Where do you check oil on Isuzu npr?

To check the oil on an Isuzu NPR, first ensure the truck is parked on a level surface and the engine is off. Open the hood and locate the dipstick, which is usually marked with a brightly colored handle. Pull the dipstick out, wipe it clean with a cloth, reinsert it fully, and then remove it again to check the oil level against the markings on the dipstick. Add oil if necessary, making sure to use the correct type specified in the owner’s manual.
