US cars for years are detuned vs Euro cars. Why? Perhaps the fuel.
If no one in the UK is burning 1 qt / 1000 miles, why is that? Fuel is a possible answer.
Ethanol is not an impurity or a reducer of "quality". It has some undesirable qualities and exists in fuel more for political reasons than practical ones. How does this contribute to oil consumption?
US fuel brands distinguish themselves with different detergent blends. I occasionally run fuel injector cleaner through a tank of gas. I have never perceived a before/after difference. How does this contribute to oil consumption?
Your comparison of octane ratings is as useful as a comparison of our gallons, and your assertion is completely false. They are different measurement methods. U.S. cars specify octane requirements calculated with the same method as the octane reported on pumps. If a U.S. pump says 87, it's RON 87, not (R+M)/2. Period. How does this contribute to oil consumption?
Yes, U.S. engines are de-tuned vs. EUR counterparts to address the lower octane of U.S. fuel. How does this contribute to oil consumption?
Your final statement has ZERO credibility. You have a general bias that you're applying to a specific. If the general bias is true, it should be generally true.
If U.S. "low quality" gas is contributing to 2012 Insight oil consumption, then why isn't "low quality" gas contributing to oil consumption of multiple U.S. models to a comparable degree?
I have owned 17 U.S. spec cars burning the cheapest U.S. gas I can find at any given time. These have ranged from Ford 460cu-in V8s down to Insight 1.0L with Honda, Chevy, Pontiac, Oldsmobile and Toyotas in between. Never had an oil consumption problem.
You have a misplaced bias that U.S. fuel is "low quality," and you are extrapolating that bias to explain a phenomenon. It is different than EUR spec fuel and in some ways inferior in some parameters, but again, it is not "low quality". I think it's safe to say that if 24% of the world's cars are running on low quality gas, and it contributed to oil consumption, there would be a LOT of oil consumption across a lot of models from different manufacturers.
IF U.S. fuel is contributing to rampant oil consumption in a particular model while the vast majority of other models/makes are NOT experiencing rampant oil consumption, what is the more likely cause? The gas or the design/manufacturing process.
You just presented information that Honda has mucked about with things and reverted to old designs... yet fuel is the problem?
