93 SSEi with the mods listed in the sig......29mpg @ 70-75mph on long freeway trips.

320 miles per tank

Here are my last few mileage entries. Keep in mind that I like to feel moderate G'* as a I leave a stoplight (without loosing any rubber). Also, more important, is the winter months those #'* were recorded in. Snowy roads make a big difference in mileage (like the trip to St. Paul...had to drive 35 on the interstate going up!!!)

Interstate I find in general the faster I travel (closer to 70, 75) the better the mileage than at like 60, 65.



I've got a couple more entries to add for march/april, so maybe they'll be up towards the end of the week, and be reflected in my totals.

Ok now lets hear what brand 02 sensors everyone is using. Especially the high mileage ones.
My 90 has a Tomco (yes Tomco) 02 Gets 20 MPG city.
My 96 has a Bosch Manifold & Stock cat. 02 gets 15 - 17 MPG city.

I just installed a Bosch in my 93. 99 still has the factory in it.

I'm still getting 350 MPG out of the 99. And, 330 or so out of the 93.

where would be the best place to get an O2 sensor?

AutoZone, Advance, Murray'* or the like.

Dealer'* are too pricy, so use www.gmpartsdirect.com as an alternative.

i dont think we have any of those stores in T.O.

Crappy tire then for the o2. Delco works great for me.

40 MPG going 70-75 MPH in michigan, must be something in the air.

An intake kit, and premium fuel helps a lot. Just wish some places had 93 in town. All they got is 92. Anything above 80 MPH will EAT your gas. Every 10 MPH is just sucking away your gas. 100 MPH makes the needle move quick.

I get my best right around 70 MPH, running @ 2000RPM give or take a hundred

No.. don't go to crappy.. I just got a quote for just the parts for my 97 SSEI.. front O2 was about $173 and rear O2 was $78.. if you got time.. order it from gmpartsdirect.. it wil be cheaper.. haven't priced around other places yet..
