Aftermarket's Editor Impressed by Forte

The March 2013 issue of the Aftermarket magazine features an article about the visit of Aftermarket's editor to a Technical Training Day at Forté headquarters.

Our technical team carried out a number of checks and tests on the test vehicle, provided by Aftermarket's editor, Greg Whitaker. Then a demonstration was given to show the benefits gained by flushing the engine's oil system with Advanced Formula Motor Flush.

The magazine issue can be viewed online here. Please turn to page 56 of 60 for the full article, entitled "Oil be blowed".

Lack of power and engine management light on, fault code stored for turbo maximum boost limit exceeded, suspect fault due to sticking variable vanes on turbo.

The fault was cured by adding 2 x Diesel Turbo Cleaner and Advanced Formula Diesel Treatment into the fuel tank and carrying out a 15-20 mile road test the fault was cured and lack of power restored.

Thanks to Dave at Trinity Diesels in Salford, Manchester.
