Having used DT5plus for more than 15 years and never had a problem. My Pajero NP returns 9/100 on average and runs as if it was new!!

Ive been using these products in my 99 Holden Rodeo for a while and absolutely no regrets. a highly recommended product range. it shifts and drives more like a sedan than a 4WD. superior power steering, shifting gears never got easier. Demonstrations have professional drivers stunned. I recommended it to a friend who experienced superior power in a Mack truck where normally the refrigeration unit kicked in and there went the power not any more he tells me, didn't even feel it start up

DT5, I have been using this product in all my diesel powered vehicles since 1983 and have had huge saving in engine and fuel system maintenance, over many thousands of kilometres.

I have used Pro-ma diesel treatment for over 20 years faithfully in farm equipment and highway tractors. With the huge fluctuation in temperatures between summer and winter we sometimes get caught with heavy summer fuel in the cold weather. But with the diesel treatment lowering the pour point we thankfully haven't been stranded on the road!

I have been using DT5 for the last several years. Since adding it to the fuel in 4 vehicles performance and fuel efficiency have increased dramatically.
