Neighbours oil change

Cheers Dave. It's only around a gallon every six months that I would throw in it anyway , not a huge amount...

But they weighed a lot less than modern ones, perhaps?

Sanctimonious idiot. It came from the ground in the first place.

And they were mostly a lot slower.

Don't kid yourself.

And feeding rain forest growth.

I've got one of those drain cans with a drain tray that runs into a can. The can takes about 3 oil changes. I then take it to the tip.

But I've been getting lazy and feeling old the last few years and been getting the specialist who used to service the car for old owners to do it for me.

The car has been well serviced and still passes MOTs with 170k on it even though it looks a bit ropy so I must be doing something right.

Yes, but it's a red herring either way-- we're talking about one gallon every 6000 miles or more.

I guess that this is a windup, or are you seriously mad? Take the oil to your nearest re-cycling centre! No, im not green welly or anything like that, but the oil will seep down to the water bearing layers and spoil it. If a company poured oil down the drain, they would be fined thusands ££££.

One of my friend's had a Laguna, it decided it was going to run on its own oil without any human intervention. It stopped when it ran out.

One of the Passat TDIs on our fleet did that not long ago - blown turbo seal, sucked all the oil through and threw a rod.

snipped-for-privacy@italiancar.co.uk (SteveH) gurgled happily, sounding much like they were saying:

It's the usual cause. And I'll bet Renault buy their turbos from the same handful of manufacturers as everybody else...

Yes but it not the same clean oil you put in the engine to start with. And even if it was, it came out of the ground as crude oil - not as Castrol GTX or something.

Used engine oil is heavily polluted and not nice stuff to have in your water supply.

Quote from

"Used engine oil can end up in waterways. An average oil change uses five quarts; one change can contaminate a million gallons of fresh water. Much oil in runoff from land and municipal and industrial wastes ends up in the oceans. 363 million gallons"

it clearly says on he bottle "don't tip old oil in the bin" they also make it easy for you with a freephone number to find out where to dump it.. it's not rocket science.

And they didn't have catalytic converters producing the same effect on engine efficiency as shoving a rag up the exhaust pipe. They were a quick-fix as far as pollutants such as CO and NOx go but put MPG figures back 20 years. The development of the alternative "lean-burn" technology, that promised both increased MPG and low pollution, was abandoned when cats came in.

Isn't "lean-burn" when you run the cylinder head as hot as possible to maximize thermal efficiency?

I read recently (some bloke on the internet) that the problem with running so hot was basically more NOx. But that problem is solved by catalysts. So we can go back to lean-burn after all, which they probably have done, but not yet to the extent of using cylinder heads made out of fancy ceramics.
