How often to change oil?

[wawa]

I used to have Motul 0-40 with Ester in my MR2. Good or not for the Boxster? I'm Canadian and will run the car all winter long. -20C or even -30C is usual here.

The first choice should be 10W40 year round use. At least summer. If you are in a realy cold climate, 5W40 for winter. If you can't get 10 weight, just go with 5 weight. 0 is not recomended. These engines run very hot so stay with 40 or higher.

WRONG. I am not aware of a single Porsche approved 10W40 oil.

I change my oil once a year in the fall after around 2500 to 3000 miles; Castrol Syntec 10W40 is my oil of choice. LN Engineering, Jake Raby and JFP in PA all recommend oils other than Mobil 1 0W40, for obvious breakdown characteristics.

My '02 S with 21k on the clock has no start up noise or other issues.

Not to get into an oil debate, but I wouldn't put Mobil 1 in my lawn tractor.

You need to read-up on L&N's recommendations, because your statement above is inaccurate, at best.

You need to drive your Boxster more! 21,000 miles in 9 years? That's crazy. Olive Oil would hold up well in that environment.

My Toro lawnmower is +18 years old. Only lawn mower I've ever owned. I wish it would die, so I can justify buying a new one, but it won't. Still starts on the first pull. I've used Mobil and Red Line in it.

They way I have been doing it for years, is 3,000 miles or 3 months which ever comes first, and that is with all my vehicles. and as for which oil to use i use Mobile 1.
But everyone has their own opinion.

5k-7k miles, or twice a year, whenever i can get it to the shop.
