The cost of Engine Oil – Professor Rob’s wise words

Engine oil - we all have to use it but who can say which type is best for a car. In the current economic climate you may think that cheaper oil is a good option but the truth is that splashing out a little more on motor oil is actually a good thing as the life of an engine can be affected by the quality of the oil used. There is a reason why certain oils in the market are cheaper and quite simply it’s because they aren’t as good. There are two basic types of oil - The first being high quality based oil with fewer additives - the more costly choice; and secondly, poorer quality based oil with lots of additives that are considerably cheaper. Both types meet spec when new – but when exposed to a running engine and elements such as EGR, many additives dissolve away and then there is only one stable solution that keeps on working. Don’t scrimp on oil quality – it will shorten engine life!
