Hi all!
My grandfather has a 2002 Cadillac Deville with 53,500 Mi on it.
Ever since he bought it new I have changed the oil&filter in it for him.
He always buys the oil, but its just regular 10w-30, not synthetic.
I have told him over and over that the synthetic oil would be better for it, and probally make it last longer.
Since he's old (79) and very old-fashioned, he says that synthetic oil is "the worst oil you can use. It's not even real oil."
So, I guess it will have regular 10w-30 oil, and an AC-Delco filter in it for life.
We change it every 3,500 Mi or so, and I was just wondering if it will really matter to the life of the engine in the long run.
Thanks,
Talker
