Guys... it is not just about filter and air filter... we know from our past experience that changing these two accounts for some change... but not in such a dramatic change.
On my car, everything was running for a year before I started trying out MMO... On this MMO full tank plus Startron at half tank... I have driven 446 miles and I still have over 1/4 tank left... more like 5/16 tank left. My tank is 23 gallons total and 3 gallons reserve. My driving is strictly local driving. My town is pretty hilly.
As I drive, I am not trying to minipulate... by accelerating as slow as possible or anything like that. I do however coast as much as I can... but not rediculously either. For example, I see red light ahead and I am driving
45 MPH... I would coast for 1/2 mile into the intersection... there is no point to keep foot on gas until light and then slam on brake.
My average MPG around town for 2 years is 25 or 26 MPG... below my 27/35 EPA rating. When I first got it, I was getting 30MPG average but didn't last for some reason... I think Algae is a huge reason on my car even though the 2 fuel filters shows zero black algae or black anything at all.
Now I am getting over 32MPG around town when I usually get 25 or 26. I get
29 MPG when I spend $9 on diesel fuel injection cleaner two separate time but then drops back to 25 when tank is finished.
