*Techron Concentrate* great for older Jeeps

(there's no spot fuel additives and I use it in my 94 GC, so I'm putting it here)

Synopsis:

Techron Fuel System Cleaner is probably the best fuel-system additive for gasoline powered cars. It keeps fuel injectors clean and reduces carbon deposits.

Performance:

In reality, it's probably only a degree or two better than competing products, but I've seen enough research (not a ton, but enough) and used it long enough in my own car to appreciate its benefits.

Gasoline quality can vary quite a bit in some of the rural Northern Plains areas we visit, so the added protection and cleansing of the Techron keeps me happy. I've never had any fuel-related problem in our '94 Grand Cherokee or our '86 Dodge Colt Vista; the former has used it since new, the latter since '93 or so - the Vista ran a little smoother and accelerated a bit faster after usage. We never had any engine run-on, pinging, or loud/unrefined idling with usage. Using this kind of additive has also enabled us to keep using regular unleaded without any power loss or hesitation even as the engines have hit high mileage.

Value:

We rationalize it by thinking (a) all 3 Detroit automakers use Chevron gasoline with Techron for their testing, including EPA, (and the nearest Chevron market area is in KY - they have it shipped to MI) and (b) a 12oz. container only costs the price difference between a tankful of regular and premium and only needs to be used every 3000 miles.

We know other people who also travel to remote areas where gasoline quality can drop (especially in winter) and they have had a fair share of fuel-related repairs. I guess we're just buying that extra insurance and it's paid off so far...

Sidenote/Oil Additives:

I feel that fuel additives are, in general and when from a respectable manufacturer, beneficial if you don't regularly use a high-detergent premium gasoline. I prefer Techron, but have heard good things about the Valvoline SynPower additives. Oil additives are always a bad idea. Most, particularly Slick 50, have PTFE (Teflon) and DuPont has actually sued to keep them from advertising PTFE's use. It tends to build up in the engine and carbonize.

My suggestion to anyone who is considering using oil additives is to use a higher quality oil or a synthetic (though not Castrol, which is always under FTC investigation for leery product claims). We have known and loved Mobil Delvac 1 for older engines, especially diesels.
