my driving is all 70 and 75 mph on the same roads. I drive with cruise control and all my driving is getting up to highway and setting the cruise for 60 to 100 miles depending on where I go. It was definitely when I changed to Rotella. One of my questions is.... Rotella is a heck of a lot cheaper than the euro Penz., so are the oil changes going to go down???One other thing, I think the MPG hit comes more from the pcm flash for the transmission Shift points and higher rpm cruise requirements than it does from the oil viscosity. If not more than at least equal parts
Naaa
