[DML] oil discussion

[M5E <nitrousgarageworks@xxxxxxxxx>]

  I've pretty much settled on 5W30 as being my oil of
choice:
A hotrod magazine article reported the largest
horsepower gain using that grade of oil

Using a super-grade synthetic, like Amsoil should lay
to rest any concerns about adequate flow, and
lubrication, or breakdown of the oil.

I've used the Amsoil motor oil in all my vehicles,
from V-8's to 4 cyl. Porsche engines, and have
"enjoyed" the extended drain intervals.

On drain intervals: Amsoil says their product can go
25,000 mithout a change. Supposedly at 12,500 miles
you should change the filter, and add a quart. But I
just opt for changing the oil and filter at 10,000
miles- period. Even doing that keeps the costs in line
with other brands of oil, and I still get to enjoy the
superior components of the synthetic product.

Some time back I asked AMsoil about mixing grades of
oil. Example adding a quart of 20W50 to my usual 5W30
to "stiffen" it, and asking would the grade then
change from 5W30 to 5W50? They (Amsoil) advised that
it would be like mixing golf balls, and base balls.
The properties of the 2 grades of oils would not mix,
and they recommended against it.

I can report though I have had no problems what so
ever with using the 5W30, even in a 4 cylinder high
performance engine.
