The use you described, "Fully loaded...Dirt roads. Tons of idle time, lots of foot to the floor wide open throttle," is pretty much the definition of severe service. I'm pretty sure you'll find Ford will recommend 5K oil changes.
Yes. Please use an oil analyzing company when accomplishing extended drains. You might be disappointed,.. or not. And yes, please try Kirkland's oils, and try their SN-rated, HD 15W-40.If your trying to save money, i think kirkland or super tech full syn is well suited for your applications, since your vans will see no cold starts go 5 or 10w30 and experiment with one van on 15w40 ?? As you state fuel mileage is not much of a concern !

Make sure you have a top-notch battery in the truck with the 15W-40 oil, especially if the trucks are cold-soaked during a bitter day in the field.![]()
I plan on doing SOS on the V10’s and V8’s to see how demanding each is on the oil.
I don’t know when you started reading on the thread, but these are parked inside a heated building when not in use and run all day long. They are never shut off during the day, except maybe for the rare occasion.
I think you are maybe treating these like you would a personal vehicle. Fleet maintenance is triage. You don’t have enough money or time to keep them all perfect. Your goal is to get the vehicles across the finish line with as little effort and money as possible. You are going to lose some - no matter what oil you use - and it’s ok.
Those Ford v8’s will go hard for a long time on just filters and oil (and tires - lots of flat tires). See if you can’t find a deal on a drum of something that meets the -A1 Spec and call it good. A supply of jobber oil and air filters will work just fine as well.
The one thing I learned was that tires and air filters needed the most attention. Oil/filter was an afterthought.
Those Vegas taxi fleets aren’t getting synthetic - and those 600k mile motors do ok, no?
Shouldn't you go by the engine hours instead of mileage? Ford-approved 5w-20 every 200 hours. And that's it
I didn't remember the "not being shut off" or "shut off for long" part. That's good. Give that SN-rated Kirkland 15W-40 a try then! I'm thinking it's likely your best bet.I plan on doing SOS on the V10’s and V8’s to see how demanding each is on the oil.

That’s why I was thinking about the Rotella T6 5w-40, .....I’m just not sure about using it in a brand new engine designed for 5w-20.
I can service those engines in my fleet for $18.93. A 55 gallon drum of motorcraft synthetic blend for $530.25 works out to $2.41 a quart. A case of champ ecore filters is $24. 7 quarts and a filter is all you need. That’s not even the cheapest option. If I buy Chevron Supreme it goes down to $15.69. I switch around based on sales and what my mood is that day. I have lots of favorites. We do sample too and none have given bad results that were the oils fault.I want “one and done”.
I know that Dexos is only a rating and not brand specific.
If I can do a PM for under $50 that would be great.
Lots of experience with Chevron Supreme as well. It's an excellent, value-priced oil with a strong add pack.I can service those engines in my fleet for $18.93.

It took me a long time to figure out your first point when I took over maintenance and repair of a fleet of forklifts. The old way was every filter at every pm. They were changing hydraulic filters with only 300 hours on them. I made up a basic spreadsheet and combined with dating everything with a marker or paint pen the maintenance cost is a fraction of what it was. We now loosely follow the manuals and only touch it when it’s required. I can see a new lift through 10,000 hours with around $5k of maintenance and repair on average where they had been approaching $15-20k. Takes a serious amount of labor to do basically a 4,000 hour service every 300 hours.I think you are maybe treating these like you would a personal vehicle. Fleet maintenance is triage.

You'll be scorned on BITOG for mentioning this, LOLThose Vegas taxi fleets aren’t getting synthetic - and those 600k mile motors do ok, no?
Here is a link to the 2018 Camry Hybrid VVTI owners manual printed for Australia where we have no requirements to use the same oil that was in the car when the factory put it in for the standard fuel economy test.
Toyota say you can use 0W16, 0W20, 5W20, 5W30, 10W30 and 15W40 to keep your factory warranty. All in the same engine. As long as it meets your cold weather starting requirements.

I don’t believe this one oil weight only stuff, it certainly doesn’t exist in other parts of the world.
