Frequently Asked Questions

Does Keller-Heartt charge for shipping on bulk oil orders?

Business addresses with a loading dock or bay ship free. Orders going to a location without a loading dock, or requiring a liftgate, carry an additional fee ranging from $50 to $100 depending on whether a liftgate, residential delivery, or both are needed, so it's worth confirming the delivery address type before checkout.

 

Can I use a Keller-Heartt coupon code on a bulk drum order?

Generally yes, since Keller-Heartt's discount codes are typically structured as a percentage off the full order rather than tied to a single product category. Because the company already prices close to wholesale on brands like Shell and Pennzoil, a percentage code applies on top of pricing that's already discounted from retail.

 

How fast does Keller-Heartt ship an order?

Most orders placed before 2pm Central time ship the next business day, and Chicago and Milwaukee area customers can request same-day emergency delivery if the order is placed before 5pm Central. Anyone who needs a specific product confirmed in stock before ordering can call ahead to check.

 

Can I return an opened drum of oil to Keller-Heartt?

No. Returns are only accepted on unopened, like-new product, and the customer must call the office to set up authorization before shipping anything back. This makes it worth double checking the viscosity grade and quantity needed before placing a bulk order, since an opened container isn't eligible once product has been used.

 

Does Keller-Heartt charge a restocking fee on returns?

Yes, a 50% restocking fee applies to all approved returns, and the shipping cost to send the item back is the customer's responsibility. Combined with the 10 day return window, this makes Keller-Heartt a better fit for buyers confident in the exact product and quantity they need rather than an over-order-and-return strategy.

Are all Keller-Heartt products eligible for return?

No. Houghton branded products are excluded from returns and refunds entirely, regardless of condition. Anyone ordering Houghton fluids should confirm the specification matches their equipment before completing the purchase.

 

Does Keller-Heartt offer rush delivery if I run out of oil unexpectedly?

Yes, through what the company calls its Emergency Delivery Service, which can dispatch bulk tankers with capacity up to 6,000 gallons for customers who need product immediately. This is generally reserved for larger volume needs rather than a single pail or drum order.

 

Can a small shop order from Keller-Heartt, or is it wholesale only?

Keller-Heartt states there's no application process required to order, unlike some industrial suppliers that require an account setup before purchasing. Orders can be placed directly online or by phone regardless of whether the buyer is a large fleet or a smaller independent shop.

Does Keller-Heartt sell to government agencies?

Yes. The company is an approved SAM supplier with an assigned CAGE code, which allows federal government customers to purchase through standard government contracting channels.

Saving Guide

Why bulk oil savings work differently here

Because Keller-Heartt already competes on wholesale pricing against brands most shops would otherwise buy at retail, the real savings opportunities are in avoiding unnecessary delivery fees and using a percentage code on top of pricing that's already below list.

Avoiding loading dock and liftgate fees

Free shipping applies automatically to business addresses with a loading dock or bay. Anything requiring a liftgate or residential delivery adds $50 to $100 to the order, so a shop confirming it has dock access before checkout, or consolidating an order to a commercial address rather than a home shop, can avoid that charge entirely.

Applying a sitewide percentage code to a full order

Keller-Heartt's coupon codes tend to run as a straight percentage off the entire order rather than being restricted to a single brand or product line, which means it's usually worth applying a code to a full drum or pail order rather than assuming it only covers a specific item.

Buying TRUEGARD instead of a name brand

Keller-Heartt's own TRUEGARD line is positioned as one of the more affordable options in its lineup and is formulated to compete with major brand lubricants at a lower price point. For shops that don't need a specific named brand for warranty or equipment manufacturer reasons, TRUEGARD is often the lower cost choice before any coupon is even applied.

Ordering the right amount the first time

Because returns carry a 50% restocking fee and only unopened product qualifies within a strict 10 day window, the more reliable saving is getting the right grade and volume on the first order, calling ahead to confirm exact specifications rather than over-ordering with plans to return the excess.

What to check before checkout

  • Confirm the delivery address has loading dock access to avoid liftgate or residential fees

  • Apply a sitewide percentage code before assuming it's restricted to one product category

  • Consider TRUEGARD branded product if a specific name brand isn't required

  • Order before 2pm Central for next-day shipping, or call ahead for same-day emergency delivery in Chicago and Milwaukee
