This is due to bad piston rings and possibly damaged cylinder walls. The replacement engine is on its way and should be installed within the next couple of weeks.

But hey, 32 MPG from a bad engine that can no longer enter lean-burn mode is pretty good! I can't believe its still running with one of the cylinders that bad."

2012-04-06 424.1 9.431 $3.66 44.97 "It was about 70 degress all week long. My normal work commute all week. Was trying P&G but didnt realize my tires were only at 30 PSI the entire week. Today before fillup I aired them up to 45 PSI and then proceeded to drive about 30 miles before filling up at the station. I managed my best trip ever, at about 52 MPG. My usual trip average at that point of my commute is around 43. So lets see how the increased tire pressure helps us on the next tank. Hoping to cross 50 MPG."
2012-04-12 439.3 10.3 $3.59 42.65 "Was a lot cooler this week. Around 60-65 degrees. Instead of using P&G I have resorted to using lean burn and driving with load. On one of my drives to work I was able to get 52 MPG on that trip. Thanks to the colder weather I had a lot of trouble staying in lean burn. Basically at night it would not go into lean burn because of the cold weather. Thats why this tank is less than my previous tanks.

I need to get the grill block installed and make some sort of warm air intake in order to be successful using DWL in this car."
2012-04-18 412.1 8.898 $3.59 46.31 "This tank was very mixed. For most of it I did not have my MPGunio installed. It quit on me. I believe one of the power wires shorted with something on the board because it blew my radio fuse, and now the MPGuino will not pick up VSS data. It still turns on and reads Gallons Per Hour (which tells me that injector lead is working) but no MPG data which leads me to a VSS problem. My speedo in the car still works.

Anyway, since I had no MPGuino I drove with and without hypermiling. For the last 200 miles I did 45-55 engine on P&G. This worked extremely well and is why I was able to reach a personal best 46.3 MPG on this tank. If I were to do engine on P&G the entire tank I would probably have hit 50 MPG, my ulitimate goal.

I will try to do all engine on P&G on the next tank and see where I am at. Its very hard without instrumentation though!"

For this tank I had my ScanGauge II installed for the first time. Although it is not calibrated yet, I can still use engine load, TPS, and the feedback from the instant MPG to improve my driving. Sure enough I tried to drive with load. I would roll off speed up hills to maintain a lower load and then regain speed down the hill.

After all that effort it seemed to not help at all. I'm back to just driving 55-60 mph and not worrying about load or hypermiling of any sort. I plan on starting some mods soon, and I need to get my EGR fixed to get my lean-burn back!!"

It appears my assumption was right, the ScanGauge was simply calculating low MPG values with the EGR system working, compared with it not connected.

Initially when I first hooked it up I saw my instant MPG numbers plummet, which is why I wanted a full tank test to confirm. Even though this tank is lower than the last couple tanks, I blame the 100 miles of faster driving. I'll continue with the EGR connected to see if I can get back to normal."

This last week has been very hot and humid, unlike the record tank I set at 45 PSI. Hotter = more A/C = less MPG.

From now on I will probably just leave the fuel calibration alone. I would rather have it report worse than what I'm actually getting.
