I have a bit of Castrol Edge 10W60 left over from my M6. Is that suitable for a 996tt?
Not according to Porsche. It has approved no oil with a 10w-XX viscosity grade. There is on another forum a poster who has racked up over 400K miles on his 996 Turbo and mostly runs Mobil 0w-40 oil. He recently tore down the engine thinking it needed to be rebuilt -- even though it was not showing any signs of needing a rebuild -- only to find no measurable wear.If you want a slightly heavier oil there is a 5w-50 oil approved. Note that was not a typo for 15w-50. I just had Mobil 1 5w-50 used in my 03 Turbo's latest oil change and plan on sticking with this oil from now on. My Turbo just has 124K miles. Same goes for my 02 Boxster which has accumulated almost 285K miles running Mobil 1 0w-40 oil.
