Don't use nulon's, i used there's cause it came in a 6ltr bottle and my engine rattled its head off, this was after i'd always used castrol magnatec, switched back to castrol magnatec and all good, only use magnatec in every car i work on, use it in the ls1 and have used castrol edge 5-30 in the ls1 currently using the magnatec and as i said not as loud now.
Hey guy, my Vy calais has 148k. I travel a lot of freeway k's, which has burnt the oil quickly. My dealership placed castrol magnatec 10w-40 in it and it's done 7k km. I purchased castrol modern engine oil recently with 5w-30 in a 5l bottle. Will that be enough oil for the engine with new filter? I'm hoping to change it today
