Being the "3rd Car", my schedule the best to fix the exhaust, get it inspected, and re-registered to drive it legally. So, it sat -- sometimes moved in the driveway until repaired.

Many times, the batt was dead, so it needed to charge, even before the tags expired. As a result, it was a mixed-bag of inefficiency but results are better than expected!

Teggy is back on the road now, and is running quite well. The last 110 miles were without the SG (loaned-out for vehicle diagnosis), so that should return soon. I think the oil was changed during the hiatus.

TP: 60psi warm, excellent wear -- should rotate to maintain tread longevity.

This was an early fill to take advantage of a 40-cent/gallon discount from grocery store purchases, which expired at the end of this day.

Weather: Cold to more seasonably warm.

Driving: Airport run and local trip.

Mechanical: The PCV valve hose connection broke when changing the catch container, so both hose ends were taped until a replacement could be sourced.

The exhaust leak seems tolerable at this time.

Cold weather produces a noisy, metal-on-metal sound from a pulley (perhaps the alternator or main off the crank). It resolves after warm-up, has been around for a few years, and doesn't seem to be a problem (yet). Asymmetry from the absence of the PS belt might be the issue, or an over-tightened belt may be the culprit.

Teggy has sat in the garage for nearly 10-months, after license plate expiration and countless excuses for not getting it back on the road (new baby, back surgery, replacement car, etc.)

So, last month, a close (mandatory) inspection revealed excessively worn brake pads on the rear. I replaced those, got her re-inspected and back on the road today (with a fillup including Seafoam) and an inaugural run to the glass recyling bin.

The FE for this tank includes a LOT of cold starts and idling, just to keep it running well (and with shifting through the gears to pump ATF) -- otherwise, this tank includes mostly driving in the harsh Winter, in early 2010.

While sitting, it developed an oil leak at one of the front camshaft bearing caps -- it's not critical, but it burns where it drips.

Back on the road, it feels like a sportscar (compared to the Insight), so I'll have to resist the temptation to hit the gas for fun.

Teggy's assignment is 3rd car duty: trips to the airport / rental car lot for extended parking and recycling or cargo hauling. It lacks feedback, with the SG-II on the new car. The plan is to install a vac-gauge or use the Car-Chip for after-the-fact feedback.

This is a tough tank. The transition from main daily driver to backup hauler may have taken a toll on the FE. Running in bad weather and extending parking with cold starts were common.

This includes a short fill -- the gas pump had a fast flow and it clicked of. Another squeeze cut flow, so I figured it was full. Later, the gauge (if accurate) showed 7/8 full -- so we'll see.

3 out of 4 major commutes were in Thunderstorms with heavy rain and wind. Adding to that, several short trips and cooler ambient temps, and the result is lower than previous -- BUT, higher than average.

The PS delete is very tolerable and allows a much better feel for the how the vehicle is handling in addition to available traction and breakaway-skid threshold during cornering in rain.

Overall, highway speeds and acceleration rates are slower for competition purposes. There were fewer instances of EOC this tank.

3rd coolest July on record = less A/C. Combined trip tank: commute, errands, highway, airport. Completed bridge construction allows an efficient shortcut during rush-hours commute.

Vehicle idle RPM slightly lower than factory setting unless A/C or electrical load demands -- doesn't appear to be a problem.

Lots of rush hour commuting with this work schedule cycle. That + HOT = taking hit on FE.

With the thick traffic, it's tough to EOC, gently roll with the hills and just keep going. It seems I'm constantly slowing down and accelerating again.

This would be a good representation of a "City" tank...

Currently running 90/10 water/coolant and opened up airflow through the engine bay that fixed the higher temps problem.

Notes: Oil Change at 141K -- changed to "High Mileage" Castrol GTX 5W-30. Also adjusted the transmission-throttle linkage for smoother shifts (the CV joints are complaining).

Commentary: After the oil change and transmission adjustment, I noted a consistent 3 mpg drop in identical routes and conditions. Changing the oil occurred a few days after the adjustment. Theory: the gas pedal is much lighter on tip-in, where before it would pull the linkage immediately. Also, TC lockup was firmer. I'll have to monitor the situation to see if something else isn't going haywire.

I may reset the ECU due to the recent changes: new plug wires after catastrophic failure, transmission adjustment, warmer weather, etc.

This Tank: We had a sleet/snow storm that decreased mileage. Otherwise, business as usual.

Actually, take the average of this and the last tank due to the short fill, which = 32.55 MPG.

