Petrol into a diesel....(warning Juke related!)

[GS250]

Hi All

2 years ago my gf managed to put petrol into her 2017 Nissan Juke 1.5 TDi. Drove for about a mile before she realised and just about made it home before it conked out. Car was drained etc and put back onto the road. She's only done 2-3000 miles since then as she's spent quite a lot of time away from home with me but what was once a very reliable runner is now a total liability. Only has 36,000 miles on now but since the wrong fuel incident, has needed the MAF sensor replaced, numerous running issues including injector faults. For me its too much of a coincidence and that 5 minutes of driving before realising may have made the difference. I know Juke's attract a bit of ridicule in the motoring community but if anything they should be fairly reliable.

Currently in the garage having an injector replaced having broken down last weekend. Gut feeling is maybe they all need to be replaced after the episode.

Difficult to assess from afar but do you reckon persist or chop it in at a main dealer and let the warranty company deal with it in its next life?

Cheers.

That's normal damage from a misfueling incident. The main problem is that the fuel pump uses the diesel itself as a lubricating oil, while petrol is a solvent so does the opposite. What happens then is small bits of metal break off the pump, which go on to block the injectors up.

Replacing the pump and all the injectors is an absolute minimum, but with other potential engine damage it may as well be a write-off.

The MAF sensor, that measures airflow into the engine, I cannot see a connection between mis-fueling and failure of a MaF sensor, she filled with petrol, how much diesel was in the tank at filling up? Was the tank half-full or near empty? That gives an idea of the dilution and reduced lubricity of the fuel entering the pump and injectors.
Forget Nissan, they were cars assembled from quality components, then they were taken over by cost-cutting Renault, go for Honda and Toyota

Yep, MAF failure at that low mileage is a bit unlucky but as you say probably unconnected. Yep...I know about the Renault connection. A far cry from the days of the dull but bombproof Nissan Bluebird and Primera. Yep sound advice re the quantity of petrol versus diesel. She is a blonde by the way........

You are preaching to the converted about what I'm encouraging her to buy next though. I'm not moving away from Lexus now I'm spending 75% of my time in Skye. Can't afford breakdowns when local garages are simply overwhelmed with work and have something of a monopoly on affairs. Agreed Honda and Toyota are probably 2 of the only other brands that I would trust now.

We have an ex-car mechanic at work, his advice is to buy from Honda / Toyota / "German" /. Vauxhall, avoid French / Italian makes. The Ford Eco-boost engine--- avoid

Such low mileage over two years, will the fuel in the have self-deteriorated? Diesel fuel absorbs water from the air, and can be attacked by bacteria creating algae-like residue which may block filters and possibly the injectors too.

 

[thejuggler]

The problems are more likely to be related to lack of use.

Modern diesels really don't like short low frequency journeys, they never get fully warmed up or lubricated from the fuel and parts start failing.

Buy a 1.5 last generation petrol Yaris. Up to ten years 100,000 mile warranty and generally bombproof.

Vauxhall is now part of Stellantis (50:50 merger of Fiat and PSA) so would stay clear of their new models too.

Any mechanic that recommends "German" makes isn't to be trusted - there have been endless issues with VAG engines and it was VAG that caused the problems with diesels with their desire to cheat the tests.

Japanese is the safest route for reliability, with the Korean's (Kia / Hyundai) a very close second.

The current crop of PSA (Peugeot / Citroen and now Vauxhall / Opel) seem to be quite reliable - probaby more so than your average VAG product.

If she's doing low mileage then she shouldn't be using a diesel - diesel engines are the worst choice for low mileage drivers (sub 10,000 miles a year) - a petrol would be a much better choice, the engines don't experience the same problems on short journeys / low mileages that diesels do. An added benefit for your gf is that the unleaded fuel filler is a smaller diameter than the diesel one, so at a pump you cannot put diesel into a petrol engine (you can of course if you use a jerry can which has the wrong fuel in).

 

[GS250]

To be fair the reason for the very low mileage was that she was with me in Greater London than Skye. The car did spend a lot of time sitting about in Portree which isn't exactly healthy either.

Can only agree with the sentiment regarding the other makes. It's divulging a bit but a neighbour has just bought a brand new A class Merc. Another neighbour has a Honda Accord 2L petrol from 2006. Guess which one has been towed back to the dealer twice already? Guess which one only failed once and that with a worn battery. It's pretty obvious but says it all.

What was General Motors Europe (Vauxhall and Opel) was bought by PSA for which read Peugeot.

PSA and Fiat jointly formed Stellantis.

Expect ever more increasing commonality of parts etc over time....

It's a Nissan puke

Just sell it and buy a proper vehicle. Examples include (but are not restricted to)
VW Tiguan

We had a van at work recently that was mis-fuelled (a 2018 Citroen Dispatch), had at least £40 of petrol put in it with it being fairly low on diesel, it was used for about a mile before it got brought back as it wasn't running right (it would have only done low speed driving). This happened last week on Saturday afternoon and the van was back in service by the following Monday afternoon. No signs yet of any permanent damage but it's low speed driving around a caravan site might be the reason for that and the fact that it only happened last week.
It's getting hopefully getting replaced at some point this year anyway so we may never know if it's done any damage.

And no it wasn't me as I can't drive, plus I know it's a Diesel!

As for Stellantis, two of the most unreliable brands coming together to form one company can't end well, it's been bad enough with the Renault-Nissan-Mitsubishi alliance where it seems Renault is the boss, it's the Alfa Romeo Arna/Nissan Cherry Europe all over again!

