Milwaukee to Lewiston ID on I-90 to Missoula MT to US 12 over the divide to
Lewiston.
A great route, very scenic and no bad grades. Bought some land out there and
set up a pull through site with all the amenities.
Did PM to the truck for the several trips I need to take before the snow flies
after words did a couple of short trips. Lost a small hose in the coolant
system 75 miles from the house, needed a 1/8" pipe plug to fix that. Real
problem was the Dello Mobil 15/40. Used 3 qts. in 400 miles, did much better on
Rotella. Called Dupree and cried, he made some suggestions. I went with 30
straight weight and a couple of cans of STP and headed west.
It was real hot and I kept the speed at 60 mph. Started out using direct @ 2000
rpm, 195 coolant and oil sump temp. After a while I went to OD and tried
keeping the engine down to 1600 rpm. Oil temp went down to 150, that caught my
attention as it was damn near that hot on the road surface.
Cat sez to keep engine speed down as it will save fuel, it's the truth. I was
at 38k gvw and averaged over 8 mpg, and my toter is not as aerodynamic as a bus.
The real deal was I used only one qt. of oil in 3400 miles. On the return trip
I got a little impatient and picked up the pace, mileage dropped as speed picked
up. Worst was 7 on the last leg running 70 @ 1900 into a serious head wind.
Back in the day, I always was a straight weight guy, I guess after this
experience I still am. Heck with that multi weight stuff, it don't get it as
far as I'm concerned. I used tractor oil bought at a Fleet Farm store, it was a
good price too.
I need to get that 10 speed in my FC.

Hello Mike,
Don't want to get thread started on the subject of what oil to use but I use
Rotella 20W-40
and didn't have to add any on round trip from SAT to Ouray (about 3000 miles)
running at
60-65 mph. I've noticed that if I fill the engine to full mark on the dipstick
it will quickly
blow out or consume oil down about 1/2 to 2/3 of the way to the "add" mark on
the
dipstick. After that, the oil consumption is nil. All that said, you may want
to watch where
you carry your oil level as it may save you some money to control it a little
lower.

Before I retired in 2000, I made lube oil for Pennzoil and Conoco for a few
years and saw a
lot of engine tests and other lube research in the process. As for STP, I don't
recommend
it for car or coach. A lot of work done out there on any good quality oil to
get the right
balance of vicosity and lubricity for a given application. The average Joe
doesn't have
enough information to start modifying a lube blend.

Eric Johnson,
Allow me to impose on your knowledge.
Can you tell me what you think is the best
oil for a 1986 Detroit Diesel 8V92TA, 475hp. engine.

Hello Howard,
I'm no expert on specific engine applications. My recommendation would be to
use the
weight and type recommended by the engine manufacturer. I noticed that Harvey
Lawrence has a document about lube oil in the "Files" section. In that article
he says you
should only use a single weight oil in a Detroit Diesel due to the type of
engine it is. I
assume he based that on manufacturer recommendation. Harvey also makes some
excellent points about the formulation and function of lube oil in his article.

Mike:
When I was driving thru the hills of Kentucky and West Virginia and
had the problems with my crossover pipe I noticed a direct correlation
between exhaust gas temperatures and oil consumption. Prior to the
exhaust repair, I was running EGT's at the high end of 1100-1200 amd
after the fix high was only 900 and that was very infrequent. I was
using oil before the fix and consumption dropped to almost zero after
the exhaust repair. I have Rotella Synthetic in it.

Yeah, well what ever. Multi weight oils are a marketing tool used to appeal to
those who don't like to think about technical issues. Them engineers who make
the stuff have a point of view but my laboratory is my road use and what the dip
stick sez. That's real world experience, at least in my world.
I would get 1000 miles out of Rotella before it would start to go away on level,
the Dello didn't come close to that and we are talking 55 gallon drum supply,
not bulk.
My engine has 60k miles on a out of frame major overhaul and 3 ring conversion
was done as was the roller cam update.
Those who aren't satisfied with oil consumption in their personal units might
consider the change to straight weight.
Keep in mind, warm up times are increased a little and one has to be mindful of
the time of year.
As for my drum of Dello, we will attempt to foist it on our many diesel pick up
customers, I'm going back to the old ways.

If you want a lot of info and comments on the Detroit Diesel engine, you
should also join the MCI bus nut forum. Gosh they had lots to say LOL, and lot
of info as well

Howard, there is a very good technical article on oil recommendations on
Detroit Diesel's web site. You'll have to look for it as I have lost the
specific link but I would highly recommend that all DD folks download, read
and save it.
