I drive a Grand Picasso and a Nissan Maxus van , both have to have as blue added , the latter seems to do so many fewer miles before another 5 pts has to be added .
Are there any tips to reduce the amount used , I carry a lot of weight, does that make any difference , and shorter journeys , often in London .
Also is there good quality or bad ad blue , I’ve bought from Halfords and Costco , where do you all buy yours from
|
|
What’s a Nissan maxus van ? Thought these were electric?
|
|
I believe it's just squirted in as a ratio to the amount of diesel used, although it may vary across different makes and models of vehicle.
|
FWIW, my brother has a 2019 diesel Grand Picasso / Spacetourer and his threw a DPF fault. It was a long and complicated explanation that I can't faithfully reproduce but the upshot was an Adblue delete.
It still has a DPF, it works fine, and whatever needed flashed was flashed so no faults shown.
|
>> the upshot was an Adblue delete.
Isn't this illegal though? I remember seeing a documentary covering Police doing a sting on commercial vehicles looking for commercial vehicles that had deleted SCR-Adblue and/or DPF systems.
|
30k miles over 4 years in my Tucson 1.6 diesel and I've never had to add AdBlue. The gauge is always full.
I wonder if they top it up at services?
(Had I known my situation would change so dramatically, I would not have opted for a diesel, though it can be very economical.)
|
>> I wonder if they top it up at services?

I'd guess it's like screenwash; if they can sell you a few ml/cl at 10* what it costs ordinary retail they will.

I wouldn't be surprised then. One of my rare sensible decisions was buying a service plan for the Tucson. It wasn't cheap at £650 for 5 years, but the costs of the services so far have been £1,200ish.

Have you had it from new? If not, then somone has done an AdBlue delete.
If you have had it from new, then that's most odd - does it definitely have AdBlue? I don't think the 1.6 VW engines have it. If it does, then based on your mileage is should need refilling two or three times per year.
|
>>Have you had it from new...
Yes. First registered keeper.
Definitely has AdBlue. There is the electronic gauge on the dash and the blue AdBlue cap next to the fuel cap.
I'll have a word with the dealer.

I'd be minded to leave it alone. VW wanted to do an update to wife's 6yr old Tiguan but other than it being to do with the SCR (AdBlue) system they didn't know any details.
I refused it - it had worked fine for 6yrs/40K. I read afterwards that it significantly increasd AdBlue consumption. Her car (2 litre with DSG and 4Motion, doing 38MPG) was using a litre every 500 miles.
Apparently early Audis with AdBlue didn't use any at motorway speeds so they could run between services without being topped up. We were told the same thing when we ordered Tiguan, but the info kept changing.

Absolutely. If it's not broke don't fix it.
The chap in my story who isn't of course my brother slightly regrets the way it went, although repercussions or further problems seem very unlikely.
The fault is fairly common and is often caused by damage to wiring hidden by the fuel tank. It turned out that was the case and had he known he would just have pulled the tank himself and fixed the wiring.
Very annoying because if they had made it properly it would never have gone wrong.

Skoda Superb bought in January this year is our first car needing ad-blue.
According to the dash a full tank of ad-blue will last c1800 miles.
After driving around 2k miles range is down to c1550.
I need to add a bottle of ad-blue to the wee box with screen wash, oil, brake fluid and other bits/bobs in the boot.
At a price of around £1.40/litre I don't think it's cost is a deterrent from going to the supermarket!!
|
|
Just be aware of stocking up on adblue if it’s cheap . The shelf life is around 12-18 months .

And I've been told it should be kept in a cool, dry place, out of direct light. So buying it from garage forecourts where it's been sitting in direct sunlight might not be the best option.

Neither.
8,000 according to the indicator when it was delivered to us having been filled.

Is it me, or do those two statements seem mutually incompatible?

Yep, 1800 was a mistake. Should be 8,000.
Need to get in the habit of checking it.

The new motorhome is the first vehicle I've need to "wrestle" with adblue with.
Fiat seem to quote an average of 125 miles per litre, which would need relatively regular top-up with a 19 litre tank. (remember, it's a 3.5 ton "brick").
It was filled for me on handover, and if I'm to believe the gauge, I seem to be doing somewhat better than that, possibly even double.
Given that the fuel consumption is something like 15% better than its predecessor, I'm not over-worried about the financial effects.
|
|
Most searches seem to suggest that adblue useage is about 5-10% of your fuel useage.
|
|
Only just found out that Adblue isn’t actually blue. Who knew?
|
>> Motion isnt blue either.

