I just got this car and a couple tanks of gas shows im getting 21 mpg
from a 1991 cutlass calais. (2.5l 3speed auto,85k miles)
I just did a basic tune up ,ox
sensor,sparkplugs/wires,airfilter,oil/engine&trans.egr valve, 195f to
pass emissions and it passed.
I use about 30% flat highway- 30% in the city-40% on the highway going
up a mid sized mountain for 4 miles then down for 3. But when im going
down i almost never use the brake just coast the way down.
fueleconomy.gov reports 22mpg city 31 highway. Im always under 60mph,i
dont jump off the line, ect.
Does this sound right? I got this car hoping to get better mileage than
my old junker(78 lebaron) with a v8 (got 13-14mpg).
I dont know exactly the configuration of your engine, but I used to have
an 84 Fiero with the 2.5 Iron Joke engine, throttle body injector, and it
didnt really get any better than that.
Father in law has a 4 cylinder in his little GM picku (2-3 years old, I
and it doesnt get any better than that either.
Now, I had an 89 Buick Regal with the 2.8 litre TPI V6, and that sucker
got 33-35 mpg on the highway.
I had a 1985 Celebrity with the 2.6L "Iron Duke" (and the automatic
tranny with overdrive) and I loved it. The only problem was the V belts
slipping (need adjusting on a regular basis). I used to get in the mid
20's around town and in the low to mid 30's on the highway. The big
problem I found was that on these engies, they had a channel on the
intake manifold that was used for the EGR valve and it carboned up
regularly. You have to unbolt and lift the TBI unit to clean the carbon
out of the passageway. In 15 years and just under 200,000 miles, I
never had to do any major work on the engine and it still ran great when
I replaced it in 2001.

You're lucky. There was the big problem with cracking blocks in that
engine. (I think you mean 2.5, not 2.6)
I checked the situation on the Fiero with GM and they swore that my
block was not affected.. BS. It cracked, like the vast majority of them
did, above the lifter gallery into the water jacket. I went through
4-5 junk yard cores before I finally found the accidental good block
that was rebuildable.
GM, as usual, did nothing.
I get tired of them! <:)
Actually my wife always has a car a well. My wife's last car, an '87
Daytona was for 14 yrs.
My last two personal cars have been 10+ yrs,
with the current car going for 11 and was purchased 1 yr old.
If I could find what I want I'd trade in my very good Concord, because
my needs have changed. I also have functional design concerns with the
big 3 cars available today and may have to go back to an "import make"
for the first time since the 70s.
Since Concord is running so well I'll wait up to a few more years., but
I really need to serve that additional need in the near future. That
need is a modest sized (about 190" lgth) station wagon type vehicle.
Do you mean their engineering or appearances? I think most of the new
Toyotas, Hondas, Nissans, Mitsubishis are all real ugly. They aren't clean
designs. Whereas, check out the new Chevy Malibu, Pontiac G6, Dodge
Stratus, etc.. Much better in my opinion, but you know what they say about
opinions. I actually also like the Korean designs like the Kia Optima,
Hyundai Sonata, Santa Fe, etc.. cleaner designs than the current crop of
I drove a 1988 Chevy Celebrity sedan for 5 years in the late 90s for 5 years
with the same engine and transmission configuration.. It was easily getting
35 mpg on the highway..I loved the fuel economy but acceleration was a joke!
too heavy car and only 98 or 100 hp engine! It killed me on the ramps..Also,
lots of carbon built up occurred..
I've got a 1988 Pontiac 6000 with the same config. The 2.5 stalls a lot.
Watch the timing gears on them. Mine easily gets the 30's on the highway,
but in the city, the fuel economy isn't any better than an SUV in the city.
Oh yes, and I have to almost floor it to make it up an incline going 65mph
without losing speed. The Celebrity we had before this car stalled also.
We got rid of it when the head cracked. I don't know how many miles it had
on it. Both cars do/did well in the winter weather provided it would start.
Both cars are still running today, but the 6000 is in trouble with a tranny
leak @ 124k. We'll have to see what the outcome is. The Celeb I assume was
