Centlube® Long Life OAT Engine Coolant/Antifreeze — 50/50 Pre-Mix

Centlube® Long Life OAT Engine Coolant/Antifreeze is the latest advance in engine cooling technology — a ready-to-use 50/50 pre-mixed ethylene glycol-based coolant engineered for petrol and diesel engines in automotive, fleet, mining, agricultural and industrial applications. Based on patented silicate-free Organic Acid Technology (OAT), it provides virtually non-depleting corrosion protection for all engine metals — often lasting the entire operational life of the engine without replacement.

Available through Orbit Industrial in 20L, 210L drum, 1,000L IBC and bulk formats. Contact us for bulk pricing and delivery across the Western Cape, Northern Cape, Garden Route and Gauteng.

Ready to Use — Do Not Add Water

Centlube Long Life OAT is supplied as a 50/50 pre-mix — ready to pour directly into the cooling system. No mixing required. Provides frost protection to -36°C in the standard 50/50 formulation.

Why OAT Technology Outperforms Conventional Coolants

Traditional IAT (Inorganic Additive Technology) coolants rely on mineral-based inhibitors that deplete rapidly — requiring coolant changes every 2 years or 40,000km. OAT (Organic Acid Technology) coolants use virtually non-depleting organic acid inhibitors that form a thin, self-repairing protective layer on metal surfaces — providing extended, maintenance-free protection across the life of the engine. For mining fleets, agricultural equipment and commercial vehicles running continuous shift patterns, this translates directly into fewer coolant changes, lower maintenance costs and reduced unplanned downtime.

Features & Benefits

Feature Advantage & Operational Benefit
Patented silicate-free OAT technology Virtually non-depleting corrosion inhibitors — extended service life, often for the whole life of the engine, without the need for top-up inhibitor packages or premature coolant changes
Ready-to-use 50/50 pre-mix — no mixing required Eliminates the risk of incorrect dilution ratios in the field — critical for remote mining sites and fleet operations where incorrect coolant concentration causes cooling system failure
Protection for all engine metals — aluminium, cast iron, copper and brass alloys Compatible with all combustion engine cooling system materials — suitable for modern aluminium-heavy engines and older cast iron engine blocks without specification change
Frost protection to -36°C (50/50) — boil protection to +108°C Full temperature protection across the range of conditions encountered in South African mining, agricultural and fleet operations — from high-altitude cold starts to sustained heavy-load high-temperature operation
Meets or exceeds multiple OEM specifications Suitable for use in any combustion engine — petrol or diesel — across all major OEM brands including Cat, Komatsu, Bell, Volvo and most automotive manufacturers
Minimum 8-year shelf life in unopened containers Long storage life supports bulk stock purchasing for mining sites and fleet depots — no product wastage from premature coolant degradation during storage
Silicate-free — no silicate gel formation risk Eliminates the silicate gel formation that can block water pump seals and fine cooling passages in modern high-efficiency engines — a known failure mode of conventional silicate-based coolants
Borate, nitrite, amine and phosphate free (BNAP-free) Improved environmental and health profile — safer for workshop handling and reduces environmental impact of coolant disposal at end of service life
Store above -20°C — stable at ambient temperatures Simple storage requirements for bulk purchasing at fleet depots and remote mining sites — no temperature-controlled storage required under normal South African conditions

Frost & Boil Protection Reference

Concentration (vol%) Frost Protection Boil Protection (1 bar cap)
33% OAT / 67% water -20°C +106°C
50% OAT / 50% water — pre-mix as supplied -36°C +108°C
Note: Maximum recommended concentration Do not exceed 60% OAT Higher concentrations reduce protection

The only plush toys that last for my girl!
These are awesome! I have a 4 year old doberman and she destroys most plush toys in a matter of minutes. These are the only ones that last and are worth the money! Even once she does pull the stuffing out, the shell of the toy is still mostly intact and she'll play with that for a long time as well!

Our doggies favorite toy
Color: Yellow, Color: Yellow
This is our 3 dog’s favorite toy! We’ve had it for over a year, it’s lived outside for a while, was buried, found, taken all around the house. This toy shows up in the most random places and is still in tack (for the most part). They fight over this toy. They also have the pig from the same brand and it’s still alive! Other toys are usually shredded in a few days.

Not a strong toy for chewers.
Color: Yellow
Not quite as strong as its description. My dog chewed off its foot within the first 10 minutes . I expected it to be stronger because it’s made of Kevlar material but it’s not that durable. Save your money it is far from being durable / indestructible.

Soccer ball just for dogs
Size: 6 Inch Diameter, Color: Ocean Blue
I could say "soccer", and our shoodle would wag her tail ready to play soccer with a tennis ball so I tried out this real soccer ball with her. Mostly, she just wants to wait for me to kick it, playing defense, so she can chase it like the tennis ball. After that she wants to usually bite it or roll over on top of it as a way to secure the ball, but sometimes she will have fun pushing it around with her nose or paws. She still prefers the frisbee for play time outside since the frisbee is good for catching and for playing tug-o-war, but this is a good alternative that always gets her wagging with excitement. I wanted to get a regular 6" soccer ball for our shoodle, but this was a good choice for dogs for the durability and safety of the rubber material. The hexagons give the dog some grip to pick it up. The rubber is soft enough to grip and expel air when they do figure out how to grip it. The ball is designed to suck back in air when the dog releases the ball. - Durable rubber material ideal for dogs - Dog can squeeze out air to grip it - Ball fills back up with air after air is squeezed out - Can make more noise than a leather soccer ball - Noise is still tolerable when used indoors
