My second post today,anyway, my last oil change I thought I would try that new Mobil 1 0W-30.So far I am very impressed with this oil.It has been very cold here in eastern PA,and rite from the start when I poured the oil in (bottles were in my detached garage) I noticed how nicely it poured. I also noticed (from the old butt dyno) that it seems more responsive. Where I work,their are two steep hills I have to go up,(in a little valley) I always let the RX run for at least 3 or 4 minutes before I take off. Now,when I approach these hills,it goes rite up with a whole lot less effort,(and less peeved people behind me) where as before on the PP 5W-30 it just didnt pull as well on the cold motor.Also in these cold mornings,when I leave for work,it doesnt seem as stiff(I said stiff,AAHHAHAHHHHaaaa) as before.This just might be my new oil of choice for the RX,I`ll keep you all posted.

Nice! I noticed much of the same during the switch to GC 0W-30. I also noted a 1-1.5 MPG improvement.

Well blue,GC is still very high on my list.Except my RX uses a little oil on the GC.I even use the German Castrol in my lawn tractor,power washer,and push mower with excellent results.

Think it would make a diff on mpg in the mild Pacific NW? Also . . what is GC oil?
Not sure can get the "0" grade in this area of anything.

I assume he was speaking about Castrol Oil European blend full synthetic 0-30 wt. Here in California it is at Autozone and Pep Boys...

Yep German Castrol European formula made in Germany.Group IV of V synthetic. I forget which one it is. Very good oil indeed. It doesnt seem to break down easily,as I mentioned, I even use it in my air cooled engines.
