On top of the engine on the drivers side there is a black plastic cap, with a large plastic nut looking thing. Take that off and you will find the filter.
go to auto parts store and get the right filter for the Saturn then go to the filter wrench selection and find one that fits that is the style you like

I have a 4 cylinder and I just bought a fram CH9018.
Depends on the engine size 4 or 6 Cylinder?
fram PH6607 or equivalent
On a 2008 Saturn Vue , you don't mention the engine size , but the 2.4 liter four cylinder uses a timing CHAIN ( also the V6 )
the size of saturn is as big as my pinky
36mm
If it is the 4cylinder 4x4 then the tires are either 225/75/r15, or 31x10.50xr15
According to the 2008 Mercury Sable owners manual : ( the Motorcraft FL-400-SB12 engine oil filter is used for the 3.5L V6 engine )
Probably the same size -- 17 mm -- as for the 2006 Vue, if it's the 3.5 L V-6 engine.
Use a Quality Filter WIX # 51348. Also when changing the filter's make sure the old filter gasket comes off with the filter and is not stuck to the engine block.
