    Just think! You will probably be burning some of that synthetic oil every time you drive since the N* seems to love oil consumption. Be sure to check the oil once a week. See another forum discussions and the archive if you are not up to date on the oil consumption discussions and WOT recommendations.
    Good Luck and pedal down!

    Keep in mind that $5/qt synthetic is not needed. Conventional dino oil at $1 - $1.50/qt is what is spec'd by the GM.

    The "regular" oil here is now $2.50 a quart, so I decided to spring for the synthetic.

    Not at WalMart. You can get a 5 quart jug of dino oil, for $7 - $8.00. Unless you drive in extreme heat (above 100 degrees), or in extreme cold (below 0 degrees) constantly, there is zero benefit with synthetic oil. Save your money, and use conventional oil.

    You can buy a 5 gallon jug of Mobil 1 at Wally World for $20 and change. That's a bit more than $4 a quart.

    Heck with all of that, I just wait for a coupon from one of the parts stores. I got a case (12qt) of valvoline for 69c a quart last oil change I did.

    You can use $8.00 a quart oil if you want, and it means nothing with a crappy filter. Best bang for your buck seems to be using a high-quality conventional oil at $1.xx a quart or whatever's on sale, and using a high-quality filter like a Purolator PureONE or Premium Plus, Wix, AC-Delco, or Mobil1. They flow better, are constructed better, and filter better than cheap filters, and almost anything is better than a Fram. Filters are inexpensive, and even a great one like a Purolator PureONE is still only a $5 or $6 part as opposed to a $3 one. Money well spent on filters, but I still don't see any benefits from synthetics.

    Re: Well, changed the oil....

    I dont see how you people above said that "synthetic does nothing unless severly cold or blazing hot like Arizona summers". That is entirely false. Conventional oils break down and leave sludge deposits after even 1,500 miles sometimes. Especially with a lot of WOT usage. I use Mobil 1 10w-30 synthetic in my 4.0 northstar. It uses a lot of it, or,erm, leaks it out; but it will do taht with any oil i put in it. It seems a lot smoother running in the cold mornings in PA.

    Do what you want, but I would run synthetic in the northstars especially with the chains, they whip the **** out of oil.

    Re: Well, changed the oil....

    You are terribly misinformed.

    The chains don't whip anything. Besides oil have an anti foaming agent in them. As for sludge, I stuck a bore scope in my cam cover at 100K, no sludge. I pulled the oil pan off my wifes '96 Bonneville to replace a gasket at 115K, no sludge.

    Start ups below -20 or pulling a trailer across Death Valley is exactly where synthetics are superior to conventional oil. It sounds like you have fallen victim to the synthetic marketing gurus. Use it if you like, but know the facts. Synthetic oil is not superior for the type of driving you and I are doing. It is superior in very very frigid weather and will stand up to much higher tempuratures than conventional oil. Hotter than your engine will ever see (hopefully). Your engine will not out last mine. It is not cleaner than mine. It will not run better than mine. Your wallet however, will be a little lighter than mine.
