hi guys,

my 9-5 seems to have used a fair amount of oil in the last 3 weeks ..
3 weeks ago I had a b235 fitted in place of an oil starved b205, done by my local garage, mark9000parts supplied engine and he did sump drop before selling it me, so all was good.
engine was fit with all new gaskets,latest pcv kit , 5e-40 full synth oil , all supplied by neos. I had noticed an oily smell in the car around last week, when I went to saabnoobs for a remap he noticed the smell too.. I've searched high and low can't see any leaks, when the engine was fit 3 weeks ago, dipstick was at max, i checked yesterday morning its on min ! seems a lot to use ? turbo is a mint td04 no play at all and never get any blue /grey smoke , baffled ! help !

Have a real good look underneath with the car on a ramp or jacked (+ supported on axle stands). Someone once brought a 9-5 round to see me that had an oily smell but when I asked the car's history was told the sump had just been taken off and a new PCV kit fitted (excellent). Only problem was... the return pipe from the separator was not pushed onto the sump... allowing oil to be blown under the car. The oil level was not down enormously, so no damage was done.

Check the top of the cat - oil leaking onto the cat can be burned off. This scenario on a 9-5 could mean the rear crank oil seal is leaking BUT the easy check for this is to take an 11mm spanner to the x2 screws that hold on the half moon shaped flywheel cover on -oil inside = bad news, as rectiftying would mean a box out job.

Oil pressure sensor at back of engine is a common leaky point, it allows oil to seep down back of engine, on to exhaust and burn off - could be the culprit? Cheap fix too, just a little fiddly.

Take the splash guard off underneath then tell us if there are any oil leaks as there are too many things it could be without you having a look. Sounds like a lot of oil loss so have a good look at oil cooler at front underneath as well as all the above.

Oh and don't drive it with not enough oil in, sounds obvious, but we all get tempted to do it. Hope it can be sorted cheaply.

You don't say how many miles you have driven, Lee.
I expect my 9-5 to use at least a litre in three weeks (which at the minute represents about 1800 miles for me). The newer SAAB engines (B2x5) use more oil than the older ones as the tolerances are a little bit more open. As a comparison I got a bit worried when the T16S started needing ½litre between changes! The 9000 at 225 000 miles doesn't use any oil between changes either (although it has been off the road for a couple of years )
SWMBO's Corsa by comparison (R- plate 24 000 miles) has it printed in the manual that it will use (and here I can't actually remember) either 500ml or 1 litre every 900 (yep, hundred, ) miles

lee just check over what the guys above have said as i only had to top that engine up once in the 6 months i drove it.

only done around 400 miles at most guys , just had a good poke about with Phil (filathome ) and we found a leak ! its dripping from the back area of the engine onto the hot exhaust below ! will get to the bottom of it Saturday

Yay! leaks are relatively cheap to fix (as opposed to worn bores!) sounds like the pressure switch then (and a canny leak by the sound of it!)

quite pleased ! we popped the bonnet after a good thrash and found smoke coming from the rear of the engine, I popped my head underneath to see the exhaust sizzling oil will get it up on some ramps sat to further investigate, cheers for all the replys guys

oil leak found and cured ! finally a break in our horrible weather allowed me to get it up in the air and get under it ! after all the worry turned out to be 3 missing sump bolts and most others loose ! tightened them and replaced missing ones and the leak has stopped ! yipee ! I love simple fixes like that

my 9-3 aero's B205 uses about 500ml every 1000 miles no smoke or leaks, thats on 5w-40 mobil super 3000 fully synth, topped up with either the same oil, castrol magnatec or castrol edge 5w-40 depending on whats in the boot at the time.

my BMW used to use at least a litre every 1000 miles, newer engines use oil..

ALL engines use oil to a certain degree, it's impossible not to, the cylinders need a certain amount of lubrication some of which is obviously burned off, and some oil is lost through the breather system and burned off. I'm very sceptical when people say "my car doesnt use a drop" the level in the sump may read the same but what's actually in the sump will have changed.. a proper oil test will reveal a certain abount of water, fuel, dissolved solids and solids in suspension

I'd be worried if I didnt need to top up my oil.

My B2x2/4 engines never needed topping up, which is not to say they didn't use oil, the level dropped but not down to the min level, whereas the B2x5 engine in the 9-5 can drop below the dipstick

With the B202/4s as long as the level was within limits I just monitored it, <½ litre after 6 000 miles wasn't excessive.



Hmm, emission friendly...

The tighter the tolerances on an engine, the less oil it should use. The tighter the tolerances, the more it costs to make....

No brainer for motor manufacturers and Big Oil then...

I never noticed much oil consumption on my ng900 or 9000 but I'm sure there was a little, gonna keep a close eye on this b235 , just got no confidence in these engines

I have the same problem on my 95. Bought it 2 months ago. had MOT done this week and there was virtually no oil in engine. Now it is topped up it smokes from engine and exhuast at startup and higher revs. Turbo was new so hope thats not the problem. MOT garage said the pipe going into sump is probably blocked. Needs the sump dropped and cleaned I think. Common problem with SAABs apparently. Getting it looked at next week. Getting some good use out of the warranty!!!! Garage I bought it from were useless so taking it elsewhere, but still love the car! Being half swedish I feel complete now!

Maybe consider cleaning sump if you havnt tried that. Think I proibably need more advice than you?
