Oil change interval for heavy use Predator 5000 inverter generator

[Cmobile]

My son works out of his truck/cargo trailer. He works at a site for a few hours, then on to the next.

He powers is trailer AC, tools and lights with a Predator 5000 inverter generator (just upgraded from the 3500 after starter failed and pull start string broke, he went to HB and bought the 5000)
Generator runs, on average, 8 or so hours a day, M-F.
I think the manual has 1st oil change at 20 hours then every 100 thereafter. So oil changes every 2.5 weeks or so.

After break in, with 5w-30 (STP from HF) I wonder if we could safely extend oil change intervals by 60 hours if we went with an oil like Mobil 1 Extended Performance in a 10w-30, Mobil 1 High Mileage 10w40, or Euro Spec 0w40 or 5w40.

What kind of ambient temps does this generator typically run in?

Sounds like a perfect candidate for Amsoil Small Engine oil - put it in and run it 200 hours per OCI. I use the 10W-30 in my generators.

The Manual for the Predator 5000 does say every 100 hours.


My Predator 4375 says every 20hrs. I have High Performance Lubricants Premium Plus 0w40 in it. I'm going to go 50 hrs.

Ran it earlier this week, some car accident took down a pole and transformer. Ran it 8 hours.

For longevity, I'd never go past a 100 hours interval on anything air cooled, regardless of the oil. That's just me.

The taco girls at the corner near my house run theirs 8 hrs a day in 100+ heat. They change the oil every week.

I go 100hrs in my Wen inverter generator using HDEO 10w30 or 15w40. I would do the same with his. Buy some store brand HDEO and roll on. If you want to go longer I'd run a 5w40 HDEO.
