oil question, NOT race related but Racers would know

Good question. I've been doing it for years.

Some of those Cummins diesels hold 20 to 30 quarts.

If your fire chief is that foolish, tell him he needs Rotella T6 and then if he'll let you have it use it for anything.

Changing oil at 200 miles is probably doing more harm than good. Make sure you pre-fill the diesel oil filters especially the big ones.

Freightliner told me to use synthetic and change the filter at 10,000 miles and then change oil at 20,000. Some truckers go nearly a 100,000 miles just using a regular analysis and filter change.

Oil is way to expensive to change more often than necessary. Same for diesel air and fuel filters. Diesel fuel is much cleaner than it used to be.

For years a normal oil change in my race car also meant the same oil went into the tow vehicle.We only used regular oil but changed it maybe 50 passes in a 12 second stocker.

You use 200 miles as the factor in determining the overall amount it was used. In something like a fire engine how many HOURS was it been used would be more relative to it's condition.

I can check the HR meter on the next Diesel we change. I do jot them down for a referance. And seeing how this stuff is cleaner coming out, than some bulk oil we use on the farm that goes into the farm tractors, I know its not a lot of hrs.

Good point though.

My heart goes out to you. One of the reasons I retired after 31+ years in the government fleet business ( including going through 4 fire chiefs ). I'm sure you are not running recaps on any of your fire trucks ether. Hard to deal with someone with the title of "CHIEF". Before I retired, my shop was using rerefined oil ( yes, used oil ) and had recaped tires on everything. Tip - it aint worth the fight. If you are a conscientious employee, you need to look for work outside of government.

Hours on all heavy equipment. We used 100 hours = 3000 miles as a general conversion rule. All heavy equipment will come with an hour meter, and their ( diesel Mfg )suggested change interval will be in hours. I have never seen an oil change interval less than 200 hours except on street sweepers. Maybe the chief ment hours? 200 miles = 15 hours. Ridiculous.

Absolutely correct. It's hours not miles on these kinds of vehicles. Idling can be worse than hard use.
