Well My '93 S10 has the 4.3L .
So my vehicle is paid for, insurance is less with all the safe driver discounts, and such, Hwy I get 25+ mpg [extended trips I get 30mpg], city I get 16 - 18 mpg. [ Geared for hwy].
Helps not having to make payments, and highter insurance.
Even so I watch / plan trips. 20 gal tank - I let it get to half and fill back up. My college is across the river ~ 20 mi one way. I take on-line classes when can. I have already had some semesters I never set foot on campus, except to get some paperdrill done or teach a clinic. [ I was teaching Professors, and teachers - LOL!]
Hopefully I can get classes on campus on the same day and save extra trips. I have two Cisco classes I have to be on campus for due to labs.
Oh...when I do something for someone, I accept cash only, or they can fill up my truck with their debit card. Sometimes I just get the use of the Corp credit card. [ I do as much as can off- paper ]
I am not a shopper - that said I use the Internet to order stuff and have shipped to door. I have even been busy with everything and call the Mom&Pop grocery and let them drop off groceries, I tip them off course - still saves me time and my gas.
When I have been sick or recovering from surgeries - Pharmacies make deliveries too. Mine only charges a $1 extra fee for this.

Got a classmate, decided she did not like the Buick she inherited from deceased Grandma. Sold the car to a family with first baby on the way. Paid cash for a older Toyota Camry, in great shape well taken car of. Gets better mileage, less insurance. Like me she shops online, has Pharmacy make the deliveries to her .
Unlike me she can do that head tilt and nod, loosen a button on blouse and the Pizza / Food delivery guys don't need a tip. They might stumble off the porch...
She came up with that tip for her married friends with daughters - let the teenage daughters answer the door in short shorts, and Tank tops for the Pizza guy...them tips add up fast "Dad" . LOL
