Oil for 2000 Boxster S

[Perfectlap]

if you are asking for opinions on that brand you might want to do a search. Mobil 0-40 may be the factory fill but many, including some experts familiar with the Boxsters engine issues, are quiet vocal about disagreeing that this brand provides the best protection. I use the Castrol synthetic, Autozone usually has a 5 quart deal for about $27 where they toss in a free filter which is at least a $12 value. I try to change the oil every 7 months so I look for deals on oil.

I have read extensively on the subject and despite what many on this forum have to say, the petroleum experts (not the car owners) believe that Mobil 1 0W40 provides more than adequate protection for a boxer engine. I have used Mobil 1 0W40 for several years now with excellent results.
The best way to start a fire storm on this forum is bring up the subject of oil -- followed closely by the choice of tires.

true it is usually a heated debate. But I think a new Boxster owner should be aware of the wide range of opinions of Mobil 1 for this car. Well in at least that there are other factory approved oils with much less controversy surrounding them.
