591639, Eco drivers forum should be under hypermilling and ecodriving not ecomod central.
Low oil will not increase gas mileage.
Hotter pugs will not warm your engine up faster.
low octane will not increase your gas mileage.
Any questions? Good, lets move on.
An engine blanket will keep your engine warmer. Has to be nonflammable type. I use fiberglass fabric. Engine warms up faster, since it is warmer to start with. Good for short trips. I use to drive home for lunch and and after 4 hours it still registered on the gauge.
Hot air intake will warm the engine up faster, Saturn gets to 220F intake air temp on the interstate.
I made a custom 205F thermostat for Saturn.I got them at Rock Auto, I bought several on clearance, for 80's GM car.
Plug in block heater will warm your engine up at home, but costs electricity.
Thinner oil will increase gas mileage, I use 0w20.
I use to gap the plugs larger, and jet it lean, but no need on modern engines with emission controls. This worked well for CVCC and Rotory engines.

Low oil - as on min on the dipstick - would not cause any harm. Not even in a hard corner - unless you drive a car that are 3 decades old.
Also again given that this is an eco forum, contamination in the oil would take alot longer time than with a regular driver. I rather change more frequently anyway.
Going one grade hotter plugs wouldn't change much if any, most engines are specified hotter during generation shifts anyway. Colder however can be a mess.
