Did an oil change on the IS-F today. Car was running Amsoil Signature, but NOT an Amsoil filter. Appears to be a K&N oil filter. Drain interval is 8,000. This oil has 16,000 on it. I took a sample to be sent off to the new(ish) testing facility in Edmonton. Should have results in a week or so...maybe longer due to holiday backlog. Will share results.
Amsoil Signature back in with Amsoil synthetic filter.
Also put in my JDM yellow fog lights.
