Well since I was given the green light to mix Mobil1 and Redline from Dave at Redline I've tried running a mixture of the oils for 5500 rpms. I just sent in my sample, hope to have results in a week or so. I ran 3.5 quarts Mobil1 and 1 Quart of Redline 10w-30, added about 1/4 quart in the 5500 kms. I figured the mix would bring the Moly count up to about 200 ppms as well as some of the other AW's. I'm currently running straight Mobil1 10w-30 and I will be running Redline straight after that for comparisons. This is on a Turbo 2.4 L Dodge with about 13,000 kms on the engine. Lookig forward to the results. Call me crazy but I think it will work decently.
