I have a 2007 Nissan Altima 2.5 SL with the same noise when the car is cold or sitting a while. I replaced the engine oil with Mobile 1 and also added in a bottle of Lucas oil and now the noise is very low when I cold start. I don't know why I have to use any additives to help to remove the noise when the engine is cold.
Maybe an engine recall coming? Please let me know.

its not a problem with the engine, it the ecm. It just needs reprogrammed. that is, if you bought your car in california. it may also be whats affecting your gas milage

do they adhere to california emission standards? If they do, I'd deffinitly ask the dealer about it. there is a known probem with the altima that are built for those standards with cold start up. Nissan has a service bullitan out about it. As I said, the cure is very simple. they just need to update the ecm. check this link that townboy325 put in his post.

I got my 2.5 SL about a month ago and go about 650 miles on it so far. I'm driving work about 5 miles locally with lots of stop sign (about 10). I'm getting 20.
sellcar, did you have a dealer to check your engine? I wonder the result.

My 2007 3.5 SE with 3,000 miles got 24.3 MPG on its last tank neck-to-neck after driving just 222 miles--mostly highway using the AC. On tanks where I've driven upwards of 300 or more miles mostly highway it's gotten low 26. It's MPG meter showed average of 28.2 one time, but usually stays in the high 26 range. Hasn't used a speck of oil--still 3/4 full since taking delivery on 12/21/06. As you can tell, I don't drive it very much--stay mostly in a 1990 Festiva 5 Spd I bought on 7/5/04 with 159,000 miles on it for $300--it now has 181,000 on it--get 39-41 MPG everytime I fill up. Changed timing belt and clutch for $750--I'm shooting for 200,000...

Question about mpg

I'm having 24 mpg from my calculation with 40% city and 60 highway with the new 2007 2.5S, is it abnormal? I always have AC on at low, and I'm not an aggressive driver.

I've read several places that the mpg will increase after you get over 2 or 3k. something about being programmed to run a richer fuel mixture to assist in break-in. not sure if its true though.
