Thank you for the reply.
After research about
oil and the availability of
oil types here in Greece I will go with the Redline 40WT Race
Oil (15W40) or the 50WT Race Oil (15W50) . Both are 100%
synthetic Racing oils but since Jeniffer from PE was ok with using these (even with my 700miles) I believe that is ok.
Do you know if I need another / different oil filter because I will switch to
synthetic oil? At the moment I am using the Motocraft FL-300.
Also another similar oil that I can found here is the
AMSOIL Dominator 15W-50. What you guys think?
Thank you - Andronikos,
