oil for a new england summer?

[stumpjumper]

I've got a case of m1 0w-40 left because that's what my audi gets, i was wondering if i should use something more viscous for the boxster as it's engine gets a bit warmer judging by the water temp guage

anybody have any opinions? it's supposed to be a hot summer and it's a black car, should I just use the 0w-40 I've got or go higher? I figure I'll change it again before it gets cold if that matters.

thanks,

tom

Porsche recommends M1 0w-40. Color of car doesn't matter.

Porsche approves many oils, the only time it specifies which weight to use it says to pick 0w-X oils is when it's -12F or below. Since it's highly unlikely that it will drop below 50F during the summer that doesn't really apply.

I always use mobile 1 race spec in my porsches, as soon as I buy a porsche (second hand that is) I put in the top of the range mobile stuff. You can get it from halfords but for the 8 litres you need it will set you back between £80-£100.

I believe its rated at 0w-40

I have a 98 2.5 with almost 80K my last 3 oil changes were with amsoil 10w-40 Is this a good thing? or should I go to a 0w-40???
