Hello All,
My first oil change will be coming up on my new(certified used) kia forte it will have about 14000 miles on it by then. The car is driven on the high way at 70-80mph speeds primarily with little stop and go by my wife, on the weekends I drive the car, and sometimes I like a bit of a spirited run on curvy roads 5-6k rpm shifting max(only after it has had a chance to warm up).
In my manual it states i can use anything from 5w20-10w30. So I am at a loss, I have always used 5w30/10w30 in the past with decent results(gm vehicles), although all of my cars have ended up burning oil.
I want to ensure a long life for my car, and hopefully keep it from ever being a oil burner(currently it doesn't lose a drop as far as the eye can see). I have a choice to make about wither I will run a 5w20 oil or a 5w30 oil. I have read tons of things about this topic and I am still at a loss. Some people seem to think 5w20 is only for CAFE requirements, and that it offers less protection than a modern 5w30. Others say a 5w30 will shear out of grade down to a 5w20.
I was curious as to if there is any hard evidence either way to help in making my decision. Currently I am determined to use Pennzoil conventional and follow the severe schedule for my car until it is out of warranty (3750 mile oci) all thats left is to chose the grade.
So please let me know your opinions, they are always appreciated and if you have a link or info to any hard general evidence I would love to see it.
Thanks!
