what oil should i be using? im about to do a service and wondered what is best? im in the uk

 

Huge debate there.... I use Motul

A

 

This will be good. Normally I have to go to Renntech to watch these fireworks! Most use Mobil 1 0W-40, sometimes also referred to as Mobil water.

I now use 15W-50 during the summer. That's enough to get things started

 

Mobil 1. Why mess with anything less?

 

Theses engines can and will be damaged up to and including complete failure due to the use of porsche recommended mobile 0-40.
Nothing but 0-40 for me as well.

 

so mobil 1 0w40 is best to use??

 

Did you mean to say "due to NOT using the Porsche recommended Mobile 0-40" ?????

I think it really depends on the temp ranges in the climate where you drive.

 

Consult your owners manual. There are some other weights that are acceptable. I think 15w-50 is OK for summer use.

 

I live in hot north Texas and run 'Mobil 1 10w-40 High' Mileage year round and my 99 with 65k miles seems to love it.

 

See Porsche's website for a list of Porsche approved oils, choose one.

 

No but I was being a smart ****. Many oil wars. The answe is simply to use the recommended oil as per the manual.

 

Decide if you want better gas mileage, less protection and more oil burning and foaming or better protection for your engine. If you decide on the former, Mobil 0W40 (WATER) is the easy choice.

 

0w40 for me as well. They put it in there from the factory for a reason.

 

Yes they do, but the reason is not because it offers the best protection for your engine. It is the factory fill in order improve gas mileage and provide higher hp and because Exxon/Mobil compensates them to do so. Mobil should give them the oil for free since so many have to buy another quart everyday at retail, just to keep their engine filled.

I suppose the Porsche battery is also the best one for your car because of the factory install?

 

So...what oil do you use?
