Username Protected wrote: Seems like an easy add for a company like JPI, EI, Insight Yeah, changing the software so that “oil quantity” appears on the screen would be easy. Everything else associated with getting it approved wouldn’t be worth the time it would take. First a sensor would need to get approved. Then you need to figure out where to mount it on all the applications they want to offer it on. Since no OEM has done it you can’t just pop the OEM sensor out and install the EI/JPI, etc. They’d have to do all the engineering themselves and get approval to cut holes in oil sumps. Good luck.

Porsche has a true dry sump with a separate oil tank and no oil residing in the engine. There is a scavenge pump to pump the oil out of the bottom of the engine into the oil tank.

Greg How would you attach that to the oil pan? My canted engines have two drain plugs so it would be pretty easy to replace the higher one with a sensor but for engines with only one drain in the sump it might not be feasible. You'd also want to make absolutely certain the sensor couldn't fail in a way that let the oil out or you'd be creating an opportunity to lose the oil.

Greg Not just the Japanese. Ford had them in the ‘80s, too. I imagine pretty much all auto makers did.

You're right, thinking oil cooled, vs dry sump.

The engine manufacturers would have to do some groundbreaking engineering and add a threaded fitting to the oil pan at the minimum oil level point for a sensor. Since it’s a almost zero pressure area, chances of a large leak occurring would be nearly nil. Continental engines already have a enough other spots likely to lose oil, which is the reason the sensor might come in handy. Or you could just build a dipstick that is a level sensor. The lead attached to it would of course be a pain.

Greg You could have the contacts built into the screw in portion. So automatic connection/disconnection.

Not much chance for a big oil leak there.
