'84 Saab 900i: Motor oil choice
Quick question, can I use this kind of Bardahl oil for my Saab? (Second image is the car's service manual, tell me if you need translation).
Currently I'm using Shell Helix 10w-30 full synthetic oil to flush the freshly rebuilt engine and for the break in, because it's cheep.
At the third oil change (1000 Km) I wanted to switch to Bardahl 10w-40, but honestly I don't understand any of that API SN SF stuff so idk if it'll be good for the engine on the long term.
Please help, thanks!
