Ecoboost engine question -- prevent carbon build up in the cylinder head?

[Barksdale123]

I am sure that someone here knows the answers. I am just guessing.
It seems like the turbo is always utilized to one degree or another. Cruising at 1500 RPM the turbo is working but to lesser extent? I have read about carbon build up in the cylinder head. Lesser extent that under acceleration? Finally, I had a mechanic that I used and trusted for many years. ( one time he apologized for not being able to fix the AC because he fired the AC guy who he found out was trying to juice the bill). Anyway he recommended Cheron gas because of the techroline. Also recommended a bottle or two of techroline and a run down the highway as a "Cuban tune up" his dad came over from Cuba in the first boat lift.. But I digress. Would running a fuel cleaner on a long (300 mile) trip have any beneficial cleaning benefits?

No, I don't believe so. Buy quality gas, they have detergents in them already.

Ford manual recommends only using Premium. There's a standard of "top tier" gasoline out there that purports to be best available and not too hard to find if you look for it. That's your best baseline IMO.

Couple threads here debating use of in tank additives you might review, but I won't revisit here to stay on your main point.

If you're using gas without the detergents, running it every now and again may help. Regular maintenance and never ignoring the check engine light would be best.

My dad (ASE Master Trainer in his day) always told me you don't need additives or fuel system cleaners as long as you do regular maintenance, use a good quality gas, and floor it once in a while after its hot and been running enough for the gas to soften it up to blow the crud out.

Ford recommends premium when you will be towing or hauling heavy loads. Otherwise, Regular gas will be sufficient for day-to-day driving. Also, note that any fuel additives to clean the head/valves, etc will not work on GDI (Direct Injection Systems) like our Ecoboost Engines.

Honestly even "blowing it out" isn't really that necessary on anything made in the past 20 years. I maintain a fleet that mostly idles around low speed and no issues on anything post turn of the millennium. Maybe if it's a diesel since anyone who tells you they can idle nonstop is out of touch with how much the filthy pigs can coke up modern particulate filters and variable turbos not getting worked.

With the Escape that is driven daily, we mostly use a mix of Walmart, Exxon, and Chevron. All 87. With the Maverick, I planned to use 91 simply because I work from home and don't drive but two to three times per week.

My dad drilled into me that if you keep your fluids clean and topped off, your engine will run 1,000,000 miles. That's the rule I've always used. Keep the engine fluids fresh (including the gas) and you should be fine.

Our engines are direct injection. Nothing but walnut blasting the valves every 20,000 miles or so will work on cleaning the valves. Fuel in our engines, is directly injected into the combustion chamber, therefore the solvents in the fuel never clean our valves allowing carbon build up. No fuel additive or cleaner will help that much with keeping the cylinder head clean.

Makes sense. Fuel directly into the cylinder won't clean what it dosent touch.

Wow, you got me there. Musta been a Senior moment trying to recall from memory without manual in front of me. Don't I at least get credit for correctly stating the Top Tier part? Reading directly from the posted manual page it doesn't say use 91 ONLY when "looking for every little ounce of performance" either now does it? There's multiple conditions where 91 is preferred. I happen to live at 6200' elevation, and we go from hot in Summer to really cold in Winter and we don't have 87 Octane here for Regular. It's 85 or 86. Some offer mid-grade at 88. I'm not worried about the extra cost of the Premium for best results in my case- but you do you.

I have used CRC GDI intake valve cleaner on my wife's 2015 GDI Honda CRV every 10,000 miles. Spray it thru the brake booster vacuum line on the intake while keeping rpm around 2000. I think it works well. I have a Mav hybrid so I don't know where on the Ecoboost engine you could spray it.



Might be a good thing to do, can't hurt.
