Problems with the wrong fuel system
Fuel contains lubricants which ensure the smooth working of fuel system components in a diesel powered engine.When you’re used to driving a petrol-powered car, and you’ve just swapped to a diesel powered car, that’s when the incorrect type of fuel is mistakenly put into the tank. Unleaded petrol does not have these same lubricants; consequently, if you try to run a diesel engine with unleaded fuel in the system, you’re not going to get very far before your vehicle breaks down. You are also risking damage to the fuel system components of the engine due to the lack of lubrication; this is more of a problem where unleaded petrol has been added to a decent amount of diesel, which has gone unnoticed by the driver. The vehicle engine will perform poorly and may end up breaking down hence costing you dearly.
This can, in turn, cost you the following problems
The obvious consequence, as anyone with the tiniest understanding of physics, will know, is a worn engine. But the results can go way beyond engine or gearbox wear and reduced engine life. Mechanical damage related to the poor choice of engine and gear oils can bring other unplanned costs and hassles.
Even if yours is a reliable-but-old 1990s oil-guzzler, skimping on quality lubricant to save cash may still prove a false economy when engine failure due to clogged breathers and filters, inadequate lubrication or damaged big-ends means having to buy another vehicle sooner than planned.
Engine oils and reduced fuel economy
With many manufacturers now specifying 5W-20 oils for increased fuel economy, there’s more scope for getting things wrong. Manufacturers’ and oil companies’ engineers spend millions formulating the perfect lubricant for different vehicles. You ignore their recommendations at your peril.
Possible invalidation of manufacturer’s warranty
The notion that producers’ warranties will be invalidated if you don’t use the brands of engine oils they suggest may not be correct. But failing to use their recommended oil specification is. Whether you use Texaco, Shell, Exxon or another make of automotive oils should be neither here nor there – but using a 10W-30 when the book says 0W-30, or using conventional oil when you should be choosing synthetic motor oils, could be asking for trouble.
Lost productivity and reputation
As car drivers, we’ve all experienced the hassle resulting from a mechanical failure – whether lubricant-related or not. It’s bad enough if the problem makes us late for work or necessitates a costly garage visit. But what if you’re a fleet operator running hundreds of vehicles. For your drivers, mechanical failures due to wrong fuel and engine oils could mean lost business, sullied company reputation, and other indirect costs. And then, of course, there’s the risk of lowered residuals when the vehicle is disposed of. Suddenly, skimping on motor oils over the years could reveal itself as a destitute business decision…
Lower residual values
The motor trade knows what it wants when it’s auction time, and that five-year-old executive express finally leaves fleet service. That’s when good maintenance can pay off with a higher auction price. And with today’s challenging economy, getting the best possible disposal price has never been more important.
