Is this the new bluey whiteness fuel ? Give it 6 months it will be available with Boswelox.

Maybe some stick on mini flag poles for the wings as well............ Only joking

Having owned both a 1.2HTP (did 98,000 miles before selling it) then buying a Greenline 1 and using both on the same 110 mile commute, I would actually lean toward the HTP. The HTP was a great little car to drive, I did 70-80 often and it handled it fine, just don't expect it to accelerate hard much above 60. Yes the diesel is proportionally more efficient over longer distance, but over 20 miles each way taking the fact petrol is cheaper the margins arent significant over a year. As previously mentioned the HTP is simple and cheap for maintenance. I found the Greenline a bit of a pain in towns as the gears are much longer. To be honest either car will be fine, its just in the same situation I would have the HTP. SWMBO has my Greenline now as I have a company hack, she does about 20 miles a day in it just fine, but the economy has dropped by about 10mpg as she isnt doing the longer distances at steady speed with a fully warm engine as I used to. Not definitive as the GL2 is very different to my GL1 so drive both, over the same distance you propose and make your decision then.

Its just semantics. There is no separate tank, just a void above the vent point. Depress the valve you can fill it. Thats all.

I do the expansion thing on purpose when going straight out on a long run. You can just fill till it clicks off then push the nozzle gently against the relief valve, you will here the air purge out then you can add some more fuel. I do this a few times to brim it. I never do it when not going on a long run or if the car is being left as there wont be any expansion space. Its never spat out fuel on the floor even when turning hard so I dont have a problem doing it. If you search valvectomy in here some folks take the valve out on purpose so it always brims.

Mines an 80 HP PD Green line. Yes its a bit 'tractor' like lower down in the revs, but pulls really well and is very efficient. I quite like the rattly engine tbh. Its not the sort of engine you lug at lower revs, it vibrates a bit if you do and no torque down there anyway. Had mine since new and at 70k now. Just had cam belt done. Only ever fault was a differential pressure sensor on the particulate filter which yours wouldn't have anyway unless its a green line. Swmbo is inheriting mine soon and plan to keep it a good few years more. Green line 1 has different engine mapping and gearbox plus dpf but essentially its identical to standard pd80.

I would be a bit annoyed with 50mpg. My old fabia 1.2 htp could manage that plus petrol is cheaper. My greenline 1 (pd) easily gets 65mpg in winter driving with disregard for economy on my 110 miles per day commute. 70 mpg in summer is the norm. That's just driving with the flow of traffic mixed road's and outside lane speeds on the dual carriageway. Its still shy of the book figures but I am more than happy with my economy. Even ignoring the ridiculous EU figures 50 mpg for a new diesel green line is total crap IMO. I am soon to receive a new company car so my green line will go to swmbo. I Intentionally avoided a new Skoda diesel as I still have to pay for my fuel. My dealer admitted they get complaints about economy for the new cr engines. This is nothing to do with EU figures. Just crap economy compared to previous models like mine.

Biodiesel is harmless to DPF. In fact its better than dinodiesel as its got no sulfur. What isnt so good is that post fuel regen which can sometimes dilute the engine oil is worse with biodiesel as it doesnt vapour off so easily as dinodiesel. Its also a good cleaner and a better internal lubricant for your HP pump...not that my PD has one. For those that like the taste of millers its just Naptha, 2 ethyl hexyl nitrate (cetane boster) in a suspension of Kerosene. Harmless to DPF with benefits open to opinion. Personally I don't think you can beat a good long blast down the fast lane at high revs to keep it clear. Mine gets that every day and after 67K is better than ever. EDIT: All forecourt diesel has up to 7% biodiesel anyway. (EN590)

If it helps I have a Greenline 1 Tyres are 165/70 R14 The rims are: 5J: This is 5 bolt holes with a 'J' type rim contour profile 14H2 : 14 inch diameter wheel with a H2 bead hump profile ET 35: This is the wheel offset from the mounting point 57: The size of the hole in the middle PCD 100: Pitch circle diamter of the 5 bolt holes

