Do Fuel Additives Fuel Pills Tabs Work to Increase Fuel Mileage?

Following is a usage test I did on a product Ruk Fuel Tabs. I have to admit I was skeptical but in the end the these fuel tabs did work for me. I did the tests on my 2007 Jeep Wrangler and 2007 Nissan Versa. I use both cars for mostly commuter duty. I travel about 60-80 miles each day to work with most of it the miles on the freeway. I did not change my driving habits or use any other gas savings techniques for this test.

Jeep Wrangler 2007 JK Sahara Model

Mileage when test started: 49,645
EPA Numbers: 18 MPG Combined 16.9 MPG as commonly tested
Tank Capacity: 21.6

I did a total of 10 fuel fill-ups, five with Ruk Fuel Tabs and five with no additive. Normally the vehicle is tested at 16.9 miles per gallon. With 85 octane fuel I was seeing an average of 17.58 miles per gallon. With the fuel tabs I saw an average of 19.25 miles per gallon. Below are the totals of the test results with using the fuel tabs and without using any additive. The cost of a 10 pack of the fuel tabs was $7.95 and I used two tabs per fill up. The dosing instructions required 1 fuel tab for every 16 gallons of fuel for best performance. After adding the pills I noticed a little more power, I was told that the first treatment might actually lower my gas mileage as it cleans out my system but I did not see that. Below are the results of the test.

With Ruk Fuel Tabs:

Average Miles Traveled per Tank: 375.40
Average Miles per Gallon: 19.25
Average MPG over 16.9MPG 12%
Average Miles over 16.9MPG 2.35
Total Savings Including the fuel tabs cost: $25.29

With No Additive:

Average Miles Traveled per Tank: 326.48
Average Miles per Gallon: 17.58
Average MPG lost from 19.25MPG -10%
Average Miles over 16.9MPG .68
Total Savings Lost by Not Using the fuel tabs $25.29

From the test results you can see that I averaged about 49 more miles per fill up that is about 2 more gallons per tank or $5.40 dollars saved per fill up. That is a nice savings. I averaged about 1.67 more miles per gallon using the fuel tabs. I got 2.35 more miles per gallon over the average tested mpg of 16.9 and finally I saved a total of $25.29 using the fuel tabs including what I paid for the use of the fuel tabs. That reduces my monthly fuel bill by almost 10%. In addition I am told I getting a cleaning running engine which helps lower emissions, more power, and longer lasting parts. I cannot test that so I am not sure if that works. This would give me an annual savings of $300.00 or more.

Nissan Versa 2007 Base Model

Mileage when test started: 73,663
EPA Numbers: 30 MPG Combined 28 MPG as commonly tested
Tank Capacity: 13.2

I did a total of 12 fuel fill-ups, seven with Ruk Fuel Tabs and five with no additive. Normally the vehicle is tested at 28 miles per gallon. With 85 octane fuel I was seeing an average of 29.25 miles per gallon. When the switch was made to winter gas I saw an average of 28.76 miles per gallon. With the fuel tabs I saw an average of 31.35 miles per gallon and this test was mostly done with winter gas blend which is not as effective with fuel additives. Below are the totals of the test results with using the fuel tabs and without using any additive. The cost of a 10 pack of the fuel tabs was $7.95 and I used one tab per fill up. The dosing instructions required 1 fuel tab for every 16 gallons of fuel for best performance.

With Ruk Fuel Tabs:

Average Miles Traveled per Tank: 339.52 Winter Gas
Average Miles per Gallon: 31.18
Average MPG over 28MPG 10%
Average Miles over 28MPG 3.19
Total Savings Including Fuel Tabs Cost $13.33

With No Additive:

Average Miles Traveled per Tank: 312.93 Winter Gas
Average Miles per Gallon: 29.25
Average MPG lost from 31.34MPG -7%
Average Miles over 28MPG 1.25
Total Savings Lost by Not Using Fuel Tabs $13.33

From the test results you can see that I averaged about 27 more miles per fill up (winter gas) that is about 1 more gallons per tank or $2.70 dollars saved per fill up. That is a nice savings. I averaged about 1.93 more miles per gallon using the fuel tabs. I got 3.19 more miles per gallon over the average tested mpg of 28 and finally I saved a total of $6.33 using the fuel tabs including what I paid for the use of the fuel tabs. That reduces my monthly fuel bill by almost 5%. In addition I am told I getting a cleaning running engine which helps lower emissions, more power, and longer lasting parts. I cannot test that so I am not sure if that works. This was much more than I expected since this was already a high fuel savings car. This would give me an annual savings over $75.00 or more. Since I did this test using winter gas I would expect better test results during the switch back to normal gas.

Overall I believe that this has worked to increase my fuel mileage. I will continue to run more tests and update this report as they become available.
