Is Decarb procedure really needed?
I have a 1999 with 50,000 miles on it and I need to change the oil. Do I really need to do the decarb procedure on the motor? What are the pros and cons. Thanks ahead of time.

If you are talking the Seafoam method, I would do it. It can't hurt. A ton of junk comes out the tailpipe which can't help the car staying inside. I had a dealer do it for a Dodge and it made a significant improvement in my milegae (2 MPH). It obviously cost more than a can of Seafoam but since you're going to do the oil might as well do it now.
But on the other hand the engine ain't gonna seize up tomorrow since you didn't do it.
mark it up as PREVENTATIVE maintenance that is pretty cheap to do.

The smoke issue is pretty embarrassing. Even if you get out of your neighborhood and drive it everyone will be staring and not with the typical "look at that hot car."
Now I do it in the afternoon or evening, let the car sit overnight and get out and drive it before daybreak so no one notices. Then I change the oil and wash all the black crud that is stuck to the rear of the car.
You will be amazed at what comes out the exhaust after a top end cleaning.

I did the seafoam this weekend on my c4 with 150k on it.
It did nothing.
I'm assuming this is because I have run real bp ultimate since I bought the car.
Dont know how it works, but it is proven to remove valve deposits left by other gasolines.

Do I need it? I have 23,XXX miles on a 99.
Hey guys,
Is there a certain milage thing involved in this, where you would do a decarb. Cars with low miles need it or not - its 99 though, with 23K miles. Does any of this hurt the valves, intake, rings etc. It seems pretty harsh chemicals to be used in a High end car.
I was told by an auto parts specialist. He said why use Seafoam for Decarb, why not use the product mainly designed for car engines... So, he suggested the "PROFESSIONAL 3-STEP FUEL SYSTEM MAINTENANCE KIT, by Berryman CHEMTOOL. It consists of 3 cans in a box. Price: $24.98 from Kragen.
Has anyone come across this product, used it, or know anything about it Vs Seafoam....?

I bought a gallon of Seafoam at O'Reilly for $43 and change.
I have a '98 M6 coupe now and just put 12 ounces of Seafoam in a half full fuel tank and 8 ounces in the crankcase. Going to run it for the next three or so operating hours, drain the oil, and put in a new filter. I have about 30 minutes on the engine so far and can't tell anything yet.
