Replying to: robikjan (Jan 07, 2005 5:36 pm) Robikjan, my manual 2004 I35 and my dealer recommended regular gas. I tried super a few times (which is recommended for "improved" performance) and I did not notice any improvement. Stay with regular! Replies to this message: jhinsc (Jan 16, 2005 8:24 pm)

Replying to: avt1 (Jan 12, 2005 12:53 pm) The Infiniti web site indicates premium fuel as the fuel requirement under specifications for the 2004 I35. I have a 2002 I35, which is identical mechanically as the 2004, and the manual states on page 10-3; "Use unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (Research octane number 96). If unleaded premium is not available, unleaded regular with an octane rating of at least 87 AKI (Research octane number 91) can be used. However, for maximum performance, the use of unleaded premium gasoline is recommended." So, nowhere in any documentation from Infiniti is regular or mid-grade fuel recommended. If premium is not available, then it's ok to use regular as a substitute, but they make a point that the recommended fuel is premium grade.

Replying to: robikjan (Jan 07, 2005 5:36 pm) When I bought my car my dealer told me to use mid grade but the car kept knocking whenever under strain of hills and such. But the owners manual says 91 octane and that means premium. I now just fill up with the premium and have had no more problems with the knocking. If you aren't knocking at regular or mid-grade go for it, but I live in an area with rolling hills and really noticed the difference when I switched it to the recommended gas of 91 octane. Some cars just need the extra octane for their performance, my husband's Audi also requires premium. Replies to this message: delmar1 (Jun 05, 2005 8:51 pm)

Replying to: yankeebelle (Mar 03, 2005 8:46 am) Beyond knocking....does anyone notice any MPG improvement by using premium versus regular? Some cars I understand have improved MPG by using premium..hench making up for the price difference of the fuel.   Three old arguments: 1) Knocking / pinging (I gather that is depends on hills or other strains) 2) Performance (doesn't sound like it from others here) 3) MPG (no mention here on the boards)

#19 of 32 Cabin Filter by seabush Sep 16, 2005 (7:58 pm)
FYI. The Nissan Maxima (2000-2003) and the I30/I35 (2000-) use the same cabin filter. The part # is 999M1-VP004. I just picked up a filter for my 2004 I35 at the local Nissan dealership for $50.
#20 of 32 Extra kick for the 04 I35? by lovethat35 Oct 20, 2005 (6:26 pm)
So I appreciate the I35 most for its power, and luxury(and price) rolled into one. However, I am a lead foot driver, and love that extra kick. I already added a K&N air filter, but Im wondering if anyone knows any simple ways to improve the performance on this particular model, without messing up the warranty(if possible). It seems there is very little after-market products offered for this car. I looked at some cold air intakes, but the only one I could find was from Canade, being offered on ebay. Anyone added any simple things(that can be US bought) they can share to give this car some added kick?

Replying to: yankeebelle (Aug 22, 2005 12:06 pm) I just pulled the cover off and there is no filter there to change. Any idea of why that would be?
#22 of 32 No 4 wheel alignment needed by yankeebelle Mar 26, 2006 (12:25 pm)
I just used a non-dealer tire shop and found out something interesting. The I35 only needs a 2 wheel alignment. My dealer has been charging me for a 4 wheel alignment but they cannot adjust the rear, there are no adjustments. My husband did some digging and found out that parent company Nissan tells the dealers to "do" the 4 wheel as a way of checking that the car is still square, in other words they are charging you double to see if your car has been in an accident. We are furious. We've paid for work they aren't doing because no one told us it can't be adjusted in the rear and it isn't in the manual. So next time you need an alignment, save some money and get what you are paying for, a 2 wheel alignment.
