With my Boxster? No.

But Amsoil is very well respected in the offroad motorcycle world, plenty of racers use Amsoil with great results. I believe it's a group 4 base oil with a decent additive package. As JFP stated, there are probably better choices for the Boxster.

I haven't tried Amsoil yet because nobody around here sells it and I'm not going to "mail order" motor oil. They market their 0W/40 as snowmobile and ATV oil. It shouldn't be a problem, but figured it was worth noting. I've had good luck with Royal Purple products and I can actually go down to Advance Auto and buy a case so I'm sticking with them.

I've been using Amsoil in my regular cars for years and am happy w/ it.

I'd be interested in hearing which oil is better for P-cars that cost less.

And here is some related info about engine oil:

In my shop, we currently use Castrol Syntec 10W-40 as our standard recommendation for the M96/97 engines. Years back, we used to use a couple of grades of Mobil 1 products; however, post acquisition by Exxon, we started seeing the used oil analysis really crap out on several grades, most notably the 0W-40 and 15W-50 (widely used in air cooled Porsches). At the same time, some grades of Mobil 1 (most notably the 15W-50) lost all the ACEA ratings (ever since API moved from being the “gatekeeper” on things such as oil specs and ratings to a marketing and public relations role, leaving the manufacturer’s to “self police” their products; we stopped looking at all API ratings and only look at ACEA specs, which are both stringent and require independent verification). We started testing other brands and eventually settled on the Castrol Syntec line. On-going UoA’s have continued to support this choice.

As for pricing, one of the best sources for Castrol Syntec, if you are not a dealer or shop, is your local Wal-Mart. Last week I saw 5 quart containers of 10W-40 Syntec on the shelf at two local Wal-Marts for $22…………….

I just did an oil change last week and can assure you that Mobil 1 has all the ACEA ratings listed as well as the API ratings right on the bottle.

What grade of Mobil 1? Not all have lost their ACEA ratings, but others (like the 15W-50) have. Mobil 1 tech has confirmed this to us in writing. Porsche "supposedly" forced them to resubmit 0W-40 (which they had to do multiple times before it passed) to get A3, B3, B4 ratings from ACEA…………….

Mobil 1 ain’t what it used to be………………

I used Mobil 1 5W/30 and a Wix filter.