Errrr...... I am not an automotive genius but what I do know is the DPF is not kept at a constant high temp by extra fuel. Its sits there as a dumb box of filtration media until it gets to a certain point of restriction, then the engine modifies fuelling for a short period to raise the temp, incinerate the soot and blow it out the back as you drive. Mine regens approx every 120 miles and doesnt appear to have any effect whatsoever on that journeys efficiency. My car wont actually regenerate until the blue light goes out. I know this because the PD is so damn obvious when it regenerates My PD engine gives excellent economy. Whatever the problem is with the CR I dont see the DPF as a major factor, if it was my PD would be equally as inefficient as the CR engine. I still say the lower injection pressure of the CR and the multiple injections to make it quiet and driveable have a cost.....efficiency. Not saying I like DPF, TBH its just something else to go wrong, which it has once when the differential sensor threw a wobbler. No fault codes shown and driving unnafected but the regens went all weird . Took it to garage and they read the fault code, all sorted now with a new sensor.

ooh, handbags at ten paces

My unqualified and best guess would be that the wasted fuel is partly due to the multiple injections per cycle that make your car so much smoother and quieter than mine, but not necessarily the most efficient use of fuel to make the thing go. Combined with a less atomised spray when compared to a unit injector (PD) that has higher injection pressures which 'may' make the burn less efficient. If its smoking more because its a less efficient burn you wont see it as the DPF collects all the crud. Or the above is all balls so pay it no attention :no:

Just to clarify the slight typo. I get 70 mpg in the summer when driving at 70mph on a motorway. Steady speeds. Yesterday 55 mile trip from Aldershot to Littlehampton mixed roads gave 64mpg. Have a Yeti today as the cars in for its cambelt change and service. Best i got out of that at steady 60 on dual carriageway was 42mpg indicated.....Its a petrol engine but no idea what capacity.

I have a Greenline 1 with a PD engine. Summer 70 mpg is easy driving normally and 70 on motorways, mix of dual carriageway and a few towns. In winter this drops to low 60's. Still a bit shy of book figures but imho its really good economy. If I drive like a hippy in summer it will beat 80mpg. The PD injection pressure is way above any of these new common rail engines and its also quite rattly. Smooth sounding diesel with a square power band clearly comes at a price. The aerodynamics of my car cant be so different from the GL2 so really its just the new CR engine that isnt as efficient as advertised. Diesels used to be simple, high pressure external injection pumps, no EGR valves or DPF corks stuck in the exhaust. So much technology in them now to help trees breathe but does nothing for economy. Skoda isnt the only manufacturer to exercise the figures or MPG test manipulation. They all do it. Fiat twinair is a typical example, doesn't come close to book figures. Until manufacturers put a car from the production line on a real road at set speeds with a proper load then I consider all advertised figures as pure bunk. I have been fortunate, after over 65,000 miles my curent Fabia has saved a fortune in fuel compared to my old petrol HTP. I wont be buying any new VAG group diesel in the future though, unless they start making PD's again, fat chance.

I have the GL1. Done over 60,000 in it. Summer averages around 70 mpg and in winter around 65. Thats driving normally. I tried driving like a tree hugging hippy a few times just to see what it could manage on my 55 mile trip to work, best was 84mpg. I dont bother with that anymore and just blat it up the fast lane with the reps. Still manages mid sixties at 'motorway' speeds. Saved me a fortune in fuel this car has and from what I read here it knocks spots off the new CR engines for economy. Yes its a bit vibraty and unrefined but I quite like it. Never bother with 5th gear under about 55, it prefers to run around 1800-2200 rpm. Summer I get 550-600 miles to reserve. Mine has the skinnier wheels than a standard Fabia. 165's I think. Best tyres after trying a few was the Michelin Energy. TBH no tyres are expensive as they are narrow. Mine regens reliably every 120 or so miles, doesnt matter how you drive it. Obvious to me when it does it, you lose a bit of power and the engine exhaust note sounds a bit more 'diesely' for 10 mins. Only had one fault in 3 yrs. The differential pressure sensor on the DPF failed. No warning lights but i recognised the regens went a bit random. VaGCom showed a logged sensor fault so easy change and good as new.

Just so long as it isnt your DPF light. If it is and there is a fault with your regen system you run the risk of filling your DPF beyond force regen point and THAT is seriously expensive.

