Shopping for Cheap Gas and Better Gas Mileage

In a previous post I wrote about 7 ways to save money at the gas pump and I’d like to add two more to the list!  My motto is ‘the more I can save on the things I need, the more I can spend on things I want’.  You know, like retirement and the kids college fund – so I’m constantly looking for the best prices and savings strategies since pennies add up into dollars really quickly.

Because I can get a whopping 10 cents off per gallon at Murphy USA when I pay with my Walmart credit card (or 5 cents/gal with other cards including Walmart gift cards in most areas) I usually try to plan my route so that I can swing by a Murphy station when I need to fill up.

I recently learned about Additech, a fuel additive that guarantees it will increase your gas mileage by up to 10% and is available at the pump at most Murphy USA gas stations.  There is an option on the display screen at the pump that allows you to choose whether you want Additech dispensed with your fuel, and you can select a small ($1.99), medium ($4.99) or large ($7.99) dose of the additive.  I selected the medium and it was super fast and easy since I was able to pay at the pump and it was dispensed by blending with the fuel while pumping the gas.

Fuel additives work by helping to reduce deposits in your vehicle’s fuel system that can make your engine run rough and reduce your gas mileage.  Cleaning out the deposits that build up over time improves your car’s performance and increases your gas mileage, in addition to reducing harmful emissions.

For a limited time when you buy Additech at a Murphy USA station you will also receive a free Red Strike energy drink.  I’m usually a little leery of energy drinks because I don’t do caffeine and if I ever ingest any I get a little jittery, but with five young kids I’m always in need of more energy.  I pored over the label and the main ‘energy’ ingredients are Taurine and B vitamins so I gave it a shot and I actually liked it very much.  It tasted a little like Sprite with a fruity tang to it and it definitely increased my energy level, but thankfully without any jitters.  Because the large 16 oz can said it contained two servings I only drank half on the first day, saved the rest for the next day and was thrilled to get two days of extra energy out of the one drink.

  1. We always get our gas at Murphy USA so I see the additech stuff constantly. I have never pumped it before but I might do it next time. Will you write a follow up with any positive changes in gas mileage? (added by Mobile using Mippin)

  2. I’ve never tried Additech but it sounds like a great product!
