  Let us know what you think about this test in the comments section. If you have tested any 'racing' diesel fuels yourself we would love to know!

  The amusing thing about tests like this, is the data will be there in black and white, yet people will still be adamant that their choice is better for reasons.

  When will  people understand that Premium Diesel has never been about Performance gains. its all about keeping your engine in top condition. Ive ran my BMW 120d M Sport with 202,000 miles, ALWAYS used Shell V Power Diesel, Engine in prime condition, DPF not clogged once, Injectors are running clean and free.  With premium diesel its less about performance gains and far more about longevity of the mechanical parts with the use of detergents that are blended with the fuel.

  Your base fuel comes usually from the local refinery.  It makes sense logistically when you think about it.  In Southampton for example, the local refinery is the Exxon (Esso) refinery at Fawley.  So you will see Shell, Mobil, Total, ASDA, Tesco etc tankers rocking up to fuel up.  The drivers then add a particular additive package to the tank.  By the time the lorry has been around a couple of roundabouts on the A326 it is considered "mixed to perfection".  However the base fuel for them all is Esso. Only the additive package differentiates them.

  Would be interested to see how Costco "premium" diesel compares to other premium diesels. Also if you guys are able to hub dyno you could eliminate a few variables

  Used to build filling stations and was quite involved in the process of buying / selling fuel. I can tell you the condition of the forecourt is far more important than the brand. All fuel comes from the same refineries, the additives difffer. A poorly maintained forecourt is far more likely to lead to dodgy / contaminated fuel & cause issues than supermarket fuel. Supermarkets make very little profit on fuel. Their margins come from people visiting the shop before/ after they’ve filled up. Worth millions per year per store.

  I always thought that the higher price was because they had cleaning additives added, keeping injectors and fuel pumps clean and better lubricated etc, and coke deposits down in the engine, giving better fuel efficiency long term, great post, thanks for your hard work.

  I used premium diesel in the Subaru Forester. It helps not to build up Soot Accumulation in the DPF too quick, and the cleaning cycle is burns off faster.

  V power has additives to keep the injectors clean , not to improve power.

  I&apos;ve been running EHN-99 in my 1.9 DTH engine with a 190 PS remap for a year and the results on fuel consumption where night and day. <br>I&apos;ve owned my Vectra-C for 15 years and have measured fuel consumption many times over the years and it&apos;s been great for detection faults when they happen, like dragging calipers.<br>Prior to using the additive the car was averaging upto 56mpg on 66 mile work commutes 5 days a week on dual carriageway and some local driving. I was using Sainsbury&apos;s regular diesel. <br>Always get receipt and do the 4.54 division into gallons and divide into trip mileage.<br>Once I started using the EHN-99 additive the fuel consumption went up to 61 mpg with no change to driving. <br>On a longer 800 mile run over 1 day, the car achived 68mpg, which it had never done in 15 years. <br>Additionally, I&apos;ve used it in my VW 1.9 TDi PD Bora and saw an increase in local driving from 41 mpg to 45 mpg.<br>Based on 8,000 miles of driving last year, I&apos;m convinced on the extra mpg and the cost per tank is around 40p.
