Under normal circumstances, for fuel delivery, if you order during workdays by 12 PM, the product should reach your site by 5 PM the following workday. For lubricant delivery to Klang Valley, you should receive your products within 3 business days from the order date, and outside Klang Valley, within 5 business days, subject on stock availability. We also deliver on public holidays and weekends.

For fuels, we source our products from several oil companies to ensure that our prices are competitive. For lubricants, we are a “Master Distributor” for Chevron Malaysia Limited (Caltex lubricants) which provides lubricant products of the highest quality. To determine the actual cost involved for lubricants, overall factors should be considered, including downtime and maintenance costs, rather than just comparing prices per liter of various brands.

For Diesel

Biodiesel (or FAME) is a type of diesel fuel that is made from vegetable oil rather than fossil crude oil. FAME stands for Fatty Acid Methyl Ester and is produced via a chemical transformation of vegetable oils (e.g. palm oil, rapeseed and soy) into their corresponding esters. In Malaysia, the government specifies use of Biodiesel derived from palm oil.
The current diesel in the market is known as Euro 2M diesel which contains a max of 500 ppm sulphur level. With advancement in most machinery specifications towards Euro 5 standards, Euro 5 Diesel which contains a much lower sulfur content of 10 ppm was introduced to meet Euro 3 and above machinery specifications.
Euro 5 Diesel has a much lower content of sulfur compared to Euro 2 Diesel. This reduces carbon emission and thus results in less dirty smoke emission from the vehicles and machineries. Lower sulfur content also means a lower risk of developing sulfuric acid which would then lead to a longer life span of the machineries and improvement in combustion.

For Lubricants

Lubricants are often exposed to severe conditions while in use, such as extreme temperatures that necessitate that the lubricants remain in a fluid state even at these extreme temperatures. These conditions can cause degradation of the lubricant and damage to the metal surfaces through wear and corrosion.

Quality lubricants have an important role in the cost management of machines and engines. Proper lubrication ensures extended life span of the equipment and will minimize maintenance costs. To achieve these targets the lubricants must provide metal surface protection (wear inhibition and rust prevention), and cooling over a wide range of temperatures.

Most importantly, we need to apply the right oil at the right place, right time and for the right amount.

We need to give our machine or engine the best protection to extend its lifespan. We should compare lubricants in terms of their benefits to the machine or engine for the long term. Cost does matter, however cheap lubricants without enough protection will increase your repair frequency and downtime in the long run. Expensive lubricants might also not be necessary, and would depend on the requirements of the machine. We always advise our customers to use lubricants that at least meet the OEM advice.

Cost savings benefit calculator (example): 

Brand A Brand B
Cost of Lubricants RM X RM X+100
Running hours 500 600
Running KM 12000 14400

If X is RM 1000, then Brand B is 10% more expensive than Brand A. However, Brand B has a 20% longer life span than Brand A. At first glance, we believe Brand A is cheaper, but after a detailed comparison Brand B is cheaper due to its longer oil drain period.

This is a simple example that excludes the repair costs, spare part costs and downtime costs.
