, which aids in its optimal operation.

Depending on whether you’re hauling a moderate or heavy load or idling a lot, oil changes may become more regular. However, it is still less frequent than an oil change in a gas-powered automobile or truck, which may be required every 3,500 to 5,000 miles.

In addition, a fuel-efficient diesel engine wears down less quickly than a gas engine, so it spends less time in the shop. It is designed to sustain higher compression than its gasoline-powered cousin, making it more efficient over time. All of these factors combine to make a diesel car less expensive to maintain in the long run.

Do diesel trucks require more maintenance?

Diesel trucks are more expensive to repair than gasoline trucks. Some may argue that diesel engines are less expensive to maintain since they don’t use a spark plug, however this is only one reason. Diesel engines have parts that gasoline engines don’t, and thus need to be serviced more frequently. Furthermore, their overall parts costs are higher. Furthermore, due to a scarcity of qualified technicians, you may need to go a bit further to find a qualified mechanic to conduct repairs.
