all the chart is showing is different grade oil tempertures.
but they dont recommend a 15w-40 and is it mineral oil you got
In the old days when I shopped a local ford garage, they had 20w50 for pinto's and 15w40 for diesels (mineral) (and poss' valvers), I'm not sure if I recall a fully synth, quite possibly, but doubt it was 5w30 and less than 40 quid a gallon!
It makes me laugh on here that a lot of folks would piss in a radiator rather than buy antifreeze at a tenner, yet they're all willing to buy the magic 5w30 fully synth for the old mk5's.... don't forget it not just a gallon!!... like they keep saying on public radio... 'other oils are available'
5w30 was 'made' for zetec engines, narrow oil ways and hydraulic tappets....
