But here is the thing, you can prevent downtime by using the motor oil for YOUR application.
I'm in charge of $3.5 million worth of equipment, one of my jobs is to maximize profit while keeping costs down. If those wheels aren't turning we're losing money.
If I blow up a $20,000 diesel engine there's going to be hell to pay.
One Godzilla is $10k new your cost, mine is $7k-ish depending on current demand.
The 6R140 has valve body issues, most replace the whole transmission, $6500 just for the trans, I went a different route and replaced the valve body. Everyone said I was nuts and wasting money, guess what. For $700 out the door, parts, labor and programming, I have saved the company over $17k.
Now others in my field are doing it too and saving money.
Unlike government where you're not worried about profit margins, in transportation profit's are small. What we don't make in profit we make in saving on repairs and breakdowns.
You can be a lemming and follow the heard off the cliff, or you can experiment and see if something works better for you.
Remember that cars are made for the masses, and the masses are asses that know nothing about cars.
