Originally Posted By: Benito HTHS viscosity is more important than grade. The Euro oils must all have a minimum HTHSv of 3.5 regardless of if they are xw30 or xw40. However, Porsche and AMG require oils that are xw40 and not xw30. So if HTHSv is the most important thing, any idea on their...

Shannow, Nice description.

Thanks Doug!

My takeaway was if that's what's happening with the camshaft, can you imagine the crankcase running at twice the speed with bigger "blades" (ie big ends and counterweighted crank throws) chopping at the streams of oil coming from the mains and the big ends and other locations such the return...

Originally Posted By: MolaKule The problem with "overfilling" is the potential for air entrainment which reduces the lubricating ability of the fluid. The manf. wants to try and avoid as much "whipping" of the oil and air entrainment as possible. One of the areas of whipping they try to...

Well there you go! Thanks Supercity. I guess the question of feeling comfortable using a C3 formulation that also has 229.51 and A40 accreditation probably comes down to two things: Are you a high or a mid SAPS person and Do you have a DPF equipped diesel daily driver along with your classic...

Hi SDS, Could I clarify a few things please? I’ll just add notes to your original paragraphs to avoid any further confusion. Peter: I think you are creating a straw man. I don't think I have said there is only one viscosity or brand that is best, nor do I think LN/Charles Navarro is saying...

Let's ask a hypothetical question then! Let's say Doug is gifted a 1993 911 just like that owned by the OP. Let's also say that the Australian government quarantines any further imports of Mobil 1, Delvac, Castrol, Fuchs or Shell oils so he can't rely on personal experience any more. Let's also...
