Why oil and filter change is needed

[stuss]

We are all different, and so. opinions differ.

Yes !

 

[stuss]

Yes !

My cars are 1989 and 2001 mitsubishis and in the newer one am using Mobil esp 5w-30 and 89 using 5w-30 and changed every year but no mad mileage up.

I disagree

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

 

[cokeaddict]

My daily crapbox said it wanted servicing the other week, so I serviced it by resetting the service light.

Now says the oil is 100% again, so job done for another 2 years :)

The oil does get thicker over time, due to use and dirt. I knew someone who bought a second hand Vauxhall Omega 2.6l from an American. He rang me due to that the car wouldn't start. Got there, tried to start the car and it wouldn't even turn over. Next thing I did was to check the oil and it was like in the video! That was the end of that motor! The intervals for changing the oil and filters etc. you can find in the car manual and yes it's important, it extends the lifespan of your motor. I change the oil and filter either once a year or every 6000mls, inbetween the car is 32yrs old an has 145000mls on the clock and still running without using oil!

Nah ill pass mate thanks.

No way my oil is staying in beyond 6000 miles. Following that interval ive a 2008 210bhp diesil enigine with 267000 miles thats been in our family since new still sweet. It's had a new turbo though.

As an industrial chemist with a lab with all manner of testing equipment available to me i can tell you the spec of 6000 mile oil is not even close to the spec of the same oil out of the same container new. With this information even with longlife oil i would not run to the 10000/12000 mile services recommended. God knows what your oil would be like at 35000 miles.

And Sir you are wise!
Diesel engines run far hotter than petrol engines. Oil thins super quickly add to the inlet manifold adding burnt fuel/oil mix back into the oil from your EGR .
It's a disaster waiting to happen if you do not keep your oil clean.
Biggest killers of turbos is dirty oil and foreign matter entering the system .

Tbh with you what manufacturers say and what is real world are many miles apart no pun intended.
Years ago we didn't have a nasty egr system which actually causes far more issues than the NOX it's meant to prevent.
Myself I just blank off the exhaust into manifold (keeps it clean) keep everything else as standard

One of reasons I stopped using diesel cars.
