Yeah, I was concerned about that "3500" bit as well, but we double checked the various info the dealer had, and it's still the right stuff - and still carries the DC/NV MS-9224 spec...
Mine was only $10 per qt at the local DC dealership, I have no idea WHY the price varies so much from one dealer to anothr, but I haven't been able to locate any of the above Pennzoil stuff locally at Sams, Walmart, Kragen or Pep Boys... If I ever DO locate some, I'll buy a CASE of it to carry me for a few years...
