So far I have not seen any auto part stores carry Redline Diesel Treatment in my area, as well as different parts of the country that I frequently travel to (Seattle, Vegas, Dallas).

The local MB dealer gets $6.00 a bottle. A dealer in Tacoma WA charges $8.50 per bottle.

I found a source http://www.importpartsspec.com/shop/ that has it at your door step for $3.99 a bottle + shipping.

If you have a better source, please post it.

Thanks