Confirmed by dealer and skoda assist. 3 yrs unlimited for skoda assistance

According to the small print its 3 yrs, no mileage limit. Unless I missed it ? The warranty is only 60k after 2 yrs but the assist is 3 regardless

Sorry to hear about your engine issues. I had been under the impression these PD's were close to bullet proof but that clearly isnt the case. I have the identical Greenline to you however I have never had the DPF light come on in all its 56,000 miles. I do a lot of motorway and A road driving, 110 miles per day so may explain it. I ran V power for a while just to see if it was of any benefit. The car regenerated more often at first but then the regen frequency reduced with every subsequent tank. About 20 miles more before regen on average. I sort of assumed it was the cleaners taking off the gunk and throwing it in the DPF, once it was all gone the fuel burned cleaner? I know that V power uses a percentage of gas to liquid stock which produces less soot which may be a factor. After a boring evening a while back, searching for info,I found V power uses an injector cleaner as part of its make up, though i assume more dilute than a single treatment type. I didnt notice any extra mpg at all and thats true of every fuel i have tried. I havent ever used supermarket fuel, usually its BP,Shell,Total and very rarely some Murco flavour. If I had to say which I preferred for no reliably quantifiable reason other than "gut feeling " I would say Esso. Maybe a few mpg more but cant really give evidence of that. Probably the best thing for a diesel is work it hard, keeps itself clean by burning off any crud and the fuel is perhaps a minor player in helping out. Cant be good sticking a porous cork on the exhaust either which is what all us diesel drivers have to look forward to from now on.

Would have thought more likely an egr fault or a ****y sensor. If it was your DPF sensor then would expect to see the DPF light come on. I have a GL 1 and its obvious to me when it regens, were the DPF sensor faulty the car wouldnt regen when needed and put the DPF light on. Whether the exhaust control light would light for a failed DPF differential pressure I dont know. If it was the sensor they are I think about 45 quid and easy to fit. If you drive for best economy then maybe its a gummed up egr valve. My GL1 is near 60K and spends its life blasting along motorways and A roads. I still easily get 65mpg (shows as 70mpg) and regens every 110-120 miles. Let us know what the fault was, might be useful to me in the future!

Thats one of the reasons Honda has developed the NC700. Its half a Honda Jazz engine with a few tweaks resulting in a motorbike with high torque, low reving and over 80plus mpg. Same power output as typical 500 twin. Pure motorcyclists scoff at it but its not designed to ring out every ounce of power and rev its nuts off. I am seriously considering one. Bikes can be made more efficient, just up to now unless you want a C90 or an Innova there wasnt a whole lot of choice

Not sport tyres but my skinny wheels GL1 has had various rubber shoes and the best has been Michelin Energy. Good grip and really last well. Quiet running and very good in the wet. No idea if available in your size....

Only R134A is permitted in UK for aircraft aircon. Its a Hydrofluorocarbon. It replaces R12 a Chlorofluorocarbon. Not sure about cars but I guess its under the same EU law. Supposedly after Jan 2011 no aircon gas with GWP greater than 150 can be used but I am sure they are still churning out cars with R134A in them. No suitable replacement exists so maybe they got an extension. Problem is tree hugging aircon gas requires a very high pressure system.....cars just arent built for that yet.

I had to google that.....bit before my time. The newish cbf 125 is supposed to do 140mpg. Not with my belly on it I suspect. Even my old Kawasaki 500 does about 70mpg. With eco driving and rip off fuel prices being so prominent its no wonder companys push the inflated figures. Economy sells, even if it is a legally fiddled figure. I do wonder if newer cars are really any better than say 10 years ago. Newer cars are safer but heavier and with all the emissions control bolted on its no wonder economy suffers. Someone else posted on here that mpg is the new 'BHP'. Sums it up really. I did see that real world figures for the new VW up! (Citigo) are mid fifties. Thats not far off book figures for combined. Seriously considering the Up! or Citigo for SWMBO. We buy cars and run them till they drop, dont want a more complicated Tsi and the even the Fabia is bigger than needed.

As with most things in the real world I tend to listen to those actually experiencing the problems. Of course driving a car in a specific manner focused on economy is going to help, but its not specific to one particular model. The point is that there are many people who despite following advice and changing their driving style still get poor economy from the cr engine. Same applies across Seat and VW using the same engine. Fiat is the same with the twinair engine which a friend has and despite all attempts to modify driving style the economy isnt even close to whats advertised. Given the real concerns people have over unrealistic economy figures i do feel its a little patronising to tell them it will all get better in a few years when they put a load of miles on the car or they are just poor drivers. I have the utmost respect for your knowledge of all things motorised but I reserve the right to disagree with you without having to spend months researching an opinion....thats all. I shall leave the remainder of this particular thread to your extensive research.
