My Attempt to reach 40mpg.

Try to find a dial gauge. I dont care for digital ones.

Took back stick gauge and spent 2 dollars more for a dial guage. Tires are now at 40 psi. It's definitely much sharper turning fast.

Bike pumps work great for inflating tires too they need something like 60 psig. Just need to pump more times for a car than a bike (more volume for the car but less pressure).

32.41 Up .5 mpg

Only real change was 40 psi in tires.

I had a lot of short trips though, which probably killed my mpg. I was really aiming for 33 mpg. Hopefully this warm weather will help out a bit.

I can hardly believe it myself, but I just hit 35.74 mpg.

Something like 80-90 percent highway driving. Of which I, but maybe one small trip, never went over 55 mph.

I probably would've had an even better tank had my radiator not had a small leak that required using Bars Leak and leaving my car idle for a bit. My dad also found it necessary to rev the engine up while it was idling too. It was probably a 10 minute ordeal.

I'm not sure how easy this tank will be to replicate and improve on. Maybe once I don't have 6 and 3 mile trips everyday for school.

That's great. How much coasting in neutral did you do? If none, perhaps that's all you need to hit 40 mpg!

The first 100 miles had maybe 3-5 miles of neutral coasting. maybe. I really didn't do it all that much.

I feel like I can really hit 40 mpg now.

I haven't got a single clue how I just hit 38.94.

Different gas station maybe? But even the needle was in a relative location to amount of fuel used based on previous tanks.

I didn't even keep it under 55 but for probably 60 miles. Went 60 for atleast 40-50 miles. Would having drove for 2 1/2 hours straight affect that?

Even got stuck in mud but that was only 2 minutes.

Any ideas how this happened?

Looks like you just finished your first tank with summer grade gasoline in it. My last 4 tanks with similar driving styles going mostly to and from work were aprox. 35, 35, 37, 37.

Some updates.

I've been trying 60 mph. Last tank, although a bit short, showed no real difference even had ac on during acceleration as some people here seem to think it has less drain then.

Trying again this tank, but with more neutral shifting.

I've been considering putting in a gallon or two of e85 once the full tank has room for it. Would it mix in enough to not matter as far as being safe for my engine? Only reason I want to do this is the fact that e85 is 2.99 while reg gas is between 3.95 and 4.10. So having two gallons mixed in with the tank would save two dollars or so, which would take me back to around 20 dollar average for 200 miles. Just an idea.

I think I'm going to seal off grill block a bit better soon too. Just need to get some clear silicone.

Also, oil is 5w20. Ford dealership seems to be using that now.

I'm fairly happy with what I've been getting. May average was 35.7 mpg. 10 mpg over epa combined.
