If it were someone other than Jeff I'd say they'd been snow-jobbed by the recent marketing campaigns of the oil manufacturers recommending Special Oil for SUV's, Special Oil for Cars, Special Oil for Black Cars with Red Stripes, Special Oil for Cars with More Than 4 Racing Stickers, etc. :nuts: And of course these Special oils do happen to cost more. Hmmmm...... What might that be??? Marketing, perhaps....???? LOL AS IF the appropriate oil is determined by mileage instead of actual engine clearances -- Do ALL engines suddenly get loose at 75K miles??? And suddenly they all need 15w50??? Uh.... No. I'm calling Marketing Bullshit.
However, since it's Jeff, I'd be interested to read his reply, because he probably has a legitimate real world reason to recommend what he does in this case.
I think I recall seeing reports from guys here who do regular oil analysis (maybe it was Chip aka Lagtime?) that they've seen RP oils result in less metallic components in the oil...which indicates that the engine wear surfaces from which those metals get into the oil are wearing less.
So wanted some input.

Car is stock with 215k miles and is a 94 Turbo model. I have the random manu light with automatic shift lockout. This is coupled with another strange phenomenon in which both green lights on the dash under the tachometer for 2 gear and L gear will illuminate simultaneously if the shifter is in...
I have no power to fuel pump or diagnostic. I know I get power from efi main relay. Bench tested relay and I good. Checked resistance for ground and that is good. But voltage coming from the ECU is only putting out about 7 volts to the relay which isn’t enough to kick over the relay coil...
