Had my 9-3 VS TDi Auto for a couple of months now, and I'd like to compare notes on the MPG that I'm getting on the Motorway/Highway.

From day one the averaged MPG was around 40, but now that I've figured out the CLEAR button thing {to get moment to moment MPG, at least for a few minutes} I'm impressed with what I seem to be getting at say 70 MPH on a flat stretch of road, averages around 55+ in the last couple of weeks.

It's even better to see 99.9 MPG on a down hill stretch, grin...

Is that average ? first time I've had a diesel, and I'm well pleased.

Still thrilled by the car on all points too, glad I did the homework by using the info on www.whatcar.co.uk

Hello again Bob,

:cool: Yes, this is the sort of MPG you can expect on medium to long highway runs as I did with my Passat. That's why diesel cars now outsell petrol engined cars in the UK, apart from the fact that we have masses more torque than a petrol engined car of the same BHP giving you great acceleration up long gradients etc. Have you noticed the quick build up of speed at low revs? This is the result of having a very high torque engine. Have you noticed what your 6th gear MPH/ 1000 revs is showing? The SAAB engineers have slotted in a gearbox that has a 40MPH/1000 rpm 6th gear ration... awesome I think. So when doing 80 MPH on the highway you are only ticking over at 2000 rpm. This also helps to keep the fuel consumption down as you have noted

As you say "I'm well pleased" and I can only agree. This is my second Diesel car and I just love it.

TORQUE is KING

:cry: PS still only getting 39 MPG with mine but I am not taking it long runs on the highway .. only local runs at the moment.

Hello Iain...

Yes, this is the sort of MPG you can expect on medium to long highway runs as I did with my Passat.

Ah, well, the run I did a few days back was to Blackpool, and although around 90% of the journey was on the Motorway the car averaged 47 MPG on the 28 mile trip, hey I'm happy with that...

That's why diesel cars now outsell petrol engined cars in the UK,

Hmmm, dint know that, art sure ???

apart from the fact that we have masses more torque than a petrol engined car of the same BHP giving you great acceleration up long gradients etc. Have you noticed the quick build up of speed at low revs?

Sort of, at 70 MPH the rev counter varies between 1500 & 1700, in my 2004 VW Passat 4.0 4WD Auto, it would have been around 2500-2700.

This is the result of having a very high torque engine. Have you noticed what your 6th gear MPH/ 1000 revs is showing?

6th Gear ??? I've not got any gears on my car :nono; it's an automatic :lol:

The SAAB engineers have slotted in a gearbox that has a 40MPH/1000 rpm 6th gear ration... awesome I think.

Yep, I agree, as a {now retired} engineer I have always bought my cars based on the engineering expertise of the stable {so to speak}, taking consideration of things like a well engineered/sophisticated engine, and then things like a good suspension.

Crash survival stats always came top of my list though, having worked for almost 30 years on crash investigation, {on aircraft, mostly military}, I've always looked at what happend in the worst case scenario, will I walk from it or die as a result of it, so Saab, Volvo and VW have been cars of my choice in the last 7 years... I never buy a car unless I know {and am satisfied with} the crash stats, the last thing of concern to me is what it "looks like", it's how safe the integrity of the car is, how well it handles, and then the comfort of the drive etc...

Some companies are dedicated to giving us the best in crash stats, engine design, etc etc, I can afford to pay them, so I reward their considerations by buying their product.

So when doing 80 MPH on the highway you are only ticking over at 2000 rpm. This also helps to keep the fuel consumption down as you have noted

80 MPH {Pas Moi, grin}... yea, I'd say that was about right, although I'm reliably told it might well be 1800 RPM.

As you say "I'm well pleased" and I can only agree. This is my second Diesel car and I just love it.

Never ever had a diesel before, not a lot of incentive when I was in Canada and the US, gas there is still around 40-45p a litre, arf the price we are being ripped orf for, sigh.

TORQUE is KING

I'll vote for Him, anyone afore Wing Nut !

:cry: PS still only getting 39 MPG with mine but I am not taking it long runs on the highway .. only local runs at the moment.

Nip down to Blackpool then ! guaranteed 45 MPG on that run, could be the sea air though.... or the Molybdenum Disulphide I slipped in a couple of weeks ago, been using that for well over 40 years now, on cars, boats, lawn mowers, snow blowers, you name it {even me trainers :lol: }, and I swear by it.

some more info

Hello again Canada Bob,

In reply to some of your writing I reply:

That's why diesel cars now outsell petrol engined cars in the UK,
Hmmm, dint know that, art sure ???
Answer:
;oops: OK slight exaggeration .. Its about 35% excluding trucks in the UK. Quote from SMMT ” Diesel market continues to grow: Despite the overall market slowdown in the UK the new diesel car market has continued to grow. In June it posted its 57th monthly rise!” BUT in Europe as a whole Diesel engined cars DO outnumber Petrol engined cars.


