I used 5 W 40 fully synth over the years in my FTO's - however now they are all getting a bit older I'd be more inclined to run a 10W 40. Buy one of the better brands if you can - oilman on here regularly runs promotions for fuchs/silkolene etc which IMO is a step above Mobil 1 / Castrol edge etc (either of which are still absolutely fine btw).
