The truth about gasoline direct injection | How to care for your GDI engine

Please note that when I called my Kia dealership, they only stock Techron for fuel additive. FWIW, there are other brands of fuel additives but I will stick to a “more conventional” additives that I’ve used in my past vehicles and proven harmless to me. As always, when it comes to our cars, especially my Telly, the adage, “first, do no harm” will go a long way! Thanks!

I have used bg44k, but recently started using Hotshot Secret Gasoline Extreme.

For even more added protection, when you have a choice you can buy gas from a Chevron or Texaco. Those gas stations advertise Techron as the fuel additive they put in their fuel.

So this is the official fuel cleaner that I was sold at the parts and supply at my local Kia dealership in Huntington Beach. When I go to the Carson dealership they will not sell it to me there saying something Kia will not let them it's an exclusive deal. I think it's like $36 a can, expensive. Can't find it anywhere out there. MOC fuel injector cleaner

How often do you use it or what is the recommendation from the dealer ?

The Kia dealerships I have been to use Techron you can buy it for a few bucks at Walmart.

Sorry late reply, I think the Kia service guide said about every 10k miles. But the dealer wanted something like $60 to just pour a bottle in your tank which is a joke.
Also kind of crazy they charge $36 a bottle for this stuff. So I do it every 5k miles.

I think just do the techron or other high quality stuff, unless somebody has a professional opinion about gdi cleaners.

Just read through the manual, sorry if it has been already stated. If top tier gas is used, no additives are needed. If not, once ever 7,500k This is for normal driving. No changes noted for severe driving.

Is there such a thing as "overdoing" the detergent? Can this thing be addicting? Lol!

On a related subject....has anyone here tried an actual GDI cleaner like this Lucas Oil product?

Use Shell, BP, Exxon, Marathon, etc....all major oil companies are top tier. Walmart, Kroger are not top tier gasoline

Not all sations carrying the brand have top tier gasoline. Look nfor the to-tier sticker on the pump, and hope it means what it says.

I understand the benefit of additives in high pressure fuel system and am planning on either using top tier gas or keeping up with additives (probably both), but how does this help with carbon build up at the intake? That treated gas never runs through the intake port and my understanding is that the valves get build up because of that in the first place.

I found this thread to be particularly informative on the topic: Mass airflow sensor

My original post includes this statement: “Some other automakers have tried some engineering fixes. One example is a modification to the engine that allows it to spray a little fuel onto the valves themselves to act as a solvent and keep them clean.” This is what I think most carmakers did in their latest generation of GDI as a response to the issue of intake valves carbon buildup. It just makes sense! It’s a win-win situation for both carmakers and consumers! Carmakers can continue to offer their long warranties (Kia/Hyundai) and consumers trusting more (less repairs) and sticking to their favorite car brands! Otherwise, why continue with the same old engine design when it can be improved? So, along with proven old fashioned fixes such as severe versus normal maintenance (depending on driving habits/style)—mostly oil change intervals, use of Top Tier gas (or fuel detergent additives), timely (early is better) engine air filter and PCV valve replacement, we will have done an excellent preventive measures to mitigate carbon deposit buildup! Also many owners include fuel system service an important part of this preventive maintenance! Thanks!

Look into BG intake cleaning at your dealership. They use a tool and chemicals to clean the intake valves. I just had it done at my dealership while getting a recall done.

Ok great. Thanks. How many miles do you have on your Telly?

 

[Point37]

i have a few cans of bg 44k at home...probably use it in the telluride

About 35k

That is good for the fuel system and combustion chamber. It will no do anything for the back side of the intake valves where there is carbon build up.
