Calculate Your Annual Fuel Savings

Want to see the numbers? Use this tool to estimate your vehicle’s fuel efficiency and potential savings! Our Fuel Economy Calculator is built to give you quick estimates of your potential fuel savings by making the switch to Synthetic SN PLUS motor oils.

Just input your basic data like driving distance, fuel price, and your vehicle’s average MPG (or liters per 100 km if you prefer Canadian). Remember: Fuel economy is the distance traveled per unit of fuel—or simplified, Distance Driven / Fuel Used.

It really is that simple. If you’ve been sticking with the bare minimum conventional oil for your engine, it might save a few bucks now, sure. But for most driver’s, it doesn’t even take a year to make up the difference in fuel savings alone – and that doesn’t take long-term engine health into account at all.

It also tracks your gas mileage over time as you switch to AMSOIL and see the difference. You’ll see what we mean… just go on and give it a try.

Baseline Settings | Why does this calculator default to 1.7%?

The 1.7% default is chosen because it represents a minimal, conservative increase you can expect from using resource-conserving motor oils or after just the first treatment of a quality fuel injector cleaner.

While there is no specific MPG standard, our own testing (and that of AMSOIL) often shows a minimum improvement of 2.5% or better with our motor oils alone. In fact, it’s not uncommon for our customers to report 5% to 8% or better fuel economy increases from using our products.

When fuel injector cleaners are used in conjunction with these top-quality engine and transmission oils, results are often compounded, and an 8% increase can be a very reasonable estimate.

For this reason, we’ve deliberately chosen 1.7% as a safe, low-end estimate, but the calculator is designed to adjust up to 15%.

Using the calculator is only step one. If you want to spend less on the cost of fuel over time, there are some habits and choices that make a big impact:

• Use the lowest viscosity oil that’s suggested for your engine
• Switch to AMSOIL Full Synthetic SN PLUS Motor Oils
• Run AMSOIL PI Performance Improver for a quick win in the fuel economy game

Why give Petro Canada, Esso, Shell, or Chevron a bigger chunk of your paycheck than you need to? Some routine maintenance makes your gas money go farther, and that’s a fact. Stop wasting fuel and start putting AMSOIL’s performance to work for you.

Synthetic oils are engineered for precision. They maintain their viscosity better across a range of temperatures and driving conditions.

Think of the molecules in oil like marbles – yes, the little glass spheres from your childhood. When you have conventional oil, those molecules are like having a mix of small, medium, and large marbles together, and try rolling a flat surface on them.

Doesn’t go so smooth, does it?

But with synthetic oil, the molecules (or marbles) are all consistent sizes, more evenly distributing the force. Now things glide much easier overtop, reducing friction and providing a better barrier.

Whether you’re running errands with the AC on full blast or hitting the highway with a full gas tank, synthetics reduce drag in your engine. Less drag equals less fuel burned.

And because synthetics resist breakdown better than conventional oils, they last longer, too. That means more consistent fuel economy between oil changes.

In colder climates or during early morning starts, thicker oils take longer to circulate through your engine. Wasted fuel, inefficient combustion, and more internal resistance are all common.

Synthetic motor oils maintain better cold-flow properties, which helps your engine warm up faster and perform better from the start. The result? Better fuel economy and better mileage, even in chilly conditions.

Your fuel economy isn’t set in stone. It changes based on how you drive, what you carry, and even the weather. Here are the key factors that influence your gas mileage:

Driver Behavior
Speeding, harsh braking, rapid acceleration, and constant use of air conditioning all burn more gas. Adopting smoother driving habits can dramatically improve your vehicle’s fuel efficiency.

Vehicle Load
Heavy loads mean your engine has to work harder, especially when climbing hills or during city driving. Reduce weight to use less fuel.

Tire Conditions
Under-inflated tires or uneven tread can hurt rolling resistance. This increases the amount of fuel needed to maintain speed.

Ambient Temperature and Weather Conditions
Cold starts and windy conditions both impact efficiency for the worse. Your vehicle may use more fuel simply warming up or fighting a headwind.

Geographical Terrain
Hilly terrain or frequent elevation changes increase the energy (and fuel) needed to maintain speed.

Vehicle Maintenance
Dirty air filters, old spark plugs, and neglected oil changes will decrease fuel economy. Regular maintenance helps preserve the best gas mileage possible.

Use your current odometer reading, track how much gas you use per trip, and keep an eye on the trip calculator. This will give you a realistic baseline to measure future improvements.

Whether you’re planning a road trip, budgeting for commuting expenses, or comparing a compact car to an SUV, the Synthetic Lubricants Fuel Cost Calculator gives you real answers for simply using AMSOIL Synthetic SN PLUS OE (original equipment) motor oil.

A 1.7% improvement in fuel economy might not sound like much — but it’s just the beginning when you choose AMSOIL® and commit to lower fuel costs over the long haul.

The true reason customers consistently choose AMSOIL, even with its higher initial price, is that the savings and performance benefits quickly turn the purchase into a genuine investment in their vehicle’s efficiency and longevity.

From Percentage Gain to Dollar Savings
Our calculator defaults to a conservative $1.7% gain, but let’s look at the real-world impact that explains the higher cost:

As you can see, that $5% to $8% gain—which is commonly reported when combining our Signature Series motor oils, transmission fluids with our fuel injector cleaners—can generate over $100 to $160 per year in fuel savings alone. This quickly offsets the initial cost difference compared to conventional oil.

The Total Cost of Ownership Advantage

The ROI of AMSOIL is compounded by hidden savings that dramatically lower your vehicle’s total cost of ownership:

Lower Maintenance Costs: AMSOIL offers extended drain intervals, meaning you buy fewer filters and spend less on oil changes over time.

Reduced Repair Risk: Superior protection against friction and heat extends the life of critical engine components, insulating you from the risk of expensive, premature engine failure.

Maximum Resale Value: A well-protected engine often translates into a vehicle that commands a higher price when you sell or trade it in.

In short, AMSOIL is a premium product that provides premium returns. Customers buy it because the initial investment quickly pays for itself in gas savings and is reinforced by significant long-term maintenance protection. They buy it not because of what it is… they buy it for what it does.
