I've had a 2012 7th gen maxima for 4 months now & barely had an engine oil & oil filter changed. As well just today I change the intake air filter for a K&N filter which I feel pretty satisfied with, but I didn't see much improvement. So I was thinking of using Seafoam, but I haven't been able to find the vacuum hose myself & I was wondering if anybody can post a picture showing where it is at. Thanks

 

Anybody?

 

Only 2 years old and wanting to sea foam?
I say not necessary.

If the 7th gen is like most cars you can use the break booster hose, but I have a 4th gen so it's just a guess since no one else has chimed in yet.

 

Where would it be located?

 

The filter will not give you any noticeable improvement. Your car is pretty new...I also do not think that using Seafoam is necessary.

 

One thing I did forget to say is that it is a used car & the previous owner had put 160,000 or so miles into it. So far I've only added 21,893 miles to it.
I do know that as well about the filter, but I was expecting a tiny bit of change which I did actually. I saw a lot more difference than just a bit on my gas mileage lol since I got that K&N filter.

 

21k miles in 4 months?!?!? Holy crap! I thought I had a crazy commute! That's pretty high mileage on such a new car. I am curious to see how your max is holding up? Had any issues thus far?

 

180,000 milage on a 2 year old car??? That about 500 miles a day. The odometer is wrong or the previous owner loved his car so much he never got out of it. That would be changing the oil three times a month or more.

 

No I haven't had any issues and the car is holding up pretty good actually. I live in Texas I be going to a lot of places that are far. So that why I have much miles on it.

 

Actually I don't change the oil every three times a month. I change it every four months.
I still haven't had any issues so far like I said before. The car is running fine from the looks of it. Not just that at night I be racing sometimes, but other than that the car is good.

 

Just to say as well I check the car every time I run it. I check it at least twice a week
