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

An excellent introduction to plate tectonics
Format: Kindle
My rating is 4.5 stars. I dinged the book because I wanted more about geobiological evidence for and against plate tectonics, and because it didn't mention other global tectonics, such as single-lid tectonics. Read Robert Stern's article in the May 2025 issue of the GSA bulletin.

Soft, Good Smelling, Cleans Great!
Size: 6 Fl Oz (Pack of 1), Style: Facial Cleanser
This is easily my favorite facial cleanser I have used TO DATE. The first thing I always notice with hygiene products is the scent, and you can trust me when I say it's the best smelling scent you'll recieve on any Male product. Scent - The best way to describe it would be Pine, vanilla, with a refreshing kick. It is SO nice! Cleansing - This is, surprisingly, one of the best facial cleansing products I've ever used. It goes on gently, and does not have that "burning" sensation that some products leave on your face. It washes off softly and leaves my face feeling VERY smooth. The only small problem I've run into is a little bit of dryness left on my cheeks, but my skin is VERY sensitive so it's understandable. A very small amount of moisturizer fixes that easily! Conclusion - It cleans my face very gently, and leaves it feeling clean, smooth, and hydrated! The scent is fantastic, unique, but not too strong. I recommend this to ANYONE! And would be an amazing gift!!!
