Hi everyone, I have some info that may be very helpful to all VQ35DE owners. Everyone seems to have different ideas about why the Q likes to drink up the oil, but i have researched this engine for a few years and i believe to have found the real problem. It turns out to be the catalytic converters in our cars...G35 has 4 cats. Read the screen shot i have attached. Want to learn even more about the V35? Go here: http://mywikimotors.com/vq35de/
I hope this helps all and if you have a low mile g35 you should take action and fix the problem before you find your self ordering a new engine. Have a good day!
You have any other proof besides an post you read online?
I'll wait for other members to chime in to further add proof to refute this statement.
I have no problem accepting that its ****, but lets see what happens. I'm trying to verify the legitness of the website as of now. Just go to it and look around...they seem to have accurate info on all the engines.
I also heard the inside of the cats disintegrate and the engine sucks the air back in with debris causing the rings to wear
What I don't get is what octane has anything to do with it especially for cars that start burning early??? Is there really that big of a different between 89 and 91 to cause the inside of engine to wear?
Plenty of 2004 6 speeds burn oil but the focus is only on the 05/06s...why is that??
Total and complete bullsh!t and so much fail in the original post I want to punch my laptop screen. 4 cats??? Where the fvck are the 2 I can't see, up my azz? And after 7.5 years of owning my car and being a member of this forum, octane levels have no effect on OC that I can confirm. Aaron might be on to something with the cat disintegration but that's not the main cause. Plenty of members have experienced OC after running nothing but high octane fuel for the life of the car and I'm one of them and have a 5AT not the revup.
The issue here is the crappy rings that Nissan installed in our motors. This has been discussed ad nauseum on here and OP if you had done some reading before you started this thread you would realize that after 14 years of G's existing you don't have the magic answer that we are all missing to the "Why do VQ35 motors burn oil?" question. Please don't post this kind of BS again. I appreciate the desire to help but it's misinformation like this on here that soils the reputation of the forum and steers potential new members elsewhere when they read this kind of heresay that they know is crap.
He seems to talk about the cats and a recall they had a while back, but the comments seem to disagree with the cat matter causing the oil consumtion.
Total BS
My previous 06 G35 6 speed manual sometimes used a qt of oil per 1000mi.
I used 87 octane on its 171796 miles when I traded it in for my present 2012 G37S
Never had any problem with the catalytic convertors on either vehicle.
Still use regular 87 octane.
Nothing that Jose posted at the top of this page is true! Oil consumption is caused by oil ring failure, nothing else. I often call them "Cheap Chinese Oil Rings" but that's just my sense of humor and my not be totally true. Gary
I only had a SES light for an EVAP problem, nothing serious and have used 91 octane since I got my car with 77k miles on it. Never a cat problem either...I agree with the piston rings issues as being the main problem...Guess we will never know if it was just soft metal or something else that caused them to wear
My engine has 220k on it now and I still have the original clutch (unless it was replaced before I got the car under 77k) so not sure which one will go first. I have been reading the VK56 swap threads and it gets me thinking !!! Since my car is only worth like 3k I might as well have fun with it, not really worth selling it at this point
