| Well Im getting a new engine. Dropped it off today and should have it back in a week or so. On 31K on the clock. Oil was below the lower dot. |
I'm missing something. A new engine @ only 31k miles????

Infiniti has a BS setup for the service department to go through before they will consider this. They go to the extent of not only making us prove it but them a deyailed estimate of the cost of a new engine? Really they make you call Infiniti and tell them how much it is going to cost to replace the effected components. With a block that has been run low the entire thing should be replaced. It is actually cheaper than replacing everything piece by piece.

That's a VH....It's not even the same thing in this case. The VH was an amazing engine but not efficient enough to meet the needs of modern cars. My J is the same way. It's fun it has a great note to its operation, but it's old outdated technology. Things are not the way they used to be but there are more pros than cons when it comes to advanced technology. An example of that is more than 4 fan speed setting, auto up windows, actual integration between the transmission and the dynamic control features.

I do not have actual numbers for the dipstick. You need to start with a fresh oil change and 6 qts of oil. When the car is cold and has sat for a while check the level. They are very sensitive to inclination and temperature. A check needs to be performed every 1,000 miles and documented. Any test you perform yourself will need to be repeated by the dealer (records and the such).
This is not acknowledgment of an issue just how the dealer evaluates what oil being lost under normal operating conditions. There is indeed an acceptable amount and most of these use a little as part of normal operation.

personal experience shared: I started reading about the consumption problems for this motor last year (I have a 2003 which, at the time, had maybe 30K on it). I had the oil/filter changed at a local Infiniti dealer and had driven it approximately 1,000 miles since that change, and decided to go out to the garage and check my oil level. Whoa - I was down to the bottom dot on the stick, so I grabbed a bottle of Valvoline 5/30 and poured it in - checked again (after waiting 5 min) and the dipstick was right at the top of the upper dot. So, over the course of the next 2750 miles, I am monitoring the oil level to see how much I use. I end up adding another 3/4 of a quart to bring it to the top dot.
Take it back to the same Infiniti dealer and they immediately agree to do the consumption test, as nearly 2 quarts/oil in 3750 miles is excessive for todays tight tolerance engines.
So, it's 1,000 miles into the test and I check the dip stick and the oil level is just below the top dot? WTF is up with that? At any rate, over the next 2750 miles I used "almost" a quart of oil -- more than acceptable for nearly 4,000 miles, especially the way I drive it. So -- why would this be? My STRONG hunch - 5 qts added vs 6 qts needed.
Most engines take 5 quarts of oil; the M45's take SIX. I would bet my paycheck to the techs that he only added 5 Qts that previous change, and so when I checked it and found it slightly over a qt down, I am SURE that was why. My M was NOT burning oil but the techs inability to count caused me to have a Malox Moment. So I told the service manager to be sure the techs check the levels on the M45's BEFORE they send the cars back out.
So, much ado about nothing. I now pop my hood and check my oil level before driving away. Bet they love seeing me do that in their delvery/inspection driveway.

The car is currently at 32k miles so now I just gotta wait and see on their decision.

I do not think I would go to that extreme, but as The00Dustin pointed out not all M45s have an issue with consumption and there really is not a vin range or production date linking them to the same production run.

| Rechecked oil level after 1500 more miles and level is BELOW the lower dot. This is the first non Toyota car I have owned in many years and none of them have ever used a drop of oil, ok maybe leaking oil after the 130k mark. My Wifes Sequouia has 94000mi and does not use any oil and I it has been changed the oil every 5000mi, I dont even check it between changes as it has never used any, I did buy it new. |
This is not something that is limited Infiniti in the least. Almost all of the European luxury sedans with 8 cylinder and larger engines have some measure of oil consumption and blue smoke at startup. Cadillacs and MBs used huge amounts of oil and their crankcase filling requirements reflected as such. One of my coworkers spent many years working at a large Caddy dealer and said the Northstar motor would easily burn through 3qts of oil between services.

