I tow a 5,600 lb (loaded wt) TT with my Ram 1500 5.6L gasoline truck. I also have a few hundred lbs in the truck, but all in all I'm well within the towing capacity of the truck.

I had to put a new (rebuilt) engine in it last year. That engine has 11,000 miles on it.

I changed the oil to synthetic right before we left on a 10,000 mile trip. We've driven 6,000 miles so far, of which probably 4,000 have been pulling the TT. I travel about 60MPH, which results in RPMs of 1,500 to about 2,200 most of the time, with the higher number being pretty common. Obviously, higher RPMs happen in the mountains. We are in the West, BTW.

Recommendation for synthetic oil is to change it after 10-15,000 miles, but I'm sure that supposes unloaded passenger car use.

My question: given that I've pulled the load 4K miles, plus 2K unloaded, when should I change this oil?

Thanks!

Oil change cheap. Motors expensive.

Mobil 1 EP synthetic claims 15K miles of protection. I usually change at around 8k if towing a lot and 10-12 K when not towing too much. I agree with checking the manual though

Highway miles are easy on the oil. I would go another 4,000 without worry. Change it when you get home. Do check the oil level.

What is the oil capacity? That is also a factor in how long the oil will last. My E450 has just a 6 quart oil capacity but a large oil cooler. I run Mobil 1 5W-20 EP. Changes every 4000 - 4400 miles and have done Blackstone oil analysis and get similar numbers to their average change interval of 4400 miles for that V10.

At 4000 miles it had a TBN of 4.0 (total base number, measure of remaining additive package) which is well above the minimum that Blackstone recommends of 1.0.

Presumably most of those V10s are trucks that are not always carrying loads. I run the EP since it might take up to 1.5 years for it to reach 4000+ miles.

OP, don't listen to this guy....haven't seen a gas motor pickup yet, and I've had most of them, that has a 10k OCI recommendation.
Find out what the recommended OCI is for your vehicle as we have no idea what it is.
No such thing as a 5.6L Dodge.


What have you done the rest of your life preceding this oil change for that vehicle or others?
Or is this your first vehicle? If so I apologize.

And you changed it at 5k miles the last time. Why?
Just a hunch?

Oboy, well I use nothing but synthetic oil in everything from lawn mowers to tow vehicles.

Tow with a Ram 2500 with 5.7 and never exceed 5000 miles between oil changes.....my dipstick is begging for an oil change, dirty oil.
