Synthetic vs. Dino

[Mike Hohnstein]

Thanks for your insight. How many miles traveled are you basing your report?
In other words, how many miles accumulated since the oil change?

From the for what it's worth department.

After speaking with one of the members of this forum about the value
of synthetic versus dino oil (thanks Bob) for my 1993 8V92 I made
the switch from straight Rotella 40W to Amsoil 15W40. The results
have been nothing short of amazing as oil consumption went from
around 1 quart per 250 miles to about 1 quart per 850 miles when I
am pushing it hard, to pretty much nothing when driving 55 or 60
MPH. The 40W used to get that diesel black color within a couple
hundred miles of an oil change whereas the synthetic oil is still
quite clear even after 3200 miles. The engine used to smoke some
when leaving a stop light but now has to be fully floored to put out
much smoke at all. The coolant is also not running quite as warm
thus the fan is seldom kicking in any more. More than likely fuel
consumption has also decreased but since I do not keep track I can't
vouch for that. It is quite obvious to me that something good has
taken place with my change from dino oil to synthetic. Next step is
to change the other lubricants as well. I am not trying to start a
war here but am just relaying my experience "for what it's worth".
