resembles the 'printer cartridge' technique.
Does that mean we get to buy the car for 50 quid, and pay £1k per oil change?

- come on BBC get with the times.
- anyway seems like a solution to a problem that doesn't exist.
Changing the oil is probably the easiest and quickest job on a car, certainly easier than changing a headlight bulb and I don't think there are many garages still draining it out the sump plug, they all vacuum it out.
It seems to me Castrol just want to sell a system where a car can only use their oil in their specific-fit cartridge. Good luck with that.

I'd though that too. However having watched my cars serviced at a franchised dealer (Perrys in MK) and a 'fast fit' (In and Out Northampton) both drained via the sump plug.

Took me 3 minutes.

My company done the consultancy work for this oil system.
I wasn't involved with the project but I did chat to the guys involved. Very clever
We had an Aston Martin for three months. Ploughed loads of miles on it.
Our development system looked very similar but was a round tube type system that you would turn then lift out.

Couple of advantages: reduced dumping of oil into watercourses as the container contents are recycled. The gadget also filters the oil, but I haven't seen whether it replaces full-flow filters or acts as a by-pass filter (better filtration) eliminating the filter cartridge currently used.
|
|
Is this similar to a dry sump system with the oil held in the plastic tank and circulated around the engine? If so there should be a scavenge pump in the sump to return the oil to the tank. If not the oil in the sump will not be changed when the tank is changed.

Typically carp bit of journalism, gives no idea of how it works. Does the cartridge live in there, and get changed from time to time, or is it only inserted for 90 seconds to exchange its contents with the engine? If so it is not like a printer cartridge that has to be swapped periodically.
If it lives there and gradually uses up the the new oil like a printer uses ink, then the engine is never actually getting a complete new fill.
But we don't know, so it was a waste of time making the video.

From the development system I saw, its the complete oil system including filter and all 5 litres of oil.
An electric pump will prime or empty the oil from the engine.
So in 90 seconds the whole lot can be lifted out / exchanged for a new oil box that has the new filter and oil.
In the 90's when I was in Germany, they had quick change oil garages that had a vacum system that sucked the oil out from where the dip stick goes on a car and put fresh oil in.
Of course it didn't change the oil filter but it was quick to change

So the car runs around with a cartridge in it, that is functioning as an oil filter, the old cartridge having been taken away full of the old oil? Does the oil live in the cartridge, or the sump?

the cartridge is the sump i think.

The cartridge is the sump. So the cars sump is no longer needed.
This tank system stores the oil and an electric pump will pump oil into or out of the engine.
I.e it contains all of the oil for the engine and its filter.
When it's lifted out and replaced , all of the oil and its filter is changed in one go

I assume then it has to scavenge all the oil back to the cartridge when the engine is turned off. And I guess therefore has to pump oil around the engine before it starts.
|
I think it does yes.
But when the lads at work were developing it. They just got in the car and turned the key to start it.
No waiting for oil to prime so I have no idea how it fully works
The Aston sounded lovely when fired up and driven off
We had a convertible DBS to work on
|
|
I saw a description somewhere that said it takes 90 seconds to pump the oil into the cartridge. I inferred from that it pumps the oil from the sump into the cartridge just before it's removed. The new cartridge would presumably then dump its contents into the sump.
|
Never had an oil and filter change yet where the oil wasn't drained off via the sump; when sufficient has been collected, the garages involved send it for recycling and presumably receive remuneration.
I wouldn't use any outlet that merely sucked engine oil out and then replaced it with new oil.....
|
|
A lot of diyers do it, theres a pela pump to suck out the oil. Not sure many have had too many problems.
|
>> I wouldn't use any outlet that merely sucked engine oil out and then replaced it

Maybe a problem for the future ? IIRC some makes no longer have a drain plug.
IIRC many small boats with inboard engines have the oil sucked out.
|

Nor me. I checked with In and Out before taking the car there. Perrys I'd seen previously. They have a tank on wheels with a very wide funnel in the top into which the oil is drained.

With any oil change there's a small amount of old oil left in the galleries no matter how long you leave it to drain. Probably not enough to do any damage but enough to muck the oil up quicker.
With a dry sump system (much more common on motorbikes) you can near as dammit eliminate this by doing what Harley owners refer to as a "four quart" oil change. To achieve this, you drain the oil tank, remove the filter; leave it for few minutes of course, then refit the tank drain plug, fill the tank, and before refitting the filter, crank the engine over until clean oil comes through the filter housing. Bit messy, and not perhaps environmentally friendly, but you are at least sure that there's less crap remaining in the system. I do it as a matter of course on the first oil change after any internal work's been done.

>>I saw a description somewhere that said it takes 90 seconds to pump the oil into the cartridge.
Here it is: tinyurl.com/novj6u4
" Along with the oil, the pod contains electronics that monitor flow, usage and quality. For example, it delivers less oil when the engine is cold, to ensure optimum performance and lower emissions. A small pump between the cell and the engine manages this flow rate. It also serves to suck up all the engine oil and deposit in the pod when you want to do an oil change. Which is why an oil change takes 90 seconds, not just the few seconds needed to lift out the old cartridge and whack in a new one."
|

Not sure I believe the 600 litres per minute flow rate. Maybe they make big'uns and little'uns.
|
"600 litres per minute"
10 litres/second is going some!
|
"We had an Aston Martin for three months"
A Vauxhall Astra wouldn't have done, then..? :-)
|
Do those Aston Martin V8 and 12s really only take 5 litres of oil ?
It looks perfect for a 1.0 Focus, plenty of space under the bonnet for the oil reservoir.
|
"resembles the 'printer cartridge' technique."
There will soon be 5 litre oil 'refills' available on Ebay, with a special 'filter cartridge' sold separately...
|
I once changed the oil on my A35 by turning it onto its roof outside Nottingham Council House.
Cost me a fine and points!

Zero tried to do that with his Renault! IIRC, it wasn't a complete success.
|

But Roger managed it without the assistance of a double-decker...
|
|
the goona stayed upright. Albiet bent.
|
|
Was yours a double-decker then Zero? For some reason I thought it was a single.

Or having discovered that the refilled cartidges don't work very well, you stock up on discounted genuine ones.
Then they change the specification so yours won't fit.
