Ignorant Ways to Ruin Your Vehicle, Heard from a Mechanic's Perspective

Introduction

As a mechanic, I have unfortunately witnessed countless instances of owners mismanaging their vehicles in ways that lead to significant damage. These actions not only waste money but can also endanger lives. In this article, I will share some of the most ignorant ways I have seen individuals damage their vehicles, emphasizing the importance of proper vehicle maintenance and the dire consequences of ignoring professional advice.

1. Using Unfit Equipment – The Ex-Army Muir-Hill Shovel Incident

One of the earliest and most notorious examples I can recall occurred when a brand new Landrover 90 Defender, purchased by a nearby farm, was carelessly maneuvered using an ex-Army Muir-Hill Shovel. Far from being a tool, the Muir-Hill Shovel was unceremoniously used to move the vehicle sideways across the yard. Upon questioning, the farmer, with a thick Yorkshire accent, stated, “Nay lad, it’s just a tool like anything else!” Despite our advice, they continued to use the shovel, leading to significant damage to the vehicle.

2. Contaminated Oil and Engine Destruction

Next on the list is the infamous “GM bottle of death.” During a time when General Motors offered a buyback program, housing the landfill-dumped bottles of contaminated oil in the “clunkers” was a common practice. These bottles, often containing bleach, were accidentally ingested by unsuspecting owners, leading to seized engines and major repairs. One of my detail guys even joked about performing a “demos derby” behind the garage before disposing of these toxic bottles. This practice is a testament to the lengths some individuals go to ignore professional guidance.

3. Defending with a Vengeance – A Creative Abusing of Diesel Technology

One of the most troublesome incidents I encountered as a heavy truck mechanic was a case where a driver inadvertently pumped several gallons of Diesel Exhaust Fluid (DEF) into the fuel tank. DEF is meant to be injected into the exhaust to reduce NOx emissions. Mixing it in the fuel can cause significant harm to the fuel system, including the fuel tank, fuel injectors, and the engine itself. The cost to rectify this unintended mistake can range from $5,000 to $10,000, a stark reminder of the importance of adhering to proper procedure.

4. The Owner's Belligerent Obstructionism – A Turning Point in Green Technologies

In a separate incident, my sister called me over to inspect her car, complaining of unusual noises. Upon testing the engine and finding evidence of smoke and a burnt dipstick, it was clear that the engine had seized. When questioned about when the oil level was last checked, my sister replied, “Why would I check my oil? I just drive it.” This lack of basic maintenance is common but speaks volumes about people's ignorance toward proper car care.

5. The Belligerent Owner's Disaster – A Lesson in Aggressive Ignorance

A more alarming incident involves a truck driver who, in a fit of belligerence, attempted to bypass a mechanic's diagnosis and repair. The owner, a belligerent owner-operator, demanded immediate repairs and even suggested putting something in the engine to make it run. The mechanic, knowing the risks, refused, leading to a dramatic outcome. When the owner tried to fix the engine himself, the vehicle exploded, resulting in significant damage to the truck and the need for a complete rebuild. The owner faced severe consequences, including legal action and financial ruin.

Conclusion

The stories above highlight the importance of listening to experts and the potential consequences of not doing so. From a young man mishandling a vehicle to an owner pushing boundaries and endangering his truck further, these incidents underscore the wisdom of adhering to professional advice and conducting regular maintenance. Vehicle owners and operators must take responsibility for the proper care of their vehicles to prevent costly repairs and potential safety risks. Ignorance, unfortunately, is often not a blissful path but one fraught with danger and financial hardship.
