Back in the '80s I was introduced to Mix-I-Go, a gas additive produced by Bell Labs (now Bell Performance). By using their gas and oil additive I was getting astounding mileage from my '74 Audi 100LS (as high as 38mpg). Somehow over time I quit using it (I moved far away from my local distributor and it was too much hassel to order it.) Anyway I have once again become interested in squeezing the most out of my gas and preserving the life of my car. Since joining BITOG and reading up on things here my memory was jogged about Mix-I-Go. I have not come across it's mention anywhere on BITOG. Are there any fellow BITOGers who have heard of or used Bell's products? If so please chime in and let us know your opinion of their products. For those unfamiliar with them, here is a link to their website. http://www.bellperformance.net/products.shtml
