Did anyone ever installed fuel saving device like tonado or fuel maxx (ebay)? Will it be OK to install on VOLVOs? As long as it won't hurt the car I am going to install because I just bought one from ebay. I will only lose $17. Please someone let me know see if its OK to install on my 1999 S70. There are so many negative comments but I also heard it works on certain cars.

Snake oil....avoid it. It will be a disappointment.

Im fairly sure that the Tornado is a scam.

Tried 2 tornadoes on two different cars with the same results---> ZERO increase in gas mileage.
