Mechanic won’t use oil I’ve chosen

This does not sound like a guy who will fall in line. If you are okay with this then keep him on.

But either you are making the decisions or he is. Who is the manager here?
If you are going to be the manager, end this.
If you are going to let him tell you how to do things ( which is what he is doing passively), then continue on.
I manage people, and I would not put up with this.

Now the question, are you up to the task of managing this/him?
Not everyone is.
You need the ability to listen then give firm concise instructions, and hold him fully accountable, no wiggle room, no chickening out, and not dealing with him as a manager.

I have the ability to give him the firm instructions on what I expect.
Problem is we need him right now. So I am meeting him in the middle, takeing away his excuses and he has no choice but to fall in line until we find a suitable replacement.
 
I think persuading him on how 6$ a QUART of 15w40 is TOO MUCH! Especially some warren oil.

You could just say that money is tight and that there is a need to use cheaper oil and only one type of oil, and that you are not responsible for any damage caused by using one viscosity versus different ones for each vehicle.

Yes and that's why you should be looking for that replacement right now. By the way what date is his contract up month, day, year?
 
No micro managing. Trying to get things under control.
$60 for a oil change is twice as much as it should be.
There are ZERO service records for any of the fleet in IN. I have no idea when they were last serviced. I know he’s not checking fluids once a week. All of the air filters are clogged.
Transmission fluid is black. Hubs low on oil. Wheels are black instead of white because they are covered in hub oil and road grim.
What does this guy actually do to earn his salary? Sounds like hes over paid or lapping up gravy to me.
 
It is HIS shop, WE pay for the lease on the building. If we let the lease run out, he has to move on or take it over himself.
We pay him to prioritize our equipment In all manners, maintence and repairs.
Tell him to fall in line or you're pulling out and he'll have to pay for the building lease. He would be an idiot to not work in a free building, especially if he's doing other work besides your fleet. Sounds to me like your fleet is being put on the back burner while he uses the free building to make other money while his gaurenteed gravy salary keeps coming through.
 
This situation is akin to hiring a contractor to redo your master bath, and then complaining about which thinset, silicone, and grout brands he's using. Who cares. What really matters is the finish materials (the vehicles) and fit and finish (how well they're maintained).
There are hardly being maintained. He's putting the fleet on the back burner while he uses the free shop for other business, and still getting paid a gaurenteed salary to barely maintain the fleet. Sounds like quite a scheme this guy has going.
 
Either you have the option to can him and get someone else in there that will follow your directives, or you have to live with what he does.
Let him do his job without big brother watching over him. Main thing is the oil gets changed regularly.
 
Not even close to the same thing.

One unit is $70k new. I need it to last 20 yrs. That is the expected service life. You re-grout your bathroom every couple of years, it’s not expensive to do and the grout brands are all pretty close in quality.

Motor oil‘s vary in quality by large margins. The minimum quality required will not provide the long term protection needed to maximize service life of the units.
If the oil meets the requirements the vehicle mfg. calls for it should be good to go. There might be slight quality differences between brands but not enough to be worried about assuming the oil meets the vehicle mfgs. requirements. I'd be more concerned running 15W40 year round in a cold climate to be honest. Regarding the tech, I'd be using someone else by now.
 
An issue that I havent seen discussed is his lack of record keeping. If any of the trucks are involved in a serious accident an astute lawyer could/will ask for a copy of the service records including a record of the weekly check sheets (which likely dont exist) If you cant prove they were properly cared for then they will assume they werent. A big liability in such a litigious society.

He’s paying $6/qt for 5w-30, for the diesels he is paying almost $30/gal.

Looked over the contract again, it is open ended. Meaning either of us can end it at anytime.

Early next year we will be ending it unless things turn around.
Until we find a replacement we need him.

Exactly. I asked him to replace the batteries on one of the trucks two weeks ago because it has either been slow to turn over or needing a jump everyday.
He has yet to do it. So when I go back down there next week I will replace them.

The trucks are parked inside a heated building when not on the road. Cold starts are not a concern. Once on the road they run all day and are driven hard. Like race track hard. Full throttle acceleration hundreds of times a day for 10 hours 7 days a week.
The diesels are driven the same way, and when on the expressway they are foot to the floor take it to the governor and hold it there for an hour, take the exit and a half mile later park it and shut it off until tomorrow.

Yes. Exactly. Maintence and repair records need to be kept for proof of what has been done and when. Not only for possible litigation and resale purposes but also for the over health of the fleet.

You expect fleet vehicles to last 20 years? Are they not being driven much?

A fleet vehicle can last as long as you want it to. I’ve worked on coaches over 30 years old still in daily use. They made more money that the newer part of the fleet as paid off some 29 years ago and repairs were lower cost due to older tech
