My best milage was a trip to Chicago that I logged 21.8 mpg for the trip up......400 miles. I kept the speed at betwee 65 and 68 mph and it was all smooth highway miles - with the air conditioner off. It was a hot day too.<>I hope this has been posted under the proper headings.
The only concern I would have is For a clogged catalytic converter..
More from bobistheoilguy:
"Here is my thinking how people sometimes get better gas mileage by adding bogus things to vehicals that claim to increase fuel mileage. They instantly change their driving habits. They are driving more conservatively after adding such devices, and contribute the increase in mileage to the product. "
Your improved gas mileage most likely came from from other factors. Been there and done that.
As kids, when we got our hands on some dry ice, we'd put it in a can of acetone. The stuff got so cold, anything you dropped in it -- earthworms, for instance :-) -- instantly froze solid.
"ping" for the record
It's been a great car...it has over 250k miles on it. Original engine...2nd trannie.
Had "check engine" come on a couple times..both times it was "time" to replace fuel filter.
Not sure if I'm ready to put acetone in it though...I'll read up on it. I do use ProGard engine oil additive about every 4th oil change.
FRegards,
The check engine light on my 98 Lumina (256,000 miles) comes on because I have a bad connection on my gas cap or because I didn't turn the car off when I fueled up. There needs to be a certain pressure maintained to keep the light off, if I understand correctly. After the light comes on, The system runs checks on everything and it must check correctly a certain # of times before it goes back off. Unless you go to autozone and have the guy reset it. When it doesn't come on I get nervous, I'm so used to seeing it on.

I find that a small, neatly cut piece of black hockey tape makes the 'Check Engine' light go away quite nicely.
I dunno about you, but I'd go to Autozone, have the code pulled, and fix the problem reported by the code.
Anybody here know anything about a good fluid for my differential on my 88 Volvo with 200K miles? The thing is round-toothed and noisy, but I'm not going to make a repair that costs more than the car is worth. I have used Trans-X on transmissions, and find it to be miraculous (for a while, that is).
Is there something similar, to cheat on the differential (for a while, that is), make it work a little tighter? Appreciate.
By the way, that old saw (pun intended) about sawdust quieting and tightening a bad transmission is true--it works, an old mechanic told me. For just a little while, till the gears grind up the sawdust and make a wood-oil sludge. It works just long enough to unload the car....
Hey, any of you guys wanna buy an '88 Volvo? It's a real runner.....
Damn, I wanted to put that on another thread. Doh!
Bump for next week after my first test run.
I thought acetone had something to do with musical flatulence.
did you adopt that philosophy from bill n shrillary?
; )
I heard that if you put Preparation H on Al Franken he would disappear.
Here in Missouri, the outside temperature has hit 100 degrees many times this summer. I have carried my acetone in a quart steel can in my Explorer .... but this is a very stupid thing for me to do --- but, alas, my life is filled with stupid things that I have done. Luckily, there has been no consiquences to this bout of stupidity.
I imagine that on those 100+ degree days, the inside of the Explorer get way high....and the boiling point of acetone is 133 degrees. I wondered why my acetone can was empty one day!
Be aware of this point and don't carry your acetone in your super hot car.......
Powder..Patch..Ball FIRE!
Used this on my 89 Toyota. Didn't see much mileage increase but starting was much easier. Use it every fuel run now.
1977 Ford F250 460ci. Runs as if I put high octane in instead of regular. Very smooth at highway speeds and slightly lower rpm. Use every tank...
however, we got concerned and took one car in....apparently nothing wrong with the O2 sensor on that car at that time...
my car now, was a differant story......
we ended up breaking down just east of Big Timber Montana and had to be towed 75 miles and spent a lovely night on the outskirts of Billings.....several hundred dollars later, after timing belt was replace, plus water pump plus some spark plugs....we were off....
but not so fast....we made 3 other stops along the way for several hundred more miles .....
we eventually HAD to get the dang O2 sensor thingamajig replaced.....
when we got home, we rushed to get out other car's senor replaced as well as that timing belt, which, come to find out, needs to be replaced every 70,000 miles.....who knew.....
Moral of the story:....REPLACE THAT STINKING OXYGEN SENSOR BECAUSE SOMEHOW SOMEWAY, IT WILL CAUSE MORE TROUBLE IN THE LONG RUN......
I fixed the pinging noise coming from my engine by turning the radio up.
I have the codes for my volvo wagon, after taking it for service. I talked with the mechanic, and he told me to watch the instruments, not the IDIOT lights...
