7500 miles isn't so far really - modern oils are a lot better than the
stuff we used to use in the 60's and 70's and the quality of the
engines is a lot higher - better machining - plateau hones bores etc-
so a lot less wear and swarf left in the engine.
I do have problems with some makes who now specify 16000 mile oil
changes - this is purely based on lowering the costs of ownership to
the fleet buyers who will get shot of the car at 80k so don't care if
it's worn out at 85k.
I've only ever tried Slick50 twice - one occasion it made no difference
at all, and on the other the engine siezed up the next day.
My Pan European (Honda 1100 bike) is now on 75k and is still like new
on just oil and filter changes every 4000 miles. Rangey on 145k with
the same regime and still doesn't burn any oil or rattle.
Good clean oil and filters and don't waste money on additives is my
views.
