Hello, everyone!

I own a 2017 Kia Sportage SX Turbo which now has almost 58,000 mileage.

While writing this, my Sportage will be scheduled for an oil change within the next couple of days.

I was looking for some Engine Treatment and I found TUFOIL ENGINE TREATMENT on the internet.

Also, I saw the product SEA FOAM SF-16 GAS AND DIESEL MOTOR TREATMENT.

I found out that these two products were already in the market for long now (especially Sea Foam).

Does anyone tried these products on their Sportage?

What I am most concern is that... Does these products improved Fuel Efficiency on your Sportage??

Thanks for your response.

I'm not automatically opposed to additives, and KIA does recommend the use of injector cleaner, but I would suggest for the engine oil a premium oil of the appropriate viscosity is probably about the best you can do.
What I do for the fuel is use about 1/2 oz to 1 oz of Startron each time I gas up. This is a fuel stabilizer that also cleans anything coming into contact with the fuel. Being much milder than a fuel injector cleaner, it works much slower, which is why I use it all the time. Prior to this, in previous vehicles, I used Sta-Bil (various types as they became available) going back to about 1996. I have yet to need any fuel system maintenance on any vehicle and have not needed to replace any catalytic converter.
For the SX, which ordinarily tends to build carbon in the combustion chambers, I believe this regimen is critical. If carbon builds up, it actually increases the compression ratio which can cause spark knock, which is something you really need to avoid with this engine. It can also glow with heat and cause pre-ignition which is basically the same thing.

These three I like....

Lubegard Bio/Tech Oil Treatment
Techron Concentrate Fuel Treatment
CRC GDI Intake Cleaner Spray

But I never measured any of these above for fuel savings.
Have also used Lubri-Moly MoS2 Oil Treatment and will be testing STP Ceramic Oil Treatment this summer.

At 60,000 miles and zero problems I decided to add a bottle of Techron. I was way up in the mountains in a parking lot and thought it skipped a beat while idling. I've always bought good Valero top shelf 87% gas but thought maybe I got some bad fuel. I used the Techron with 10 gallons of Shell gas and think it may have helped. I'll do it one more time because I have a $10 credit at the auto store. I've never believed in wasting money on additives but with a small engine and a turbo it can't hurt.

I use Techron or Seafoam about every thousand miles, staybill in vehicles that are going to sit for longer than a couple of weeks. Mileage was never the reason.

I've never used additives in any of my newer cars over the past 50 plus years and have never had engine issues. Use good top tier gas and change your oil as recommended by the manufacturer -- no more often than that -- and things will be fine. Years ago, additives were a big thing but today, with all of the additives already in oil and gas, I think they are just a waste of money. The only exception is when they are recommended in your maintenance manual (not by your service manager who is trying to sell you more stuff).

I am a firm believer in Staybil for anything that is going to sit for a period of time. I use Staybil 360 when I had the boat and PWC as it also has a dryer in it. The bikes, sportscar, snow blower, lawnmower, and gas trimmer all get Staybil. I know to many people who have had to have carbs cleaned to get their equipment working. Fuel injection I don't know if it is needed or not but it doesn't hurt anything.

Yes, I've used Staybil for when you DON'T drive your car. But even if you fire up your car once a week and get it up to temp, you won't need Staybil. Now when I had a snowblower/lawnmower, it was a necessity.

If the oil treatment smooths out your engine even more - if it improves gas mileage - if it quiets the engine even more, then it is worth using.

One may not add treatments to the oil at every oil change. It all depends on the benefits the oil treatment keeps bringing. Should you hit a ceiling on the benefits, then try an OCI without it and monitor the results.

For newer cars with full synthetic oil, this is just a myth and untrue. Your oil contains a lot of additives -- and if you've ever tested your oil at the manufacturer's oil change mileage, you'll know you have plenty of additives left. It is only in the far back olden days when we were all using single weight oil that additives MIGHT wear out. Anyone who continues this belief just doesn't understand oil technology today. They theory behind added mileage is the same. This theory is that additives reduce friction and thus improves mileage. Today's full synthetics reduce friction as much as you can get and you won't see any measurable increase with an additive. If an additive quiets your engine in your current Sportage, then your engine needs to be fixed or you haven't taken care of it. Like I've said before, if you don't believe this is true, have your oil tested. Additives do wear out, but oil manufacturers put enough additives in your oil so that the amount available when you change the oil is more than enough for your engine. Manufacturer's do test each engine for recommended maintenance intervals to insure the oil additives are more than sufficient for that interval. That is the reason the oil change interval is different for the turbo than the NA.

Don't waste your money on additives unless they are recommended in your manufacturer's manual.
