Regular or Synthetic?

opinions as to what type of oil to run. With 80k, some say stay with
petroleum, but others say it's not too late to start w/synthetic. Any
opinions out there. Also any other knowledge concerning this vehicle would
be helpful.

80k mi must have been primarily highway miles.
If you want to keep this truck for the long term than synthetics are
the way to go. If you're the type to trade in the truck in a few years
than just stick with DDJ. (dead dinasour juice)

Go with the Synthetics. I use Amsoil in all my vehicles.

dead dinosaur juice. I doubt it will go much further using 12 quarts of
synthetic each change. Lots of guys change oil and filter at 6000
For other info go to turbodieselregistry.com

I switch all my vehicles to synthetic. I had vehicles with over 100,000 miles
but still switched. The older ( high mileage) motors never developed much
improvements but they did last up to 200,000+, start easier and ran cooler. I
use amsoil synthetics in motor oil, trans and pumpkins.
I became a believer in synthetics when I had a one ton truck pulling heavy
loads. The rear end cover would get hot enough that I could not keep my hand
on it, a friend talked me into switching the lube to amsoil and the heat went
away.
I also have a 850cc motorcycle with 56,000 miles with no motor repairs what so
ever.
I am told that if your application has an oil leak, get it fixed first because
synthetic oil will leak worst. I do not know if this statement is true.
Hope this helps.

general) require oil that meets certain requirements, requirements that
are different than what gas engines require. I'm an avid Mobil 1
user, but Mobil 1 is not suitable for the Cummins even if you can get
15w40. The Mobil synthetic oil suitable for the Cummins is called Delvac
1.
AMSOil 15w40 synthetic diesel oil meets the requirement, which is an API
CH-4 rating, however these oils are not API Certified.
Without certification there is no guarantee that the oil really does meet
the standards.
Can't find any info on Pennzoil or Castrol oils, Valvoline synthetic
doesn't meet the requirements...
I went through the same debate when I got my '97 2500 with the Cummins,
the final result was that I'm going to stick with Delo 400 even though I
love synthetic oils and have seen how well they work, the bottomline is
that there are very few synthetic oils suitable for use in our engines,
the synthetics that are suitable are a LOT more expensive than a good
quality diesel oil like Chevron Delo 400 or Shell Rotella T. Shell also
makes a synthetic blend called Rotella SB, but I'm not sure on the cost,
actual % of synthetic, or anything like that.
The average cost for a gallon of Delvac 1 is $20. Our engines hold 3
gallons, so that's $60 in oil alone.
The choice of oil is up to you, just make *sure* it meets the requirements
outlined in your owners manual, which will probably tell you 15w40 with a
CH-4 (maybe CG-4, not sure. For me it's CF-4) API service rating.
If you haven't found it already, a great website for Dodge/Cummins owners
is http://www.turbodieselregister.com/, I recommend going there as soon as
you're done reading this!

80,000 is not even a third of the way to your first rebuild, so
there is no problem changing to a synthetic oil. It might be a good idea to
use an engine flush just prior to the change to ensure a clean engine
interior. Expect 2-5% improvement in fuel economy, easier winter
starts(your battery will like this), and a somewhat cooler running engine.
Go with a known brand. I carry Amsoil products and can give you more
detailed info if you would like: best1s...@usadatanet.net .

You have an engine which can realistically go 400,000 miles with the
"alledged" dead dinosaur juice. I doubt it will go much further using 12
quarts of synthetic each change. Lots of guys change oil and filter at
6000 For other info go to turbodieselregistry.com
The Detroit Series 60 record is 1.6 million with Mobil Delvac 1300
conventional Oil.
The Detroit Series 60 record with Amsoil Synthetic is 2.1 million.
Both these engines ran Gulf Coast Bypass filters with very rare oil
changes, only when oil analysis recommended a change. I think around
every 75,000 ml with conventional oil and every 250,000 ml with Amsoil.
Changing the Element in the Gulf States Filter results in a fresh gallon
or so of oil being added every 6,000 ml or so. I think the primary
filters are changed around 60,000 ml.
