Engine oil grade for Mk3 Mondeo Zetec
New Boy here.
Sorry if this has been raised a thousand times, I have searched the forums but I,m still not sure.
Just taken ownership of a nearly new 2.0 Zetec Mondeo Mk 3 (wow these cars have improved over the years!) The stated grade of engine oil is 5/30, 10/30?
I have 20+ litres of 5/40 fully synth left over from my SAAB days. Can I use it or will the Wroth of the Gods of Dagenham reek havoc upon mine engine?
Thanks for any advice.
