#216 of 245 2002 malibu ls, catalytic converter needs to be changed? by goldmalibu02 Mar 05, 2007 (4:50 pm)
hi,   i bought my 2002 malibu brand new and it has 30,000 miles on it. last week i went out of my driveway in reverse into about 7-10 inches of snow at the end of my driveway. since then i am noticing a different sound coming from either my exhaust system and my converter. i looked underneath and the catalytic converter is rusted. no smoke is coming out from anywhere but my car has a unusually lower rumble sound than normal.   any idea if i am right on this and how much does it cost to change a catalytic converter.

Replying to: kpugh2 (Jul 21, 2007 1:09 pm) I assume you're WAY beyond 0% on your OLM. I sure wouldn't be comfortable with this. Are you using Amsoil? Replies to this message: kpugh2 (Jul 22, 2007 11:07 am) maxx4me (Jul 22, 2007 11:33 am) Mr_Shiftright (Jul 22, 2007 11:35 am)

Replying to: csandste (Jul 22, 2007 7:28 am) I have been using AMSOIL for many years. It is in all mygas/diesel engines. The old saying " This is not my first rodeo" Have been doing extended drains since 1982 when I started to go 7500 miles.

Replying to: kpugh2 (Jul 22, 2007 11:07 am) he, he...you probably suffered from a traumatic experience at one of those "lube" places. Their shoddy workmanship is enough to swear anyone off oil changes. I change my Maxx every 6k with Mobil 1. While I recognize this may be overkill, the Maxx is so easy to change, I'm done in 15 minutes. I use the 6k interval as an excuse to crawl under my car and look for problems. My mechanic has always marvelled how I catch mechanical problems way before a part could ever break down. Essentially, I'm doing a visual inspection of the whole car each time I change my oil. Hopefully before I get too old, we'll be done with oil, and I won't have to worry about fluid changes.

Replying to: kpugh2 (Jul 22, 2007 11:07 am) Well I guess there's the question of what one CAN do as opposed to what one SHOULD do....it would make me nervous to push beyond 15K oil changes even with synthetic. Maybe on older cars or less valuable ones this is a risk worth taking but with an engine worth $15,000 I haven't got the guts.   Perhaps will periodic oil analysis I'd be more comfortable doing what you are doing. But for the average bear, they might not be as conscientious as you are.

I am a original owner of a 1999 Malibu LS. Despite bad reviews - this car has done well for me and only has 60K miles. A few service questions:   1. I still have the original spark plugs in the car! I never have had a tune-up. I am curious if postponing this has done any damage or costing me gas mileage? Of course, when I bought the car they said 100,000 before first tune-up but it has been almost 8 years.   2. I have never done a transmission service. What is the normal timeframe for conducting these?   3. Given the age of the car and mileage what major repairs should I be prepared for? I have already done the intake manifold gasket repair several years ago and the well-documented A/C problem repaired.   Any feedback or thoughts are welcome!!!   Magnus Replies to this message: csandste (Jul 29, 2007 5:22 pm)

Replying to: mjohns7861 (Jul 29, 2007 8:13 am) I own an '04 Maxx, essentially a different car, so I'll pass on this. I would wonder how hard the plugs would be to get out, however--but 12K a year would get you under the GM service so I guess things should work.
