What Our Clients Say:

“I was extremely impressed with the results obtained after testing these products on our buses running a regular route between Esbjerg and Billund. After 12 months of testing, the result obtained could be calculated at an average fuel saving per vehicle of about 5.06%, which when converted to Danish Kroner, results in very significant annual savings for our company. “

“We now use Tec4’s products on all our long-haul buses and can only recommend that other companies do the same.”
