Saw a dollar yesterday
But the wind blew it away
(As the following post demonstrates, 2 or 3 lines would never let a dollar bill blow away!)

Games like Sudoku and Wordle may be entertaining, but they don’t help a lick when it comes to saving money at the gas pump.
If you want to have more fun than a barrel of monkeys and save beaucoup dolares at the same time, you need to download the free Marathon Petroleum app – it turns a trip to the gas station into an enjoyable and challenging game of skill.
I’m assuming, of course, that you live in an area where Marathon gas is sold. Fortunately, there are Marathon stations in the overwhelming majority of states. (The ones that don’t have them – like Arkansas and Vermont – are states you don’t want to live in anyway.)

I recently returned from a group bike trip in upstate New York and needed to fill my car up. So I headed to the Marathon station that’s closest to the 2 or 3 Lines World Headquarters building, which usually has the best prices in the area.
A gallon of Marathon 87-octane regular currently costs $3.619. Marathon’s 89-octane midgrade gas – which they call “Marathon Plus” – is going for $3.899 a gallon, while 93-octane premium is priced at $4.299.

Most gas stations have only two storage tanks – one that contains the lowest octane gasoline that is offered for sale (usually 87) and one that’s full of their highest octane fuel (usually 93). If the station sells an 89-octane midgrade gas – which most stations do – it simply mixes two parts of its 87-octane gas with one part of 93-octane gas. (If you add 87 + 87 + 93 and divide the sum by 3, you get 89.)
You can do the same thing yourself. Let’s say your car’s manufacturer recommends 89-octane fuel, and you need 12 gallons of gas to fill the tank. You simply pump eight gallons of the 87 and then pump four gallons of the 93 – which gets you the same result as pumping 12 gallons of the 89-octane midgrade.
Why would anyone do that instead of just filling up with the midgrade? Because it usually saves money.
Today it would have cost me $46.79 to put 12 gallons of Marathon Plus into my car. But eight gallons of regular plus four gallons of premium cost only $46.15 – a savings of 64 cents.
Marathon’s midgrade is usually more fairly priced than the 89-octane fuel at other stations. (If I had gone to my local Exxon or Shell station today, my savings would probably have been two or even three times as much.) So I often don’t bother mixing my own midgrade gas when I go to a Marathon station, choosing to spend a little more money in order to save time – I am a very busy man, after all. I’m also very old – so my time is valuable!
Today, mixing my own resulted in my saving a lot more than 64 cents – thanks to the Marathon app.

I’m a member of the Marathon Rewards program, so I get five cents off every gallon of Marathon gas I pump. But because I have the Marathon app, I get text notifications about other special deals almost every day.

For example, Marathon is currently offering an additional five-cents-per-gallon discount on premium fuel. If I had pumped just midgrade today, I would have gotten the usual nickel-off-per-gallon discount. But by mixing my own 89 octane fuel, I qualified for an additional five cents off each of the four gallons of premium I purchased – ratcheting up my total discount from 60 cents to 80 cents. (Which meant I actually saved 84 cents – not just 64 cents – by not simply filling up with midgrade.)
In addition, I got a text earlier this week offering an extra five-cents-per-gallon discount if I filled up anytime during the July 4th weekend. That means I earned an additional 60 cents off – boosting my discount from 84 cents to $1.44.
But wait – there’s more!
If you fill up any time in July, you get an extra two-cents-a-gallon discount if you fill up a second time before the end of the month. So if I buy ten gallons next week, I’ll pocket another 20 cents. (Marathon adds another two cents to your savings each time you fill up in July – so the second fillup saves me four cents a gallon on my third fillip, a third fillup saves me six cents a gallon on a fourth fillup, and so on.)
On top of that, Marathon is offering $3 in rewards to anyone who fills up 15 times before the end of 2026. I’ll easily hit that number, so that three bucks is money in the bank for ol’ 2 or 3 lines.

Last but not least, I used my Discover card to purchase gas today.
You routinely get a one per cent rebate on all your purchases using the Discover card. But each quarter, Discover offers a five per cent rebate on specific purchase categories.
For example, in the first calendar quarter of this year – January 1 through March 31 – you got five per cent back if you paid for your groceries with a Discover card.
In the second quarter, restaurant purchases earned a five per cent rebate.
And in the current quarter – which began on July 1 – you get five per cent back when you use your Discover card at the gas station.

Let’s review the bidding.
1. If I had simply purchased 12 gallons of 89-octane gas today, it would have cost me $46.79.
2. By instead mixing 87-octane regular and 93-octane premium in a 2:1 ratio, I saved 64 cents.
3. By being a member of the Marathon Rewards program, I earn five cents a gallon on all my purchases – which means I saved an additional 60 cents by buying 12 gallons of gas today.
4. By taking advantage of the special discount on July purchases of premium fuel, I earned another 20 cents.
5. By taking advantage of the special discount on all purchases over the July 4 weekend, I earned another 60 cents.
6. By taking advantage of the bonus two-cents-per-gallon discount for all July purchases, I earned another 24 cents.
Put it all together and what do you get? I reduced the per-gallon price of the 89-octane gas I bought today from $3.899 to $3.709.
By using my Discover card to buy gas today, I reduced that per-gallon cost to $3.524.
Which means I saved $4.50 on my 12-gallon purchase – that’s close to a ten per cent savings.

I want to end this post by asking three questions.
First, is my arithmetic correct?
Second, why do I go to such lengths simply to save a relatively insignificant amount of money on a tank of gas?
Third, why did I write this post? Did I really think my readers would find it useful or entertaining? Or did I write it for some other reason?
Feel free to respond to those questions by using the contact form on the 2 or 3 lines website.

You might think that I picked today’s featured song because Marathon Petroleum is headquartered in Houston. But you would be wrong.
The company originally known as Marathon Oil was headquartered for many years in Findlay, Ohio. (Don’t feel bad if you’ve never heard of it. I’d never heard of it either.)
U. S. Steel bought the company in 1981, and moved the corporate headquarters to Houston. But Marathon Oil’s refinery division – which was renamed Marathon Petroleum – remained in Findlay.

“Houston” – which was a hit for Dean Martin in 1965 – was written by Lee Hazlewood, who wrote Nancy Sinatra’s biggest solo hits (including “These Boots Are Made for Walkin’,” “How Does That Grab You, Darlin’,” and “Sugar Town.”)
Sinatra and Hazlewood also recorded a number of duets. The best-known of their collaborations is “Jackson,” but the most interesting of their duets is the wonderfully weird “Some Velvet Morning.”
I’ll have to feature “Some Velvet Morning” in a future 2 or 3 lines post. I kind of wish I had featured it today. Too late now!)
