Fuels
As a diagnostics company, the testing of fuels is all about problem solving
The high price of fuel means that many people take a chance and buy cheap fuel without thinking about why this particular fuel is cheap. Fraud in the wake of high prices thus increases.
Our asset in these contexts is that we know which analyses to choose to report the cause of an error/problem. In this way, we find out exactly what is required for the fault to be corrected.
VPdiagnose has the right resources and knowledge to help with these and thus costs can be reduced both in the short and long term.
