Replying to: motoguy128 (Mar 31, 2008 6:42 am) Like you, I have run regular gas in vehicles stating "use premium fuel only" (Mini Cooper, Harley Davidson bikes, etc)., and never had an issue. It may have affected the mileage and performance, but I didn't notice any MPG reduction (wasn't really looking, to be honest), and I don't drive that close to the "edge", so I didn't see any performance reduction. But, each to his own, I guess...

Replying to: busiris (Mar 31, 2008 10:31 am) a wives tale. the fact is, all high compression engines are susceptible to preignition of fuel in the combustion chamber. a higher octane fuel with a lower anti knock index (AKI) will prevent it. Knock, ping, run-on, performance and other things depend on a lot of factors, but for high compression engines, ie high performance, the biggest one is the quality of the fuel. It's really kind of simple, your not going to ruin your car by running cheap gas in it, though you will likely cause the formation of deposits on your valves and other parts and reduce performance and millage. But, buying a performance version of a car (which is all the V-6 variants are) and then putting cheap gas in it to save $4 per tank is like putting ketchup on prime rib instead of steak sauce cause its cheaper. |

Cheap gas is a different issue than octane. Although I've put every brand possible in my cars and motorcycles and never noticed any real difference in performance and never had any significant deposits in my engine that I was aware of. The only issue I've had is the in remote locations the gas might have been a little old or higher in moisture, but that is unavoidble in BFE. Also remember that typically, ALL gasoline comes from a regional distribution point. This gasoline comes by pipline from any number of different refineries. The tanker truck for that typical brand, dumps in a small barrell of their partcular additive formula and fills it up. Similarly to help understand oil prices, there in no direct link from the oil drilling ot the refinery. A Shell oil rig will fill an ocean tanker which unloads to a pipeline or storage facility. The refinery buys whatever grade crude oil they need on the open market. The exploration, drilling, ocen transport, storage, refining, storage, transport by truck and service station are all related, but indirectly linked. So buy fule wherever you want, the only difference is the additive package they toss in there (a minimum amount of detergents are required by law) and how rapidly that particular station turns over their tanks and how well they maintain their equipment. For octane, just check the manual. Most cars that recommend premium will also state than regular 87 octane is acceptable and will only results in reduced performance and possible reduced mileage in some cases. I beleive Toyotas 2.5L V6 is this way. My BMW motorcycle states the rated engine HP output for both 91 octane and 89 octane. |

Replying to: motoguy128 (Mar 31, 2008 6:42 am) Higher octane gasolines burn slower, their flame propagation is slowed down compared to lower octanes. This was required on older engines which were used at high RPMs and high power duty applicatons. Those application required much timing advance at higher RPMs and loads and thus, a slower burning fuel. Most drivers that I know never exceed 3 - 3500 RPMs during their whole lives of driving. For such drivers the 87 octane should be perfectly sufficient and, since for such driving slower flame propagation is not an issue, the gas mileage should not be effected. For those who like to run up to the redline and do hard uphill, high RPM pulls, the premium gas brings higher performance and, at those RPMs and loads you could possibly see the gas mileage adversely effected. But, when your foot is on the floor at 6K RPM, is it really an issue to consider fuel economy? You are probably running way below 10 MPG under such driving conditions. For me, when I drive my wife's '07 3.5 SE on our home, winding, hilly Sierra roads, we fill up with premium. But, then again, I drive at redline much having decades of track racing experience. When she is doing her normal driving patterns, (never exceeding 3K RPM) we're using regular. Anything else would be wasted money for her driving conditions. |

I just bought a 2007 Nissan Altima 3.5SE on Sat, May 10, 2008. I noticed when I start the car in the morning or park it and then start it up again let's say 5 minutes later after coming out of wherever I am going, the car will make a noise after I put it in drive and press the pedal to accelerate. I took it in this afternoon to have the service department listen to it and they said most likely it was an ABS self check(nothing to worry about). They said they have never heard the sound in other cars this loud. Should I have them really take a look at this or do I need to just take there advice and not worry about it? Thank you, Jeff

I was vaccuming my Altima today and I tried adjusting the seat foward and it wouldn't move. So then I tried sitting in it and then adjusting it and it's stuck! Anyone else have this problem?

Replying to: lauf (May 22, 2008 1:51 pm) When I took it to the dealer, they didn't find anything wrong with it. I asked them to call head office to inquire and to my surprise they called me back to re-check the seats. They found the problem. It was very simple, at least for my car. There was a screw that was protruding and getting in the way of the track. All they had to do was screw it down all the way. As simple as that. Have them check this. Good luck! |

| I bought my 07 Nissan Altima Hybrid in October 2007. It has been care free. However, the "unlock" logo on the "power door lock switch" is not lighted since it was new. Only the "lock" logo is lighted. Is this normal? I asked the dealer when I had my oil change. He checked few new cars, and said others are like that. Don't seem right to me. | |
