An Independent Laboratory Analysis of Shell V-Power 93 vs Midgrade Gasolines
Good links. Thanks.
One think about the second link I'd like to say. Is the Test was done in RON (Research Octane Number) which is what Europe and other places around the world use. But here in North America we use AKI ( Anti Knock Index ). So the Shell V-power came out as being 98 RON octane which for our land is equivalent to 93 AKI Octane.
Reason why I say this is because folks who read that post will think Shell V-power test came out as 98 octane when it reality it came out to 93 which is what it's supposed to be.
And the other sample came from a car rental company's tank, and tested to be 87.5 RON octane which would be closer to 85 octane in Amerika.