Now after just three months of ownership I will be needing an engine! Is thier any other reason for this oil useage, maybe a PCV valve? I only hope they do a good job fixing it. Has anyone got Infiniti to buy back the cars with this issue? |

Now I have to deal with this crap, I expected to drive the car and enjoy it for many years, now I will have to get it fixed and live with a car could need a motor in another 35k! New2import did they at least give you a car to drive while yours was out of service for all that time. When you say a block is that include the cylinder heads or just the block with pistons? |
I don't know why you are getting so exasturbated over this.It's only a car, there is no need to get all hot and bothered. If you do have an oil consumption issue and your 7/70 powertrain warranty is still applicable your whole engine will be replaced. I have replaced a few of the early 06 M45 long block assembly and have never seen a repeat issue. The long block comes in a large box with the heads, block, and timing chain already installed. All the technician has to do is remove it from the car and swap the accessories, intake and exhaust system components.

This is insane for a modern day luxury car to get less than 35000 miles out of an engine!!! I will never buy anther Nissan product again if this is the type of crap they put out on the market and considering they have known about the problem for so long, shame on them. |
You really need to take a deep breathe and crack open a nice bottle of wine and enjoy the summer. Life is too short. I too tend to get very worked up over things that I actually have no control over and it is allot of work to get that mad at inanimate objects.
If this is the only reason that you loath this car that is seems like you are not taking in the whole picture. This is a great car and as many of the members here rave about them. The M45 is an amazing car for both its performance and technological aspects. Don't stress it too much and really the dealer will be much more willing to help you if you are not threatening, it's human nature.
As the second owner of the car you have NO shot getting Nissan to buy your car back.Plain and simply the law is not in your favor. The lemon law criteria in most states applies solely to the first owner. If your car is actually burning oil it will get replaced if it, and that is that. ( http://www.800helpfla.com/lemo....html )

| Does anyone know what the maximum oil usage that Infiniti considers normal is? I don't see any reason to have them do a consumption test if my car isn't really using that much oil. I believe it is using quart every 4000 miles, but I am not yet positive on that. |
More than 1 qt every 1000 miles is the "overly high usage" criterion that Infiniti uses to make decisions about the engine.
My 2003 M45 needs about 1/4 to 1/2 qt every 1750 miles. Since I change the oil at the 3750 mark (without adding anything), it is effectively going through less than 1 qt between oil changes.

Steve , I hate to tell you this, especially on my first and maybe only post but I think your caddie friend was only trying to make you feel better.
You can check this yourself..the Cadillac CTS-V forums mention virtually nothing about oil consumption such as mentioned in this thread, I have not ever read of a motor needing to be replaced, I'm not saying this hasn't happened but it must be ultra rare..and your talking about a 550HP V-8 motor in the 09. Earlier years with the 400+hp CTS-V, I personally read more whining about the CTS-V Cologne smell then about oil issues 
..they don't have the problem and zero blue smoke issues and they are quite fanatical car owners and for good reasons, you'd see huge threads if there was anything mechanical about that CTS engine or for that matter the car itself.

Honestly I think that is the first time I have gotten called out in such a manner. I agree since Caddy started with their Euro style designing (early cts) their quality. I am talking about the Northstar (forgive my lack of knowledge on the production run) from the previous line. The VK45 in the M is a fairly old drivetrain and has not been significantly updated since the removal of EGR valves. The VK50 resolves the issues of its predecessor.
I really should have been more specific and I did indeed make a judgemental statement about something I know very little about. Although of the ones I have driven and serviced are not to my personal liking. I however am not shy about my bias.
I would still like to drive a cts-v but I have had a chance to drive an xlr-v (trade in on a used M6) and although it looks flashy I would take a Vette over it, the gauges are pretty interesting though. It feels numb. I just do not prefer the American luxury brands interior styling, and their retained value.
The do make a powerful V8 though that is one thing they do have going for them. I think the CTS is a little too small for the same reasons as the IS.