6th Gear ??? I've not got any gears on my car it's an automatic
Answer:

:nono; Even automatics have gears unless you have a variable speed drive and the SAAB doesn’t. If your auto SAAB has the 150 BHP engine you do have 6 gears. The 120 BHP engine has 5 gears. >>> Saab Sentronic (Automatic 6-speed) on 1.9TiD 150bhp/ 2.8 V6 Aero >> 6-speed automatic transmission, that also doubles as a sequential manual transmission. As an option, you can also choose buttons for manual shifting on the steering wheel.



.... or the Molybdenum Disulphide I slipped in a couple of weeks ago, been using that for well over 40 years now, on cars, boats, lawn mowers, snow blowers, you name it {even me trainers }, and I swear by it.
Answer:

I used Molybdenum Disulphide many years ago on a few applications. One of them was in my Mini engine. I also used it on my cycle wheel bearings and it certainly made a difference. I whizzed away from everyone when freewheeling downhill. I havn’t looked for it or used it for a long time now. :suprised; Is it wise to put it in your engine? I know that in some applications in Industry it is not recommended for use because it is too slippery for some machinery parts that require some friction to work and could damage some parts like hydraulic tappets etc.

Best regards, Iain

Hello Iain...

OK slight exaggeration ..

I'll let you off then ;)

In June it posted its 57th monthly rise!” BUT in Europe as a whole Diesel engined cars DO outnumber Petrol engined cars.


Can't blame them, I can't see any reason to induce me to go back to being a petrol head...


6th Gear ??? I've not got any gears on my car it's an automatic
Even automatics have gears


Nope, yer wrong, I just looked, not a gear to be seen :roll: haven't owned a car with gears since 1982 ! :lol:


If your auto SAAB has the 150 BHP engine you do have 6 gears.


Yep, it is the 150 BHP, I think the discount I got on it might have been down to them not bothering to put a gear box in it ;)


.... or the Molybdenum Disulphide I slipped in a couple of weeks ago,

I used Molybdenum Disulphide many years ago on a few applications.


Moi Aussi, learned about it in 1965 whilst serving my apprenticeship at De Havilland Aircraft here in Lancashire, amazed me the bench tests they did on piston engines with Moly in the oil... so I've used it since then...


One of them was in my Mini engine. I also used it on my cycle wheel bearings and it certainly made a difference. I whizzed away from everyone when freewheeling downhill.

Hang on Iain... yer not 15 stone though are yer :lol:


I havn’t looked for it or used it for a long time now. :suprised; Is it wise to put it in your engine?


Definately, petrol or diesel, auto or marine, even 2 strokes... believe me I've spoken to them all on this topic in the last 40 years, particularly Noranda in Canada, where I used to get "samples" of the scientific grade, up until recently, sigh...


I know that in some applications in Industry it is not recommended for use

Very few, I've seen it used on Tank turrets, rifle bores, and just about every application for internal combustion engines, I don't know of a downside, and after 40 years of experience with Moly if there was a downside I'd know about it {for our usage that is}. You don't want to burn Moly though {like in a jet engine} as it turns into Molybdenum Trisulphide {and that's an abrasive}... but in the internal combustion engine we never see the temperature needed to achieve that.


because it is too slippery for some machinery parts that require some friction to work

Yep, obviously stay away from clutches...


and could damage some parts like hydraulic tappets etc.

Not sure how though Iain ???

Hello Iain...

Thought I'd post a couple of links re Moly, what it is, how it's best used and all that... Remember the first little buggy then went to the Moon ? guess what lubricated the wheel shafts on that, grease of oil would simply have fallen off due to the very low temperature and the vacuum on the Moon, a bit of an obscure useage, but one to show that NASA trusts and uses Moly.

The thing that impresses me is that Moly won't fail this side of 500,000 lbs per sq inch, and I don't know of a machine capable of producing such a pressure.

Here's the links...

The above should give some insight into Moly.

