Business owners will know the cost of lost production, or downtime, when a business vehicle is off the road. There are big saving here, since component failures will become less frequent.

While many vehicle owners are often “do-it-yourself “ advocates, many still believe they can do no better than have the dealer service their vehicle and follow the manufacturer’s recommended service schedule. While this should produce acceptable results, by no means does it produce the “benchmark” for machinery life, operating efficiency and maintenance costs.

Surprisingly, the little extra things the vehicle owner can easily do, take little time and are inexpensive, but can result in saving $1000s in repairs and resale value. Importantly, please be sure to use only safe practices when working on any machinery, especially underneath your vehicle .. “If it’s not safe, either make it safe, or don’t do it.”


The environment will also benefit through more efficient use of resources. Image all the energy and resources that go into producing all the engines and transmissions of the world. By keeping them in service longer there are considerable environmental savings. Harmful engine emissions can be reduced and fuel efficiency improved, saving “greenhouse” effects and energy reserves. Did you know that for every tonne of diesel burnt, approx 3.4 tonnes of carbon dioxide (“greenhouse gas”) are produced?

We hope you enjoy our website, which will help you get the most out of your vehicle .. and help protect the environment by reducing air pollution by using FTC.
