I went back and read it again and I can see your point about it being an ad for Driven. But I thought it still had some interesting points, which is why I posted the link. I don't think they were saying a carb is superior tho, just different, and may not be as susceptible to LSPI as a DI engine would be. There must be something to this type of analysis tho because one of the primary advantages to the new GF-6 oil spec is to prevent LSPI. Whatever the cause is, its a real thing and if I have any catastrophic engine failure (tuned or not) i'm getting a new engine under warranty i'll tell you that.Just some thoughts. I'm a skeptic. I don't like articles like this that over mention one companies products. Driven's stuff may be great, but mentioning it over and over doesn't lend credibility. Another thing that worries me. All this money in labor and oil and fuel and they can't find good fuel? Why not order some? They admit they are having detonation issues but then try to pick the results out of the weeds. That is an awful lot of time and money to waste with an uncontrolled variable, which of course was fixed with Driven's products ... another placement ad?
Finally they claim that the sodium is the cause of more knock events, but the data shown in the images seems to contradict the claims in the article. I hope I am just missing something or reading it wrong.
I've been through almost every class EFIU has to offer. They are legit and some of their stuff is good. But they can be old school dudes, and the desperate attempt to illustrate that a carb is still somehow better than EFI/DI doesn't surprise me.
I can believe that oil choice could have an impact on the combustion process. But real combustion analysis is very high tech and requires a lot more than the factory knock counts and some dyno runs. If this really plays out to be true, it really means no factory warranty if you use other oils. I have an open mind, but I really hope it isn't true.