Other reasons for the decrease: More city driving, other family members have been driving the car, and the spark plug wires melted, arced and disintegrated into only 2 operational wires, resulting in 2-cylinder operation. After the repair, the wires have been popping off of the distro, resulting in Closed Loop and the requirement to pull over and plug them back in.

I may return the wires and trade for a different set or rig-up something.

Milestone: the vehicle just rolled over 140K miles.

Well, this is actually pretty good for Winter driving -- mostly city too. EOC is up and and so is the coolant temp. The full rad block is keeping the temps pretty high, but at least 190-200+ (and sometimes 240 or so).

FE, low-RPM power, and TC engagement is much improved with the higher temps -- but it's bound to get warmer. The higher temps likely compromise longevity, so, I'll make it a partial block until it's 50F+ consistently.

I decided to replace the cardboard radiator cover, despite the variable warmer temps. Keeping an eye on the coolant temps and adjusting the heater seemed to keep it from overheating.

The improved FE was from the warmer temps, faster TC lock-up and slower cruising speeds.

Better road conditions helped too...

Well, this is certainly a surprise. The first 100 miles were actually pretty good: in the low 40's mpg. Then the snow hit. Stop-and-go traffic barely broke 20 for the middle 2/3 of the tank. Then today, a 34 mpg commute with heavy traffic (stop-and-go in the morning, open in the afternoon) helped bring the tank back. Temps have been in the single-digits.

New mod: Aluminum Foil! A foil shield is now covering the exhaust manifold to trap heat for the intake. The grille block allows the engine to warm up quickly, but IATs are tough to get in the 100F+ range when on the highway. A partial undertray would be ideal, but time, effort, ya know...

Much colder -- really tried with the competition, but 20+ mph headwinds and falling temps hurt the final result. I've never P&G'd so much! But alas, Teggy is not a cold weather car, and I need more practice/instruction to get that elusive high-30's Winter tank.

The WAI needs tweaking -- after a cold soak, it takes a while to source heat, and a pulley is quite loud on startup (getting worse each Winter). Need to investigate.

Short fill before winter mods for baseline. 1/2 tank of 91 Octane to prevent detonation. Further fuel is planned for 89-octane on full fills. Price listed is for base/87-Octane for stats tracking.

Mods before fill:
* Covered the A/C radiator with shielding (wind block)
* Placed cardboard between A/C rad and Cooling Rad (heat retention, second wind barrier)
* Sealed inside leading hood edge with soft-sided velcro (on either side, bowed upwards and allowed airflow into the engine bay. The hood latch allows the rubber lip to seal in the center only.)

Notations on operation: coolant temps are higher and the fans operate often (45F today, tested in city and highway conditions. Colder temps are expected to reduce the need for fan use. This results in quicker warmups off-EBH and efficient IATs, sooner. Cabin heater use reduces the need for fan engagement.

-Traffic Jam started this tank
-Rain, Rain, Rain -- Wind, flooding, etc.
-Higher Speeds on Highway commute (short-term issue)
-Moving the car up in the Lineup -- more driving with passengers and for errands (Tessie requires premium fuel, and is costly despite the 30 mpg average)
-The car is just running right at this point

One mixed-up tank of driving highway, city, warm, cold, rain, sleet, snow.

Abnormally warm days (50's, 60's, even 70's) have heated IATs into the "inefficient temp range": 140F+. Not good. On the Sub-35F degree days, it works. Otherwise, it needs some control. But, soon Spring will be here and a regulated fresh air system is required or else it's ping-o-rama.

Much colder -- the segment that really brought it down was in the 3-5F range after a cold-soak start...windy and cold (52-mile jaunt). Lowest temps while parked for 6-days: -5F. Slowly cranked, but went. The rest of the tank, probably averaged closer to 32 (faster speeds than previous tank).

Post tune-up FE boost! Root repair: valve cover gasket and grommets. Additional tune-up items: plugs (gapped slightly wider than spec), wires, Seafoam to crankcase, oil/filter change. I never got around to changing the air filter -- scheduled "soon".

Odd thing: ambient temps were mostly in the single-digits and up to 25F for most of the tank. The last 5% of the tank was operated in the 40-60F range. FE was noted to improve throughout all temp ranges.

However: most operation was highway use -- sometimes with passengers.

Winter has set-in -- Driving in 0-20F weather, ice, snow, and slush. A rad-block has been added, which has helped keep temps up. The air intake has been re-directed to the engine bay for warmer inputs. Friction is still an issue at the wheels with the ambient temps. (mostly highway driving).
