When I first got my 1980 240 TCane showed me how to do the Diesel Purge..
Afterwards we both felt that it ran smoother...

What I can't figure out is the thinking process of those of you who said it did not help your cars and it was thus a waste of time and money for others...

This is just like the situation with using Trans-X... which I have had dramatic success with on several old cars....

Both of these items are about $20 to try and I have seen no evidence that trying it without it being " needed" has done any harm.

If it does not cure your problem then a build up of varnish was not the problem with your vehicle... that is all either of these products claim to do.. dissolve some built up varnish in Very Small places where small build ups are a bad thing...

The fact that it did not seem to help your particular car means THAT WAS NOT THE PROBLEM WITH YOUR CAR... not that the ingrediants were proper or could not be effective if that had been the problem or that the concept of using a varnish remover was not legit.

The Philisophical concept here is " you can not prove the null hypothesis"...in case you want to look it up...
