  1. Not in this case. This is a direct injection engine and the build-up isn't in the cylinder, but in the port, which doesn't get any fuel passing through it.

  2. Octane of gasoline has nothing to do with performance. The octane is about the ignition point of of the fuel. Some cylinders are designed to run at higher compression points so that you have a more violent explosion inside the cylinder, which produces slightly more power and a slightly more complete burn, but if your cylinders weren't designed for the high compression, they will not compress the fuel enough when it's ignited and then you will have a more violent reaction, which may burn through your manifold or worse. You're best to run the engine on the octane it was designed for, no lower, no higher.

  3. 100 and 110 are aviation/racing fuels in North America. I've never seen a 98 octane fuel sold in the US or Canada. The highest I've seen is 93, which is a 98/99 RON level. In North America (US and Canada) and Brazil, the fuel pump octane rating is the average of RON and MON called the Anti-Knock Index or PON. In the rest of the world, the octane rating posted at pumps is just the RON. That's why the octane ratings in Europe seem higher than the ones in America. The fuel is the same. The way it's measured is different. For example = A 98 RON fuel is the same octane rating as a 93 AKI, so a 98 in Europe is the same as a 93 in the U.S./Canada.

  4. Ethanol is a corn-derived alcohol, which can be used as fuel. Traditional engines can only take a little of Ethanol, which stores much less energy in it than gasoline. E85 engines were designed slightly differently to be able to run on that less powerful fuel mix. The upside to ethanol is that it does also have less harmful emissions. It will NOT clean the engine though. It just makes the exhaust a little cleaner and it requires no crude oil to make as it's made of corn, making the industry less oil dependent.

  5. Costco doesn't refine its own gas. Just so you guys know, all gasoline retailers buy gasoline from 3-4 refineries around the country. Which one depends mostly on their geographical location, not their brand.

  6. This is on a Direct Injection engine?

  7. Except that this was never the case. When did you ever hear of a recall on a car made in the 80's or 90's that didn't involve masses of deaths? Never. It never happened. Actual car use (in mass quantities) has always been the only real world test of technology and always will be.

  8. Aren't these variable timing engines, so what difference would it make between 87 and 91 except loss of power?

  9. You could buy a 3 wheel car in Europe at one point too. It doesn't mean it's any good.

  10. Do you think using a fully synthetic oil will help the situation?

  11. Except the Escapes and Fusions with the EcoBoosts have an incredible resale value, so...

  12. Would this issue be improved using a higher octane fuel so that you have a more complete burn in the cylinder, leading to less carbon in the system?

  13. And you feel all that because...? Just plain ole paranoia? What do you know about engines?

  14. Direct Injection isn't a design flaw. It may be a flawed design, but it isn't a design flaw. It's a system.

  15. This used to be a throttle body issue on all cars anyway.

  16. You know this is a direct injection engine, right?
