Graphic Demonstration of GTL Diesel Quality

The halfway stage of the Sasol Chevron GTL Challenge, over 6,500 kilometres, has provided the most graphic evidence so far of GTL diesel's clean fuel performance.

During a scheduled oil change in Nairobi, it became clear that, whilst the oil from the vehicles using traditional diesel had deteriorated and needed to be changed, the oil from ‘African Renaissance', the vehicle running on GTL diesel, was barely affected.

Expedition Leader Ian Myburgh said: “We're delighted. We are using a standard commercial motor oil and the implications for overall vehicle economy and reduced running costs are huge. The essential performance difference between GTL and the conventional diesel is related to the cleaner burning of the GTL diesel which leads to less soot formation in the combustion chamber. GTL diesel performs better due to its uniquely clean composition.”

Expedition Director Malcolm Wells, who was visiting the team in Nairobi, said: “We've given ourselves a new challenge and we're not going to change the oil on ‘African Renaissance' before we reach Qatar. On the basis of the evidence so far, it's still going to be the cleanest of all the vehicles despite having done double the distance. We've always told people GTL diesel is cleaner, now they can see for themselves.”

Toyota spokesman Roger Houghton said: “We've been behind the Sasol Chevron GTL Challenge since day one. From Toyota's perspective our vehicles and high quality GTL diesel are a natural partnership.”

BACKGROUND

THE SASOL CHEVRON GTL CHALLENGE

This is the toughest ever test for the latest and cleanest diesel fuel. The Challenge ,which aims to drive from the synthetic fuel plant at Sasolburg to the revolutionary new ORYX GTL plant in Qatar in less than 46 days, will demonstrate GTL diesel's ability to deliver higher performance with less emissions in one of the toughest motoring environments in the world. One of five vehicles supplied by Toyota will run the whole distance on GTL diesel.

ABOUT GTL DIESEL

GTL diesel dovetails neatly into tighter environmental controls and increased diesel consumption in many parts of the world. GTL diesel has a sulphur content of less than 5 parts per million and with a cetane rating of 70 plus compared to the 50/52 of standard diesel fuel, it provides superior performance and reduced emissions. The world has abundant natural gas resources, and GTL offers gas-producing countries a way to commercialize their resources whilst meeting a growing need for clean transportation fuels.

ABOUT THE ORYX GTL PLANT AND OTHER GTL PROJECTS

A joint venture between the state-owned petroleum company Qatar Petroleum (51%) and Sasol (49%), ORYX GTL in Qatar is the first low-temperature Fischer-Tropsch GTL plant outside South Africa dedicated to the production of new generation GTL diesel and the world's first commercial GTL facility to be financed by the international money markets. The plant will use Sasol's proprietary Fischer-Tropsch technology and London-based Sasol Chevron will market the high-quality, environmentally-friendly GTL diesel later this year. The ORYX GTL plant will convert gas from the North Field in the Gulf into 34,000 bpd of liquid hydrocarbons (mainly GTL diesel). In conjunction with Sasol Chevron and Qatar Petroleum, the intention is to increase the plant's capacity to more than 100,000 bpd. Also under construction is the Escravos GTL (EGTL) plant in Nigeria, owned by the Nigerian National Petroleum Corporation (NNPC) and Chevron Nigeria Limited (CNL) and supported by Sasol and Sasol Chevron.
