You bet. Changing every 3-5 the oil will be in fine shape. It's just a matter of how much fuel dilution you're getting. You might just test it once and see what it reads. Then you'll know that running 3-5k will never be a problem.

 

i use the rotella diesel oil change every 5000 miles also

Waren Gibson transport use that oil in there fleets also
they go alot further on oil changes


i can not figure out ......a big diesel rig ...how far do they go before changes

 

What do you think the Amsoil is good to for mileage? I've talked to a different Amsoil rep on another forum and even he didn't recommend going past 10k on the Amsoil, and I believe he personally changed it at 7500 miles, just because of how high shearing the 6.0 motor is. Your thoughts?

 

The 6.0 doesn't shear down past a 30w So get 10w30 and shearing isn't a problem.

 

I have been running Shell Rotella Synthetic since 12,000 miles, and now have 49,000 miles. It is really great oil. Truck is quieter too. In fact I run it in everything I own except the lawnmower and log splitter. I even put it in the old 1987 6.9. It leaks a little, but it is 23 years old.



Cheers

 

I'm new to diesels, this thread really hasn't helped much. How often do you change the oil? Every 3k? Or longer? Is rotella any good? What is the difference in running synthetic to conventional? What's the price?

 

5k mile oil changes for most of us. Some are going 7500-10k, but they're doing oil analysis to verify it.

Figure to do an oil change with a motorcraft oil filter and conventional 15w-40 Rotella, you're looking at probably $80 or so. To do it with Rotella synthetic 5w-40, figure more like $150.

I've used both the non synthetic and the synthetic and like both of them. I use the T6 synthetic currently in both my 6.0 and my TDI.

 

Thanks that cleared it up

 

I have been doing 5,000 mile changes because I felt I fell into the "extreme use" category. Now that I am not doing any heavy towing I am going to push to 7,500. I am running Rotella T-6 and will have the oil analyzed.

 

I ran Valvoline Blue Extreme 5W-40 in my 06 from 500 miles (new), changing it every 7500 miles, until I started experiencing what I concluded was injector stiction issues at roughly 55,000 miles. I changed to a 5,000 mile interval and the stiction issues went away.
I only drive my vehicle 22 miles to and from work each day. I thought this was not extreme, however, evidently it must be, since a 5,000 mile change interval is required to keep the stiction issue away.
