Isuzu Oil Change Guide: Recommendations, Capacity & More

Isuzu-Recommended Engine Oil: Purchasing the Right Oil & Filters for Your Truck

Isuzu engineers recommend following the oil and filter recommendations printed in your vehicle’s owner’s manual. For example, the owner’s manual for Isuzu N-Series diesel trucks recommends using engine oil that supports DPF (low-ash) oil. Engine oils are not a one-type-fits-all product, so consult with one of our professional service center members if your owner’s manual is unavailable.

Pro Tip #1: The viscosity, or thickness, of an engine oil is listed as a part of the oil’s name, indicating both hot and cold viscosities. The number preceding the “W” indicates its cold temperature viscosity, and the number immediately after the “W” indicates its hot, or normal operating, temperature viscosity. For example, 10W-30 has a cold viscosity of 10 and a normal operating viscosity of 30. The higher the number, the thicker the oil.

Pro Tip #2: Choosing a higher-viscosity genuine Isuzu oil for your truck won’t necessarily improve engine protection, and in some cases, the wrong oil weight can actually lead to increased fuel consumption or extra wear and tear.

Choosing the right oil filter is also important. Oil filters can also vary in size and style, so finding the proper Isuzu oil filter is key. An oil filter sieves dirty oil through small holes and retains dirt or grit, then the clean oil is returned to the engine. Genuine Isuzu oil filters can be ordered and installed at our Nimnicht Isuzu service center at the same time as your oil change.

Signs You Need an Isuzu Oil Change: When Should You Schedule Service?

The best time to schedule an Isuzu oil change is at regular intervals, typically every 7,500 to 10,000 miles, though some models only require oil service closer to 25,000 miles. The real oil change interval depends on your specific truck and use conditions. Yes, this advice might sound trite, but it’s also true. Routine upkeep is critical to maintaining a healthy vehicle.

However, there are also a few signals your truck might give you that indicate you need an oil change. Aside from an illuminated check engine light, here are some telltale signs you need to service your Isuzu truck:

• Your dipstick reveals low, gritty, or dark-colored oil
• You see exhaust smoke coming from your tailpipe
• Your engine is making unusually loud knocking or ticking sounds
• Your fuel efficiency has noticeably decreased
• You smell burning or oily aromas inside your cabin
• Your vehicle stalls or shakes while idling

Remember that your transmission also needs to be monitored, so keep an eye on your Isuzu transmission oil for optimum performance and change it every 30,000 to 50,000 miles or so. Transmission oil lubricates the metal parts and bearings inside your truck’s transmission. It also helps the torque converter and valve body to operate smoothly.
