I remember when we checked engine oil and transmission fluid by pulling the dipstick out, wiping it clean, putting it back in, and pulling it back out. That simple process enabled us to check the fluid level. We could tell many things by that dipstick, but today it isn’t that simple. Many new models don’t even come equipped with an engine oil or transmission dipstick!
Modern automobiles have become marvels of precision and durability over the years. Many transmissions have 5, 6, 7 or even 8 speeds and do not have a dipstick to allow checking or adding to the fluid level or inspecting the fluid condition, unless you have specialty tools to do so. Some engines are following suit by removing the dipstick as well. These cars rely on the engine computer to check oil level and condition. Not sure about you, but that scares me.
Vehicles with dipstick-less engines and transmissions came about to keep people from adding incorrect fluid. A person or non-qualified shop would add or change the fluid using the incorrect type. The engine and/or transmission would fail prematurely because the less-expensive fluid did not lubricate properly, and failure was eminent. The consumer might put the fault on a poorly designed or defective car. This is happening more and more.
Some of these engines and transmissions are filled with what the manufacturer says is “long life” fluid, claiming it does not require changing for many miles. I recommend you find a trust worthy service center and use the manufacturer recommendations along with your service advisor recommendations to make the final decision on when to service your car.
With rules regulating the automotive manufacturers that mandate fuel mileage be increased every year, vehicles require very specific synthetic fluids. The cost of today’s fluids can be staggering, ranging from $6.00 to $26.00 per quart. Adding the wrong fluid will damage the internally lubricated parts over time.
Please do your homework when having any service performed; it can be devastating if the wrong fluid or incorrect fill procedure is performed.
