Are you changing your oil too many times ?

I think the 3 month or 3K miles thing is a myth generated by
the oil industry to make us buy more oil.

I change the oil on my daily driver (Nissan pu) about once a year, weather it needs it or not...lol.
Been driving this truck for 13 years and its still going strong. Did the same thing with the Nissan truck I had before this one, over 13 years on that one and still ran great when I sold it.
I go about a year on my Dart too, but I only drive it a couple thousand miles a year.
