Any product made for the African market is usually not up to international standards... so that been said I don't know much about coastal oil ,but if it is Castrol and it is made in USA go for it.. Even some of the so call oil that are made in the USA ,are up to standard ..but other brand like Castrol USA made or Mobil 1 exceed the USA standard.. Always go for the brand names. They have a name and reputation to protect..
By the way, am team Mobil 1

Thanks boss but how do you know if it's a US spec not Africa Spec incase

milemaster isn't bad at all.its full synthetic and I used it some years back on my golf4 V5 engine.....but iv not seen it in the market for a while now

coastal is semi synthetic.....it's what I use right now...but my oga on here doesn't like it one bit.and so I won't recommend it

Yankee coastal full synthetic magnatec is equally superb..... I've used it on our personal Volvo XC90 with the SI6 engine and the S60 2.0T engine variants and they have performed excellently well

that's the personal summary on these engines

ultimately the decision to use whichever oil is urs to make
