When trading, I came across numerous engine failures of vehicles not fitted with mechanical dipsticks, notably Mercedes Benz, but others too, so was disappointed to say the least, when Jaguar adopted the ludicrous electronic system, replacing a simple, idiot proof device with a time consuming procedure which few would bother with.
I have taken to doing a cold check weekly (against Jaguar advice) simply because I have no wish to start and warm up an engine containing insufficient oil. The result is that depending upon ambient temperature, the linear electronic gauge shows full or a few mm away from full, and always: "oil level ok". I also, when I remember, ten minutes after a run, check it in the approved fashion, warm.
For dieselers, however, the dangers are magnified, as their engines are prone to filling up with fuel which can, and frequently does, cause sudden catastrophe as described elsewhere:
If ever there was a case of "If it isn't broken, don't fix it." this is it. While I'm moaning, why do we who drive on the correct side of the road have to put up with a bonnet release on the wrong side of the car, where only the passenger can reach it?
Doesn't a low level warning come up, as well as being able to check electronically? I have to admit I never check mine on the XK. The XE has a dipstick (other than the one behind the wheel) but synthetic oils don't get as dirty as of old and it's quite difficult to get a proper level on it, so I don't bother with that one between services either.
