Hello, everyone.

This is Enta.

I have a job coming up involving a 40-meter-class dewatering borehole.

To that end, we were conducting casing inspections and checking the number of units.

We also inspected the machinery.

For an engine-type hydraulic unit, you'd probably use engine oil, right?

So, I checked the oil level with the dipstick, and—what?!

The oil isn't reaching the dipstick...

Since I’d been out for about three months last year and hadn’t had it inspected, I’m glad I did it now.

However, with an older engine, engine oil can be burned along with the fuel or leak out, causing wear and tear in ways you might not even notice.

Before you know it, you’re like, “Wait, it’s already gone!?” Haha.

It seems like it would be better to inspect things on-site about once a week rather than waiting until I get back from the site to do it...

Engine oil is a key part of any vehicle inspection, so if it runs out, the engine could seize up—that’s why it’s important to keep a close eye on it.

I worked while teaching a young employee how to change the oil.

Drain the old oil, then add the new oil. (Drain from the top first, then from the bottom the second time.)

No element replacement this time.

Start the engine and let it run for about 30 minutes. (Flushing)

After that, drain the oil, refill with fresh oil, and you're done.

We added additives specifically designed for industrial use—to prevent seizure at high RPMs and improve efficiency—to the latest oil.

It's super expensive, but it'll make your engine the best!
(By the way, we're an agency. That's because we want to use as much of it as possible! We do share some with companies we know, though.)

So, I forgot how many casings I checked during the casing check, so it'll have to wait until next week, lol.

But with a 40-meter-class boat, I guess I'll have to buy a whole new set of casings...

See you later.
