What are our customers saying?

"I just wanted to email and thank you and your mechanics for taking such good care of us and our Excursion. We were the ones that had a cam sensor go out on I-84 and you gave us directions from Winco. You got us right in, and we were able to make it up to Wenatchee, WA and back to Eugene without any further problems."

"I wish you had a shop here in Eugene."
Thanks again,

Eric Clark, Pres.
The Embossery Inc.
"She said they would refer this service center to anyone who owns a Volkswagen diesel. The customer said that the service center does a good job. The customer also said that she wishes they still owned their previous vehicle so they can keep going to this shop."

Question: What are the new Low Sulfur Diesel fuel changes I keep hearing about?

From: STANADYNE NEWS LINE – May 8, 2006
Re: Ultra Low Sulfur Diesel fuel (ULSD). New Line of Diesel Fuel Additives Stanadyne is about to launch a new line of diesel fuel additives to meet the requirements of Ultra Low Sulfur Diesel fuel (ULSD).This new fuel specification – the first major change in diesel fuel specifications in North America since “Low Sulfur Diesel” was mandated in 1993 – is driven by emissions legislation that limits the sulfur content of diesel fuel to only 15ppm (parts per million). This is a 97% reduction from the current maximum level of 500ppm sulfur which was introduced nearly 13 years ago. The new ULSD fuel specification is legally required for all on road diesel by October 15th 2006 in the USA. Off-road diesel will follow almost immediately. The main reason for this change in sulfur content is to reduce the level of harmful emissions from diesel engines. Sulfur in diesel fuel can cause sulfuric acid in the exhaust – leading to pollution of the atmosphere, corrosion of exhaust parts etc. Ultra low sulfur fuel is necessary to enable the use of new efficient and clean burning diesel engines. These engines run quieter, cleaner (smoke will also be reduced) and more efficiently. But the introduction of ULSD (sometimes also referred to as S15) is expected to affect diesel fuel injection systems on engines in much the same way as the introduction of “Low Sulfur Diesel” did in 1993/94, although probably not quite as severely. The biggest impact of ULSD is expected to be accelerated wear of highly sensitive fuel system components. In order to make ULSD, refineries use a process called severe hydro-treating. This process removes the sulfur, but also removes the natural lubricating properties of diesel fuel – which many fuel injection systems rely on to lubricate the pumps and injectors. In order to restore this lost lubricity, many diesel operators use fuel additives to help protect their sensitive systems and improve overall performance.
