Your vehicle's tire pressure should be the same or slightly higher than that recommended by the vehicle manufacturer; a lower pressure will increase fuel consumption or say decrease the milage. To save cost on fuel, you have to regularly check and inflate tires of your vehicle to reach the proper air pressure.

And which gasoline is probably the best to use? (Leaded? Unleaded? ... it's been so long since I've been to a 'gas-stop' (I don't even remember what to CALL those!) that I don't remember) Do you save more if you buy higher quality (with slightly better mileage) or lower price (which might burn faster)?

They've got Regular, Plus & Premium (and some have Diesel) ... where am I remembering 'Leaded & Unleaded' from?

Hmm ... my etymology-source says "Regular" has applied to both 'Leaded' AND 'Unleaded' gasoline!

"Regular" is built on ancient words that mean "to Move in a Straight Line." - search-tags xRegular xIrregular xRegularize xRegularly

We use simple Petrol/ diesel vehicle, so ours is different then that, but I don't think premium is really better.

My husband always checks the tire's air pressure, especially before a long trip. If the air pressure is correct we can save some money on fuel.

This is a very good tip and definitely we need to check it before going out for a ride
