Hi Frank I have just bought a 2001 Saab 2.3L Turborcharged Wagon and I don't know a lot about the history of this vehicle. It has 83,000 miles on it and it looks pristene to me and it drives very well. I am going to buy a few bottles of your product as I am sure it will do some good in terms of sludge removal. I did notice a slight little puff of blue smoke on morning startup only but only on morning startup. Can autoRX help this from occuring? I have 2 other new vehicles with less than 6000 miles each. I will try the RX on the 2001 Saab first and if it does it's thing like I think it will then I will order a few more bottles for them as well. I was impressed at the testomonials and fourm testomonials on your prodect. The major question I have is the Instructions for the clean and rinse with this product. If done wrong well enough said. Could you email me the exact proceedure for doing my Saab. I will order the product when I can be assured I am doing this right as I am a novice with cars. Also, how does one clean the auto transmission with this product. Thanks for your patience Frank and I look forward to using your product Regards, Gavin McKinlay
