High oil temp and high oil consumption

cramcram

I've got a 2010 Roadster Sport with two problems.

The first is high oil consumption. It loses about a quart or so every 1500 miles. Fairly consistent since I got the car and it now has 11K miles on it. And yes, it is in the range of VINs listed in the TSB.

The second is more serious. The oil temperature runs hot. And this is in the CA Bay Area where we've had a really cool summer (sorry midwest + easterners). I got a temp of 245 just a couple of days ago with the ambient temperature being only 81. No, I don't drive it on the track, strictly commuting. Oddly enough the water temp seems fine (2 dots below mid scale) on the led display.

The problem is that the car just basically turns into a Prius towing a motor home at about 225-230 degrees. The car scares the crap out of me when I have to make a left turn across freeway traffic from a dead stop (Hwy 17 for you locals). It just barely moves for about the first two seconds then will usually leap forward. I'm going to get T-boned this if this doesn't get fixed.

The dealer doesn't seem to know what to do. They claim to be contacting Nissan about it but I never get a response back from them (the dealer). They weren't even aware of the TSB until I showed them a hardcopy of it. They are doing a 1K measurement of the oil consumption but now that it is getting warmer here I'm getting concerned about getting hit driving the car.

Is there any correlation between the oil consumption problem and high oil temps? Any chance this is a simple as having a bad oil temperature sender? At this rate I'll either cook the engine or my own goose if nothing is done.

Thanks.
