Texasmark1 Think about why we would buy higher octane fuel. It is to deter knock in higher compression engines. The air out west is less dense so less air is pulled into the cylinder on each cycle. Less air means less fuel and the compression will be lower when the pistion is at TDC. This deters knock by it self so we can now cut the fuel octane. This is why you feel your truck runs like crap out there. It is drawing in less air leading to less compression leading to reduced power.
The problem comes in when a carbureted car comes back east with west coast fuel. We are now putting in more air leading to higher compression with less octane fuel. This can cause knock and could damage the engine if run for long periods like that.
Another problem comes with turbocharged vehicles out west. They are craming air into the cylinders but even with their best gas the motor can never see full power because of the lower octane fuel.
