o.k. This likely is talked about in other threads, but I'm bringing it up again, as I found some interesting info, researching for answers myself.
It Seems that is is NOT Bad for our engines... But I'm looking into it further... Here's some info from a guy "Auto Channel" who seems to have done tons and tons of research on this topic already and is an Officianto on the topic.
His reply to one of my questions to him on some youtube channel video I watched.
It seems that our engines are designed for this and unless you leave your car sitting in a garage while you're away on a long vacation, it's not an issue at all. More for small engine tools, sure.
So, I'll do a bit more searching, but it seems safe to just get premium gas from any reputable place and not worry about it, except for if you want the improved fuel economy that does come with pure gasoline, of which I've seen couple other reviews on which do prove it's true, but when you factor in the cost of the pure gasoline, to the 2-3 mpg you get, actual cost per mpg is still cheaper to use the 10% ethanol version.
I've put out a request to this guy for more info on LSPI (low speed pre-ignition) and see what he knows about this.... I'll add that to this thread.
Sure, we can find reports stating cases for both sides, but this sounds real good and he claims many of the anti-ethanol info comes from the oil companies agenda.. starting from way back in the early 1900's.... hmm... ?

@RPM Auto Reviews Thanks for your questions, although it appears that your last question was truncated. I'll answer as best I can, and then if it seems I didn't understand the last question sufficiently, please restate it.
It's not just that "today's" engines have been designed to optimize gasoline (regular or premium), nearly all passenger vehicle engines mass-produced for the American market have been designed to optimize gasoline. Exceptions to this would be Ford's Model T and a few other early automobiles whose low compression engines were designed to run equally on multiple fuels (the engines could be manually optimized via timing and carburetor controls). If I understand the general nature of your questions correctly, you are asking if modern engines can use up to E10 because the manufacturers did something different after (let's say) 2002, or because the addition of up to 10% ethanol is insufficient to make a difference? The defacto answer is that 10% ethanol is not sufficient to cause any difference in the operation of any gasoline-powered automobile (with the exception of the possible loss of some miles per gallon), therefore no changes had to be made by the manufacturers. This is not just true with 10% ethanol, it is true with 15% ethanol and with 20% ethanol, and even higher ethanol-gasoline blends. We know all this because E10 is not just the fuel used routinely by vehicles produced after 2002, but by all gasoline-powered vehicles. When the EPA granted E15 use in 2010-11, they acknowledged that government labs also tested E20 and found E20 to perform equal to E15 and E10 (earlier testing had established that E10 performed equal to E0). I know this because I personally asked the question to Gina McCarthy, lead spokesperson for the EPA, on the press conference. You can hear the entire press conference at
. My question comes in at the 17:30 mark. In addition, the formal government report on the testing of E15 and E20 (that found no operating difference) can be accessed at https://www.nrel.gov/docs/fy10osti/46570.pdf
We also know that virtually all mass-produced gasoline-powered vehicles manufactured before and after 2002 can safely and efficiently use E10, E15, E20 and at least up to E30 because the vehicles on the road in Brazil are virtually the same as the vehicles produced in North America, Europe and Asia. And the mandated minimum ethanol-gasoline blend in Brazil is E27. Brazil has been mandating E15 and higher since 1978. Every time they moved up the ethanol level they did not issue recalls to adjust all the vehicles registered in Brazil, they simply adopted the new minimum levels after significant testing to insure that the vehicles could safely and efficiently use the higher levels. We also know that European passenger vehicles could safely and efficiently use ethanol-gasoline blends up to at least E30 because ethanol-gasoline blends were sold throughout Great Britain and the rest of Europe for more than six decades.

The use of much higher level ethanol-gasoline blends is a slightly different issue because the use of E85, for example, usually requires an adjustment to the air-fuel mixture. In modern ICE vehicles (what you refer to as "today's engines") this adjustment is accomplished by the on-board computer to recognize the higher ethanol content fuel. Vehicles with carburetors would usually require a manual adjustment. However, as studies have shown, the parts and components used in comparable flex fuel and non-flex fuel modern vehicles are the same - the only difference is the computer software. The following two videos address this:
You ask two more questions: The first concerns harm or damage done to engines by ethanol. The short answer is that ethanol causes no damage to engines that isn't already caused by gasoline and aromatics. The reason for this is that ethanol is compatible with more types of rubbers, plastics, and metals than gasoline and aromatics. If corrosion is occurring, it was first caused by the effects of gasoline and aromatics. You can read more about this in "Why Do Small Engines Suffer From Ethanol Problems?" at

The 2nd and last question relates to premium gasoline. Premium gasoline contains higher octane than regular gasoline. If a manufacturer says that you should use a premium gasoline or mid-range gasoline versus regular gasoline, then you probably should. However, in America, mid-range and premium gasolines usually also contain ethanol. In fact, they may get their higher octane by using ethanol to raise the octane level. Some people are unhappy paying more for mid-range and premium fuel. One way to get around this is to "splash blend" your own higher octane fuel by mostly using E10 and then adding in a calculated amount of E85. If you live in a market where E15 or blender-pumps are available, you won't need to splash-blend your own concoction. Remember that E15 is basically mid-range fuel. If your new Kia Stinger is brand new (not just 'new to you') and it is under warrant, then follow instructions (not because some damage will occur, but because you don't need to argue about voiding the warranty should the issue come up). If you use E0 regular gasoline or E0 premium gasoline you will probably have to add one of the aftermarket products I talk about in the essays above every time you fill your tank. The extra cost of this additive will be much more expensive than using an ethanol-gasoline blend. Since you are involved with reviewing cars, you may wish to start experimenting with ethanol and different ethanol-gasoline blends. This is what I did for many years with literally hundreds of cars, and it's one of the reasons why I know so much about this topic. For much more information you should also read my 600-page book, THE ETHANOL PAPERS. You can do this at
