Question for the engine guys
 
Does anyone use, or have information about, fuel additives like Chevron Techron, STP, etc etc etc?

Do they actually clean, restore performance, and/or increase fuel economy? Are there any risks to the engine or other specific reasons to not use them?

Fuel additives is a very wide term. Some are for only cleaning the fuel delivery system. Others like Techron are multi purpose. They not only clean the delivery system, but clean off carbon deposits on the intake valves, etc, for better driveability. Read the bottle for the what that product is designed for. I prefer the
products that are very similiar to Techron when needed.

With modern vehicles and quality fuel, I'm not convinced such things are really needed. The only one I've ever used much is the Techron, and even then only with older vehicles.

I'd say all of the brands you mentioned do work, but if you use Top Teir gasoline, you shouldn't need any "extra" detergents from additives. But if you want to use them, they certainly won't hurt anything.

I personally use STP Total Fuel System Cleaner in my own vehicles every 20,000 miles.

if you buy good gas then you dont need to use that stuff much. be especially nice to the hemi :D in the fuel department. also, you guys might consider a catch can if you can rig one up for the wk2 hemi. there is a famous CMR Tuner who custum tunes 100's of cars and sees data logs all day long. Johan from Diablosport. he'll tell you 2 things to keep a modern day hemi going strong is 'catch can' and 'good gas'.

google hemi catch can; or ask ANY SRT8 driver on here.



in my older jeep, 98 xj 133K, I use B&G 44K. napa sells it about 25 bux. once a year.

Typically buying "brand" fuels consistently from high-volume stations and keeping short driving trips to a minimum will keep your valves clean without adding any additives to your fuel. If you take lots of short trips and use cheap big-box-store fuel you are not helping your engine keep clean internally. The brand name fuels add seasonal additives to their fuels to help driveability and to help keep your engine internals clean. They biggest factor though, is minimizing short trips where your engine never completely warms up (important for your oil service life too).

The GOOD thing about the engines for the WK2 is that they are NOT direct-injected. While we don't benefit from an incremental improvement in power and economy from direct injection, we WK2 owners will benefit by not have the valve deposit problems down the road that all direct-injected engine owners will have. On direct-injected engines there is no fuel flowing over the intake valves to help prevent deposits from forming, so over time they develop a significant carbon buildup requiring an expensive service. Again, in all engines this can be minimized by avoiding lots of soccer-mom/grocery-run types of short trips.

wasnt there a TSB issued by Chrysler concerning the use of "additives?" i remember that it said it did something to the Magnum motors, and harmed the MDS on newer ones. ill have to dig it up, but i never ever use them in any of my cars. i think they do more harm than good. i have no evidence of this, but first of all, i cant justify spending $12 for 7 ounces of a liquid that i dont know if its doing anything but running thru my fuel lines.

Appreciate all the input, guys.
Thanks!

Carbon deposits will accumulate and dirty injectors can be part of a driveablility issue with the E-10+ fuels which burn colder and develop less thermal energy. A bottle of Techron type product will help once in a while.
