| Re: What is the best synthetic oil? Best oil filter?
I'm a little confused here : Why do you suppose that GM does not
mention anything about changing the oil sooner on the CTS-V during normal driving on the street earlier than when the oil monitor suggests ( which usually is around 5000K plus) ? And GM does not suggest changing your fluids on the tranny and differential earlier than what they suggest- well beyond 10,000k .
Given that GM must cover the engine , tranny and differential for five years or 100,000 miles ( following their recommendation on the maintenance on these major components) , you would think they would be a little worried if these conponents especially on a high performance car such as a CTS-V , might fail prematurely if they needed attention alot sooner ?
Just curious if someone could explain the contradictions I'm reading on this board about changing oil and fluids please .
