I hear different things. Like the oil changes, I’ll probably do my next oil change and do a sample to see what kind of condition the oils in and go from there. Because of the oil still good and clean at 25,000 miles then I’ll keep it at 30,000 mile intervals.

I run 10W-30 mainly because I run in Canada and it gets cold. I’ll definitely look into the gear oil, I normally run an oil additive as well. Not lucas but a moly style

When I started out as a company driver back in 2013 they had 2011 Daycab Freightliner Cascadias with 3.55 gearing Cummins ISX 450hp. The trucks were Ryder rental rent/lease or whatever and they did all the maintenance and so forth. The company (Menards) ran the holy hell out of the trucks between daytime drivers and nighttime drivers (1000 miles give or take in 24 hour period)


When it came to to do the already outrageous 30,000 mile service, Ryder just seemed to blatantly ignore it completely.... Basically telling the transportation office don't worry about it! So the oil changes on these trucks were never really done until they were into the 50,000 to 70,000. I am not kidding when it comes to the miles. They were even a few time s more than not that they were into the 80,000 to 90,000 mile range with one driver I remember saying that he was well over 100,000 miles on an oil change and was dumping a gallon of oil into it a day. Who fvcking needs an oil change right????

The company had nonstop problems with all the trucks by 400,000 500,000 miles give or take on them they had gotten rid of them and switched to CNG trucks. (which isn't any better LOL)

I remember when Ryder finally got around to doing the truck I was driving I would pull the dipstick when it got back from the shop and the oil was already blacker than sin in just short 5 mile drive. I only really remember it being done 2 or 3 times on the truck I drove.

I learned a lot about how the industry works when I was a company driver just based on half of the shi#t I said so when I became an owner operator I was gleaming with pride and knowledge! Then I came across this forum and was "woke!!!" My world became REAL small...


To the OP most of us on this forum change our oil at least 10,000 miles. I will post below again for you to hopefully see... again.

Quote: your average fuel mileage every 10,000 miles is ...

less than 5 MG -- Change your oil every 8,000 miles or so.

5 - 6 MPG -- Change your oil every 10,000 - 12,000 miles or so.

6 - 7 MPG -- Change your oil every 12,000 - 15,000 miles or so.

7 - 8 MPG -- Change your oil every 15,000 - 18,000 miles or so.

8 - 9 MPG -- Change your oil every 18,000 - 22,000 miles or so.

above 9 MPG -- Change your oil every 22,000 - 28,000 miles or so

I've seen these numbers so often on this site, what's a good rule of thumb for engine hours to miles conversion? Running PTO based operations (dumps) so we change our oil between 250 to 300 hours. The more I think about this, the more I think the intervals too long. We are under 5MPG consistently. Might hit 6 on a good day.

We have a lot of pto time as well and I change mine at 200 hours.

depends on how hard you work it.. but most of the time hours can be converted into rough-miles by multiplying them by 48 - 53.

EXAMPLE: (typical highway truck)...
8,000-hours * 48 = roughly 385,000 miles

EXAMPLE: (typical highway truck that is worked hard, low rpm's used, and has low fuel mileage)...
8,000-hours * 53 = roughly 424,000 miles
