I'm 1000 miles into my very first use of Havoline in my 2000 Dodge Grand Caravan.
Before this I'v used Castrol and Valvoline only.
I have noticed that the Havoline turns darker sooner than the Castrol did. Is this due to the increased additives that Havoline uses and because it may be cleaning more than the Castrol did.?
