engine oil on audi a4 cabriolet
You can't default to buying an "SJ" oil when it hasn't been produced for some time
The API standards change often and that's part of the reason VAG has developed their own lube oil specs...they're far more specific than a generic API recommendation. I think the VAG 502.00 standard has probably been around since the mid '90s and it's still the primary recommendation for the gas-engined cars today.
