Accutrace S-10 Fuel Marker

Accutrace S10 –The Additive to End Diesel Laundering?

It had to happen. For years the Irish & UK Revenue Commissioners had tried different dyes; Solvent Yellow 124, Solvent Blue 19, Solvent Red 24 –all of them had one thing in common, chemicals of a similar nature and solid filters could be used to wash out the dyes making it difficult, if not impossible, for Customs & Excise to prosecute offenders.

So what did the various governments do? They set up a competition and invited suppliers of dyes to submit an additive that could be added to the Diesel Oil, be compatible with the fuel’s specification and be resistant to any attempts by the washers to remove it.Eventually, the Accutrace S10 molecular marker won the competition. Accutrace S10 is currently the champion of the Diesel world and is ready to take on all corners.

The Accutrace S10 molecule looks like a regular molecule of the Diesel family –similar to many of the molecules around it with one big difference; it has been put there artificially with an additive injection, and its presence in Road Diesel oil signals illegal product and invites prosecution.
Our Chemists in Independent Laboratory Ltd. use the latest GC Mass Spectrometer technology to detect Accutrace S10 in Diesel Oil. This instrument has the capability to focus on the primary constituent ions of Accutrace S10. Once detected, the concentration can be determined by examining the strength of the characteristic peak.
As Ireland’s leading Oil Laboratory, we are the first to be able to offer this service to oil suppliers and consumers in Ireland. If you’re concerned about the quality of your Diesel, have some suspicions about the bone fide of your suppliers or would like technical advice give us a call on 012401373/4.

Washed Diesel

Very few people in Ireland or Europe have not heard of the term “washed diesel”. It is a problem from the rocky west coast of Ireland to the flat plains of Russia. What does it mean? What are the dangers connected with it? And how can you protect yourself from collateral damage in the war between the washers and the Revenue.

Mainstream suppliers want this business to disappear. It’s the ultimate in unfair competition, where one party can sell the product for less than the other can buy it. And the present legislation makes it extremely difficult for a business to determine if a diesel oil has been washed. Here, at Independent Laboratory, we have encountered all the technical problems introduced by the changes in the diesel and Marked gas oil specifications, together with the impact of washed diesel on the engines, and we will try to give you an understanding of the technical hazards and risks involved.

Traditional Marked gas oil, a slightly heavier product than road diesel, has three dyes dissolved into it – Euromarker, Solvent Blue and now Accutrace S-10. Together they give the Marked gas oil that recognisable green colour. Washed diesel is Marked gas oil with the dyes removed. Acid extracts the Euromarker and various filter units extract the Solvent Blue. Both of the processes used have a serious risk for the quality of the oil – the acid content and the sediment from the filtration used to remove the Solvent blue dye can damages the injectors and the diesel engines. So how do legitimate businesses and the Customs recognise and detect these rogue products?

Recent changes in legislation have made the detection more difficult. For example, Traditional Marked gas oil has a sulphur concentration of approximately a few hundred parts per million (ppm) and this could be demonstrated by an X-Ray sulphur analysis. However, since January 2010, low level sulphur Marked gas oil was allowed onto the market, giving a comparable sulphur result to road diesel, thus weakening the impact of an important diagnostic tool. Traditional marked gas oil is still washed but more and more of the environmentally friendly low sulphur gas oil is now making its way onto the market.

What can the average honest businessman and customer do in this situation? The first thing he should do is operate practice of care. Does the price look right? Does it look too right? If it looks too good to be true, it has probably been through a process in a barn tucked away out of sight.

The chemists at Independent Laboratory have been providing an analysis service in this area for years. We analyse each sample with two distinct aims in mind: firstly, does the diesel oil meet the British and Irish standard specification in the quality tests; and secondly, will the Customs prosecute the client if they take a sample and have it analysed in the State Laboratory? The aim of our technical reports is to inform the client on the quality and legality of the oil in his vehicle.

The recent changes in oil, referred to earlier, have made it difficult to detect washed diesel, but the Customs still have it within their power to prosecute if they discover any trace of dye in the diesel. Thus it is technically possible for them to prosecute with even tiny amounts of marker dye present. The latter, probably with additional logistics and surveillance evidence, has still to be tested in court, but there is no doubt that it will happen. Also, new dyes, with claims from the manufacturer that they are irremovable, are being offered on the marketplace. But even if these are eventually accepted, there will be a delay before the legislation can catch up. Meantime, we urge our clients to be vigilant and we will keep them up to date on the latest technical developments.

What Causes Cars to Stop

A car pulls into a garage and fills up with petrol or diesel. The driver pays and starts driving down the road. There’s a funny noise around the engine. A squirrel is trapped inside and the car is travelling like a kangaroo. Eventually, the car limps into a service garage and an investigation begins. Continue reading
