Why cars need oil changes

[wurlycorner]

The trick is to make sure you have leaks.

This is so that your top ups over the oil change interval equal the volume of a full change, saving you having to actually change the whole lot in one sitting. Think of it like you're performing micro-changes, constantly refreshing your lubricant to ensure a consistent quality level rather than an exponentially degrading one.

It saves you time, money and energy. Only a fool would argue against this logic.

It has the added benefit of free rust treating the underneath of your car as you go, too (that's what I always said about my CXs, anyway )

Shocking - absolutely shocking. People shouldn't be allowed to own a car if they let this happen

The trick is to make sure you have leaks.

And to make sure that the exit holes are large enough to let out the tiny metal filings that accumulate from time to time.

I knew a black cab driver who used to brush his old oil on the chassis of the cab as a rustproofer
