Hi All
I know this must be an old chestnut but newish to the site and Im interested on what you use.

Im looking at servicing my 1988 944 250bhp Turbo so can people advise on what they use or recommend, my car at the moment is totally standard, the spark leads are looking way past their best and perished in places.

Spark plugs?
Spark Plug leads? i was thinking of using Magnecor KV85's
Air Filter? was thinking of keeping the standard setup but using the K+N filter
Oil was thinking of Castrol Edge 0W-40 Fully Synthetic
Dizzy cap and Rotor arm?

Any tips or links to relevant pages would be great,
thanks.

Mark

Everyone has a different opinion but here is my take on it

Spark Plug leads? i was thinking of using Magnecor KV85's I would get a set of Beru leads (cheap they are not). I have never been that amazed with quality of Magnecor gear often finding genuine gear better in terms of longevity and fit. I know that on my S2 the quality of those leads (stock Beru items) far surpassed anything I have seen from Magnecor
Air Filter? was thinking of keeping the standard setup but using the K+N filter No problems with that. K&Ns however will need cleaning whenever a stock paper element will need changing, not quite the 'fit and forget' filter that they make it out to be.
Oil was thinking of Castrol Edge 0W-40 Fully Synthetic I would say that is a little on the thin side for a 944. I would probably go with a good 10W40 or preferably 10W60 (something like Valvoline VR1 or Mobil 1 Motorsport). Some do use a 10W50 with good results. For Mobil 1, if you are ever in the area I am happy to sort you out a good rate on it (I may have a cheap source...)
Dizzy cap and Rotor arm? Inspect them and change if there is corrosion/wear present with Bosch/Beru items.

Agreed go with Beru, check cap & arm as they never get changed!

Stick with standard personally, don't like the cotton type filters. Plenty on the web about issues.

Go with a good 10w/40 Synth ignore Mobil 1 marketing, plenty about for reasonable money, Halfords is pretty good.

EFA for IMHO! :wink:

I wouldnt use 0w-40 oil,too thin.
I dont really like uprated air filters,they just seem alot of agro for a possible few extra bhp

I've got both my 928 and my 944 running on Millers Trident 5w40.

http://www.millersoils.co.uk/automotive/tds-automotive.asp?prodsegmentID=918&sector=Car

Two reasons I picked this were. 5w40 was listed in my handbook and covers my climate temperature all year round. And also it has high ZDDP levels. I contacted their tech department and they replied stating it has over 1300ppm ZDDP.

It was fairly cheap too but I had to buy off eBay as I don't know a local stockist.

Im going to try Comma Eurolite 10w40 if i ever get my engine back.

It's good to see great minds think alike Jim

.

On a Turbo I would be tempted to use 10W50 or 60 simply due to how warm they get due to a variety of reasons (Turbo being one of them!). On a road driven S2 10W40 does the trick just fine

The Boxster is now running 5W/50 Comma Motorsport SL spec, lots of ZDDP & very reasonable money. Been surprised how much better it is running, not sure if that was the Porsche Passes & Palaces cleanout at 137 on the Autobahn or the new oil :mrgreen:

But someone else drove & said the same thing.

There you go. You now have a choice of:

0W40
5w40
10W40
5W/50
10W50
10W60

Hopefully that has cleared everything up for you

We'll for what it's worth I got quotes for my first service on my chipped 87 turbo from two reputed independents - GT One and RGA Porsche - and they both recommended 5w40 Mobil 1 v3000. RGA did say recently that if doing track work to go thicker.

Wow
thanks for all the replys and good advice, more to think about then.

10/40 or 10/50 end of. 0/whatever is way to thin, remember this engine design is well over 30 years old and no such thing existed in those days.
Go too thin and it will use oil and probably leak
