B61 END-673 Engine oil change

[Frank Y]

I'm changing the oil in the truck now that I have filters, and need to know a good brand of oil to use. My Case skidloader gets Case diesel oil and my gas trucks, and antique Chevy get Castrol. Anybody use Castrol Diesel 15-40? I think I'll need about 25-26 quarts, sound right?

Thanks in advance.

Bout any 15W40. I like the Pennzoil products but each his own. My 673 gets 30W because that is what it came with back in the day.

Read a good article once comparing straight 30 to 15W40.  For heavy pulling, they still recommended the straight 30.  I would go into the details, but it would start an argument.

My teacher at caterpillar engine school had a conniption if you spoke of any oils other than 30 weight in the summer and 10 weight in the winter but that was 40 some years ago.

Oil blends and technology has come a long way in 40 years. My last oil change was with Rotella but I think I'm going to give Mobil Delvac a try next time in my ENDT-675.

A friend stopped in today and dropped this new bucket of oil off that he's had since he sold his R600. He doesn't remember why he didnt use it. I'm going to do some research on it and see the specs compared to pennzoil. Any problems with using it that anyone is aware of?

In the last two fleets I was in charge of I used union 76 15-40 I had real good results.

Don't think any of the oils will hurt. It is pretty much a personal choice. My END 673 P engine used the Delvac 15W40 before the rebuild. Most of us don't pull heavy trailers or other items today, like our trucks once did, new. Just my observance through the years. As I recall, Freight train aka Larry uses Rotella and has had very good results and he uses his Mack, cross country pulling a trailer. 

Ok Larry it is your turn to chime in.

+1 on Rotella.

Thanks for the opinions guys. Im still waiting on the filters. Apparently they got lost in the mail. I guess ill just drop the oil and pull that inspection/sediment pan in the meantime. Can that be put on with gasket maker or is there a gasket that should be purchased?

I worked on Cat and Cummins for 18 years, most of the trucks I worked on used Rotella 15W-40 and the owners were very happy with it.

Here is the absolute best advice I ever heard regarding oil:

 

1. some is better than none. And,

 

2. clean is better than dirty.

Rotella for me too.

Thanks for the help everyone! I Appreciate it! Pics coming when it comes out for a washdown.

Old traditions (habits) die young. I'm a retired Firefighter and traditions are very hard to break in the fire service. Still to this day I cannot wear brown work shoes. Black shoes and white shocks are part of the uniform. One tradition I found when I first became a Firefighter was every time we returned from a run we'd wash the wheels of our equipment. If we left the firehouse and got recalled a block away before we backed the trucks in station we'd wash the wheels. Clean or dirty the wheels always got washed. The rest of the truck could be filthy and put away but the wheels had to be washed. WHY? It's a tradition from back in the days with horse drawn equipment. You ALWAYS have to clean the shi_ off the wheels.

I've always used Rotella but I'm willing to change it up and try something different. A friend is a synthetic oil dealer. I tried synthetic oil in the Wife's Jeep 30,000 miles ago and kept checking it along the way and it always came back clean and I didn't need add a quart along the way. I figure that is proof enough for me to try something different. But I still am not wearing brown shoes. 

Side note - I tried synthetic gear lube in the transmission of my 1969 FLH and the bike hated it. Ground gears with every shift.

Clean rims/tires always makes a vehicle look clean.  Nothing worse then brown ugly tires on a clean vehicle.  I do get the horse and buggy deal!

The thinner oil makes the shafts spin easier, thus shift timing gets screwed up.  I started running synth in my race car and it takes much longer for the shafts to stop when trying to put it in gear after starting the engine with the clutch out..  The old 90w gear was much thicker!
