I have a 13 Chrysler Town and country with a 3.6 liter. It has 135,000 miles on it. I am thinking of using a fuel system cleaner on it but haven't used it before. Are there going to be negative side effects after this high mileage? I am using the Techron brand.
Thank you.

Unless they are gummed up with ethanol, it won't do anything for you. If they are it might speed up unclogging them, which would happen with enough use. But injector clogs are often small particles that get past the filter screen, and those aren't going to be cleared by a chemical.

Techron is, in my opinion, one of the better fuel system cleaners. It is the only fuel system cleaner that was actually called out in Chrysler service bulletins.

The most frequent use for Techron was to remove deposits on the fuel level sensor (false fuel level readings and then running out of gas - been there - done that). A bottle (or was it two) of Techron and the fuel level sensor was reading good.

It is true that all gasoline has a minimal level of detergent additives however there are typically higher levels in the national brands (more additives - higher cost). For example, Top Tier is a marketing campaign that requires higher levels of additives.

Techron is the only effective fuel additive. Will clean intake valve and combustion chamber deposits. In my experience the only cure for injectors is replacement. I've run into that with both the 01 and 09 at 160-180K. They have always been run on top tier gas. They were setting codes for misfires which turned out to not be coils.

It has more cleaners in it than say Sam's Club which is not a top tier fuel.
Not necessarily so. Top Tier is a marketing campaign that gas retailers pay into in order to put the Top Tier sticker on their pumps. In order to be considered Top Tier, the retailer submits their blend of additives to Top Tier and get approval. Does not mean that other gas retailers do not meet the Top Tier criteria, only means they do not wish to pay for Top Tier advertising.

If you think you need a good cleaning, run a tank of E85 through it. Ethanol is a cleaning agent and will scrub your fuel system clean.

E10 is the reason we really don’t need fuel cleaners anymore. It’s also why vapor lock is nonexistent as well.

I used Seafoam in my Jeep when I stored it over the winter. I did not run ethanol gas in the Jeep due to its age. I really liked Seafoam for the purpose of winter storage. I also use it in my small engines, since it can take a year to use up my 5 gallon can. I never have startup issues in the next season.

Well, I'll use 1 can of Berryman on the junk I buy, because I usually don't know how long it's sat for. It doesn't really make sense to use on any sort of schedule though.

White van here was originally looking pretty filthy.

On the subject of fuel additives, what’s the consensus on “Fuel Juels” from True Brand? Recently my work here at Jiffy Lube has incentivized us to try and peddle the stuff, but I’ve never heard of this brand nor their “universal power steering fluid” that we use as necessary.

I doubt the stuff causes any harm; but I also doubt it really does anything other than lighten customers’ wallets. I stay skeptic with Lucas‘ oil additive as well, but I’m a bit of a purist with my van and some do say the stuff helps.

Did a search on 'fuel juels' - switch on your BS meter

True Brand Fuel Juels is a patent-pending formula that utilizes 3-Phase Brownian Motion Technology. This creates a time-released effect that allows Fuel Juels to restore fuel mileage, increase compression, fight ethanol, and remove water for up to 6,000 miles – approximately 12 tankfuls of fuel!

And cures the common cold \sarcasm off

In my opinion, there is no universal <insert component> fluid. There should not be a need to add power steering fluid unless there is a leak.
