If i can just find someone with oil purchase receipts that they will let me borrow in so cal, i would really apretiate it and of course with a generouse tip. I rather pay a lil for some peices of receipts then be paying thousands for a new lower engine.. Im seriouse.

FYI I was told that my motor was a handbuilt engine from Japan. I did see the shipping invoice and the shipping cost was rediculous. Most engines that are not working are made in the good old state of New Mexico. Ask your dealers where the motor came from. Infiniti of Chantilly doesnt mess around, it took 4 weeks to get the motor (drove the then new G35X while I waited), but it was strong from the first mile I drove it. The car put down 406RWHP @8psi on a dyna pack dyno and runs with a G35 APSTT that put down 369 on a dyno dynamics @9psi. I think its becaue the motor was built right with less forgiveness in the tolerences.

it sucks, but all this time you spend driving like a granny, buy the time you are on your 3rd motor its 2 years down the road and you still dont know the limits of your car. Screw that, if it burns oil, go get a new motor.... but the time you spend with it should be enjoyable.

Half a quart low (between H and L marks) before I changed the oil.

I would say that's in line with what I would be expecting from a DD sport car that's occasionally driven hard.

Broken in using Nissan OEM oil until 1700 miles (again, I know- nice seeing all the little bits of metal in the oil) using Nissan guidelines under 4500rpm never WOT. After 1600/1700 drove it normal.

On a lighter note I look forward to getting a 07 350z better engine hopefully. I am just going to wait until 07 get a little bit cheaper maybe by the summer.

They kept the car for a day. Did some "testing" and called me with the news. Nissan has ordered a new engine, and I'm supposed to get the car back this Friday. We'll see how that goes.

Anyways, thanks for all the forum info. It's a great help!!

Thanks for the UOA. It looks better in terms of wear. Iron and Copper have stabilized at 10ppm, while the rest of your metals have all dropped to 3ppm or less. I would still like to see 0ppm of chromium, though, given the fuel dilution amount.

Fuel dilution spiked back up this sample, which lowered your flash point of the oil. Surprisingly, it stayed in grade, though. I think PP handles fuel dilution quite well.

The moly raised in this sample, which was unexpected since you're using the same oil as last time. Maybe PP changed their formula slightly to include more moly, maybe the change is within a standard deviation. I don't know, but it is interesting.

Overall, it looks good and I'm sure you're glad not to be burning any oil off. Looks like another good V2 engine!

Will
