THE SECRET WEAPON IS IN THE FORMULA.
MOLYBDENUM DOESN’T BABYSIT METAL. IT PROTECTS IT.

Here’s why CONVOY® 15W-40 CK-4 is more than just another diesel oil.

It contains molybdenum, a friction modifier designed to help improve performance and efficiency. In plain English: when metal is under pressure, heat, and constant movement, friction is the enemy — and molybdenum helps fight that battle inside the engine.

Pair that with Convoy’s parasynthetic formula, enhanced shear stability, thermal and oxidation stability, soot control, and protection against wear and corrosion, and you’ve got a diesel oil built for engines that don’t get pampered.

Because your truck doesn’t need motivational quotes.
It needs oil that can take a beating.

Run CONVOY® 15W-40 CK-4 and put serious friction protection to work. Contact your Conklin Distributor today.

DON’T FEED YOUR DIESEL CHEAP OIL.
HEAT. LOAD. GRIT. CONVOY DOESN’T FLINCH.

Your diesel doesn’t live an easy life.

Heavy loads. Hot runs. Long hours. Dust. Stop-and-go punishment. Cold starts. Hard pulls.

That’s exactly why CONVOY® 15W-40 CK-4 exists.

Built for diesel engines with or without exhaust aftertreatment systems, Convoy delivers serious protection against wear, corrosion, sludge, varnish, soot, oxidation, and heat stress — while helping reduce friction for improved efficiency.

This is not “whatever’s on sale” oil.
This is protection with backbone.

Ask your Conklin Distributor for CONVOY® 15W-40 CK-4 before your next oil change. Your engine will know the difference.

RHINO® DOESN’T TAP OUT.
When the load gets heavy, the heat climbs, and the equipment starts taking a beating — weak grease gets exposed fast.

Rhino® #2 Parasynthetic Lithium Complex Grease with Moly is made for the brutal stuff: high temperatures, heavy loads, shock loading, moisture, and hard-working equipment that doesn’t get the luxury of an easy day.

Use it where failure is not cute:
farm equipment, trucks, trailers, construction equipment, industrial machinery, bearings, bushings, pins, pivots, and high-pressure grease points.

It clings.
It protects.
It takes the hit.
And it keeps working.

Don’t baby your equipment. Armor it.

STOP LETTING GUNK CHOKE YOUR ENGINE.

Rough idle? Hard starts? Stalling? Sluggish throttle?

That’s not “just how it runs.” That’s dirt, gum, and varnish robbing performance like a thief with a socket wrench.

Conklin Carb N’ Choke Cleaner quickly cuts through stubborn deposits on carburetors, throttle bodies, PCV hoses and valves, choke parts, and linkages — helping restore cleaner operation, better drivability, and sharper response.

It penetrates fast.
It dissolves the crud.
It leaves no residue.
And it’s safe for oxygen sensors and catalytic converters.

Get the gunk out. Get the performance back.

Spring Starts Cold. Your Engine Doesn’t Have To.

Winter’s over—but your engine is still paying for it.
Cold mornings, temperature swings, and months of brutal starts leave your engine worn down and exposed. And just because it’s spring doesn’t mean the damage stops. Every startup is still a fight—unless you take control.

Head Start™ hits before your engine takes the hit.
This high-performance formula coats critical components instantly, cutting friction when your oil hasn’t built pressure yet. That means harder starts, smoother response, and protection that doesn’t wait for ideal conditions.

You didn’t baby your engine all winter just to let spring finish it off.
Step into the new season with power, not problems.

Run Head Start™—and make every start count.

Summer isn't that far off.
