Question 3rd Generation 5.9L.: Synthetic Oil Change Frequency??

Newbie question. I am thinking about switching to synthetic oil at the next oil change. What is the maximum oil change frequency in miles recommended for synthetic oil? Does it require a different oil filter??

Question: how many miles per month do you put on the truck?

i use shell rotella 15w40 dino oil, and mopar filters, I change the oil at 7.5K miles, fuel filters at 15K.
It takes me normally 6-7 months to get those 7.5K miles, with synthetic oil you should be able to go 10K-12.5K miles between changes.

I just would not want to keep the oil in my truck that long, I want to get that dirt, moisture and other bad stuff out of the motor.

synthetic oil is great and is the oil it use:
if the truck has to be on the road making money, you are putting a lot of miles on it fast and you do not want down the least amount of time for general maintenance.

otherwise, i want the oil changed more frequently,
plus the cost to use high dollar synthetic oil and pour it out at 7.5K intervals.
about twice the cost of shell rotella 15w40

Just my two cents:

in my old truck the oil is jet black in 10 mins after changing the oil and filter.

Research has shown that conventional oil hasn't even broken down at 10,000 miles. Which would mean that synthetic oil hasn't even began to break down at 10k. I use synthetic and run my oil for 15-20k depending on the texture and smell. I replace my filter between 7-10k. The whole reason we use filters is to keep the nasty stuff out of our sump. This is just my personal practice, and it has served me well thus far. Although it does go against everything that we have ever been taught about our mechanical values.

I run 0w-40 Duron-E with ELF7349, previous was 5w-40 Rotella T6 with Baldwin 7977. Had oil sampled at 6500km(4000mi), said to still run it but I changed anyways. I have 5000km on the 0w and have taken another oil sample and will send it in a run the oil if they say to.

I think I am going to start running 10,000km oil changes OR 200hr intervals

Whether you use conventional or synthetic the filter is the same. The different types of oil don't make a difference to the filter.

i run 0-40 full syn all year long
change at 5000 miles
and air dog filters at 10,000 miles.
draining water filter in between whenever i feel like it. depends on weather/driving distances.
treat with 8oz stanadyne EVERY tank.

I've always been one to change my oil often
oil is cheap
although it does cost me just over $100 every change.
it cheaper than a rebuild

my supercharged bonneville
gets new oil every 5000 KM (3000 miles)
mobil 1 5-30 full syn
fuel filter twice to 3 times a year.

truck has 230,000 miles
car has 230,000 KMS
both run like a top.

both "go pedals" have a good relationship with the firewall.

no, youre not understanding what cummins is trying to tell you. when they say the LF16035 is synthetic they mean the filtering media inside the filter is synthetic material, not paper like in the cheaper filter.it has nothing to do with the kind of oil you run thru it.

Everybody should change their oil when THEY feel it needs to be changed, whether that's 3000 miles or 15000. BUT, changing out a high quality synthetic oil before at least 7500 miles (in normal running conditions) is a serious WASTE of money. Hundreds of oil analysis reports over the years have shown that. Have one run on your oil after 5000 miles to see for yourself.

Now, people will come in here and try to scare you concerning "soot buildup generated by the 3rd gen EGR process". Again, oil analysis has shown this not to be a problem in a normal running engine under normal conditions. Just use the best oil filter you can.

Don't fall victim to synthetic oil media advertising. If you need to change oil every 3K or 5K to make yourself feel right, then use conventional types.

well jay if you browse the cummins website they tell you using synthetic oil is a waste of money except in arctic weather conditions.oil never wears out, it only gets its additive package diminished or gets chemically contaminated with another chemical.
