I was wondering if anyone has tried the Rotella for gas engines yet? I am almost due for an oil change and have been using Mobil 1 synthetic since I bought my Tahoe 3 years ago. One time I changed to the high mileage and it seemed my L9H ate that stuff. It was the only time I ever had to add oil between oil changes, so I only used that shit once. However, I have been seeing Mobil 1 isn't what it used to be and have been considering switching to Rotella for gas engines. Should I try it, or keep using Mobil 1? I have around 165k on my L9H and want it to last until I buy a house. Mechanically, there is nothing wrong or even remotely wrong with my engine, just has the 'normal' early morning piston slap. I think this engine may last well beyond 200k
