Everyone: Check Your Oil!
#932
Hmmm.. I was looking to purchase a 05'06 G35 Coupe 6mt but this thread is throwing me off... My cousin leased a 05 coupe auto and never had any issues.
How can I tell if the 05-06 G35 I'm about to purchase is having this problem? Is there anyway I can check through VIN #'s what work Infiniti has done to the Vehicle? Will Carfax show this? I might just hold off till next year and get the G37... Hopefully no oil consumptions with the new engine..

I can definitely relate to this thread, about 8 months ago same thing I heard the rattling come home from the beach I new I had to go get my oil changed. As soon as I hit six gear going 65mph all of a sudden there go my pistons . Long story short pretty much blew the engine got home a 6:30 in the morning and the dealership covered it with warranty. So yea, my recommendation is always change your oil!

Heavier weight oil?
Has anyone used a 10w-30 oil? I used to have the same problem with my Integra GSR (lost 1qt/1000mi). I went with a heavier weight and found less oil lost. This could be due to the loss of fluidity of the oil, lowering the amount of oil able to make it past the piston rings.
Anyways, I was having similar problems with my 03 G35, so I put 10w-30 and I'm gonna keep track as to whether it helps to reduce oil consumption or not. I know some people live in the northeast, so using heavier weight oils might be a bigger issue. And I know some people can't stand the thought of a heavier viscosity oil "robbing" horsepower, but if it saves and engine, then mission accomplished.

It's a game the US auto manufactures use to meet their CAFE (Corporate Average Fuel Economy) Standards that were passed by US Congress.
When they don't meet those, there's significant fines involved. So, they spec 5w-20 to help their stated mpg number, reduce fines and really don't care how long the engine lasts.
In fact it's a win win for them. Less CAFE fines and consumers buying vehicles more often b/c the engine fails sooner than it should in the long run and of course, fails beyond their warranty coverage.
I'd never use that weight regardless if it's recommended and I was planning on keeping that vehicle for years and years.
Long reading, but good info about 5w-20. Ignore the slight sales pitch selling their 5w-50, though interesting as to why 5w-50.
Still good hard core facts about that weak-sauce multigrade oil in general and why some manufactures spec it.
