If the sorror for the dipstick justified? Probably not, as we shall prove below. Certainly, to check the oil level in many modern computer systems takes longer than to pull out the dip-stick, clean it, put it in and out again. But, believe me, it's worth it.

Perhaps you like us drove through France in the past, not yet on the Route du Soleil but the Route National. It was a brand gas station with a fraudulent gas station attendant. He opened the hood quite unasked, pulled the dipstick, pulled it off and did not put it back completely.

So he was able to prove that oil was missing and the customer to sell the of course only available two-liter container. The financial loss is added the potential damages caused by too much oil in the engine. One thing is certain in any case, with an electronic oil monitoring all this would not have been possible.

Also considerations must be rejected, any lessons can be learned from the oil droplets on the dipstick. If it were that simple, there would be necessary on big ships any laboratory, which after extensive investigations decides, how much new oil to replace the old in the lubrication circuit (20 tons and more).

The color as an indicator for oil change? Make, for example, after the oil change a little travel with many a diesel engines, then the oil is almost as black as the replaced. No, a dipstick only says something about the amount of oil, provided the vehicle is placed on a horizontal ground and the engine stopped sometime ago.

But as an electronic measurement, so it is all done automatically at certain intervals, has the inestimable advantage, to warn you of too little oil in the engine. Of course must be added, that modern engines consume less oil than older ones.

One of the various possible functional principals is mentioned here. Not only that the temperature of the liquid (oil) is measured and then transmitted to the control device, also the oil-level is measured through the temperature. An electric element heats up the environment around the sensor and the cooling is determined by the resistance. It is a measure of the existing oil amount, and its condition. 01/16
