Thanks for the information. Okay, I'm kind of shocked at this, but I ended up trying what this mechanic had recommended trying ( without any guarantees of it working, but what did I have to lose? ): In a full tank of gas, add 1 QUART of Denatured Alcohol, drive the tank away until you finish it, see what happens. At the end of the tank, the light was still on, BUT about a third a way into the next tank, "poof" the light has gone out! If it comes back on, I will try the unplugging the battery cable thing. At this point, I don't know WHAT to think. Usually I fill up at the 76 station, or Chevron - I have a gas card and this helps track fuel cost, but these past two tanks I have gotten gas at the local Valero ( Exxon in other words ). I consider it the "cheapy" gas station. I'm hypothesizing the gas at 76 is too "rich' and the Aerio too sensitive, especially with all this cold weather we have been having. If the Catalytic Converter was supposed to last the life of the car and previous to this I ran a Nissan Sentra S-E-R 250,000 miles on ONE Catalytic Converter, I don't think I could be THAT abusive. I'm convering a LOT of highway miles. Anyhow, thanks again! Will keep you posted.

pychogirlfrien,
 
Alcohol is usually used to pull water out of the tank, but it also raises the burn temperature, possibly pulling contaminants out of the converter or burning off excess hydrocarbons plugging the matrix, but I am unsure of that. In any case, when you pull the battery cable on most modern cars to include the Suzuki, it may or may not clear the codes in the engine computer, but it usually triggers a separate code caused by that removal. It also causes most cars to go back to a default tuning, which may be a bit sluggish for a certain number of miles. The engine light can stay on for a tank or two of gas, depending on circumstances. So, the old, "if the light comes back immediately, it is a hard fault" ain't necessarily so. Now, if you have a reader, that's another thing entirely. There used to be a simple trick to cause the lights to flash out a 2 or 3 digit code, but that doesn't seem to work any more.
 
Also, since you are covering lots of highway miles, you are putting very little load on your converter, because it is damaged most at start up and under acceleration, when the exhaust is likely to be fuel rich. The EPA only requires that converters last 100,000 miles if I remember correctly, so they are not guaranteed for the life of the car. If you keep the engine running reasonable cleanly and do not consistently run it for under 5 miles on cold mornings, the converter should last the life of the car.

The alcohol simply cleaned up the fuel system and the converter.
It made for higher operating temps as the previous post says which in turn rid the converter of deposits.
More than likely it was the "cheapie" gas that made the problem arise on an already older converter.
I drive 175,000 miles a year and I only run Chevron in my Suzuki, and either BP or Shell in my Chevy. I had two Toyotas I ran for 400,000 miles almost exclusively on BP fuel.
Keep in mind that now most of the fuel contains10 % ethenol, I consider this a bad thing. I add a fuel cleaner once a month.
Good luck to you and keep us posted.

aerio 2003 maintenance by brianm6

Just got a 2003 aerio w/ 56K miles, but no owner's manual...would someone help, please: need to know the grade/type/specs of the oil recommended for this engine (2.0).
Had the car 3-4 days now, not many issues to report except that the owner before me put 2005/60/15 tires on it (really louse and noisy ones at that) and they drive me crazy, will be changing them ASAP
thanks

My 06 Aerio uses either 5-30 or 10-30. (either is fine according to owners manual)
SM grade oil.
 
I have an AWD so I am not sure on the transmission, but the Suzuki website says
for an 08 with a 2.0 engine to use SAE 75W90 for a manual transaxel.
 
Here is the # for Suzuki 1-800-934-0934 (Customer assistance center)
 
Hope this helps.

As has been noted on here before, if you don't have a good local tire dealer, you can get good tires from tirerack.com, dirt cheap. I bought a set of the following tires for $188.00 plus $41.26 for shipping all four from Louisiana to Texas.
 
215/50HR-15 Kumho ECSTA 711
 
They have warehouses around the country and I think in Hawaii and Alaska that limits the shipping distance and therefore the cost. In any case, that was $47.00 per tire plus $10.31.5 per tire shipping and $14.00 per tire mount and balance at my local tire store, so for a little over $71.00 per tire, I had a really good set of tires that no local store would sell to me for less than $90.00 per tire plus mount and balance, so I saved $33.00+ per tire and I did not have to pay sales tax. That size is less than 0.08% different in diameter from the 195x55x15 tires that are standard on the car, and they are smaller, correcting the very slight upward error of the Suzuki digital speedometer. The 205x60x15's are 5.2% larger than the OEM tires, meaning that they register 3 mph low at 60 mph, and that could end up costing you a ticket. The 215x50x15's are the only size that is really close in 15's, though you can use 185x60's and still be less than 1% off. If you don't mind approximations, you can go to an online tire calculator like this one:
 
http://www.miata.net/garage/tirecalc.html
 
You still have to calculate the percentage difference, but you can get what you need. The 215x50's rub very slightly in extreme bumps, but I haven't had any problems except when I got into some sticky mud that pushed off my decorative moldings, but that might have happened anyway with the mud that I was into. The problem with the 185x60's, if you can get them, should be checked for load capability and you will get some distinct tail end float in hard cornering. That's why I went to the wider tires in the first place...the regular floated out too much for my taste. Also, the Kumho's I mentioned are uni-directionals with a V sipe, which makes them handle really well on wet pavement, which standard all-weathers do not. The standard tires on the Suzuki might as well be water skis in the rain.
 
Good luck
