Premium vs Regular Gasoline: Glaring Differences You May not Notice

reg_premiun_gasolineLately, with low gas prices I started consistently using premium gasoline (93 octane) from regular gasoline (87 octane).  Also, I deactivated the Green Fuel Booster.

The data captured shows some interesting graphs.

Here are the three variables that seemed to co-relate.

Torque – which simply is the pulling or pushing power of the engine.
Carbon emissions – in grams per kilometer.
Fuel efficiency – in Miles Per Gallon.

Using regular gasoline caused relatively bad carbon emissions of up to 250 grams per kilometer.
Using premium gasoline dropped carbon emissions by approximately 100 grams per kilometer.
at02

Using regular gasoline gives relatively low torque.
Using premium gasoline dramatically increases torque.
at03

A drop in carbon emissions has a negligible increase in fuel efficiency.
at04

An increase in torque also has a negligible increase in fuel efficiency.

If you are like me, who drives carefully like a parent with kids in the back seat, then, I do not need all that torque.

Simply  tapering the air intake after the MAF sensor will probably force the injectors to lower fuel use, therefore, increasing MPG.
