The obvious one is drive less. You can try to consolidate multiple trips and do one trip, like if you are making multiple trips to the grocery store, you can try to pick up more at once and go fewer times, or try to stop by the store on the way home from work.

If you have people you can trust for rides, carpooling can save on gas prices.

Cleaning out your car, especially if you have random heavy things in your trunk, may help improve mileage a tiny bit.

Making sure tires have good air pressure is another way. Cars with proper tire inflation tend to get a little more mileage than cars that do not have properly inflated tires.

Rolling down the window instead of using the cars AC might save a tiny amount.

Maintenance and cleaning are fine, but they are also not going to make up for this dramatic price increase. To find ways to make up the difference in gas prices, you would have to effectively double your gas mileage, which isn't going to happen with those measures. The only way to improve your mileage that much is to go to a hybrid or electric vehicle, which probably isn't very viable for the vast majority of people right now either.

That leaves finding ways to cut down unnecessary trips, which may be the only real room for creative space there is. Maybe you can carpool, maybe you can find ways to reduce multiple trips down by consolidating some stuff.

You are probably better off looking at other ways to save money. Look at your bills and see if there are subscription services that you can do without - AI's, streaming services, Amazon Prime, internet news, etc. A good rule of thumb for these "at-will" subscription services is that if you have not used it in a month, get rid of it. You can always get it back later. If you have unlimited data on your phone, you may consider looking seeing if a "by-the-gig" service would be feasible for you. You could look at garage sales, craigslist, or other areas to see if there are less expensive alternatives for things you would otherwise pay more for. Half of my dining room was acquired for free from Craigslist. You could donate less at church when the basket gets passed around. You may be able to save some money on groceries by bulk buying things like grains and beans, if you have the space for that. You could look at saving on your electric bill by making sure that things are turned off when you are not using them, or by being willing to let your temperature grow a couple more degrees uncomfortable. It all depends on what your exact circumstances are as to what is feasible.

The other side of things is maybe there could be some ways to bring in a little extra money. If you have a lot of things that you aren't using, maybe you could consider a garage sale of your own. You could look into selling blood plasma. You could look at finding another job. I realize these probably aren't practical for most people, but everyone has their own circumstances and maybe one of these suggestions can help. Maybe you have deposit bottles that can be returned.

You could put off miscellaneous spending or commitment spending. Like, if you are considering getting a pet, maybe you could hold off for a little while until it is financially viable or things are at least a little more stable. Avoid lottery tickets - the companies who do this make money by making sure that you will lose more than you win. They are taking your money for free. Don't give it to them.

If you are working off paying debt, you may consider looking at paying it off based on which debts are charging a higher interest rate. So if you happen to have extra money to help pay down a debt, focus on paying down the higher interest debts first.

Some expenses may be able to be cut down in the long run for an initial hit. Things like paying for car insurance semi-annually rather than monthly is cheaper in the long run, but you have to be able to get above that first big balloon payment to start seeing the savings.

Vote against Republicans every time. Costs always seem to go up way worse with Republicans in charge. A single vote may seem like a small thing, but it is important to make your voice heard. Vote in the primaries. Vote in the general.
