Carbon buildup, lower performance. Use non ethanol fuel 89 to 90 octane. Best performance with 93 octane.I noticed premium fuel is recommended for the 2.0 Eco-boost. Any downside to running regular?

Well, the other thing I know, at least here in SoCal, unless you buy the racing grades, you never know who actually made it anyway. A neighbor used to own a company that delivered "extra" to multiple branded stations.Carbon buildup is due to increased blow-by from higher compression and turbocharging, PCV re-burn, and direction injection -- since the valves aren't continuously cleaned by the premixed intake charge as in port-injected engines. It has nothing to do with octane -- except that with higher octane the computer can advance high-end timing, you can drive and rev faster, consuming more fuel, and causing the computer to enrich the mix to cool the cylinders -- which things do increase carbon buildup. The computer will retard the timing as needed for standard fuel and your driving habits. The critical thing in the fuel is the detergent additives -- as are promised with Top Tier fuels. Whether your usual driving performance in the 2.0LT Ecoboost "Twin-Scroll" is noticeably different on 87 or 91 or higher octane, who can tell without trying it out -- YMMV. 'Premium' also meant 'detergent' gasoline a long, long time ago, but not anymore. My bet is, 99% or more of the time I won't be in that part of the rev band where it makes any difference. Use Top Tier fuels, change oil and filter frequently, put in a catch can system if you're inclined. Have the top end opened up and cleaned out after some what, 30K-40K miles (not sure what might be recommended). Convince me that additives (Techron) or cleaners (Seafoam) do no harm and actually work -- I'm not, yet.

Rod? On what engine? What vehicle? 'Regular' did not cause this.It is all fun a game until you hear what sounds like a stick of dynamite going off and see a rod fly by............ Premium gas is cheap insurance in turbo engine against this(picture below).
PS. this does not buff out.......
It was a boosted aluminum head engine, what brand it was is irrelevant since I am sure we can find a failure like this for every brand that is boosted.Rod? On what engine? What vehicle? 'Regular' did not cause this.
No idea, I'm sorry -- still 54 days out until I can take possession of mine. :-( But, there are indeed specialized kits with the perfect bracket, tubing layout, and snap-on connectors, I think I saw a video of one for the 2.0LT EcoSport on an Escape, not sure I'm remembering that correctly. Very neat solution EXCEPT the can looked very small, and with no obvious easy way to drain it. The Engineering Explained guy on YouTube does an excellent comparison of some different types/quality catch cans.tRex -- which catch can do you suggest for the 2.0L Badlands?
I’m honestly finding it hard to take you seriously when you refuse to give information about the situation. What car? What year? What fuel? You are using that picture as an example of why we shouldn’t use low octane in a modern vehicles, but don’t actually give any information on what the picture is of. Seems fishyIt was a boosted aluminum head engine, what brand it was is irrelevant since I am sure we can find a failure like this for every brand that is boosted.
although the tech couldn't say that "regular" did this, he did say it definitely made things worse.
there was detonation in the engine due to bad gas and (allegedly) the computer couldn't compensate which resulted in a cascading of failures which made the engine go lean(really low AFR) and resulted in this.
In the majority of cases that I have seen where a hole on the side of the engine was the end result bad gas was a possible cause, owners always were out in the country and had to fill up with the gas that was available and still drove the vehicles like normal or they were in a rush and just chose the closest/cheapest gas station, a very small portion is due to owners trying to increase boost PSI to get more power beyond OEM specs.
I know that vehicles nowadays have a ton of safety features and should be able to compensate for bad/cheap gas by reducing power but as someone that likes to drive(not out of necessity but for enjoyment) and sometimes will find myself out in the sticks where cell signal is nothing but a myth let alone AAA, I do everything I can to make sure that my boosted engines run at peak efficiency and can get me back home.
Good gas and frequent oil changes are cheap insurance and make vehicles more reliable..
