Advance injection timing, use plastic wheel covers, close the upper part of your grille, close EGR. I'm currently tweeking my wifes A4 B5 Avant Tdi. We are currently at 57mpg over a full gas tank (900mi) with winter tires and regular tire pressure.
Once during a period of some financial struggle I took all the seats and stuff out, started using the jsw as a truck for hire to haul random stuff, and at night I slept quite comfortably in the back on a foldable twin-sized bed. I was really grateful to be able to do all of that with such an efficient and cool car.
I had an old 1998 Mercedes A Class. That among other nice features had the possibility of removing all seats, except the driver seat. Just by operating a couple levers. Even the passenger seat was so easy to remove. And they were HEAVY all of them. Probably not so easy for you guys on that side of the pond. To beat that goal easily. Would be to get your hands on a PSA 1.6 liter diesel. Specially pre DPF (and crap) models. Those can be easily found on Peugeot, Citroen, Ford, Mazda, Volvo... Very smooth engines, very economical a pleasure to drive. In comparison the VW TDI feels like a odd tractor! You could hit that goal easily. ;-)
If you were wondering I averaged 78mpg on the car but it was closer to 72mpg.(over a 200 mile journey done twice, I filed the tank until I could see diesel in the filling neck. Then filled it to the same point once I arrived. 1.9tdi pd mk4 golf.
I'm assuming you're somewhere in Europe if you have the pd engine or am I wrong? If so...how many kilometers did you average? I think Europeans always convert mpg differently and you seem optimistic on your average
On the pre DPF and other "emissions" crap that doesn't sound so surprising. ;-) Not much people realize that the emissions crap literally killed our diesels. As an example diesels from that generation had much higher compression ratio! That as been lowered on each new "generation". We are paying more and more for lowered performance and much higher maintenance!
Not only weight with the wheels.. going dropping almost an inch in contact patch also decreases the rolling resistance due to less effective contact area covered between the tire and the road. Larger diameter/more narrow wheels could be quite a gain for mileage. Due to lowering cruising rpm (larger diameter), and less friction to overcome during stop and go traffic (tire contact patch)
@@spottedeuros1529 I'm thinking of doing something similar with my 05' TDI Beetle. I've heard exceptional things about how they run with a tune mileage wise. Even debating getting 185/190mm wide tires instead of using 205's and going to a 17' wheel. I already get in the high 30 low 40mpg range in city but am curious to see how it'd do with less over all weight/rolling resistance and more torque!
put flat disc covers on the wheels, & make the outer body more aerodynamic. That will help drastically. The car's mpg computer is notoriously off though from what hand calculating will get. But for the test comparison it works
Hmmm...reading through the comments I wonder if my DPF is restricting flow...In my (new to me) 2011 A3 2.0 TDi with 113K miles, on my first tank calculation I was at 40mpg with cruise set at 60mph. I just got new tires and my car's at alignment now so we'll see what happens on the second tank.
Hell at that rate weld an aluminum cage together that’ll bolt to the chassis and remove the whole body all together and sit on a very small seat where the driver seat would be, can’t have drag on the vehicle when there’s nothing there to have drag
If you bin all the emissions junk, mod the exhaust, fettle the brakes so there's no drag, drive it so the ECU starts adapting for economy - how you drive makes it trim the fuel consumption - no braking, loads of easy revving, no hard charging, then the fuel-economy indicator will give up as you've gone past what it considers possible - you'll see the magic "---" a lot (that's where the computer considers the figure implausible) - and 124, 128, blah blah an awful lot. When I got mine first, before I spent a bit of time (very little actually) it did an indicated 38-44 mpg at absolute best. 50 if you were lucky. Now if it's under 80 (it's usually well over 100) I start wondering does it need a service. I change the oil a lot - change the oil a lot. 4000 miles done - change the oil. I had the 1.9 pd in a MK1 Octavia - that was a beast - responded to every "economy" mod I made. It used run on fumes. Literally. That thing did a reliable >100 mpg day in and day out. Best VAG iteration ever. I used love the "Range left" indicator feature as the mods I did meant the ECU was constantly upping the "range left" after every 10 miles. You'd bang in 20 quid of diesel, it would say you'd 200 miles till the next fill... then it would re-calculate & say 220... then it would have another shot & say 250... and 50 miles later it was going "I dunno tbh, Lads - it could be 300 - it's anyone's guess.." Literally ran on fumes - most "economy tunable" version of the 1.9 PD ever. It's a toss up between the MK1 Octavia & the Toyota Carina for "Best car ever built" IMO. Either or. I left home once in the Octavia - with not much in the tank, maybe €10 of diesel - drove across the country to collect a car with a son - an MR2 - entire width of the country. Long drive. We got the MR2, started back for home - he put in €50 of fuel - burnt all that on the way home. I stopped with him at the petrol station & got a coffee. No fuel. Octy not need any - still loads of range left. Epic iteration of that ^ engine. I started mucking about with engines to improve the economy/power as a kid & still do. Most people have zero clue how rubbish the factory version "Fuel Trim" is - there are always easy significant gains to be made - on lots of engines, they leave 60% of the economy on the table with the factory trim.
