Exactly.....As I said in yet another thread on this, Very few manufacturers will give you the time of day if you're not burning more than a quart/1000 miles. Chevy (for the Corvette) even has a published bulletin that says 1 qt per 500 miles is acceptable if used in an aggressive manner (aggressive being defined as operation above 3000RPM's...LOL). A quart between changes, or even 2 in a 3700 mile change interval would not be considered excessive enough to warrant correction with most all companies...
When you get into the serious usage area (exceeding a Qt/thousand) they will do a monitored test by documenting miles and sealing your oil fill to determine true usage.

Very few cars on this forum are even fully broken in yet, so this discussion is all a bit of an overreaction..

Maybe Lou could let us in on Nissan's guidelines on oil usage if they have any..

Not only that, they even tell you to put an extra quart in before a track day, as you will burn it.

That being said, the engine on my 03 350Z was replaced under warranty for oil consumption at around 25000 miles. It had 35% leakdown in one cylinder, 55 in another and the rest were all around 10.

Very true. My Subaru did not burn oil, it drank it and the compression was always spot on.

FuszNissan · 08-12-2009, 09:27 AM

I burned 1/2 qt in an half an hour in idle. That is an "Oil Comnsuption Issue" If you burn 1-2 quarts in 3000 miles, don't worry about it. I think the lesson to be had in this thread is CHECK YOUR OIL levles often. This was a quality issue on a part, and I am guessing seals, but we will never know. Burning 1 quart don't worry! Just make sure you are aware of what is going on in your car!

You mean the sky isn't falling? I can take my tin foil hat off? Whew!

kannibul · 08-12-2009, 09:34 AM

Sorry, this is the first I've heard of a car that burns this much oil is considered "normal".

My truck with 140,000 miles on it, doesn't burn this much oil.

My honda civic with 70,000 miles on it, doesn't burn oil (and it revs all the way up to 6500 RPM before redline)

If it turns out it does burn this much oil, then why bother with changing it - just swap filters and top it off all the time =/

m4a1mustang · 08-12-2009, 09:47 AM

Well it really isn't very difficult to keep under control. Just check your oil regularly and top off as needed. Eventually you'll know what is normal for your specific car and it will become second nature.

I burned maybe 3/8ths of a quart in almost 1500 miles. At this rate I might burn a full quart in 4500 miles... not that big of a deal. I just need to make sure I keep a supply of Redline on hand.

I do think it's important that this issue is raised, though. There are going to be a lot of new owners coming from cars that don't really burn any oil... they aren't going to know that they need to be checking levels regularly and could use a little nudge in the right direction.

Another thing to keep in mind on this, a lot of people seem to be checking in and saying "I just checked my oil for the first time at 2K (or whatever low number) miles and it's low". That doesn't necessarily mean anything about oil consumption if this is the first time you've looked at your dipstick on the factory fill. For all you know, it was filled slightly low at the factory. To measure consumption, you need to have a baseline from you checking the dipstick yourself at an earlier mileage, and you need to check the dipstick under roughly identical conditions both times in terms of how hot or cold the engine is when you shut it off, and how long you wait to check. Personally I like to get the engine fully warmed up (180+ oil temps, preferably 200), then shut it down and wait about 10 full minutes to check the level.

I have a baseline. I burned oil after my oil change. Just saying...

wstar · 08-12-2009, 11:14 AM

I haven't had any noticeable oil burn to date that I'm aware of. Dipstick stays constant under a given set of checking conditions throughout the life of an oil change for me so far. I'll be changing my oil again today, so I'll get another double-check on this before I drain.

No you should'nt have to top off your oil this often. My MX5 is a "revvy" motor but it does not consume anyoil, of course I don't rev to redline some here do all the time.

I check my oil everytime I fill up gas. You guys should make it a habbit.

You need to give it time to settle.

One of the best times to check oil is first thing in the morning.
The car has sat over night, the engine is cold, all of the oil has settled down into the pan.
