New mileage high!

[sc72]

Denso is the normal choice, #234-1010 has the end attached, at Advanced Auto it was $23.00 and change.

I used a Bosch universal.

Would have been better for MPG to use the Denso:

I just ordered a Denso sensor.
Ill change them out when it gets here.

Side question:
What maintenance items are there at 60,000 miles? My car is just over 60K.

[Oren09]

The O2 sensor isn't in yet.
Today I got an inspection. Passed Texas emissions. I was afraid my cat might be damaged from all the burned oil going through it.
Here are the inspection results if any of you exhaust knowledgeable people are interested:

High Speed (25MPH) (1963RPM)
----
Item / Standard / Reading
HC (PPM) / 184 / 165
CO (%) / 1.04 / 0.26
CO2 (%) / - / 14.4
O2 (%) / - / .2
NOx(ppm) / 1380 / 1063
Dilution (%) / >6 / 14.7

Low Speed (15MPH) (1755RPM)
---------
Item / Standard / Current
HC (PPM) / 191 / 174
CO (%) / 1.07 / .26
CO2 (%) / - / 14.4
O2 (%) / - / .1
NOx (PPM) / 1527 / 1301
Dilution (%) / >6 / 14.7

Everything passed.
If those number have an effect on gas mileage, maybe someone can make sense of them. Just thought I'd share. If it's too much, sorry, I'm excited because my car is fully legal now.

Haynes manual shows 60,000 maintenance has: check and reach front and rest bearings, replace fuel filter, replace timing belt, change manual transaxle lubricant

Thanks, jbuck.

Filled up today. 35.4MPG. Same as my past few tanks.
Almost all of the tank, 3/4 was after the tune up.

[Oren09]

36.0MPG last night.
I drove 55MPH for the first quarter of highway. 60-65MPH for at least 200 miles on that tank. Denso O2 sensor is installed.

I attached a picture of my gauges. Is my temperature a bit cold?
The ambient temp was in the 60's last night.
The engine was only barely getting over the cold line before, so I put in a thermostat from an old engine that had a small valve as well as the big valve (assuming its the proper original design). Fan switch has been replaced and the fan will turn on and off if the car idles for a few minutes.
Is the gauge inaccurate (~190* in the middle?), the engine running cold, or is this the normal operating temperature. My engine is completely stock.

Does ignition timing have an effect on any of this?

I'm sorry if I'm being annoying or if I've threadjacked. I'm just trying to figure out why my car is sticking to 35MPG. My old Festiva was NEVER less than 37MPG and averaged 40.

That's where mine reads at. But mine isn't 100% running correctly
