Motor Oil Question

I've had about 6 quarts of royal purple sitting in my trunk for the past 3 months. Stupid question of the day. Is it still good to use in the engine?

As long as it is 5w-30 you are good, it meets and beats the same standards as Mobil 1!

Been using 5w30 rp since I bought mine. Went from about 31-32 highway to 35-36. I was surprised.

Still getting the 35-36 mpg....of course that's keeping it at 65 though.

I've used RP in everything i own. E55, SS and the IRL. First day i brought home my E55 it went straight to the garage and RP was added in everything.

Used to be big into M1 but since they changed the formula it's not worth it.
