Never used it in my 300CD or my 300TDT either. I guess I do a lot of outlying. No doubt I buy fuel from the only dealers who care enough to blend their fuel properly.

Since I'm an outlier, you must have hundreds, maybe thousands, of engines that have been ruined, totally ruined, by the lack of fuel lubricity. Yet these pages are all but devoid of examples of people replacing failed injection pumps. Show me just ten of those failed IP's, with evidence that the problem is excessive wear, and I'm convinced.
