How often to change oil?

[jmatta]

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.
