Fuel Injector Cleaning

Wanted to get fellow owners take on the value of getting the fuel injector cleaning service done by the dealer. I've been struggling with 10-15% lower gas mileage over the past several months on a fairly common four hour trip I do. Last oil change the dealer said they didn't see anything wrong out of the ordinary and actually commented that the cleaning isn't usually needed at my mileage (65k) but said it could help if I wanted to do it. They weren't super pushy.

So is it worth considering? Cost is about $100...wondering if I should bite the bullet or see if the spark plug change I have queued up fixes this first. Thanks for the advice!

$100 for what? Sounds like BS.

Dump some techron in the tank if you like, but be wary about giving the dealer $100 to do something to 'clean your injectors'. Some of these dealers are lil Pirates - charging $100 for things like in cabin air filters.

Re: Fuel Injector Cleaning

Yea it seemed high to me, my thinking is maybe it's just the spark plugs showing their age and perhaps a dirty engine air filter..?

since you have the older style spark plugs due every 30k plugs could make a difference depending on the last time you had them done. if you had said 2014+ plugs would not likely make a difference as they are 100k plugs.

Word. Any thoughts on the fuel cleaning impact?

I'm not a fan of wasting money on a fuel injection cleaning service I think most of those they perform are unnecessary. If the car is coughing and sputtering it may be worth a try but if its running fine with decreased mileage there's other things id do. Make sure your air filter is clean, make sure your tire pressure is set at what's indicated on your door panel, if plugs are beyond 30k old change those. if you want to throw a large bottle of Techron in that wont hurt and is only a few dollars instead of $100. The hemi specifies 89 octane if your running 87(which is fine also) try changing to 89 but don't run 91 that's a waste of money.

Got it. I'm not having any of those other symptoms so I'll do the plugs first and see how that goes. Noticed that the maintenance schedule also says to replace the engine air filter at around 64k miles. Should I do that regardless or only if it's dirty?

the engine air filter should be done at least every 30k that's the max. how quickly it gets dirty depends a lot on the conditions you drive in. I do mine more like every 20k. they are cheap so if its been a while go ahead and change it. an air filer that is caked and clogged with dirt will reduce your mileage and performance.

Re: Fuel Injector Cleaning

A fuel injector cleaning should include a product that will clean the carbon off the intake valves. Don't let any shop use a product that's first component is alcohol as it's a cheap solution. $80-100 hasn't been an unusual fee. Purchase the large bottle of Techron or Seafoam ($10 each) and pour in the tank. Check the air filter and replace when dirty. Spend that $100 on the Iridium spark plugs if you plan on keeping the Grand.

Re: Fuel Injector Cleaning

Change the plugs first? Not me when a pour-in product may work.

I'd try this first: Amazon.com: Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner - 300 ml: Automotive
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Sent from Maxthon Cloud Browser

And yes, replace the air filter.
