The choice of lubricant for any equipment system is guided mainly by the OEM recommendation.

The heritage of a brand is very key in deciding on a good lubricant. Most major brands invest significantly in research and development to ensure a brand is superior. In addition, there are international standards that guide on determining the quality of a lubricant. The SAE (Society of Automotive Engineers) & API (American Petroleum Institute) classify lubricants on the basis of viscosity and quality / performance respectively. These classifications would offer a good guide.

The recommendation for what oil to use for your machine / engine is based on what the manufacturer indicates on the user manual. From a technical position, the thickness of a lubricant varies with its temperature. While a lubricant may look thick at ambient temperature and therefore indicating a strong lubricating film, when a machine reaches its operating temperature, the viscosity may break significantly to being too thin and therefore offering poor lubricating film. So a thicker oil is not necessarily a better oil than a thinner oil.

Based on the formulation of your engine oil, the key raw materials get depleted over time and therefore need to be replenished to keep performing their functions optimally. If you don’t change, the engine parts will be exposed to damage as a result of depressed functioning of the depleted additives.

K-Lube has been tried, tested and proven over time. The brand is manufactured from highly refined base stocks and advanced additive technology to deliver a premium product that meets the diverse tough operating environments. In addition, wide K-Lube product portfolio ensures all your lubricant requirements are met under one roof.

When formulating oils and in particular engine oils, there is a careful balance between the various additives and base oils to achieve the intended performance characteristics of the lubricant. Most of the off-shelf additives are intended to achieve a specific function. While performing that function, they could alter the raw material balance and end up negatively impacting the performance of the lubricant. So it is advised to avoid them.

As a responsible citizen, we strongly advice for safe disposal of used oil to protect our very fragile environment. We have arrangement across all our retail network to collect used oil from our customers. We have NEMA approved agents who collect the used oil for safe disposal.

No. There are different categories of oil with different applications. Common categorization can be automotive oils, specialty oils, industrial oils, marine oils and aviation oils. Oils can also be categorized based on the base oils used, e.g. mineral oils, synthetic oils and semi-synthetic oils. Each of these categories can be broken further. Thus it is good to know which oil you require based on application and specification and seek to get the suitable oil for your application.

DOT 3 specification of Brake fluid is no longer allowed for sale in Kenya. DOT 4 specification is the current minimum specification allowed in the country and is fully compatible with systems that require DOT 3 specification of brake fluid. DOT 4 specification is better than DOT 3 specification as it has higher wet boiling point and has better hygroscopic tendency (affinity to attract moisture from the atmosphere, which affects quality of brake fluid).

At the end user point, good quality coolant coloured pink coolant is based on Glysentin G40 specification while the blue-green coolant is based on Glysentin G48 specification. These can be mixed at end user point, though the blue-green fluid has more OEM approvals than the pink fluid. However, it is good to watch out for counterfeit products, which are basically dyed water.

A call or a visit to the lubricants department at Rubis Energy Kenya will help you get very precise information on lubricants without relying on unverified sources that can at times be very misleading.

All K-Lube products have a security seal that you should always ascertain that it is intact during purchase. This can be a branded induction seal for the small packs or a branded metal seal for the 20lt and drummed products. As a double check, buy your K-lube product only from authorized distributors (and their nominated agents) or from service stations.

Lubricants have expiry date indicated on the package containers. This is for safe use period. It is worthy to note that the Chemistry of most lubricants does not change if they are stored in good storage practices and will not just go bad or stale after the expiry period. Lubricants can however deteriorate in quality in storage if not stored in a proper way. It is advisable to use only lubricants that are within the safe use period and have any expired lubricants tested in a laboratory to guide on safe handling and disposal.

There is a common misconception that brake fluids and transformer oils can be used to treat cuts and wounds. These products are not medicinal in nature; neither are they prepared with ingredients that have been passed as medicinal by the pharmacies and poisons boards. They may have other undetermined effects on human body and thus we discourage any such applications.

Due to the thermal stability of transformer oil, some unscrupulous people use it to deep fry food. However, transformer oil is carcinogenic (can cause cancer) and should thus never be used for cooking food.

Liquefied Petroleum Gas (LPG) is a mixture of propane and butane either produced from refining or extracting from gas field.

Safety: LPG is a clean burning fuel that is low carbon, emits virtually no black carbon and does not spills. LPG prevents asphyxia accidents. Cooking autonomy: because a 6 kg cylinder will give you 1 month of cooking autonomy.
It has a higher heating value thus more efficient than other cooking fuels. LPG doesn’t contain sulphur, so it burns a lot cleaner

Always purchase your cooking gas from a branded RUBiS, Kenol, Kobil and Gulf Energy Service station or an authorised K-Gas dealer.

For the 13kg, you will need a regulator and a hose pipe.
For the 6 kg cylinder, you will need a burner and grill.

Ensure cylinders are in an upright position on the vehicle floor and secured so they cannot move.

Store cylinders in a well-ventilated area, away from open fires, electrical appliances and power points.
Do not store in a closed area. The gas is heavier than air and will “flow” into low points and collect, causing a flammable mixture.
Never store the cylinders close to a heat source or in direct sunlight.

LPG is odourless in natural state. An additive is added to provide LPG a characteristic odour. This is in order to alarm the user in case of a leak.

LPG is stored in the cylinder in 2 phases; liquid at the bottom and vapour at the top.
When you ignite the gas, you withdraw product in vapour form as the liquid is vaporizing inside the cylinder. The upright position ensures that the vapour remains at the top and the liquid at the bottom for safe use.

A blue flame indicates safe and efficient combustion, meaning that the gas is being burned efficiently and not being wasted. Blue flames are hotter and indicate more complete combustion.
