Me, speed gets to be more of a feel and sound thing. I don't believe I watch the speedo that close. Wonder how many people are watching their fuel level gauge these days.

I keep an eye on gauges in everything I drive, it's just a habit. I had an oil pump fail a few months ago and shut it off immediately when the pressure dropped to 0 at a red light. OTOH, my wife probably wouldn't notice without a light. If her 240D ever loses oil pressure, I will be buying an engine.

My dad used to fly, so we all got the habit of doing a gauge glance at least every 15-30 seconds to make sure we still have OP and weren't overheating. Flying through the air in a Cessna, you really want to know these things... so the habit just sort of got passed on to our cars. Plus, all our equipment is old. Just makes sense.

My mom, on the other hand, could be driving a car that did a "Red Alert" siren from the Enterprise when there was a problem, and still keep right on going until it locked up.

LOL.

Maybe I'm checking them and don't even realize it.
Thats one thing I don't like about the 98 Beetle I'm driving, theres no temp gauge. When you start the car there is a blue light indicating the engine is cold, that goes out and then there is nothing to tell you what the temp is.

Yes, I know. But I still think that the Stainless steel set up that I did is far superior to mercedesbenz hoses. I drive way too far to have MB proprietary hoses to leave me stranded.

I have about 200K on my current stock hoses, I'll just replace them again when it's time. They're just another maintenance item.

There's no question that an oil-pressure-loss can be catastrophic and all you have to do is not notice that the gauge has gone to zero.

I looked into the idiot light thing, maybe with a buzzer or flasher attached to get your attention. All you have to do (on cars with mechanical gauges) is to tee into the pressure line and add an oil pressure switch connected to a warning lamp. Maybe a flashing LED would work.

For cars that have electrical oil pressure gauges, there would be a little bit more of a challenge. You would have to design and build a circuit with a transistor or an op-amp to sense the low voltage and trigger a lamp.

Shame that Mercedes didn't add to the meter needle a contact that would light a warning lamp at zero. It might be possible to retrofit such a thing, I suppose.

My 535i had a low level sensor. Has anyone modified their cars to give you warning? Doesn't seem like it would be hard to do. I'd like something like a red LED and audible. Not to make up for stuff thats Mickey Moused, but our cars are getting older and sometimes other people are driving the cars who don't really look at the pressure gauge. You could tell them if you see the red LED come on, shut the car down ASAP. The oil pan being steel, it should be easy to adapt a oil level sensor. It seems to me that someone must have done this in here.....
Found it.....you mean something like this?
Low oil pressure indicator

Definately. The MB ones will definately be better than any farmer-boy rigged ones, but I think my stainless ones were cheaper and better than the MB ones in my opinion.

I'd say a buzzer is superior to an idiot light because our field of hearing is broader than our field of vision, not to mention that buzzers are far more irritating than idiot lights.

Hobbs makes many different pressure switches. http://cgi.ebay.com/NEW-HOBBS-PRESSURE-SWITCH-10-PSI-NORMALLY-CLOSED_W0QQitemZ180223962312QQihZ008QQcategoryZ67006QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
I think the thing to do is find a chime you like instead of a buzzer. Although most any car I buy its like one of the first things I pull as I hate noises. It would be nice to not have the circuit triggering the chime when the motor isn't spinning.

Kerry is on the money here.... I was a pilot and used to have a good crosscheck.. but if you research the situation you will find that the IMPORTANT warnings in an aircraft are now AUDIBLE.... if you had a perfect 30 second crosscheck all the time you could still be 28 seconds late finding out that your oil pressure had gone to ZERO....

Dont know about warning systems on cars but on marine engines that I am familiar with, the buzzer goes off every time you shut the engine down (low O/P), then you reset it. A red strobe light might be better

Oh good, another buzzer that I would have to disconnect. No thanks, I like the gauge. If I'm not paying attention to the gauges, I deserve to buy a new engine. I really hate buzzers and idiot lights.
