||1.939||hours of cruising over the speed limit along with a couple of traffic jams and some city driving. Warm temps helped!
Just noticed in just the last week the car logged about 1k miles! Wow! Too bad for the car this was on the last leg of its 10k mile synthetic oil.
After this fillup just added royal purple oil (on sale! 5w-30), filter, seafoam'd the motor (inside and out), and replaced the leaky VC gasket/gromets/tube seals.||45.40|

||1.899||Not eco driving||39.07|
||1.939||been beating on vx too much lately, scared to see how this one turns out||35.31|
||1.839||Bit warmer, summer 13in tires, no flats, 34/36psi, added mud flaps, lowered front of car||47.16|
||1.939||Plenty of city driving||39.91|
||1.799||Cold driving. Partial flat for most of the driving.... Fourth in 3 months.||36.94|
||1.799||Cold, car was having some issues.||41.07|
||1.719||All highway. New plugs, radiator, OEM fan installed, plug wires. All 4 snow tires on.||42.30|
||1.699||Free wawa gas||42.78|
||1.699||Very cold temps - free wawa gas||39.30|
||1.659||Very cold - Weighed down car||36.54|
||1.839||Rear tires had very little air in them (under 20 psi). Front were also kinda low. Probably why the MPG has been dropping lately.
Just added the air to 36 psi front/rear (11/17/08).
Much colder temps.
||2.799||80% highway driving around 75 mph - car loaded
Getting colder! Don't think there is winter-blend yet though.
Added OEM grill block, OEM VX lip, and OEM VX rear diffuser. Still have the rear mudflaps on the car though... For the next long trip I take I'll take them off. Most of my driving is on back roads, one of which is a dirt road, so the flaps help a lot to keep the rear window from getting dirty. I also made the intake into a warm-air only setup using the OEM setup.
Just changed oil with synthetic 5w30. Also seafoamed the the intake, fuel, and the oil at the time of the oil change. Car still needs new spark plugs and plug wires (all the connections need to be recrimped and the wires will fall apart if I take them off) which haven't been replaced for over a year (copper NGK v-powers which wear quickly but work amazing).||46.61|
||3.529||Rural driving, plenty of stops.
||3.69||80% rural - driving to work and going over the speed limit to get there early
20% highway - driving on the speed limit mostly||43.27|
||3.479||Short trips to work (10 minute drives) on back roads, lots of stops. Also a lot of stop and go city traffic. It's now due for its 8k mi oil change and it's ready for plugs and wires. I'm going to push those off till about two weeks from now...:O||41.11|
||3.739||Over-loaded car due to moving, very hot with windows open||46.88|
||3.899||HOT summer driving, windows open||46.57|

||3.759||Small road-trip from OC MD to DC but a decent bit of stop-and-go||47.98|
||3.679||All stop and go.||39.18|
||3.519||Mostly highway with a car loaded with a few hundred pounds of stuff.||45.57|
||3.279||A little warmer weather!||43.52|
||3.239||It was kinda warm for some of this tank (in the 50s), so it helped it a lot. Lately the pumps I use have been not giving me receipts, so that's why I haven't updated this gaslog lately.||50.07|
||3.059||Winter driving, no highway
First tank w/synthetic. New plugs. New fuel filter/oil filter.||41.96|
||2.999||Road trip w/ very different pumps. I think this was one of those unreliable readings.||39.38|
||3.099||Winter daily driving||40.74|
||3.119||More winter daily driving||49.71|
||3.139||Winter daily driving||47.64|
||2.999||This was a lot of cold driving, snow/ice driving, and being stuck in city traffic for hours...||43.71|
||3.069||Last pump I had one that kept shutting off before being full, and this time the pump shut off when the gas tank almost overflowed, so I think this fill-up is off by about a half gallon.
I did about an hours of very slow, snow driving, so I think that caused the MPG to be lower also.
Temps have been cold for this tank.||44.22|
||3.069||Did about 100 miles of highway driving. Last tank I used a strange pump, so I think that's why this isn't my best MPG recorded though I think it should be with this upward trend my car has been getting. I ordered some 185/80/13s for snow tires, and since they are skinnier and a little taller than the current 175/70/13s, they should yield better MPG for the next tank, which they will be installed for the majority of.
I hit a few traffic jams with this tank, since it was the Thanksgiving holiday (biggest travel holiday of the year), so I think that contributed to this tank not doing as well as it should have.||44.96|
||3.059||This is the 2nd tank with the shift-light, so I'm still getting used to it, but it has helped me shift much better than I was before. I finally converted the intake to warm-air only, so this has already made the car warm-up much faster than it was before. Temperatures have still been cold here, and my driving on this tank was limited to 100% rural roads. No highway driving at all. I was hit by a deer while driving on this tank, so my car's aero will now be somewhat diminished... :(
I did have a pump issue when filling up on this tank, but I did stop when it almost over-flowed, so I THINK it is accurate. If not, I'll add this disclaimer since this is my best tank lately.||46.74|
||3.059||Just got the shift light working for this tank. Also installed the OEM intake for most of the tank, but didn't install the part that makes it so it only sucks warm air...so basically, even though it was about 35 degrees out the entire tank, I still had it sucking cold air...stupid me. Also did a Seafoam treatment which entailed having the car idling at 2000RPM for about 10 minutes while slowly pouring it in, and then after it sat for 5 minutes, I took the car to red line multiple times, to clean-out the carbon in the motor. Afterward it idles lower, and drives smoother, but I'm sure that killed my MPG for this tank. Temperatures were also very low for this tank, the high the entire tank was probably about 45 degrees. This tank also had zero highway driving. Did a few roadtrips, but they were all on rural roads with lots of stops...||42.61|
||3.06||Doing a lot of neutral coasting, but I think my shifting is too low in the RPM range. Just fixed my shift-light at the end of the tank, so hopefully it will help. Tires around 40 psi. Car is running perfect. But it has been getting much colder lately, and I've heard the "winter" blend gas is now in the pumps, with added ethanol. :(||45.62|
||2.73||I actually drove my friend to MD to pick up his VX on this trip, and a lot of the roads had a 65 mph speed limit, which is the speed I drove. Generally around my area highways are 55 mph, so I think that is why my mileage went down due to this trip.
I also added a plastic, and larger grill block.||45.27|
||2.859||A little less mpg than the last tank. I did a lot of highway traveling, and this was the first where I was trying some pulse and glide methods. I should get better at it I think. This is also the first with the grill-block.||45.99|
||2.73||Well my car sat for 3 months without being driven between the first and second half of this tank of gas...
For the first half I beat on the car pretty bad, since it was going to be the last time I could drive it for a long time. I let the car idle for about an hour after adding the fuel stabilizer to the fuel, and then I stored it away all summer.
I got back, and then I realized I want to get the best MPG possible since right now I am out of a job, and b/c of that, I really want to save as much money as possible by changing my driving habits. Before this tank, my average was probably about 40mpg, though I often didn't check the mileage, or really care at all.
For the second half of this tank of gas I began to accelerate very slowly, coast in neutral as much as possible, not go over 5mpg over the speed limit unless going down a hill, and keep the RPMs as low as possible all the time. (though I did do one burnout just since I felt like it....)
For now on, I plan on getting as good as mpg as possible by changing my driving habits as much as possible.||48.00|
