    Can the wrong type of Motor oil cause a problem with a Turbo Charger?
    I recently had an oil change at a local quick oil change shop. After about an hour i started smelling burnt oil. I thought that they might have simply spilled a few drops during the change. I continued driving and went home. The next day when i started driving the ...

      Oh my gosh I just encountered this today! I have the exact same car and went to the local quick change auto place. They recommended their off-brand 5w30 oil, but I was nervous and broke out my manual just to be sure. I pulled out my oil specs and saw that it listed the 5w30 amoung others but that it kept reiterating the importance of meeting the GM-LL-A025 specification. I asked to see the bottle of the off-brand and they said they only had drums of it. They said they also offered Mobil 1 products that did come in bottles and I asked them to check those. The tech came back saying the only one of the suggested viscosities that listed GM-LL-A025 on the bottle (he then showed me the bottle with that spec on it) was the Mobil 1 0W-40. I opted to go with that one versus the off-brands or Mobil 1 5w30. However based on your post I checked out the Mobil 1 website and after putting in our car model was also told that Mobil did not make oil for my car in the US. But then when I looked up their specific 0W-49 European car formula it specifically said it was of the same quality as Saab. Now I don't know what to think... Really sorry to hear about the problems the Mobil 1 caused in your car :/ Hopefully at least our posts help keep others informed...

      Mobil 1 ESP 0W-40 is recommended for all types of modern automobile engines, especially the high-performance gasoline and diesel engines found in the latest passenger cars, SUVs and light vans.

      Mobil 1 ESP 0W-40 has the General Motors Service Fill dexos2™ approval, which is required for all 2010 new GM/Opel/Vauxhall/Chevrolet Diesel and Gasoline models. GM/Opel have advised that dexos2™ specification is backward compatible to older GM/Opel specifications (GM-LL-A-025 and GM-LL-B-025). The majority of GM/Opel/Vauxhall/Chevrolet Diesel and Gasoline vehicles can use dexos2™ lubricants.

      No wrong type of motor oil can not cause problem to turbo charger if it has the same viscosity level

    Occasional 'funky' acceleration; engine occasionally hard to turn over; possible slight exhaust smell; no codes
    This Sept. (2014) I bought a 2008 Saab 9-3 2.0T w/ 46,000 miles on it. It had been a lease when Saab was still in existence + had one owner after that, who garage-kept it. I bought it privately + had a mechanic give it a once over before I made an offer. Overall the ...

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance.

      This aspect is important; there may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Do not skip this important first step - there are literally hundreds of possible fault codes. Avoid wasting/ throwing money at the problem.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

    When I hit the turbo it makes a weird noise
    When I hit it and my turbo gets into the red zone on my meter it starts making a noise as if you were blowing air through a straw. Is this bad? How can I fix this? Is it possible that the turbo is bad? Or a bad bypass valve?

    Is my car worth saving? What's wrong with my car? Ballpark cost to fix problems listed in additional details?
    Ok. So I have a 2003 saab 9-3 turbo. At stop signs and lights, the RPMs rev from 600-900 RPMs. After driving for a bit, the revving will stop, however, There is a 5 second delay from that point on, from pressing on the accelerator to actually picking up speed. ...

      For replacement parts, check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few.

      Please post a reply with the specific codes for further assistance. Too many possible components for each code or description to possibly provide any cost estimates.

      For example, the code P0300 = Random Cylinder Misfire
      For the misfires

      It may mean that one or more of the following has happened:

      Faulty spark plug or wire
      Faulty coil (pack)
      Faulty oxygen sensor(s)
      Faulty fuel injector
      Burned exhaust valve
      Faulty catalytic converter(s)
      Running out of fuel
      Poor compression
      Defective computer
      Possible Solutions

      If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

      If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

      hello jimm. i went to autozone this morning they checked for codes and they found none.
      2nd step i added sheel v-power to the tank not sure if it really cleans the injection or should i add an alternative product? 3rd step air filter is clean gonna do the 4th step fuel filter.
    • Jimm
      3/16/2015 Jimm
      Start with the easiest and least expense - clean (use a MAF-specific spray) the air intake and replace the air intake filter. Next, inspect the engine for any vacuum leaks / cracked vacuum hoses.

      How many miles / time since the fuel filter was last changed? Try these simple and inexpensive steps first, then report the results.

      i went to a saab dealer they have checked the history of the car everything and everything is fine they reset the computer and i added shell v power gas twice and drove over 200 miles no more vibration the 1st owner always kept the car up to date but the second owner (the kid) did too but i guess he got tired of putting money into the car and i also think he was putting cheap gas all i have to fix now is shocks and radio. thank you.

    How much does it cost to repair or replace the turbo?
    I had white smoke come out of the exhaust, and I smell burning oil inside the car when I turn the heat on, is this related to the turbo
     
    • Jimm
      3/14/2015 Jimm
      Have an inexpensive compression test performed, as well as a cylinder leakdown test to determine the specific issue before condemning the turbocharger.

      If a new / rebuilt turbocharger is needed; check these sources; www.saabperformanceparts.com, www.turbochargerpros.com, www.saabcentral.com - to list only a few sources.

      You can also buy a rebuilt kit vavailable separately- depending on the extent of the repairs needed - to save some of the cost.

    Why does my car leak coolant and would it be costly to repair.
    My car has 252,000 miles and after having the engine oil changed, in the past 2 weeks the coolant has been leaking excessively. Each morning I have been adding coolant. I filled up the reservoir tank drove about 20 miles and the tank was empty. The leak is in the ...

      Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.

      Make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating.

      1. Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

      2. Air pockets trapped in the cooling system can cause the engine to overheat. Some cooling systems have air bleed valves built into the system to aid in the removal of air pockets. Advice: For many cooling systems, the method of removing air pockets is to start the engine and allow it to run with the radiator cap off or loose until all the air escapes from the neck of the radiator. For some systems this method is not sufficient, and the manufacturer has installed air bleed valves usually near or on the thermostat housing.

      You may hear a ticking noise from the lifters on starting up from cold, but this is quite normal on the higher mileage cars. But if it is happening very often, you may change the bad one.

    Will the engine run with the turbo disconnected, and would the computer need to be changed.?
    This is a general question for any turbo charged Saab mainly for the 1993 - 1998 models. I dont like the extra fuel cost of running the turbo models, looking for a way out and removing the turbo. Lots of engines have turbos added to them, so can it also be removed.?
