So... before anyone rips me a new one I totally admit my results here are strictly anecdotal with no science involved.
I drive a 2005 Dodge Ram 5.7 Hemi in good shape with 208,000 miles on it. The engine burns no oil and has no unusual sounds coming out of it. I'm retired and drive the same routine week after week, local driving, some highway driving to big box stores like Menards and Home Depot and one or two trips a month to visit our daughter and her family 90 miles away. I want to get another year out of the truck before buying a new one.
For a couple of years I averaged 15.6 mpg, that number virtually never changed. A little over three months ago I added a can of regular size (not truck) Liqui Moly to the engine and reset the display. Within a week the mpg average sat at 16.4 and after three months it still sits at 16.4. I don't believe my driving habits have changed, I'm no more easy on the accelerator than before and I still cringe every time I look at the gas gauge.
Something is giving me better mileage, sure it could be something else but I'll probably add another can of Liqui Moly after the next oil change just in case it does make the old truck happier. Your results may vary.
