Autocorrect fail that should be 20x10mm bolts , but Jaguar did see fit to use that many , i guess they want to stay on at 180mph, plus they designed it to change the oil without needing to remove it so it doesn't matter
Many people are resistant to change and progress and take comfort in outdated ideas
Just to clarify, are you sure? 10mm bolts or M10 are tightened using a 17 spanner. That's big.Many people are resistant to change and progress and take comfort in outdated ideas
Do you mean 6mm or M6, which would be tightened using a 10mm spanner ? Lots of cars have these.
AFAIK the only bolt to have a spanner of the same size is BSW (Whitworth). Pick up a 1/4" BSW spanner and its huge.

Could be useful run in reverse for doing gearbox and diff oil changes.
I’ve used mine in that way - did the diff oil on my mx5 with it. Much easier than trying to contort a bottle into position up under there. Mine looks like the Lidl one but it’s yellow and came
off eBay about 5 years ago, haven’t touched a sump plug since on any of our cars. It’s getting a bit slow now but I just go inside for a brew

Bought and used, it's a bit slow but otherwise ok, haven't used one before so on this occasion I waited until it finished then undid the sump plug and got the slightest of dribbles out so yeah, I am converted!
Imagine there is debris at the bottom of the sump (apparently contentious as all my cars are apparently on their last legs)You have an engine full of warm oil. You undo the sump plug and a tsunami of oil come out washing all the debris with it.
Now imagine what you have just done. Sucked out most of the oil apart for a few dribbles from the top. You open the sump plug and dribbles come out. Do you not worry the debris is still there because there has been no washing out tsunami?
Are you sure you're converted?
If you think there is no debris at the bottom of your sump simply drain the oil one day from the sump plug like normal and put it in a clear container. Wait a day and look at the bottom of the container?

I can't help wonder why people have debris in their engines.
Because they don't spend their lives worrying about insignificant matters. Fresh oil, oil filters all mitigate any debris potential damage(which I think is a non existence issue, cars that suffer from carbon buildups need the whole sump removed to clear pickup pipe, sump plug way wouldn't stop this), if I was really bothered I would stick a magnet on my dipstick. Vacuum oil changes work, have been used successfully for decades, people that spend their nights worrying about debris can remove a sump plug for their satisfaction, whilst I stick a tube in, a few pumps, wait 30 minutes, change filter, refill oil and get on with other things.

Shirley the source of any metallic debris would become apparent in the lab report on the old oil?Vacuum oil changes work, have been used successfully for decades, people that spend their nights worrying about debris can remove a sump plug for their satisfaction, whilst I stick a tube in, a few pumps, wait 30 minutes, change filter, refill oil and get on with other things.

The BMC A Series where the gearbox and engine oil are the same - use a tube down the dipstick?
The Austin 1100/1300’s had a magnet on the sump bolt and always has swarf on it.
What don’t people get that not all cars are less that 15 years old. I took off and cleaned out a Crossflow sump last year that had treacle in the bottom and the remains of two cam followers.
If I did it for a living and maintained other people’s cars then yes i’d consider a pump but on my own stuff - no way!

No.Worrying about the oil change leaving bits of broken engine in the sump is completely missing the point. The purpose of the oil change is to change the oil. All the contaminants that matter will be carried out with the oil, however you remove it. If you have bits of broken engine in the sump, your problem isn't that the oil change is leaving them there, it's that there is something wrong with your engine to have created them in the first place. It's not normal or healthy to have chips of metal in the sump but the chips themselves are not the problem. The fact they're sitting in the sump shows they aren't being picked up by the oil pump since the strainer and oil filter would have collected them if they were. The real problem is that there must be something going wrong in the engine to produce those chips.
The only disadvantage I can see from pumping the oil out, is that if you have an engine fault which is causing something to break up and leave chips in the sump, you don't get to see that evidence of the problem. If you think a normal and healthy engine can produce chips, that's not an opinion I share but still these chips in your view are normal and not evidence of a problem so it doesn't matter whether you notice them.
How many modern engines produce chips, are we talking about the 1960s. A oil change is good for longevity of the engine. If the engine is f
ked it fked, no oil change will stop that.
Anyway don't let facts get in the way of anecdotal evidence.

''While researching this story, we found that some people have posted Internet messages saying they are doubtful of this method. Wouldn't there be some oil left in the lowest part of the oil pan? And wouldn't this oil contain harmful sludge? Sludge is actually an extremely harmful gelling that occurs when water is combined with oil. This has little to do with a successful oil change.
Skeptics were probably intending to say they wanted all particulate matter removed along with the old oil. If the car has been warmed up before the oil change, as recommended, any particulate matter would flow out with the oil.''
We decided to do an oil change on a Honda Fit belonging to Consumer Advice Editor Philip Reed to investigate this further. We sucked out the 3.8 quarts of oil and then removed the oil drain plug to see how much more flowed out. We were pleased to see that it was less than 3 tablespoons. This oil didn't appear to be any more contaminated than what had been sucked out by the extractor. We also unscrewed the filter and found it still contained about a quarter cup of oil.''

Some engines never have an oil change.... ever.....
They get the oil tested every 12 months and then just topped up as required, but the engine is basically sealed for life under normal circumstances.
Granted not cars, but big engines - ship engines, stationary engines, some plant etc.

On the other hand I seem to remember seeing one of the manufacturers showcasing a drop-in module consisting of an oil reservoir plus filter. How cool would it be to be able to do a complete oil service just by yanking one module out of the top of an engine bay and dropping another one in?

We're going round and round in circles here. 
Yep after this I realise I'm never going to believe that sucking from the top is an adequate method of a decent oil change. Its simply laziness to my way of thinking, and this thread is just pushing me further to that conclusion.I'd be knocking money off any car I went to buy second hand if the owner talked about doing his own oil changes this way.
Neither am I convinced of the argument that debris means a failing engine, or my cars engines have been failing for the last twenty years. I guess I'm unusual for having cars over that period of time.
Its interesting to have the discussion though, but I'll leave the discussion now so you can discuss which is the best oil sucker rather than whether you should be doing it at all as its probably a bit of a thread diversion.
