If your shop goes through oil, we should probably be talking. 👀

We always keep 15W40 & 5W30 in stock and ready to go, with other oils available upon request.

Drums, totes, or regular deliveries — give us a call for pricing and see how we compare.

A lot has changed since Kleen Exhaust.

It started with Casey and his brother Jason cleaning DPFs, and over the years it’s turned into way more than that.

Now it’s Heather and Casey running Kleen Energy. We still clean DPFs, but now we’re delivering DEF, diesel, oil, antifreeze, shop supplies and whatever else we decide to get ourselves into next 😂

It’s pretty crazy to look back at where it started compared to where we are now.

We’ve come a long way, and we’ve got even bigger plans for what’s next.

New customers, new totes, same goal — keeping them stocked and moving. 💪

These are headed out for oil, DEF & antifreeze.

If your business goes through any of the above, give us a call. We’d love a chance to earn your business too.

Still buying DEF by the jug? 👀

If you’re going through DEF regularly, buying bulk can save you money and make things a whole lot easier.

• Better pricing per gallon
• Less time messing with jugs
• Less plastic waste
• DEF on hand when you need it

We offer DEF in 2.5-gallon jugs, 55-gallon drums, and 330-gallon totes, so whether you need a little or a lot, we’ve got you covered.

Going through a lot of jugs? It might be time to make the switch to bulk. Give Kleen Energy a call and we’ll get you set up!

🏆 Employee of the Year — Jerry Callaway

If you’ve ordered from us, chances are you already know Jerry.

He’s the one making the deliveries, taking care of our customers, and doing a whole lot more behind the scenes than most people ever see.

But to us, he’s more than an employee. He’s family. He’s been someone we can count on through the long days, busy weeks, last-minute deliveries and everything that comes with growing a business.

We don’t say it enough, but we appreciate the hell out of you and everything you do for us and for our customers.

Couldn’t think of anyone more deserving of Employee of the Year.
