An online technical discussion forum for people working with diesel engines is largely credited for a 500% increase in 'hits' over the past year from marine diesel engine users and others now accessing Diesel-Talk, within the Glasgow-based website www.DieselEngineTrader. com The website has been up and running for two years but the introduction of Diesel-Talk last year has prompted the surge in site traffic. The site aims to help those within the industry solve their technical problems, whether coolant in the oil, excessive small end wear, erratic idling, overheating or whatever else.
