You can read about oil and OCIs until your eyeballs hurt over at this site. To me it's just oil and I change it every 5k. I think these people worship oil twice a week.[emoticon]

It's funny you should say "change oil every 5K" I come from the UK and the 'standard' oil change number used in the UK is change every 5K.

Only when I came to teh US did I ever see change oil every 3K

Is this something that was made up by the oil and filter manufactures or is genuine?

5K seems reasonable to me!.. How about everyone else?


Back in 98 at a Cummins dealer I saw that the reccomended oil change on the 275HP ISB pushin a motorhome was 15K miles. Ever since then 8-12K for me.

The three thousand mile oil change was thought up by the quick lube oil change places looking to drum up more business....

You can stop all the guessing by having an oil analysis done the next time you change the oil(I use Blackstone Labs), they will give a mileage figure based on science.

I've always been one for keeping my vehicle as "Bone Stock" [emoticon]I'm learning the jargon :-)

I 100% agree.

BTW When towing I use synthetic oils with no additives.

So are we saying that we should only use Manufacturer Oil filters? Is this really practical?

How do I know a good oil filter from a bad one? same deal with air filter and other consumables. It's not always practical or economic to use GM, Ford, Dodge whatever parts?

One other related question? How good and trustworthy is the "Oil Life Indicator".

On my current GM Yukon, when I reach 3K miles I change the oil using synthetic but the change oil indicator maybe only indicating 50%. Am I being over careful and wasting my precious money, or should I just trust the oil life indicator more?


Use Napa Gold (Wix) filters or AC Delco and you'll be just fine.

I use the oil life indicator is been designed to accurately determine when a change is needed. But the important thing is many of our tow rigs may not even see 3-5k per year. It's important to change it once a year even if the mileage doesn't indicate it. YMMV

I recall the commercial and motorhome ISB's hold MUCH more oil than the ones in the Rams! (Offhand, my friend's Blue Bird holds 16 quarts.)

What's the OCI with the Blue Bird John? I'm surprised the bus and MH doesn't have a C series in it. The B is more suitable for a car.

In daily service, I recall 250 hours. Now, in limited use, annually.

Thanks for the input on oil changes!

It seems that the oil monitor and 80% or 5K whichever comes first maybe a good rule of thumb!

To be honest, my current TV is a 1/2 Suburban 4WD and when towing and get an oil change I always get the rear transfer case checked at oil change. Several times it's been observed that the oil in the transfer case is either slightly low or a little dark. So this seems to be a good reason to go for the 5K

I'm hoping on the new TV a 1 ton 3500 4WD that I wont experience this heavy wear on the rear transfer case lubricant!.. any feedback?

The Cummins ISB is common in school buses and medium trucks (most big Ryder trucks 2008 & newer have the new 6.7 ISB)...the big 8.3 ISC is drastic overkill.
