Does anybody know for sure?

If it's not in some sort of NVRAM, I'd think that the setpoints would revert to a set of factory defaults instead of nothing. The current values would probably reset to zero if not in NVRAM. Working on another project or I'd look it up (should be in FSM somewhere).

It does, when I had work done on my audio system everything was reset, from the clock to the rev light.

The only thing I had done was the front brakes replaces. Slotted Rotors, Steel Brake Lines and Pads. I dont think they would have to remove or disconnect the batter for that, or to bleed the brakes.

so after that post made me paranoid, I went directly to the car and checked the oil. I last changed it myself a couple thousand miles ago and as I expected it was EXACTLY where it should be. Hasn't lost even a single drop. its NOT normal for any car to burn oil, ever, no exceptions. Thats just what people say that dont want to accept their car has a minor problem. Even on my old 02 WRX people would say "oh thats normal" when it leaks oil. NO ITS ******* NOT!!!!!!!!!!!!! its a design flaw in the subarus case in the head gaskets, easily fixed and now it doesnt leak/burn a drop. If your car burns or leaks oil ITS A PROBLEM. Hell even my first cars built boss 302 "did myself" didnt burn oil and thats a 45 year old engine, so the high performance statement isnt an excuse, its avoidance. stop being lazy. Im an engineer, who goes to school time as well even on weekends and I still have time to lift up the hood and pull a dip stick for 30 seconds, because I care about the condition of my car. Dont rely on on a reminder from the dash computer, thats just proof you dont give 2 ***** about the car. Why not just hire your own personal mechanic to sleep in the garage with the car 24/7, **** it.... just let him drive it too so you dont have to "bother" with it.

Any car ever? How about a RX8?

In all seriousness, a lot of oil consumption is blowby, not the engine burning oil. It's not ideal, but its perfectly normal and a certain amount is to be expected.

lol the RX7 and 8 are a special exception. Thats just again... a design issue. nothing you can do about a stupid idea. Do you without firing up google even know what blowby is? no its NOT ******* NORMAL. its a clear indication of worn or improperly sealed/sized piston rings and if thats "normal" for a VQ engine that simply implies an obvious design flaw. with the correct tollerances, correct viscosity oil, good seals and properly sized rings and pistons a car will NOT have blowby. at least not in any measurable amount, ESPECIALLY QUARTS of oil per X time. we are talking fuckin teaspoons of oil over thousands of miles on a properly designed and maintained engine. Hate to bring up the same example again, but my 45 year old 302 is obviously inferior quality and technology compared to a modern engine, and aside from oil changes ive NEVER had to put oil in it. If your losing QUARTS of oil even over the span of a year, somethings wrong. I never added oil to my 09 once ether in its 40k miles aside from changes....... not sure how much more clear cut the answer can get.

Ok dude, I'm not going to argue with you. Every car maker out there has an acceptable spec for oil consumption. Every. Single. One. That doesn't mean something is wrong. These engines aren't handbuilt. Theres going to be some variance between motors. You've got two that don't burn a drop. Thats great.

You can't compare your old built motor to a production motor. I'm sure you built it with much tighter specs than it originally came with.

Sorry man but you are full of it! You say I dont care about my car.. Just like you said, you have never had a car ever burn oil.. Well, guess what mr Genius, neither have I. I have owned about 20 different kinds of cars and none have either. Why I am supposed to sit there and think this one would too. I baby my car so much people make small jokes about me.. Stop talking out your A$$ about something you have no clue on. Just because you are an engineer does not mean you know everything.. Im an engineer too.. funny, I work for an oil company..

I drive my car hard sometimes,, up and down the canyon here near where I live... I am sure, if you drive it 100+MPH often it will burn something.

I think you need to read this and STFU!

Auto Doctor: Car engines burn oil faster than ever

My old Mustang burned 1 qt every 500 from day one. Ford said that was "Normal". THe point is, I still check my oil every other fill-up.

I think we all learned from this: Don't trust the freakin' computers. They can get accidentally reset. Then something's gonna get braked. I prefer the old fashioned analog sticker-on-the-windshield method. And, as I said above, check it every other fill-up.

So, even though you knew that modern engines can burn oil, you still didn't check your level. :shakes head:

Argue all you want to but checking the oil periodically is an important part of driving a car. Along with checking the brake reservoir level, tire pressure, and sundry other menial chores.

I just now looked that up.. Read before posting..

great you gave examples of engines that burn oil. neat. so does my piece of **** subaru WRX. And know what? I must be one of those smart engineers, because I check and put oil in it. Guess that also means ive owned a car that burns oil. but its a DESIGN flaw in the stock head gaskets, google will tell you all about that im sure. every car ive owned that DIDNT have a known issue, also didnt oink down oil, AT ALL. Neither do my 68 cougar, 70 cougar and 74 hornet and they are over 30 years old lol. The point myself and some others are trying to make is A: you didnt check the oil and relied on a computer to tell you what to do, and B: that my Z and some others DONT. so its not like its a chronic issue with every single one of them and I just recommended you GIVE A **** and maybe use some of your precious time checking into it. You obviously care enough about the car to ask on the forum so dont get pissed when people give you answers you dont wanna hear. especially when you do something dumb.

and I also agree with chuck. production line vehicles are a luck of the draw.

My new Nismo has burned about a quart of oil in 1900 miles. Luckily I check my oil frequently (had an rx8 before this car). I am a little surprised it's burned this much so far. Topping off with castrol gtx. Before the rx8 I had an STI and it burned very little. Meh, o well.
