Well I just picked up an 04' SAAB 9-3 with only 149K KMs. The previous owner took very good care of it and ran it with Castrol Syntec 5w-30. The car is in need of an oil change and after curiously looking through many web posts for oil requirements on this car I'm now quite confused. In the owners manual it states that it needs a synthetic oil that meets the GM-LL-A-25 (now Dexros1) specs in the viscosity range of 0w-30, 5w-30, or 0w-40. (apparently 5w-40 was added later)
Every SAAB forum I visit a lot of owners are using Mobil1 0w-40. I know 0w-40 is good for cold temperatures , but how does it work in the hot summer months? I live in Eastern Canada where the summer months are hot and humid (high 30's to low 40's C) to really cold (below -10C). I want to know if Mobil1 0w-40 is the my best option for this type of turbo engine and the climate I'm living in? Another option that I was looking at was Motul X-Cess 5w-40 (GM-LL-A-25 Cert). There is a performance shop near me that is liquidating their stock of Motul motor oils, and at the price they're selling it at its about the same as buying Mobil1, Castrol, or Pennzoil Platinum. I'm also not one to do long OCI's. I change my oil about every 7000 to 10000KMS.
My options so far:
Mobil1 0w-40 or 5w-30
Pennzoil Platinum 5w-30
Pennzoil Ultra Euro 5w-40
AMSOIL 5w-40 or 5w-30
Motul X-Cess 5w-40 or X-CLean / X-Cess 5w-30
What do you think guys?
Thanks.
