Fuel Savings

Updated 12-12-07 (using $3.00 per gallon fuel cost as a comparison)

A vehicle averaging 30 MPG (miles per gallon) and sees an increase to 31.5 average MPG, increased their MPG by 5% (individual increases in mileage will vary, but for this example we will use a lower figure). This will mean a fuel savings of $71.43 for every 15,000 miles of driving at $3.00 per gallon fuel cost. The following chart will give 5% fuel savings at $3.00 per gallon fuel cost. For a 10% increase double the amount, 15% triple the amount etc.

5% fuel savings at $3.00 per gallon every . . .
MPG 15,000 miles 25,00 miles
40 $ 53.57 $ 89.29
35 $ 61.23 $102.04
30 $ 71.43 $119.05
25 $ 85.71 $142.85
20 $107.14 $178.57
15 $142.86 $238.10
10 $214.29 $357.14
5 $428.57 $714.28

As you can see by the chart, fuel savings adds up, even at 5%. Imagine a vehicle that increases its average from 10 to 11 MPG. That doesn't seem like much, but it's a full 10% saving $428.58 every 15,000 miles of driving at $3.00 per gallon!


Now let us compare costs . . .

Cost of Discount Store Motor Oil
A car averaging 40 MPG, really good mileage, that only drives 15,000 miles per year using petroleum motor oil and changing oil every 3,000 miles will have 5 oil changes per year. At every oil change, 4 quarts of cheap motor oil at $ .89 per quart and one $1.99 cheap oil filter (and I do mean cheap) adds up as follows . . .

$ .89 per quart X4 quarts needed =$3.56 total motor oil +$1.99 cheap oil filter =$5.55 total cost
$5.55 total cost of oil change X5 oil changes per year =$27.75 yearly cost of cheap oil/filter

AMSOIL oil change cost . . .
4 quarts of AMSOIL PCO (15,000 mile drain interval) @ $5.95 per quart plus one AMSOIL Ea oil filter adds up as follows . . .

$ 5.95 AMSOIL per quart X4 quarts/oil change =$23.80 total +$15.30 Ea oil filter =$39.10 total AMSOIL

Since this oil change and filter both are good for the full 15,000 mile period this is the only expense you have for oil changes. Assuming the possibility of adding 2 quarts of oil during the 15,000 miles you would have a total expense as follows . . .

$39.50 original oil change +$11.90 2 quarts of AMSOIL (possibly added during the 15,000 miles of driving) =$51.40 total @ 15,000 miles of driving using AMSOIL

Deduct from this the very conservative 5% estimate of fuel savings from our chart and you get the real yearly cost of using AMSOIL

$51.40 yearly cost AMSOIL -$53.57 fuel saved (from chart) =+$2.17 actual yearly cost of AMSOIL (This shows that you saved $2.17 more on fuel than the purchase price of the AMSOIL and Ea Filter)

AMSOIL cost compared to Discount Store Motor Oil
Now we deduct this from the yearly cost of the cheap bargain oil to see the savings using AMSOIL

$27.75 yearly cost cheap oil/filters -+$2.17 yearly cost using AMSOIL (Once again, the cost of using AMSOIL is a positive figure because the fuel savings came out to $2.17 above the cost of the AMSOIL/Ea Oil Filter) =$29.92 savings using AMSOIL

This was a very conservative comparison between AMSOIL and petroleum using a very high MPG vehicle realizing only a 5% increase in mileage compared to the cost of very budget motor oil and filter.


More realistic . . .

Average Car driven daily with regular oil changes at a Quick Oil Change Center
Driving 25,000 miles per year, at 20 MPG, with oil changes every 3,000 miles would mean more than 8 oil changes per year. Taking an average lube center sale price of $14.99 per oil change . . .

$14.99 cost per oil change X8 oil changes per year =$119.92 total yearly cost lube center

Compare to AMSOIL synthetic 5w-30, 10w-30, or 10w-40 25,000 mile motor oils . . .

$7.40 per quart AMSOIL X5 quarts per oil change =$37.00 oil total +$15.95 Ea oil filter =$52.95 total AMSOIL oil change

Since this oil change and Ea Filter are designed to be used for the entire 25,000 miles or one year our total expenses if we assume adding 3 quarts of oil during this time . . .

+$22.20 3 quarts AMSOIL added during the 25,000 miles +$52.95 cost initial AMSOIL oil change =$75.15 total yearly cost of AMSOIL

AMSOIL costs compared to Quick Oil Change Center
Subtract the yearly cost of the Quick Oil Change Center sale price from the yearly cost of AMSOIL. . .

$119.92 yearly lube center sale cost -$75.15 yearly cost of AMSOIL =$44.77 total yearly savings AMSOIL

But wait, what about fuel savings? Take 5% fuel savings of our 20 MPG . . .

$178.57 yearly fuel savings using AMSOIL +$44.77 oil savings AMSOIL =$223.34 actual yearly savings using AMSOIL

This was a more realistic comparison using a daily driven car getting fairly decent fuel mileage. The figures still favored AMSOIL Logo overwhelmingly. A vehicle averaging less than 20 MPG may be more typical and would see even better savings.


Really hard driven vehicles save even more . . .

A vehicle averaging 15 MPG and driven 35,000 miles per year, changing oil every 3,000 miles, would have at least 11 oil changes per year. Spending $20.00 per oil change at a lube center . . .

$20.00 lube center price X11 oil changes per year =$220.00 yearly lube center cost

Compare this to AMSOIL Logo Signature Series 2000 35,000 mile synthetic motor oil . . .

$9.95 cost per quart X6 quarts per oil change =$59.70 total oil cost +$16.65 Ea oil filter =$76.35 total AMSOIL oil change

At 17,500 miles, one filter change plus one quart of oil lost in old filter plus 3 more quarts possibly added during the full 35,000 miles . . .

$16.65 Ea filter/17,500 miles +$39.80 4 quarts of AMSOIL (one quart with the filter change @17,500 miles/3 quarts added during the 35,000 mile period) +$76.35 cost of initial oil change =$132.80 total yearly cost AMSOIL

AMSOIL costs compared to yearly Lube Center
Now deduct the yearly cost of yearly Lube Center oil changes from AMSOIL yearly cost . . .

$220.00 yearly cost lube center -$132.80 yearly cost AMSOIL =$87.20 savings AMSOIL

But wait, what about fuel savings? This vehicle was averaging 15 MPG prior to AMSOIL Logo and with a 5% increase in mileage now gets 15.75 average MPG. That's a yearly fuel savings of $333.33 at $3.00 per gallon fuel cost!

$333.33 yearly fuel savings AMSOIL +$87.20 yearly oil savings AMSOIL =$420.53 yearly total savings AMSOIL

The cost Benefits of using AMSOIL are easy to see. Additional benefits would include performance differences not mentioned in the above examples such as reduced engine wear, easier engine cranking, and lower temperatures under high heat conditions. Using a better motor oil is a cost effective option open to everyone. But only people who compare costs and care to use a better lubricant will benefit. How about you? Try one oil change. You'll be impressed!


AMSOIL Ea Oil Filters are designed for the filtration of synthetic lubricants. AMSOIL also makes a special By-Pass oil filter which, when used with AMSOIL synthetic motor oils, will make oil changes unnecessary! Through lube analysis you can be certain of the cleanliness of your oil is and the condition of your engine. It's state of the art engine protection.

The AMSOIL Ea air filter flows much more air than Fram and is comparable to K&N while filtering more dirt. It's cleanable and reusable making it quite possibly the last air filter your car will ever need! Less messy than K&N! No need to oil!
