H i ,
I have recently Bought a Saab 93 1.9 tid 120 estate 2008 with 108,000 miles on .
i was expecting 40 to 60 mpg but am only getting 26/30 local and 40/45 on a run
can anyone suggest what the problem could be? is it just needing a service?
last service was at 90,000 with a cambelt change.

Hi,
How are you getting the figures you quoted?
Are you using the car computer or by filling the tank and recording your milage?

Hi, ive got a 150bhp and local im getting 38-40mpg and on a 79-80mph motorway run about 48-50mpg, mines done 138,000 and its 2006, I have it serviced regular and ive got a maptun airfilter, im tempted to get the dpf removed.

Perhaps we should start a mpg subject?

Is it a manual or auto?

My 1.9 150 auto is currently only doing 37-38mpg on motorway runs, I'm hoping replacing my knackered inlet manifold is going to improve that very soon!

hi guys, hope i can help a little here.
Firstly if the car has not been serviced reently, then do it.
The egr valve should be periodically removed and cleaned.
I advise my customers to try a can of BG244 in the fuel tank to help clean the entire fuel system. So far all that have tried it, have reported benefits from using this product but please judge for yourself. I'm not affiliated with the company, it's just a product I've found that seems to work.
Next is to buy a can of air mass meter cleaner and obviously clean the air mass meter. (follow instructions for use!)
Check tyre pressures.
And if you have your vehicle serviced by a technician get him to check that your thermostat is functioning correctly, do not just go by what the gauge on the dash says.
I know it seems alot but it really is good maintenance and it SHOULD restore MPG to what it should be.

I was told if your tyres are too low, you might as well be towing a caravan!, i check mine very couple of weeks but I do clock up 600miles a week, plus the added fact of lumpy ride and bush damage too,

Thats nearly 20K between servicing if I read that correct?

So - for me thats too long... 10K max for a service...

Use the correct 5w30 Dexos2 oil only
Change the diesel filter
Check the engine is running up to temprature and staying there. These stats fail open maning that the engine runs cold
Decent air filter and ensure that the air meter is clear and clean
Whats your coolant condition like? if not correct - flush and change
4 wheels off the ground and check bearings, suspension, and brake calipers for sticking
Check air pipes for splits or leaks
etc..

Hi
Thanks for all your comments,the car is a six speed manual by the way and I think the first thing is I will get it serviced as it is ready for one anyway. one question is the egr valve cleaned as part of the service?
also thanks about other tips on tyres etc.
where do you get the following and has nayone else used this and found a benifit.

I advise my customers to try a can of BG244 in the fuel tank to help clean the entire fuel system. So far all that have tried it, have reported benefits
thanks all for your help

A quality oil and quality filter change every 6 months works out at the just under a pound a week,(if you can do yourself) this could save you a lot of money,

It will be mate. Due to the inlet you are driving the car harder to make it do anything...

Fresh inlet - and also make sure you get that PCR valve cleaned too :)

The Z19DTH is not the most eco diesel... thats for sure. When I take our vec on a run to work which is a mix of stop start, dual carridge way and one motorway junction, I will only get mid 30's with my driving style.
