    Looking to purchase a 05-08 sts, motor questions?

    I have my eye on a few cars right now, I'm having a hard time deciding between the v6 and v8? Is one more trouble free/reliable than the other? Thanks

    I have the northstar v8 and boy is it fun. If you like your car to have pep then the v8 is the way to go. You will not regret it.

    Northstar or nothing. Something about a V8 that I just love. As others said, MPG's won't be a big difference between the two.

    Another vote for the NorthStar here. GM finally got it right in 2005.

    If you get a V-6 your next post will be asking where to get power mods.

    I've got an 06 STS with the v6 with 75,000 miles and am doing an oil useage test through my dealer to see if GM will relace/rebuild the engine. I'm using 1 quart every 700 miles!! I buy Mobil1 by the gallon to keep my STS and my wife's SRX filled. Hers has the same problem but we haven't done the test yet. I'd agree with the posts on the v8, although I've never driven one. I get 20-21 mpg most of the time and have never gotten above 22.

    chachd, My 06 STS V-6 also was using 1qt. of oil every 760 miles. Cadillac while under warrenty replaced piston rings. Now 40k miles later uses zero oil between changes, ( 10k miles). Danny