Anyone would think this "commonality of parts" was something new - back in the 1980s, GM and Fiat worked together to produce a large car platform on which the Saab 9000, Alfa 164, Lancia Thema and Fiat Croma were all based. In engine terms Renault and Volvo worked together on various engines including a 2.7 V6 used in both the large Volvo's and Renault ranges. And more recently there was the Ford - PSA collaboration on diesel engines which saw them used across the Ford, Peugeot, Citroen, Volvo and Jaguar ranges. On gearboxes, Austin Rover bought gearboxes from VW for the Montego and Maestro.

The mention of Vauxhall upthread, I'm on the verge of buying a Vauxhall Viva, 67 reg with 22500 on the clock one owner, £7500.00. In some ways seems a bit to good to be true, but some upthread comments are making me think.

It's not "too good to be true" - it's about right if you look on Autotrader.

I just did a search on there, capping the mileage at 30k and between 2016 and 2018 (so covering the age) and excluding Cat S / N etc and there's a 2017 / 67 with 29k for £ 7,500 at a main dealer. There's a 16 plate with 24.5k miles for £ 6490 at an Independent.

What 'upthread' is making you think ? It's a newish car, which seems to be fairly reliable. Vauxhall's aren't known for being criminally unreliable - as with most things, some of it depends how they get looked after and alot of cheap Corsas and Astras don't get serviced regularly and the owners wonder why they end up with big repair bills.

You say buy a proper vehicle and then go on to list five cars that are targeting the exact same market segment, so would also fall under the realm of not a proper vehicle.

What is the obsession with toy off roaders being used for city journeys? For a "better" replacement to a Nissan Juke, why not buy anything from the enormous list of A Segment and B Segment vehicles available in the UK? The obsession with small J Segment vehicles is just ridiculous over here.

I had resisted the temptation to post something similar!

As someone old enough to remember the family car being an original Vauxhall Viva (which was always in bits and left us stranded more than once!) the thought of owning any vehicle with the name sends me into a cold sweat!

If I was looking for a car in that segment it would be a third generation Yaris 1.5 all day long.

I don't know what J/A segments are, but if you don't want a particularly jacked up vehicle there is the Ford C Max or the VW Golf SV. Alternatively, just buy a regular Focus or Golf. None of those look like hippo on the road.

Blimey you really don't like the Juke . That Hippo reference did make me laugh though.

To be fair my gf's one was actually reliable as hell before the petrol incident. Is not a bad motor for Skye as its a few inches higher off the ground than a standard car. If proper repair is uneconomical then even if it can be patched up for now there's going be a bit of a decision to make. Don't really want to sell it privately with so many potential issues facing a new owner (especially on a small community like Skye). Would happily trade it in to a large dealer though knowing that a multi million pound warranty company will be footing any bill for its next life. After all...they win most times when it comes to paying out. However that would mean chopping it in for something more expensive if we wanted to get a reasonable amount for it.

Did look at late 2000s CRVs with the 2.2 Diesel Engine. Not a bad unit although not as good as their VTEC's. Diesel does kind of make sense in the Highlands. You could have picked one of these up with about 70k on for about £3000 pre covid but even though not ULEZ compliant, they gone up in value quite a bit.

Indeed and fine when no flaws. The issue for the consumer is not knowing when parts are common across brands that they do not realise are connected.

... As for Stellantis, two of the most unreliable brands coming together to form one company can't end well, it's been bad enough with the Renault-Nissan-Mitsubishi alliance where it seems Renault is the boss, it's the Alfa Romeo Arna/Nissan Cherry Europe all over again!

e.g. dump a troublesome Renault and buy a Nissan only to have the same problem(s) again.

The Jeep Renegade and the Fiat 500L sharing the same platform and hence the same transmission problems is an example.

Dieselgate and the cam chain tensioner problems around the same time were at least contained within VAG brands that are relatively well known to have much in common under the skin.

What is the obsession with toy off roaders being used for city journeys?

They’re not toy off-roaders, as they are front 2WD. They are what they are, a hatchback raised up by 6 inches.

As for why, the extra height makes it easier to get my child in their car seat and makes it easier for my elderly parents to get in.

My Qashqai has the same footprint as a Ford Focus. I chose it for the height.

Not brand new there isn't the C-Max was delisted by Ford in 2019 - not surprising as the current generation of Focus was launched in 2018 and the C-Max was based on the previous generation. The Golf SV was dropped by VW in 2020.

The only 'people carrier' style vehicles still on sale new are:

Citroen Berlingo / Peugeot Rifter / Vauxhall Combo (bascially a van with windows).
Ford Galaxy / SMax - though I bet not for much longer.
VW Touran.

That's about it - basically the move has been made to SUV style vehicles, and Ford have dropped the Fiesta in favour of the Puma and it's unclear whether there will be a replacement to the current Focus when it reaches its end of life.

From what I've seen it will be an all SUV line-up, plus the Mustang and GT (the latter is irrelevant to 99.99% of car buyers for obvious reasons!).

Ahhh....the Mach E. Never has the word 'Mustang' been devalued since the days of the Mustang II.

Sod getting the missus Juke repaired... spend it on a V8 powered Yank tank.

Well these days Vauxhalls are pretty much rehashed Peugeots, so this advice may be void.

 

[GS250]

Latest update is £550 spent to install one injector! The mechanic insisted that there's a fair chance the rest will go over the next year or two. SELL IT!

Also trashed a lot of newer cars in general as being mechanically and electronically unfit for purpose. The missus is being wooed towards a Mazda CY-5....even that the mechanic warned against buying the diesel variants. The 2L Petrols are fine and can rack up high mileages. Proper old school Japanese configuration that isn't obsessed with mpg but can be trusted.
