Cat piston rings

Just went through SIS and dont see a listing for different rings other than what the C16 comes with, I even looked at the 15.8L industrial engines and they show no difference.

 

Is that to say that you feel my rings have not seated themselves in ? Cat put my truck on the dyno for the first hour or so. They wanted to have w.o.t. at varying RPM's.
In my application adding one gallon between oil changes is not much .
I also run 10w30 oil.
Just curious . I'm happy with my motor.

 

Yeah , 10w30 is what Cat recommends north of the border. It's all they stock now.
Good enough for me.

 

I'm paying $23.99 for a 5 L jug. I have a local shell dealer I need to talk to about getting drums to bring that price down.

 

It may very well be as good as they are going to get, but I have seen million mile cats that don't use that much oil. I would say that the rings are too hard to ever properly seat in, unless they didn't align the ring caps correctly.

If your happy with it that is all that matters.

 

Mileage isn't really the best yard stick. Fuel consumption is more relevant. If I were running around pulling a little tandem axle trailer with light loads or running thicker oil ( or an oil thickener ) saying that I add a gallon of oil between changes would be apples to apples perhaps. I can say, you will never see a million mile Cat or anything else do what I do without going through some oil. In fact, you won't see a million mile Cat (or anything else with a million on it) doing what I do. Unless of course the million was put on pulling flowers around first etc etc...

This being said, I can only compare myself against others I work around and I have no reason to suspect that I'm not doing well at all for oil consumption.

I'm due for my first overhead soon and I'll raise the question with Cat when I'm there.

 

Not to stray to far off topic I do agree completely that these rings shouldn't be used in a typical 5 axle operation. I'm still improving my situation at this point and I'm pretty hard on things.