Technically a car will get its rated MPG no matter what except for bad fuel. But a TDI max at HWY speeds will be around 50. But only a Diesel can get this type of MPG by weight standards. A semi 16 wheeler are the most Fuel efficient vehicles available by weight. A semi truck can haul 80k pounds and get 7 mpg...
My 2005 toyota tacoma prerunner racing development has 19 to 20 mpg. I got rid of the spare tire do to the fact its 17 years old and I got a catalytic converter cover and now its 21 to 23 mpg. Oh fun fact my 6 cylinder has 3 catalytic converters and I'm at 187,000 miles on the engine.
On the last run, rain affects mpg as well as winds and whose to say what the barometric pressure was like but that's not here nor there. Rain is resistance when the car is rolling. You go through a puddle of water and you feel the car slow down, just not as extreme.
I regularly get 65/70mpg for a gallon of diesel. Last trip 130 miles I was hoping for 80 as I had an average of 78, but ran out of motorway. That's at a steady 60mph.
There may be lighter brake rotors available for you and you can also go for lighter wheels instead of those steelies. Rotational mass is BIG on mpg. economy tires also may put you well over 70 mpg in that wagon
Low tire light is not because you over inflated the tires. It is because you taken all 4 rims off the car which had tpms sensors programmed to the car. Now that the stock rims are off the car, the cars tpms module cannot connect to the sensors on the wheels. So it sends a signal over to the pcm, the pcm will indicate low tire light. Edit: Also if your looking to remove more weight, grab a hack saw, an socket wrench. Cut pipe between first muffler and suitcase muffler with muffler tips. use socket wrench to remove exhaust clamp that is connecting the first muffler up to the resonator and exhaust flapper. Dont worry, exhaust noise is really NOT loud, you may hear an air flip noise every once and a while, but thats because exhaust flapper opens and closes. Leave resonator connected to exhaust flapper, trust me. If you remove that part then your call will sound like its a flightier jet taking off down the highway. (did this myself) But this should trim off about another 100 or so pounds. My 2009 tdi went from 38 to 45 from this removal, pretty significant gain. You might be able to get more out of it and heavier chances in working into the mid 70s.
I push riders through mine..Lyft Uber who's ever next in line.Singing my original songs ain't such a bad grind Blown away hitting 59mpg in mine always purring perfect rhythm an time.
Don’t know if u still have that car but u should keep because that is amazing mpg I have a 2012 2 dr gulf 6 speed manual and had to baby it to get 44 mpg and that’s not normal
Your fuel in the US is not as refined as what we get here in UK/Europe. All our fuel is low saps. Lower emissions and leaner burning. We get 78mpg with no special effort.
Ok.No one said this but you will loose 30% mpg in rain. Your tires are pushing water up the road. Also. You put smaller tires on? Or are they the same size around with the steel rims. If not that will throw your computer off. If you would like to try this again sometime , I just bought a old 05 Jetta to experiment on for mpg. I will be throwing fuel vapour into the intake and water vapour. If I get results I’ll let you try it . Great job man. I may video my Journey
The Cougle Cafe By Danny Brown mice man. Let me know how it goes. The wheels were the same circumference but a lot lighter. Also it wasn’t raining that much to make a huge difference.
I see Many problem with this test 1 Trusting on board computer it's very Naive You spouse to be Drive some distance and later go To gas station. 1 You change the tires and you don't Check Size of tires this is very important small tires Change you speed My neighbour have this problem Jeep Wrangler My suggestion Compare speed On GPS By the way you tire pressure sensor Stay with original Wells that's why you have this check status on pressure
The weight of the seats help to have a better center of gravity .. its planted lower to the ground so the air doesnt push back on the car at high speeds. And on the way back you are driving in the direction of the wind and not against . Which helps.
my mk6 jetta gets insane numbers when going 50-55 on the old highways get to see a ton of neat towns that way too not being stuck on the interstate seeing the same stops on repeat
Trusting a cars trip computer is full of problems. The only way to stay accurate is to measure over multiple tanks after filling to a known spot everytime.
I got same mileage between 6 speed and DSG. Highway driving is mainly top gear whether you shift it manually yourself or the transmission does it for you.
Prius Who? Fyi if you do a delete you would reach that 70mpg mark. DPF Delete, EGR delete and a Malone Stage 2 Tune is what nets an easy 10+mpg increase.
