Hello everyone, I took my 2006 Kia Sedona into the dealer yesterday for an oil and filter change (and to take an oil sample for analysis). I took in my own Pennzoil Plat. 5W-30. They gave me a really hard time - saying that it was the wrong oil and I should have brought in 5W-20. I told them to use it (the owner's manual specifies 5W-20 or 5W-30). When I got home, I checked the oil level with the dip stick and noticed that it wasn't that golden yellowish color, but it had a slight brown tinge to it (as if it had been in for 500-600 miles). Does this sound normal to you? I had about 6190 miles on the oil (the vehicle has 38000 miles on it). My previous Blackstone Labs Oil Analyses were good (apart from decreasing amounts of higher than usual silicon from a timing chain tensioner repair). Many Thanks!
