Looking at a '90 Volvo 740 Turbo Intercooled (2.3L B230FT) automatic for a friend of mine. The AMSOIL application guide calls for a 30-wt, but I think I'd recommend a good "euro" 40-wt in this case. Does anyone with Volvo experience know if these engines like thicker or thinner oil? I know the Saab demands thicker oil. This car will do a dose of ARX, and has a rebuilt turbo and new lines, if it matters...and 155K on the clock. No word on internal cleanliness, but previous owner was religious with 3K mi OCI's.
Thanks,
