“Castrol Vecton Fuel Saver gave a fantastic performance over an extended oil drain.”

Günter Südbeck is the Managing Director of Südbeck Nutzfahrzeuge GmbH, a MAN authorised truck workshop located in Germany. Mr. Südbeck always recognised his customers’ needs and their continuous efforts to reduce their cost of ownership. At the same time he was focused on delivering a high quality service using products that can perform effectively and can add value in the long term. So when Castrol proposed to trial Castrol Vecton Fuel Saver 5W-30 E6/E9 in one of his customer’s trucks he accepted.
‘’I operate Ludwig Südbeck Nutzfahrzeuge GmbH, which is a MAN authorised truck workshop and I often have to deal with customers who are under constant pressure to keep costs of oil low.

But I always want to offer an outstanding service using high quality products. When Castrol asked me if I was interested in testing Castrol Vecton Fuel Saver in the trucks of one of my fleet customers, I was really excited. I saw it as an opportunity to prove to my customers that I am using one of the most technologically advanced oils, which helps maximise the performance of their trucks and can offer long-term value to their business.

We tested Castrol Vecton Fuel Saver 5W-30 E6/E9 in three MAN Euro VI trucks¹ to the maximum drain of 100,000 km and in three MAN Euro V trucks² to the maximum drain of 120,000 km. During testing none of my customer’s trucks broke down.

Castrol took this one step further and analysed the oil samples every 20,000 km. This analysis showed fantastic performance of the oil such as minimal worn metal particles inside the oil, which means that the engine parts have only experienced a very minimal amount of wear during the whole oil drain. The viscosity remained stable. It didn’t get too thick, which could have increased fuel consumption, and it didn’t become thin, which may have caused wear inside the engine.

So now I have strong evidence to justify to my customers that I give a top class service using a lubricant which can help their trucks perform and can bring added value to their business.’’
