First we need to go back in time, as engine
oil use to be very simple and easy to understand. Now engine oil and tolerances
within engines have become more refined.
Many years ago is was abnormal for engine oil be consumed during normal operating conditions. I can remember many years ago it was a standard that engine oil interval changes were between 8000 to 10000 kms.
So much has changed with motor vehicles today. It seems to be normal for your average car to have service intervals extended to between 15000 and 20000kms.
Now it seems normal or more to the point an engineering fault or failure where Car makers says its normal for engine to consume oil between services.
In my view the reason for the extended
service intervals are more for the reason of New Car market share. This marketing
tool to provide a cost reducing of motor vehicle servicing for fleet owners
will only be the fleet life of the first 100,000kms.
The problem is for the punter purchasing a secondhand vehicle with a potential engine failure and or potential oil leaks due to prolonged service intervals or maybe lack of service intervals, prior to vehicle disposal.
The following reasons for engine failure are the following;
1, Potential engine damage due to lack of oil at the correct level between service intervals.
2, Prolonged service intervals may cause oil to loose its protective properties this may cause long term or premature engine wear.
3, Using the wrong oil will definitely cause engine failure, oil is very critical as engines have become refined within engine component tolerances.
There is a big difference between a company fleet vehicle and a private owned vehicle in terms of motor vehicle value in the long term. The problem is that we are influenced into thinking that a passenger type vehicle is at its best from 0 to 100,000 kms. Is this because we are accepting that cars are made very cheap or that we have decided to agree with the prolonged serviced intervals and therefore devalue the market potential of the second largest investment of the average person within Australia.
