J.D. uses Lucas Fuel Treatment in 1987 VW Convertible

I have a 87 VW convertable that was running fine till I took it on a 400 mile road trip when returning from the trip the next morning I started it up to go to work. The whole drive to work it putted and was lacking power badly so I spent the day at work wondering what was wrong. Then putted back home a poped the hood looked at just about every thing and couldn't figure it out. So I talked to a friend and he mentioned how good of a product Lucas has been for him so I decided to pick up a bottle of fuel treatment and dumped that in and after I used about a 1/4 tank of gas could notice a diffence, so I thought wow its working by the time I had used the full tank there was no more putting and the car iddled steadily and ran better than ever before. Lucas is a great product and plan on using it often. Thanks!
