I'm due for an oil change & tires I currently have bf goodrich g-force sport tires. I drive 100miles a day, interstate, 5 days a week year around and some in town. don't drive real hard but I push it a little. also my oil guy has a synthetic mobil 0-40 that he says is porsche approved. the tires I have were fine other than being very noisey. would like to have your thoughts on both.
2002 base, tiptronic. 2.7 I'm located in north Alabama.
Thanks!

If you do a thread search on "tire recommendations" you'll find that opinions abound.

I spent $1200 on Michelin PS2's last time to own what most call "the best." Now I'm broke and I'll probably buy Hankook Ventus V12's at half the price installed which are said to be just as good.

Everyone will have their favorite brand though.

Now to oil recommendations:

Another very hotly debated topic, both for weights (0W40 or 5W40????) and brands. Most run Mobil 1 0W40 because it's factory fill, and change it once a year or every 7500 miles, whichever comes first.

I bought Royal Purple at nearly twice the price per quart due to an article I read on motor wear comparing brands.

With both tires and oil, the opinions will be o-plenty and you'll be dizzy by them all.

Search the forum and you'll learn more than you ever wanted to know about both.

Me, 5-40 Castrol or Mobile 1. I have used Castrol for the past 30 years on most of my cars. Tires, I recommend Falken 912's. Very nice smooth ride and perfect for warm and wet climates...terrible in snow country. I just put them on my 2000 Boxster S in November. Love em. $625 installed from Discount Tires and I have 18" on mine and the backs are larger than the fronts.

100 miles a day...I'm lucky if I get that in a week or so. You will find many opinions on tires if you search...as far as oil, please read the following information on LN's website; the engine you save, may be your own.

FWIW, I run Castrol Syntec 10W40 and only drive in moderate to warm temps.

Considering your commute distance and moderate behavior, I'd suggest paying attention to the treadwear rating on the tires that you are considering. A slightly harder compound tire will sacrifice some grip for longer life. Which sounds like it might be of some benefit to you.

As for oil, in addition to some thorough research, consider change intervals more frequent than Porsche recommends.

Here's a whole web site devoted to arguing about oil:

http://www.bobistheoilguy.com

They have some good threads about Royal Purple and Amsol as well as some significant Mobil 1 bashing.

That article you posted, jmatta, is a good one. Made my head spin a bit as it's terribly technical, but knowing what to look for in the certifications is good knowledge.
