I been using PP 5w-30 in my DD. So this morning went to 3 AZ's to get a jug and all 3 didn't have the ol PP I been using. They did have some new jug stuff but all were 10-30. So on the 3rd stop I settled for the PYB 5-30, and figured it would be okay since I been doing 5k OCI's for a DI engine. I should have stashed up on the ol PP 5w-30 jugs - grrrrr live & learn. Other thing, one of the AZ I most frequent shrunk the size of shelf space for oil. Seems they now carry less oil.
