I have an 06 Vue with 2.2L. Last oil change at 5k and 9 months oil came out thick so I decided to 3k and check. Oil was black and with temps over 90 and 4 months I decided to change. Oil came out with clumps. Keep in mind I am regular with either Synthetic or Semi. Filter was nasty also. I decided to go back to Pennzoil only this time Dexos1. I even went to from the Purolator Classic to Fram Premium to see if dry noise on start up disappears. It only done this with Purolator Classic. I noticed when Goodyear changed oil they used Valvoline with Carquest oil filter and no noise on start up as I do most my own oil changes but got down with back so Goodyear did changes. 6 months oil changes and that is usually 3-4k oil changes. We will see if it like Dexos Pennzoil. Lots of short trips with a trip to doctors about 45 miles each way once a month. Have one in New Orleans tomorrow and so I checked it. Not that far but supposed to be 95 and with traffic just played it safe.
