Replacement Generator

Randy, interesting story. However, I'm not confident that it is credible. If you
read Detroit
Diesel's service bulletin regarding their lube oil recommendations, they discuss
extended
drain intervals, as I recall in the context of using synthetic oils. In any
case, Detroit will
allow extended oil drain intervals IF SUPPORTED BY OIL SAMPLING. In addition,
several
years ago, I was aware of a test program in which Mobil Delvac 1, a multi-vis
oil and as
such not normally approved for the 92 Series engines, was used in a fleet of 92
Series
Detroit Diesels. Detroit and Mobil both relyed on oil sampling to judge whether
the Delvac
1 was suitable. The oil performed superbly, but Detroit never published approval
for it.

dodge
diesel truck,and he decided to send oil samples off instead of changing oil
every 3000
miles or so,so,he sends 3 samples off every time to 3 different places to get
them
analized,blackstone labs,cat and another one.all 3 came back everytime with
three
completely different reports,none of them were the same,not even close.this
thread went
on for years,up to 20,000 miles on the truck before the guy gave up.he said that
its way
better to change your oil and trust that the new oil was good rather than trust
the labs to
do it right and get you back the results from your oil,not someone else's..i
change my
oil.its way cheaper in the end,IMHO....randydupree93wb
