 This is the first American engine that does not have a dipstick. Some of these pickup truck drivers really put their vehicles to work. You know, think about the way they use trucks in Texas, hauling cattle and hay and lots of heavy loads. Truett says some work truck drivers check their oil level daily. Now, most of us don't check our oil that much, and having a sensor means less need to look under the hood. This is another way to maybe for you to get the car back to the dealer or maybe to Jiffy Lube or someplace like that.
