Still lost with term OEM for oil? Is it ford branded
There are lots of oils with correct spec, but we all have our own preferences. Same with choice of partner /cloths/ polish ect ect, one will swear by it one another will say rubbish. Some will say change oil twice a yr with good oil is better than once a yr with the best oil money can buy.
Personally with a £30k + car I’ve got no problem with buying castrol for it, if you want to save £25 on 10ltrs go for it👍 works out to £0.001 per mile saving if it was enough for 2 services, I know it isn’t( going by fords service requirements of oil change every 12,500 miles)