Just an example of the performance parts efficiency increase. This intake is 2mpg alone. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BMbchti7Qjo.html
Bro, is a diesel.. just amp up your torque, get a good tune and you'll easily be getting 60-70 mpg with out taking anything out and you can drive the speed limit. (Don't forget to replace your fuel filter btw)
Spider Man yea man, my ‘15 bmw 328d has a couple of mods on it including a tune. When I load the boost I can achieve 0-60 in 5.3 seconds (on runflat tires). And when I’m cruise controlling 75mph on the freeway I average around 57 MPG. diesels are badass bro.
Fernando Gonzalez I’m torn between a Jetta sport wagon golf sport wagon or 328d wagon. I can’t really afford the 328d yet but the 328d would be my optimal wagon as it’s awd, leather, large body and sunroof and surpasses the 335d for mpg. I have an 8.0 v10 gas, daily driving is upwards $400 a month in gas, and it’s an 02 so need better mpg as well as something newer. If I had the funds I’d travel wherever I needed to go for the right 328d wagon but for now i think Jetta or golf for insurance and maintenance. I just wish there was a way to get 30+ mpg on a 4x4 diesel truck.
A cold air free flow intake, an air to air intercooler, and the best performance downpipe, no converter and performance exhaust with mpg efficiency tune will get you more than 70. All that race stuff increases power by increasing efficiency. It's almost crazy how much more fuel is used to maintain power after being suffocated by emissions equipment. While your particulates would go up slightly your CO2 will drop by 25% particulates are dirty, but heavier than air. They fall to the ground. CO2 on the other hand, does not. I don't know the exact particulars, but I wonder what the reduction in emissions is?? As they only test at idling under no load. It would be too funny, not funny, if the reduction was 25%. It's all semantics, but you would either use 25% more fuel increasing treated emissions by 25%, or use 25% less fuel, decreasing pre treated emissions by 25%. An absolute net zero. It's also highly likely that this is the case. CO is treated, CO2 is a byproduct and therefore increased. Either way, it's more fuel and more CO2 with emissions equipment. Not so black and white. I don't get how they factor eMPG either. Tesla median kw per mile is 450 in a model S or X. My electricity total cost is 16 cents a kw. Gas is $3.60 on average. Apples to apples that's exactly 50mpg worth of electricity, $3.60 buys enough kw for 50 miles. They are out of their minds with this eMPG inflation. I can legitimately get better economy in a tdi Passat with no range anxiety. 90% plus of electricity is produced by burning carbon. It's not a gain. If I could buy electricity for 8 cents a kw then we'd be talking, I just figured it out, the EPA doesn't include delivery costs and stranded costs that everyone has to pay in all 50 states. California is worse than here, they are looking at 35 mpg at my gas prices lol. It's probably double. Sorry for the rant, I was just putting together my thoughts coherently to make sense of it.
Yes it is interesting. I have always wanted to do some of those mods to a Tdi. It would be interesting to see what kind of mpgs you could get. I have always thought that a Tdi is far more economical than any electric vehicle. I owned a 2015 Golf Tdi and that consistently got 60 miles to the gallon. Sometimes more.
@@spottedeuros1529 That was because the 2015s had the active SCR AdBlue systems. That system controlled NOx emission after it left the combustion chamber. In the 09-14 model, NOx emission were only controlled by dumping more EGR into the intake stream, thus reducing combustion temperatures. Lower temperatures=less NOx, but also less performance and less complete burn. The 09-14s are choked by the high EGR ratio.
Don't forget all the crazy emissions emitted producing those huge battery packs. There was a big study that a Prius is basically putting out the same CO2 amount as an average 25mpg car because the battery manufacture process emits tons of CO2
Duct tape all the panel gaps. strip paint down to bare metal or Polish the paint work slippery smooth and take 3 chocolate laxatives 2hrs before you set off on the test. the ambient temperature will effect mpg too. best off on a cold day when the air is more dense. It's all about cutting through the air as smoothly as possible.
There’s no such thing as 99 octane diesel, high octane ratings only relate to petrol. Diesel as a fuel has an octane rating of ~20, but you are correct that V power is good fuel, due to the additives
Hallo, I have 2014 Vw polo tdi bluemotion, and on 70 km i managed to drive whit 2.5l/100 km 113 mpg, aicondition was on. Long term consumption is 71 mpg. Freeway 324 km in 3 hours 200 miles in 3 gours 5.7 l/100 km 50 mpg 3 people onboard aicondition on
e-primacy wheels, new oil and filters (and otherwise mechanically perfect car), and driving at 62mph will produce around 64mph. But you can't reach 70, because nothing reaches 70. That's another 10%, impossible to get even with b57 BMW engine.
There is something wrong with your videos.. you never say what engine is under the bonnet , you only say if its gas or diesel. On this car there are lots of diesel engine: 1.6 105hp, 2.0 140 2.0 170 etc
no offense but if you're goal is to shave off several pounds here and there(as in.. those rear seat pads weigh nothing)... well, you look like a stout brah... get where i'm going?
