Lynchmawb

Well I got a call from the dealship today and I get a new motor.... The trick is I don't know when its on backorder....

Cool! Glad they're taking care of you. This is a positive sign.

Just arrived at 13k after 2 consumption test. New Engine will arrive in 2weeks.

My engine was replaced at 17k... massive oil consumption. I didn't put the first 100-200 miles on the car originally, which are the most important, so I'm not sure how the initial break-in was done. (could have been test drove and beat to hell on a cold engine, and also could have been kept at steady RPM on a 100mile trip to the dealership by whoever delivered it). The new engine had 12 miles on it after the dealership was done with the swap... so I got to break the new engine in my way.

I've talked to several local people who know of others having the same issues though. This is definitely not isolated... and nobody is blowing anything out of proportion. Having your engine replaced because it's drinking oil like it's going out of style is NOT a fun thing to have happen on a brand new car.

All I know is if the new engine starts to develop an appetite for oil - I'll let it be the problem for someone else and find a new car. There would be no love lost.

"and also could have been kept at steady RPM on a 100mile trip to the dealership by whoever delivered it"

I think this was the problem with my 2006 OC 350. The dealer had to find the car I wanted in another state, and they drove it 450 miles to my dealership........ most likely all at one RPM and highway speed. Who knows, there are so many theories about the cause of this. I wish you the best with the new engine, I've been there and it's no fun. My 370 had 28 miles on it when I took delivery, so I too was able to break it in. So far so good, but I only have 12,800 miles on it right now. Time will tell.

The "normal and acceptable" oil useage I keep hearing is just nothing like I've ever experienced after 3 new vehicles.

First new car was a 2003 Corolla 1.8L 5-spd. Car used 1/2 quart every 5000 miles.

2007 Altima 3.5SE 6-spd. Car used 1 quart during the first 1000 miles and 1/2 quart per 5000 miles afterward.

The 2009 370Z 6-spd is exactly the same. With 19,000 miles on it, this car has used 1 quart during the first 1500 miles, and since then has used 1/2 quart every 5000 miles.

I've always used Castrol Syntec 0W-30 and per Blackstone used oil analysis, the Altima and Z have perfect wear trends. The Z and two previous cars are abused on a regular basis. Lots of redlining, etc. I am smart about it, though and the oil is ALWAYS changed at 5000 mile intervals. Never had a problem.

Strange thing is, I broke the Altima and Corolla in EXACTLY by the book. The Z I have driven like an ******* since I drove it off the lot.

Late,

My oil is right between the 2 holes in the dipstick. I put on a thousand miles since my last oil change so according to my owners manual it is good, although after i got my oil changed i don't know how high on the dip stick it was. So I guess I'll just watch it but I do't think its anything for me to worry about. Hell I hit my 3 month mark next month around this time so I wont get the full milage out of it. I have 7400 miles on my car i think if it was burning i would have known it by now. If anyone knows where on the dip stick the oils is around after a change let me know please.

If I got a new engine after 17K, I'd be ecstatic.

BTW, my engine consumes almost no oil at 3500 miles. I was very easy on the engine until 1200 mile break-in was done.

Why would you be ecstatic? You have to wait forever for the longblock to arrive, then you have to wait another week while they install it... then you have to go through the break-in process all over again... and then you have to leave your broken car at the dealership while they try to get parts to fix things that were jacked up with the swap.

Not my idea of enjoying a brand new sports car... but that's just me.

Warm engine and wait 15 minutes according to the manual. The manual says add some oil if it is below the lowest hole. I'm assuming this means leave it be if between the holes.

My Z is at the shop right now for oil comsumption. The dealer asked for reciepts from my last oil change. Told him I dont have any. They want to replace my engine also. So just waiting to find out if it will be under warranty. I havent done any major mods or whatever, so no worries there. Just over 18k on mine. Guess its a lesson learned though to check my oil regularly from now on.

My Z is at the dealer (8th day and counting) getting the replacement short block + a laundry list of other parts replaced after failing the oil consumption test. fortunately my '09 Z will essentially have a '10 engine. Mine was the first fail at my dealership. the problem started at 7500 miles. Break in was normal except the original 211 miles (those I have no idea) and by the book. During the oil consumption process, the engine scrammed once (electronic protection w/o power above 2500 rpm). No mods yet, waiting for this issue to be resolved. The tell-tale was 220-240 on the guage...before getting on the freeway. Dealer is taking their time since one more visit within 30 days of this issue and it triggers lemon law.

Just got my car back from the dealer. New short block and everything that goes in it was replaced. The tech spent a few extra days doing some shake out and retuning. I was definitely losing hp with the leaky seals and the car sounds (and smells) better. If you run with the ester oil, a tell tale sign of the ester oil consumption issue is that faint hint of 'french fries' smell in the garage, lol! Now for the painful 1500mi break in period...again. Looking forward to upgrading the exhaust and intakes after that.

Three weeks after buying my 01/09 Z in 05/10, I decided to check my oil for the first time at 485 miles (after oil temp hit 245 degrees, while outside was 59 degrees). Sure enough the dip stick was where hand book recommends adding oil. So I added 3/4 quarts. Today at 1048 miles I just added another 3/4's. Car normally runs at 220+ during break in, under 4000 revs.

I have the oil problem too. I bought mine last june and at about 3k mi it was in the shop as it went into limp mode, they replaced cam shaft actuators had the car for a week. I garaged the car with 6k on it for winter had the oil changed when i took it out of storage, have been back to dealer twice and both times I have had 1.25 qts of oil added the car has 7051 miles on it. Im getting a new motor but for the money I spent Im pretty upset.
