Thanks for the question and using SPEEDiagnostix. Because the change in Oxidation performance with the new formula of Pennzoil Ultra Platinum was so slight, I would not recommend changing away from it. As you get more samples on that new formula, you will...
I'm gonna reach out to them and see what they say. I know it does not matter anymore since you switched to BD but I am a loyal customer of theirs and want to see what's going on.
Ok since I started this "controversial" thread I want to be clear with what I was asking. I just wanted to know what people were doing since PUP changed it's formula. Pretty simple. I chose that ould due to it's thermal capacity as it relates to the turbo bearings and film strength. Is it the...
