Are the prices competitive?

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 Lubricants

How do we give our machines maximum lifetime by applying lubricants?

Lubricants are often exposed to severe conditions while in use including extreme temperatures that necessitates 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 thru 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 right amount.

Does cheap lubricants provides cost savings or is expensive lubricants the best?

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 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.

Can we mix the different brands of lubricants but with same lubricant properties?

This depends on the current oil that you are using and the oil that you want to change to. It is hard to conclude without knowing exactly the characteristics of both oils. The most common, safe and simple way to change any oil is to drain off the old oil, and then flush the machine with the new oil, and lastly fill in the new oil.

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 detail comparison Brand B is cheaper due to its longer oil drain period.

This is a simple example without including the repair costs, spare part costs and downtime costs.



For Tyres
Click on the questions below to see their corresponding answers.

How frequent should I inflate my tyres?

It is very important to check your tyres' inflation at least once a month with an accurate tyre pressure gauge, if you are frequent traveller, then we advise you to check every 2 weeks. Under-inflation or over-inflation can cause abnormal, excessive wear and tear, which in turn can cause tyre overheating, fuel overuse or even something as dangerous as a tyre failure. Be sure to check the pressure while your tyres are cold and have not been used recently.

What makes up the price of a tyre?

Tyres are complicated technical products and tyre manufacturing requires massive investments in product development and production. The majority of the price of the tyre is because of the raw materials used and the manufacturing labour costs.

Is there a manufacturing date on tyres?

On all branded tyres, a four-digit-code shows the year and week when the tyre was manufactured. The manufacturing code has four digits, for example, the code 2111 means that the tyre was manufactured in week number 21 of the year 2011.

Does tire pressure really impact fuel economy of a vehicle?

Tire pressure can greatly impact fuel mileage. The correct tire pressure is a delicate balance between tire performance, tire life, ride, safety, and rolling resistance. The lower the rolling resistance the tire exhibits, the higher the fuel mileage. However, less rolling resistance also means less traction. Underinflated and overinflated tires can be dangerous. Purchase a high quality tire gauge and check your tires every time you fill up with gas. Inflate to the maximum pressure as designated on the tire placard usually located on the driver's door or door post.

What does it mean when tires are cupped?

The tread on the tire has abnormal wear. Cupping can be caused by improper tire balance, weak shocks or struts, or other worn suspension components. This abnormal wear occurs when the tire bounces slightly as it is rotating down the highway. To check your shocks and struts, complete a bounce test on the car. Push down on the end of the car that the tires are wearing abnormally and see what happens. The car should bounce back up and stop bouncing. If the car continues to bounce more than twice, the shocks or struts could be worn. Check both the front and back of the car. Remember to rotate tires every 7500 miles to maximize their life.

I recently had four new tires installed on my car. The tires lose about 8 psi per week. Where do you think they are leaking and how can I tell?

The bead, where the rubber contacts the wheel, may be leaking on each tire. The best way to look for leaks is to put about a teaspoon of dishwashing soap in a spray bottle and fill with water. Spray the tire, rim, valve stem, and valve core with the soapy solution. As you spray the tire you will see many bubbles from the soap, but look carefully. Eventually the leak will start to blow a pile of bubbles. If the bead is leaking, you can have each tire broken down and the bead cleaned. Then the tire shop can use a special bead sealer to seal the tire.

Should I get my tires rebalanced every time I have them rotated?

You should get your tires rebalanced if you notice vibrations or if the tires are wearing abnormally. You should also get a tire rebalanced if it has been removed from the rim during repair. But to have the tires rebalanced every 7500 miles probably is not cost effective depending on the price of the tire. If you do not notice any vibrations or abnormal wear I would only recommend getting the tires rebalanced in the middle of their life - often this is at the 30,000 mile interval. And next time you buy a set of tires, look for a tire company that gives free rotations and balancing for the life of the tires.

How fast can you drive on a temporary spare?

Most temporary spare tires are designed for a maximum speed of 50 mph. Only use this type of tire to reach a facility that can repair or replace your original tire. Before returning your spare to the storage location, check the air pressure. It is common that the air pressure in a temporary spare is higher than in your regular tires. Always read the owner's manual and tire sidewall for specific information.

What may cause my steering wheel to pull to the right while driving?

