Fuel system chemicals- are they necessary??
Is this stuff really benefical, or just hope in a bottle?

That is the only fuel additive in gasoline engines that I support.
But, this world isn't perfect and everyone gets a bad tank of gas now and then whether you realize it or not. The fuel is either old and starting to chemically decompose or it's contaminated with water, etc ...
Two of my co-workers had to have their cars de-carboned this year ... and that wasn't exactly cheap.
I use a couple bottles of Red Line Complete Fuel System Cleaner and isopropyl alcohol each year to keep everything dry and clean. Occasionally, a bottle of Chevron Techron goes in the tank as well. All this stuff (I spend about $15 per year on it) is VERY cheap insurance.

I heard BG 44K is great in diesels also (from some in tdiclub.com)
I'm guessing using $10-15 worth of additives each year vs. a professional treatment every 5 years or so is a wash in terms of cost.

My 87 Ranger has 214,000 miles my wifes 95 Taurus has 144,000. Ive never had any injector problems with either car. Both cars were bought new. I use 2 ounces in the gas every 2,000 miles. I've never had to replace the fuel pumps in either car. I'm wondering if the upper cylider lube is also good for the fuel pumps? The Taurus has one in tank pump. The Ranger has one pump in each tank & one frame mount.
On another car I used to use the Techron once every 5000 miles or so but cannot find that stuff cheaply anymore. I mix a batch of PI and gas and use that for the other cars every 5000 or so.
Again, probably wasting money.
What's amazing to me is that the engine sounds like everything is running with less effort.
