Oil changes

[Shellman]

Is there any reason why I shouldn't use Castrol synthetic oil in my 03 Boxster, instead of the Mobil?

 

[Mark_Bennett]

No reason at all.

The manual states which oil standards are acceptable.
The Castrol Synthetic meets or exceeds those.

Why? Have you got a super-cheap supply?[]

 

[thboxster]

Yes, if you've found a good deal, don't be affraid to share this info with us, we won't tell anyone.

 

[Rodney Naghar]

My OPC actually used Esso oil for my service.
Cheapskates.

whilst there doesn't look like there's a cheap supply of Castrol there obviously is with Esso[]

Todays silly question

Do you guys do this or get it changed earlier ? - I find such an interval before the first oil change a little worrying

Todays silly reply []

Why?

I find the way some OPC test pilots race a fairly cold engine far more worrying []

Ian, my 987 has done 9,700 miles and will be 2 years old in Aug this year necessitating the calendar interval service. I'm an Aerospace Engineer by profession and have alot of confidence in todays synthetic olis, particularly the consistency of the oils properties over time. This coupled with the tolerances and machine finish on todays engines means you shouldn't be worried. Service intervals are carefully designed and are never placed at the limits of the cars maintainability requirements by Design Engineers. Just make sure the oil is replaced by a high quality oil recommended by Porsche Engineers.

Changed mine at 10k miles - don;t care how good the oil is, the cost of a DIY oil change (<£100) is peace of mind for me.

 

[jpbecker]

Well you certainly won't do the car any harm!

Have been looking at getting my oil changed too; car is just 1 year old and done 7K miles. The OPC wanted £220 just for an oil change; is it an easy DIY job? Does it affect the warrenty?

It's a very easy job. I think there are details on the rennlist forum (I'm fairly sure that Maurice Piper published stuff for a 993 within the 993 register report a while back - the Boxster may well be easier than a 993). You'll need a wrench to get the filter off - you could go to Halfords to buy something that'll do (an official filter wrench is 76mm with 14 flats - I got mine from snap-on (FW7614), about £15 delivered). The rest is easy. Make sure you've bought the correct washer(s) from Porsche (I'm not sure whether a Boxster has two, one for the block and one for an oil tank or just one, and whether one is aluminium and the other copper - Porsche call them 'sealing rings' rather than washers). You'd be wise to find out the torque settings for the block/tank (a GT3 block needs 70NM for the crankcase and 60NM for the tank) and filter (the filter probably has 25NM written on it. The element itself is made of paper) - Porsche will tell you these. The Club has a set of technical manuals, so if necessary........

Insisted on the oil & filter being changed when my wife bought her ex-dem 987 (at 3k miles). Changed it again myself at 10k miles.

BTW Porsche will not change the oil filter until the second service or 40k miles. Now that just strikes me as ridiculous.
