Salam,
Guys I have Exi 2005 MT. I use Caltex Formula oil which comes in 4 liters, as car has capacity of 3.2 liters therefore, remaining oil I always keep with me. Now I have saved almost 3.5 liters of oil from every oil change. My question is that can I use this oil for my car or its not advised to use?
Regards,