Bob, Thanks for your putting in the links. I will have a look when I get the time .
Funny, I used to work in the aero industry (Avons, Speys, Olympus and RB211 stuff) and I guess that is where I picked up the idea of Moly not being any good in some applications and you informing me about not using it in very high temperature applications. Thanks.:)

And I guess you are kidding me on that your SAAB has no gears?!?! If not, they sold you a dud and you aint goin' nowhere soon.:cry:

Iain

PS: Maybe the fact that we were both Aero apprenticeships led us into SAABs. This is my 4th SAAB but is has been 20 years in between the last one and the one I own now.

Hello Iain...

Yer welcome as us Canadians say ;)

Much of the "work" I was involved in before I set sail for foreign shores was on, Red Top, Bull Pup & Sea Slug missiles, and the tail end {in more ways than one} of Blue Steel {the rocket that was to carry our nuclear weapons}, launched from the Vulcan Bombers, worked on them too, plus the Lightning Fighters, shows how old I am, sigh...

The went orf to Canada in 82, working on F18's Blackhawks, Grumman A10 Tank Busters etc, but found myself going into "war" for almost 6 ferkin years, {do a Google on "Norburn Fleet", that should turn the saga up}... Them were the days, sigh, sued for 6 Million $'s {yea, they made me the 6 Million $ man}, put me through all sorts of hell for over 5 years, even planted 6 oz of plastique explosives on me car to get rid of me/shut me up, but us Wigin Lads don't let go once we've sunk our teeth in... Lucky for me the "device" was found by the RCMP, or I'd have been the first Wiginer to go into orbit...

Hell of a time though, near finishd me off, but I was luckier than at least 7 F18 pilots who lost their lives due to aircraft malfuctions, add to that 10 Blackhawks that crashed and killed around 52 people. I finished up being flown down to Washington {by the FBI} to meet with Casper Weinberger {Secretary of Defense in those days}, plus a whole host of Senators investigating why their aircraft were falling from the skies. The Senate Sub Committee that was investigating these events {and whom I met with} included... Barry Goldwater {the Chairman}, Senators Sam Nunn, Carl Levin, Teddy Kennedy and Neil Armstrong {imagine me, meeting all these guys} ! I finally won the day, but I carry some battle scars for it...

And I guess you are kidding me on that your SAAB has no gears?!?! If not, they sold you a dud and you aint goin' nowhere soon.:cry:

Grin, I think it might just have 2 gears, as it manages to go in reverse from time to time, grin...

PS: Maybe the fact that we were both Aero apprenticeships led us into SAABs. This is my 4th SAAB but is has been 20 years in between the last one and the one I own now.

At least it made me appreciate well designed and well built and safe modes of transport, few appreciate that more than I do...

I'm not sure whether you're saying this jokingly (or not - the smileys make it a tad difficult), but the SAAB 9-3 with 150 BHP and the automatic gearbox does indeed have 6 gears forward and one reverse. Just slap the stick from Drive (D-position, to the right) to Manual (M-position, to the left) and check the gear "number" on the Dash. Don't tell me it can't be done, I drive the same combo :) and I regularly switch from D to M (and back) for cornering.

Cheers,
BaRa

Hi,

I'm not sure whether you're saying this jokingly (or not - the smileys make it a tad difficult),

I'd better fess up, before someone mails me a dunce's cap, grin...

Yea, I know the car has 6+1 gears, it's just that I never use them, grin.

to Manual (M-position, to the left) and check the gear "number" on the Dash. Don't tell me it can't be done, I drive the same combo :) and I regularly switch from D to M (and back) for cornering.

Right ! understood, but at my age {57} I don't do any cornering anymore either, grin... Best cornering car I ever had though was a 1990 Acura Integra, went round the exit ramps like an F18. I guess the cars low centre of gravity {and mine too} and the double wish bones {the cars not mine} did the trick. After this exciting car I calmed down a lot, and went for more sedate vehicles like the Passat 8 cyl 4 litre, I never had the nerve to challenge what this car could do. Like a fool I once had 135 MPH out of it on a straight/quiet stretch of highway in New Brunswick, but at that speed my nerve ran out, with the pedal still begging for more, sigh... but I'm too old to be dafter than that now.

There's some in Canada that would like to see me pop me clogs, so I've no intention of doing it for them.

Hello Iain...

Just went to check out that Whistleblowers site {in Oz} that holds stories like mine, seems that they may have been shut down, certain folks have been trying to do that for quite a while, but...

If you do a Google search for "Norburn Fleet" you should get a listing showing...

"Blowing the Whistle by Dave Kewley"

The page won't open anymore it seems, but if you click on "cached" underneath the listing you should still be able to "read all about it".
