Why oil and filter change is needed

Decent car oil and filter change every 5k (6k max) or 12 months whichever comes first.

Daily runabout shitbox, doubt i'll ever bother to change the oil just keep topping it up when it starts to sound more rattly than usual.

With an attitude like that it will be sooner for the price of oil and filter could last much longer as fresh oil lubricates better than gunged up.

Decent car only gets proper fully synthetic (usually ester based) oil.

Runabout will get whatever I have in the garage, last topup was 10w60 oil left over from my old E46 M3, before that I think it had some 5w40 left over from an old Evo 6.

If I start to get low on left over fresh oil, I have about 25 litres of low mileage used fully synthetic oils I can chuck in it.

I don't want the daily runabout to last, hate the bloody thing.

But yes I know, i've built enough high performance engines over the years, hence why I said decent car, gets decent oil and regular changes.

The blomonge in the sump in the video is comedy gold....the clean, unstained oil filter shiny steel inside top gave the game away at the beginning.

Replies about changing oil every 6k miles or less always baffle me.....unless you've got a modified, rebuilt, highly strung engine then there little if any benefit to be had by changing the oil more frequently than manufacturers recommended service intervals, modern engines aren't what engines were 40 years ago, most modern engines will plod along quite happily well beyond recommended service intervals.....
Apart from a Ford 1.0 3cyl - they fail for fun even when serviced early

most manufacturer's these days believe there engine's can last 25k/24months per a service as the annual milage per a year is around 20k now for most people, but ive seen alot of vehicles come in for service with way less milage requiring a service, it all depends on driving style and journey type aswell, lots of short journeys will destroy the oil life faster and inturn req more servicing annually then alot more longer journeys would.

Well my tuppence worth I change mine every 5k and do gear oil every 50k reason it cleans out the dwarf and gunge the engine can then breathe, old oil breaks down naturally especially if your engine is a very high temperature engine like a diesel. This creates heaps of problems later down the line with seals bearing etc. Which can also cause problems with cat and dpf. If your engine cannot breathe properly it will in time find the weakest point and it will fail badly. I look at it this way I feed myself good food to keep my engine running tip-top, and have the same out look for my vehicles simples love it or lose it