Come to that, I've never seen a blue tooth.
|
Ah that has ryhme and reason.
quote
"The name "Bluetooth" for the wireless technology comes from the 10th-century Viking king, Harald Bluetooth, King of Denmark and Norway. The name was chosen as an analogy, comparing his ability to unite warring Danish tribes into a single kingdom to how Bluetooth technology unites different devices under a single protocol. The Bluetooth logo is also inspired by Harald Bluetooth, featuring a bind rune combining his initials, H (ᚼ) and B (ᛒ), in the Younger Futhark script.
Bluetooth was invented by Jaap Haartsen and Sven Mattisson"
Hence the Norse Scheiße

And your next question answered
Quote. Harald Gormsson, the 10th-century Danish king, was called "Bluetooth" due to a dark or blue-colored tooth, likely a dead or decayed tooth. The name, "Blåtand" in Old Norse, translates to "bluetooth" or "dark tooth". The nickname was used to describe his distinctive dentition.

Can't imagine why people want cars with such complexities, and so costly when they go wrong. Even the cost of servicing as quoted is comparatively horrific.

And me!!.
I've had three modern diesels all with common rail type high pressure injection stuff. Two went well over 100k. The Xantia had one injection issue, a valve in the system rather than an injector.
The Berlingo threw a wobble with an injector which was an expensive fix but otherwise never missed a beat.
I've no expectation that a petrol engine would have been better or any less complex and I prefer the torque of the diesel for towing.
If we decide we cannot manage with just one car then the second is very likely to be electric.

Interesting to see how long manufacturers continue to produce diesel cars. Market share is falling fast so likely to be ditched soon I guess.

Some manufacturers have stopped them or don't offer them in the UK any longer.
A Dacia Jogger in diesel form might have been worth a look.

Not for me at the moment…I very rarely do long drives, but occasionally I do and range anxiety would be my downfall.
Yesterday I drove 817 kms (506 miles)…left Bilbao at 08:30 & arrived my rental apartment in Moraira on the CBlanca 11 hours later. I suppose with forward planning I could have found a recharging points, but I rarely know my route in advance as a wing it, depending on weather and finding places of interest to stop.
Used the motorway network ( bit stressful) to escape Bilbao then left at J1 once out of city limits. Wonderful drive through mist shrouded wooded valleys to Miranda de Ebro then a slow tour of Rioja country, stopped in a few villages to mooch around before joining the lovely dual carriageway the A23 some 120 kms south of Zaragoza for the long haul to Valencia and the AP7 south.
Enjoyed a delicious €13 menu del dia before the A23 which runs SE at between 800/1100 metres for mile after mile and was almost deserted.
AP7 coast motorway was manic as always..a Tesla was in lane 1 driving at 60/70kph so must have had low battery issues…quite a dangerous scenario given the volume of traffic and trucks doing 90kph.
Arrived far more refreshed than my 298 mile schlep south to Portsmouth on Thursday. Would have been evening more relaxing in a car with less wind & tyre noise, but Sofia Suzuki behaved as per normal.

Well you might when you look at depreciation. ;-)

Is it really a lot worse than a new dino fuel car? Maybe I suppose...
I've been lucky and jumped on really cheap offers from MG. So roughly my first one lost 40 - 45% in the first 3 years, though I probably let it go a bit cheap just to get rid.

For comparison. My Tucson diesel DCT (auto) is 4 and a bit years old.
I purchased it for £20k new (£9k discounts) and have just looked up the WBAC offer and it's a shade under £15k. So 25%, but about 50% if I had paid full retail.

