Actually the newer the car, the more important high quality fuel is. Direct injection systems are prone to deposits if a fuel of insufficient quality is used. As the CAFE standards require increased fuel efficiency, everything about the engine will have to function optimally. Using a Top Tier fuel or one that meets Top Tier standards will become more and more important.

The EPA specifies the detergency and oxygenate levels generic fuel must meet.

As as for whether fuel injector cleaner works, there's no need to use it if you use a Top Tier fuel which usually is about the same price as generic gas. It is not usually wise to use fuel injector cleaner as a preventative, using a high quality gas from a Top Tier supplier is all you need to do.

If you believe your injectors ARE dirty, adding a bottle of Techron is a good way to go. Thereafter use a Top Tier fuel.

I think they do help to a point, though I also think it depends on which brand you buy. Not to sound opinionated on this, but I am more brand loyal to the Lucas Oil fuel treatment as opposed to STP, a brand I used to buy which I found not to be much use after I tried Lucas Oil a few years back. I don't really know how well Z - Max, Slick 50, or Gumout work, since 2/3 of those brands I had mentioned are $10 - 15 plus per bottle. Though I think I'd try Gumout once to see how well it works.

Chevron Techron Concentrate certainly does. Use it on a tank where you'll do plenty of stop and go driving for maximum effect. Using it just before a long highway trip would be least effective.
Maximizing the hot soak time of the cleaner in the injectors gives the best cleaning.

The EPA standard for detergency in gasoline is often insufficient for cars with fuel injection systems and that's why a number of OEMs like GM and BMW formulated the Top Tier standard to insure that people don't have fuel injector problems. It's especially important to buy Top Tier standard fuels if one has a car with direct injection. I've read that several of the Top Tier members like Shell have had to reformulate their fuels to accommodate direct injection.

Because the EPA detergency standard is questionable, it is best to stay away from generic brands like Speedway and RaceTrac, especially when Top Tier fuels are the same price or only very slightly higher.

When we started building turbo cars in the '80s, some injectors would plug at the tip near the combustion chamber so Chevron developed Techron to clean them before they plugged. Now, most engines don't have any injector problems due to the Federal mandate that certain gasoline products have a certain amount of "detergent" in them. If you use a good gas brand that has detergent you should not have a problem of coking on the injector end.

Just use a Top Tier fuel like Chevron, Conoco, BP, or Shell and you won't need any fuel injection cleaner. The Top Tier standard was established to insure that any brand of fuel adhering to the Top Tier standard will have sufficient detergency to prevent fuel injector problems.

Just put a bottle of Lucas oil fuel injector cleaner into my 1998 Toyota sienna that has 226,500 miles. I've been averaging around 22 - 23 MPG. Will see how it does. I primarily run shell gas, but occasionally run BP, marathon or speedway.

Isn't HEET similar to ethanol? I don't see much reason to use HEET if you are using E10.
