Checking around google others experience the mileage issues with MaxLife as well, but its a very good oil.
I cannot tell any MPG difference whatsoever after starting to use MaxLife. I am not disputing there may be some tiny bit for others, but I can say for me, zero difference.
There is a measurable difference. If there wasn't, it would have achieved an energy conserving rating. It is not labeled as such because it was proven in lab testing to not produce as good of mileage as the base oil it needed to surpass.
