I got the oil change fever last month and went with German Castrol(PureOne filter) in my Dakota. At first everything was as usual, but after a trip to Vegas(Cup/Busch race ) I looked at my dipstick and the oil was a "redish"/"teriyaki-ish" color???? I have tried many different oils: Mobil 0w-20,0w-30,10w-30; Royal Purple 5w-30, 10w-30; Chevron 10w-30(Supreme&High Mileage), Delo 400 15w-40. Some I liked more than others for any number of reasons(most un-scientific). And I have NEVER seen an oil EVER look like this, much less in only 1,215 miles. I did use Redline fuel cleaner in my gas on the way to Vegas. However I have used RL before many times and have never had this "problem". I am not sure that this was indeed a "problem", but it was most discouraging to see the oil that color. Yes, before you ask, my motor is in perfect working order with 61,000 miles on it. I went back to Chevron Supreme 10w-30(PureOne filter) and I have 1,070 miles on the oil and it looks just like it did when I poured it in. I am going to stay with Chevron Supreme 10w-30 changed every 3,500 miles. Any thoughts on why GC turned "red"????? Darryl Loose in, tight off? Drive it in deeper.