Your car is most likely out of alignment. Incorrect alignment reduces tire life and can cause unsafe driving. You should take your car to a tire shop or service center that specializes in wheel alignments. Correcting the alignment will increase fuel economy, improve handling, and extend tire life.

My mechanic told me that my new tires had radial pull. He cross-rotated the tires and the pull went away. What is radial pull?

Radial pull can be caused by a defective radial tire construction or uneven tread wear. A misalignment of the belts inside the tire can cause a new tire to pull in one direction. Moving the bad tire to the back reduced its effect on steering. You may want to check into having the tire replaced under warranty.

When I parallel park, I sometimes hit the curb. Will hitting curbs cause damage to my car?

Running into a curb could change the wheel alignment, loosen wheel weights, and damage the tires. When parallel parking, you should stay six to twelve inches from the curb. If you do hit the curb and then notice your steering wheel pulling one way during regular driving, have the alignment checked.

After skidding to a stop with smoking tires my car now vibrates especially at higher speeds. What's wrong and how can it be fixed?

You probably flat-spotted your tires. During brake lockup, the tires wear on one spot. The tire gets out of balance and out of round when there is less tread on that part of the tire, causing the vehicle to shake at high speeds. You may need to replace the tires.

Do you recommend using liquid tire sprays to fix a leaking tire?

I would only recommended using liquid tire sprays in emergency situations. The liquid can corrode the inside of the rim and throw the tire off balance. A better fix is to have the tire plugged or patched. A technician can plug a tire without removing it from the rim. However, when a tire is patched it needs to be removed from the rim. Always have the tire and wheel assembly rebalanced if the tire was taken off the rim during the repair.

My mechanic told me that I should rotate the tires on my car. What is the benefit of rotating tires and how often does this need to be done?

Rotating increases the life of the tires. Tires can wear differently from side to side and from front to back. Rotate tires every other oil change or at 7,500 mile intervals to even out the wear. Look in your owner's manual for specific procedures. If frequently rotated and properly inflated, tires should last about 50,000 - 60,000 miles.

Should an alignment be part of regular maintenance?

I recommend getting an alignment when one or more of the following conditions occurs: the vehicle hit a curb or other obstruction; steering wheel is pulling one way or another; one or more tires are wearing abnormally; when replacing the tires; after an accident or going in the ditch; and, when suspension or steering components have been replaced. The correct alignment will increase the life of the tires, increase fuel economy, and provide for safer driving.

What do all those numbers mean on the sidewall of the tire?

Here's an illustration that should help you gain some important knowledge about your tires.



1. P indicates a passenger (car-type) tire.
Other options would be no P indicating metric sizing (essentially the same as P-sizing, which has its heritage in Europe) or LT for light truck. LT tires are designed for heavier loads and more rugged service conditions.

2. Width of the tire, in millimeters.
The higher the number, the wider the tire.

3. Aspect ratio.
The height of the sidewall section compared to the width of the tire. Example: If this number was a 50, then the tire section is half as tall as it is wide. Short sidewalls deliver crisp handling. Tall sidewalls give a smoother ride. For a specific tire width, the smaller this number, the shorter the sidewall.

4. Construction.
R indicates radial construction. Unless you specify the other option, bias (which would have a D [diagonal] or B [belted bias] in this position instead of an R), you are purchasing a radial tire.

5. Wheel Size Designation.
In simple terms, this indicates the distance across the "doughnut hole" of a tire. You must match wheel diameter and the tire opening. A tire with a 15 size designation will not work on a 14" wheel, and vice versa. Improper matching of wheel and tire size can cause serious injury or death during installation.

6. Service Description.
Includes the load index (a number) and a speed symbol (a letter). About load index, remember: keep the number the same as or greater than the original tires' load index. That number stands for a specific weight carrying capability. Key is that the higher the number, the greater load carrying capacity. So keep the number the same or higher, because your tires are matched to the weight of the car. Never choose a tire with a lower load carrying capacity than the original equipment tire size.

As for the speed symbol, it means the tire is speed-rated on an indoor test wheel to the following speeds:

N = 87 mph U = 124 mph
P = 93 mph H = 130 mph
Q = 99 mph V = 149 mph
S = 112 mph Z = 150+ mph
T = 118 mph W = 169 mph
y = 188 mph

We recommend that the replacement tires match the speed symbol of the original tires since these match the speed capability of the vehicle.
