Adding oil when Castrol TWS 10w-60 is not available
Needed to add a quart last night and of course 10w-60 is not readily available.
Stopped by a walmart which was the only place open and the options were:
Castrol Edge w/Titanium 5W30 (gold bottle)
Castrol Edge w/Syntec 5W30
Mobil 1 0W40
Mobil 1 High Mileage 5W30
Ended up with the gold bottle of Castrol Edge as I've read it's the same as TWS.
Anything negative from using a different weight? And any tips on what oil to use when OEM or 10W60 is not available?
