I just bought a 2006 G35 6mt 9 days ago... and have a question about mileage. I am in the break-in process right now, and am going to follow it properly... Then I am going to drive the car in a normal manner (drive is spirited, like it is meant to be driven, but not beat on the car).

My question: How long / How many miles can I expect to get out of this engine? I will religiously change the oil every 2500 - 3000 miles, will only be using 91 or 93 octane fuel, and will be garage kept. I am not talking about clutches or brakes... but how many miles until the engine will start to give up?

The reason: I currently drive 65 miles per day (highway) to work and back and go on 8 hours trips on the weekend sometimes. I financed the car for 6 years. I want to make sure the car is still running when I pay it off

Thanks for any responses or experiences with a high mileage G

 

Should be fine for your intended use. While I don't think there are a lot of G's with a ton of miles on them, I do know that the VQ engine in the Maxima has seen 200,000+ miles for a good number of owners. Treat it well, as you intend to, and you should get some high miles out of this engine.

I haven't read any posts on here of people who have lost the G's engine... ...other than the cases where people have gone forced-induction.

 

Nissan engines are pretty solid. The engine itself will probably go over 200k miles. But the transmission isn't the best in the world, so it would probably go before the engine does. I'm sure you'll be sick of the car and ready for a change before it dies.


As an added question to this, my old Nissan 240 had a timing chain, does this engine use a chain or belt?

 

If it's well cared for like you say, 3K oil/filter, all regular maintenance, you should get will over 250K to 350K. Most people don't take care of there stuff and they die early.

 

Excellent... this is the type of thing I wanted to hear!!! THANKS.

 

It's all in how you take care of it. My last ride was a GM 4-banger built 10 years ago, driven hard from day 1, engine hadn't lost a step at 140K miles. 200K for the VQ should be no sweat.

 

200 to 300k is not a problem in a well maintained VQ

 

Wtf are you smoking... The vq35 is a weak peice of ****... I probably should build it with bolt ons

 

ummmmm....I'm not sure if I'm supposed to take this post seriously or not. I think it's a great engine.

 

77k and still going strong!

 

The highway miles don't mean much to a well broken-in engine. You should vary your speed/RPM's on the highway during the break-in period, however.

 

I am verying the engine RPM's on the highways... mostly because traffic has sucked lately... but if I take long road trip... should I just change gear often (between 5th and 6th) to vary the rpm's... or literally speed up and slow down to vary them?

 

My '91 300ZX with a VG30DE engine has 178,000 miles on it- still super smooth and doesn't drink any oil. I hope my G35's VQ does as well. One poster asked if the VQ has a timing chain or belt. It has a timing chain. My 300ZX has a belt which has to be replaced every 60,000 miles.

 

What matters is engine speed, so, just switching gears helps a bit. But if you're going the same speed and just going between 5th and 6th, you aren't varying the rpm's much. Its a good idea to speed up and slow down a bit too.
