No oil consumption
My 2005 RX-8 (bought in June) has 2300+ miles on it. I checked the engine oil a few times already and it hasn't moved a bit. The oil meter also says the same thing. Is this normal or has the last TSB really got it right? The dealer said they applied all the latest TSB before they let the car out of the lot.

I have right around 6000 miles on my car, two oil changes, and my car has used up 2-1/4 quarts of oil so far, so it seems to be around what others have reported of 1 quart per 3000 miles.

Most the time, I'm at around 4500 RPM on the freeway and move up to 5-6K RPM when I need to zip in+out. I rev it up to around 7-8K a couple of times per week. I use up 1 tank of 92 octane gas per 5 day week. Weekends I use another vehicle.
Is this still normal?
I also notice that as the weather gets cooler (we're getting 55-58 deg mornings these days) , the mileage is also beter for gas consumption.

There's an oil TSB? o_0
Anyway, my dipstick's oil moved from a notch above medium to below low in like 900 miles. I started the car up today and saw the oil sign. My heart skipped a beat, so I ran over to my stash of 5W-20 oil and fed it a quart and a half . I should probably cut down on the redlining....I hit the rev limiter a dozen times a day maybe?

The oil pressure gauge is a dummy gauge, it will never read anywhere else except a little off center, you should always rely on visually checking it yourself.

I was wonder'n about this too, at 16000kms (10000 miles), three oil changes, hitting the redline daily, I'm using far less than before. Less than half a qrt. over the last 1000! I still check after every 2nd fill, or 800kms.
And yeah, forget about the gauge. But I remember Car & Driver's long term RX8 having the oil light coming on "constantly" to remind them to top up.

What do you mean, "got it right"? It's SUPPOSED to use oil by design. Perhaps you had unrealistic expectations due to the overblown oil consumption threads here. Or maybe it was just overfilled when you took possession. Either way, stop obsessing and enjoy the car. Check the dipstick every other fill up, and when it gets low, add oil. And stop using the oil pressure gauge as an oil level gauge.

Mine actually consumes virtually no oil as well.
That is one of the reasons I use premix these days.
I change my oil every 3k miles and if it uses 1/8 of a quart in that time it is a lot.

If he has a manual then he's averaging 90 somethin' or he is driving in fifth.
Personally, I think that he has a reason to be worried. Driving at those RPMs he should be going through about a 1/2 quart per 500 miles. I would have the dealer check the metering pump and make sure that all is going alright.

65 MPH in 4th is 4500 RPM or so. IIRC, that is about 80 in 6th. (I'm sure I'm off, but it is in the ballpark.)

Either that or I don't understand why you'd use lower gears when cruising on the freeway, unless you forget to shift. Not that this has ever happened to ME, of course. I've never had it in fifth for about ten minutes before I realized what I was doing. Never.
