Fully synthetic to Porsche A40 standards will be better..............
Plenty about other than Mobil. Fuchs Titan, Shell, Castrols,etc. 0-40 will get it round the engine better until it warms up. 10-40 is very 'thick' when 'cold' ie before the engine is up to design temp.
I see the Hartech rec. which is interesting. 10-40 and 0-40 are the same at operating temperature and will flow the same volume of oil but the former will flow lower volumes at startup, which is when most wear occurs.

Be interesting to see Hartech's reasoning behind this. But they know their Porsche engines and I'm sure there is a good reason for their choice. The use of Magnatec 10w40 is even a stated condition in their engine rebuild warranty.Plenty about other than Mobil.

We actually use a variety of different oils including 5w40, 10w40, 10w50 Nano & 20w50 - some are Porsche approved and some aren't. As a car ages and is subject to different uses, driving styles & wear rates different oils should be used. Consequently we don't have a blanket set of recommendations but weigh up each case individually.

but can anyone tell me ..can i put castrol GTX 10w-40 part synthetic oil in the engine ? with out doing ireparable damage
i will not be racing the car , just a sunday driver, about 3 or four thousand a year
Why would you want to risk any damage to your expensive, precision-engineered (no I'm not being sarcastic) Porsche engine by putting in oil that was designed for a Mk-II Escort? Very, very false economy.but can anyone tell me ..can i put castrol GTX 10w-40 part synthetic oil in the engine ? with out doing ireparable damage

ok.......
its looking like Castrol Magnatec...10w-40
unless someone has a better idea !!!!
the manual isnt specific
neither is the official porsche recomended list !!!!!
so us newbies have to ask about
What is making you want to use something different than the oil the engine was designed to work with - i.e. Mobil-1 0W-40? The Mobil does the job perfectly well.its looking like Castrol Magnatec...10w-40

Jimmy - happy to talk over the phone about this if you like. Rather not chat on the forum as oil seems to bring very emotive views and difficult to weigh up who actually understands the subject properly or otherwise. Need more info such as mileage, frequency of past oil changes, driving style, general engine condition, your buget and future plans for the car, etc I`m around tomorrow.

What evidence have you that the engine was designed to work with Mobil? Porsche approve many makes and grades of oil for use in their engines.Just because Mobil have the best marketing machine doesn't make it the best oil.
If you scan the www you will find more than 1 test where Mobil doesn't come out too well for film strength etc. it's OK but probably not the best by a long chalk.

You're opening an old can of worms here, but if its good enough for Maclaren.......... Just because Mobil have the best marketing machine doesn't make it the best oil.

You need to do more research into oils and viscosity as it is not anywhere near as simple as you suggest. Even LN Engineering suggest using a higher viscosity motor oil to guard against IMS failure see http://www.lnengineering.com/ims.htmlMost engine rebuilders suggest 0W 40 is a problem and suggest 5w or 10W 40. You need to research the 0W bit as it does not work the way you suggest.

My advice is use an approved oil. There are plenty to choose from if you do not want to use Mobil 1 0w-40.
The 10w-40 oil you are considering should not even be considered. 1) The oil is not on the list of approved oils. No 10w-XX or 15w-XX oil is on the list. One has to wonder why? Is Porsche so inept it overlooked one or more 10w-40 oils? Maybe the reason is none of these oils is up to the task of properly lubing a Porsche engine given the variety of types of driving styles, climates, etc?
Next, the 10w-40 oil is not fully synthetic. Porsche approves only synthetic oils for its cars.
Even the indy engine builders can't agree on which oil is the best. Heck one here in the USA even has the audacity to recommend Mobil 1 0w-40 oil! Geesh, he must not have got the memo.
My only advice beyond sticking with an approved oil would be to at least change it once a year. Those 'low' miles and possibly short trips means the oil will become more contaminated over that year with water and unburned gas and this can render an otherwise good oil less than good.
Sincerely,
Rockster.
the Porsche Approved List, ( over 75 different branded oils !!! ) does not list any 10w-40 oil !!! but.....
in my boxster hand book, page 145, under the sub-heading...
Engine oils approved by Porsche.
OILS OF VISCOSITY.0W-40, 5W-40, 10W-40..AND HIGHER !!!
IF THEY COMPLY WITH THE ACEA A3 SPECIFICATION !!!!
SO I WOULD IMAGINE THIS IS WHERE THE CONFUSION ARRISES.
as the gentleman from HARTEC says, its alll about how and where you drive,
you would have thought a manufacturer as big and respected as Porsche, would give its customers precise and accurate info on some thing as important as oil !!!
Although it does say .." Hydrocracked , or Synthetic Oils only !!!!! "
