WOW, that's cheap for RP. Red Line is over $9/quart now. Mobil 1 is getting close to $7/quart now.

Does anyone know why Porsche would remove it from the approved oil list?

I dont know, I do remember reading on renntech that 10w40 was for warmer climates and Southern California's weather fit right in the temp range recommended for 10w40 but they removed it and if you ask Porsche why, i think they are very blunt with there answer... Something along the lines of "Because it is no longer approved" which is not really the answer you want to hear.
OK called my Performance Service Center in Torrance Ca and Royal Purple 10W40 is $6.38, Price goes up with gas prices doesnt it???

Maybe it was due to valve tappet noise.

Could even be something as simple as better gas mileage. 1 or 2 extra MGP's. I don't think a 10W40 oil is considered an "Energy Conserving" viscosity. I know for sure an oil like 20W50 is NOT. I might be wrong about the 10W40.

0w-40 and 10w-40 are the same viscosity when warm.

But the noise happens when the oil is cold...at start-up.
