Hi mate.
I've got a Hartech rebuilt cayman s, which is currently running millers xfs. As I understand it though, this is just for the 'running in' period (2000 miles).
Not sure millers is a standard oil that they usually recommend/use.
Why did it need a rebuild m8, what happened, how much did it cost please?I've got a Hartech rebuilt cayman s, which is currently running millers xfs. As I understand it though, this is just for the 'running in' period (2000 miles).

This is the oil Hartech seem to use and recommend:-

Be good if Baz or anyone in know how can comment on the positives / negatives of using this over the mobil one 0W-40 Porsche recommend?

Sure there are disadvantages.
Ignoring that it is the wrong oil for the engine (no Porsche approved oil is a 10w-xx oil) the higher W number means the oil flows less readily during a cold start. The risk? Bore scoring! If the bearings don't gall up first. Or the zero-lash lifters suffer from lack of oil flow when the engine fires up. Or the VarioCam Plus hardware suffers from improper lubrication or the viscosity differences result in added wear and tear to the VarioCam hardware. Or this oil's splash/sling characteristics are different from that of approved oils and the splash lubed camshaft lobes and lifter bucket faces receive insufficient oil at start up or at other times.
The oil is very likely to result in a drop (it may be too small to notice) in fuel economy. A heaver oil results in more friction and this takes power to overcome.
Also, more friction means more heat. There is the possibility the thicker/heavier oil could suffer from high temp/high pressure break down as it overheats in the tiny clearances that are the rod/main bearings.
Based on that amazed Hartech recommend this oil to prevent bore scoring???Ignoring that it is the wrong oil for the engine (no Porsche approved oil is a 10w-xx oil) the higher W number means the oil flows less readily during a cold start.

Doh! If only Baz had known! 40 years buidling engines and an international reputation as the foremost authority on M96/7 cars and a couple of years working with Millers to determine what works best and he gets it all wrong. I know which oil my 996 will be imbibing, and it's not Mobil 1.
Are you using this Millers oil m8 I've linked too?hartech said:
Gibbo - I am not at work today so will reply later in the week with the right specification we recommend - but our recommendations refer to typical road use and for track use it is important to fit a deeper sump and/or acusump if you corner aggressively - or you may lose oil pressure in long corners.
Do you have the X51 deeper sump and what oil do you presently use.

Mine is a 997.1 C2S so there was no deeper sump option, it was 996 option only. Currently use Mobil One 0W-40 and change it every 5000 miles or after every track day. I do 5-6 track days per year on road tyres, I don't use slicks! To try and prevent loss of oil pressure I always over-fill the oil by 300-400ml before a track day so all the bars are lit on the in-dash oil readout and ensure it never drops below max during the day.
I want to try the Millers NT stuff, just need to know which grade 5W-40, 10W-50 or 10W-60?

Some claims for nano oil:
- less friction
- less wear, therefore longer component life
- more power (a tiny % though)
- less heat because of less friction
- better shock resistance
the benefits only become fully active after 1 or 2 hours of running as a slip layer or 'tribofilm' needs to be developed before the benefits materialise.
F1 use this technology and I think I am right in saying it was one of the factors that gave Brawn the edge in their winning year.
Give Millers a ring and they will advise which grade to run ..... I am guessing that they will suggest one grade thicker than your current oil because it is so slippery !! NB Should give good benefits in a gearbox as well because of all losses due to friction.
Shall see what Baz recommends, but based on that seems 10W-50 would be best shout, shall see if Baz chimes in, if not shall give them a call. - less friction
