Case Study: BMW 520d X Drive 

A Six-Month savings assessment on a brand-new BMW 520d X Drive by Stephen Bamford (Retired Director of The SulNOx Group Plc).

Over the past six months, I have done a savings assessment on my new car and the numbers are incorporated with photographs from the car’s computer; December 2020 to March 2021  without the ElimiNOX Eco™ Fuel Conditioner and April to June 2021 with the fuel treated at 1 part per 2000 parts of diesel. 

  • The vehicle used for the savings assessment : BMW 520d X Drive 
  • After three months of general driving, the mpg shows 38.5 on Shell Standard Diesel but with no ElimiNOX Eco™ Fuel Conditioner added. 
  • After six weeks of using the ElimiNOX Eco™ Fuel Conditioner (late April). The reading is now showing 42.5mpg. 
  • The final reading at the end of June 2021 shows a reading of 43.7mpg. 

Costs and Savings Data 

On 31st March, I added 33mls of ElimiNOX Eco™ Fuel Conditioner  to a full tank using Standard Shell Diesel at 131p per litre =£86.46.

Assuming 8p per millilitre (full RRP price in UK) at 1 part per 2000 the cost was 33 X 8p =£2.64 – Hence a full tank incorporating ElimiNOX Eco™ Fuel Conditioner costs £89.10.

The increase in miles per gallon went from 38.5 to 43.7 = 13.5% (period end March 2021, to end June 2021)
The increase in cost with the ElimiNOX Eco™ Fuel Conditioner is £86.46 to £89.10 = 3.0%

The net financial savings are therefore 10.5%

38.5 mpg

After three months of general driving on Shell Standard Diesel but with no ElimiNOX Eco™ Fuel Conditioner added.

42.5 mpg

After six weeks of using the ElimiNOX Eco™ Fuel Conditioner (late April). 

43.7 mpg

The final reading at the end of June 2021 shows a further improvement

Driver observations and conclusions 

  • Since using the ElimiNOX Eco™ Fuel Conditioner, I found immediate responsiveness from the accelerator. This must be the “Lubricity Effect”. (Identified in the Bureau Veritas Certification) 
  • The engine at high speeds was totally silent and all I could hear was the wind noise. 
  • The ride was totally smooth and there were no vibrations at all. 

Owners of larger more expensive cars will tend to use Shell V8 rather than Shell Standard. For these drivers, the news is even better. Shell V8 is 146p per litre rather than 131p per litre so the financial savings are 10.3% before all the benefits shown above. (i.e. – a total of 20%+)

The addition of ElimiNOX Eco™ Fuel Conditioner offers the environmental reductions in toxic emissions “for free” – Shell V8 does not.

With results like this, why would I ever drive without the ElimiNOX Eco™ Fuel Conditioner in the future? The answer is quite simple – I will not!