When I was doing EU car transport my AdBlue consumption was 3% of diesel usage, in a 2018 Disco 5 sD6.
|
We're now almost 1000 miles into a French trip, and the van isn't yet calling for a top-up (it measures in quarters of a 19l tank, and is still showing "full", though I suspect it will lose the top quarter soon). Given it had some miles under its belt already since the last (and first) top-up it's already at the 250 miles per litre point, I strongly suspect the consumption is related to driving conditions.
Compared to the UK traffic volume on the roads we've used (toll motorways avoided) has been light, and the van is still delivering 38mpg, which is quite a surprise.
Down through central France and then along the Lot valley West to East in temperatures hovering around 30° it's been most enjoyable largely off the main tourist traps (or at least pre-season), and Bourdeilles Albas and Cajarc have much to recommend them at this time of year.
Oradour sur Glane caused a bit of reflection, not really a tourist destination but worth a visit if only once - we shouldn't forget.
And tonight, 26° and a thunderstorm, now just departed.
It's a hard life!
|
I was beginning to think the gauge had stuck, but it dropped the first quarter just as we pulled in to a stop today. 1548 miles so far, and it's back to the point where I put 4 litres in some time before that.
I think expecting 400+ miles per litre under all circumstances is a bit optimistic, but the consumption is lower than my expectations by quite a factor.
|
>> I was beginning to think the gauge had stuck, but it dropped the first quarter
>> just as we pulled in to a stop today.
No such luck for me; my gauge is digital ;-D
|
|
...so is mine, but it only measures/displays in quadrants. ;-)
|
The Superb's Ad Blue range of 8,000 at delivery is now down to 6,000, broadly consistent with miles we've done since January when we picked it up.
It's going to the Western Isles and back in a fortnight's time and a 2 week plus 'van trip in France is booked for July.
Will probably fill it ahead of the latter.
|
|
I wonder why , petrol forecourts don’t sell ad blue , I’ve seen Ad blue in plastic containers from 1.40-2.20 per litre , I’m sure they’d make enough profit if garages sold it at £1 a litre
|
Been one place where it was on a pump alongside diesel.
Possibly in France rather than UK.
|
|
Our local convenience store/filling station has AdBlue on a pump. Having refilled my car twice, once from a container and once from the pump, filling from the pump is far easier and less messy.
|
H/book for our Picasso says not to use the pumps, but I don't know why - as long as it meets the EN std should be OK. The filler is inside the car (and flipping awkward to get to at that!) and pretty small, so maybe there is a concern that it would go everywhere if you tried to fill from the pump.
Avoid the forecourt stuff and shop around; B&Q currently got 5l bottles for £4 which is pretty cheap. On line deals available if you can wait a few days - but I doubt you can better 80p/litre.

Sudden recollection of when I was young and with a 2 stroke scooter or motorbike, I used to have to pump 2 shots of something in alongside the petrol. I thought we'd moved on from there :-)

I seem to remember that as a upper cylinder lubricant. 1d a squirt in the 60s, and one squirt per gallon.
|
|
If it was a 2 stroke was it not the oil?
|
Is upper cylinder lubricant not a just a fancy name for oil? :-)
Wasn't 1d either when I used it, which would have been early 70s.
But otherwise - that's it!

When I started driving back in the 60s, there was a belief, particularly amongst older drivers, that the engine should be revved before switching off to leave some fuel in the combustion chamber. They thought that would make starting easier.
Then came the theory that doing this would wash any oil off the cylinder walls, accelerating wear.
I can see how the belief that UCL would replace this oil.

Didn't 2 strokes need oil added to the fuel hence the exhaust smell?
|

They did. Adding the oil to the petrol died out with BSA Bantams, the Japanese introduced separate oil tanks, did away with the guesswork.
|

I assume two stroke engines are now illegal due to emissions regs?
|
>> I assume two stroke engines are now illegal due to emissions regs?

Not illegal but strict emission laws have to be met. A British company called Langen still produced a 250 up to recently this year, albeit at a hefty price tag of around 30k. They are very much a hipster thing, the extra weight of modern bikes plus emission restrictions mean any 1970's Japanese blue smoker would blow it into the weeds.

>> introduced separate oil tanks, did away with the guesswork.
Not really, my 1928 Velocette has a separate oil tank - the basic engine design goes back to around 1913 with a separate oil tank. It's a bit rudimentary as the oil is sucked along the crankshaft and then mixed with the petrol in the crank case. Rate of oil is adjusted via a needle valve on the crankcase. The later GTP engine (1930 on) used a throttle controlled oil pump to give better ratio control.
Now, if only I could get it to run....
|
|
I experimented with running a two-stroke on castrol R for a while - glorious smell. Found the remains of a can in the shed and thought I'd put it in the mower tank (no cat to worry about). I just couldn't get it to mix with the petrol. Modern fuel, old R, or did we use some special stuff back in the day?

There was no bio in the old fuel.
