Well there's your problem right there. Changing the oil every 10-15k Is
about 3 times the recommended interval. Ah but your going to say "I used
synthectic". Doesn't matter. The reason to use synthetics is for the
lubrication properties and the resistance to breakdown, it still picks up
impurities and dirt just as fast as the traditional oils. You still need to
change your oil every 5K.

hi
everyone i know who has used synthetic oil in car motors has blown them
up

I used synthetic oil in my cars....and they have all quit....after
200,000+; 245,000; and 260,000 miles. I never had one make it to
300,000.....

They might have lasted longer if I would have done more than change
the oil....but door handle would come off...the plastic
cracks...sensors fail....the damn pieces of junk. The current car
only has 150,000 miles and the paint is peeling, dashboard cracked
from hot sun...and the radio doesn't work.

...of course I change the oil every 10-15K. But that doesn't help
with the dings, dents and abuse.

On the boat, however, I run a Perkins 4-107, and I just think the oil
should be changed far more frequently.

I'll change the oil in the boat at 50+ hours....I tend to not go over
too much.
