Oil for turbo and also service kit

[craiginuk]

Currently using Mobil 10W40 semi synthetic in my turbo. 125k miles, road use and one maybe 2 track days a year. Last time on track I noticed oil pressure dropping off a little when hot. Down to about 4 or so when flat out. Would it be better to move up to a 10W60. Something like this? http://www.halfords.com/motoring/en...oil/mobil-1-extended-life-motorsport-10w60-5l

I put Millers 10w 50 in mine.

Millers CFS 15W50 NT in mine. Works great. 10W40 should be fine in a NA engine but I would prefer a 10W50 or 10W60 in a turbo engine. My personal level of appreciation, though it's subjective and probably not relevant at all, is when pressure at idle with the engine fully hot does not show below 3 on the dash gauge. Of course that takes for granted that the gauge still shows what it should after 25+ years of operation, as I have seen some needing a recalibration after all those years.

My Turbo had Mobil Super 10w-40 in it when I bought the car and it seemed to burn a noticable amount. I have since switched to Total Quartz 10w-50 - now I have better oil pressure and have not had to top up yet.

Millers 10-60 in both my turbos and 968 also.

Im using Royal Purple 10w40 with no probs, now doing more track work and less road stuff so may step up to a 10w50 but my oil supplier is adamant that I don't need to go any thicker due to the properties of Royal Purple, in particular its film strength.

I like Millers - I'd have thought the Mobil 1 10w60 would be fine also. FWIW I use cheap Petronas 10w40 in the S2 (and Boxster) and it's just fine - wouldn't use it in a track turbo though.

I'm using Total Quartz Racing 10/50. Well respected brand and can be sourced at good prices on e-bay. Good for fast road and occasional track. I would recommend a 10/50 for any hard driven turbo or 10/60 for a really hard driven one though I found the 10/60 a little thick on start-up in the frozen winter confines of Scotland! Stuart

Thanks All, Actually Stuart, based on Hallsy's comment above I did a bit of a search on the quartz and found a post of yours possibly on Tipec mentioning you were happy with it too - so have ordered 10 litres of the 10W50. Anyone reccomend a service kit? plugs, air filter oil filter, fuel filter, sump washer? I see Frazer part do them but not too sure about oem air filter and fuel filter. Is OPC a good option? Cheers Craig

An oe filter will be ok if it's a Mahle one, as this is same as opc will supply, but lacking a porsche badge. It may have slight differences but more than likely it's the same. I have used Berlyn for service parts in the past, always had good prices.

For the parts either OPC, FrazerPart or Berlyn will be fine. In my Turbo I used Mobil 1 10W60. In the height of the summer with hard driving the pressure did not really drop off. It was what I was recommended to run the Turbo on. Personally I would go no lower than a 50 weight in a Turbo ; they do seem to produce some heat, more than the NAs it seems!
