Techron Fuels FAQs

Answer to your questions on

Why should I choose petrols with Techron ® over lower quality fuels?

Techron, the special ingredient in all Caltex petrols, makes them unsurpassed at keeping vital engine parts clean, helping your car perform at its best. Lower quality fuels can leave harmful deposits in your car's engine. As these deposits accumulate over time, your car may begin to hesitate during acceleration, knock or lose power. Petrols with Techron are unbeatable at cleaning up and avoiding deposits. There's no better way for you to protect and maintain your engine's performance than by using a petrol with Techron.

How are petrols with Techron ® different from other petrols?

Many other petrols use a detergent additive that's based on polybutene amine (PBA)-based chemistry. PBA additives do an adequate job of controlling intake system deposits–but only if the dosage in the fuel is high enough to do the job. In recent years, the concentration of PBA in many petrols has fallen so low that the petrols do not keep intake systems clean. And if a petrol uses a concentration of PBA-based additive that's high enough to keep the intake system clean, the additive itself can contribute materially to combustion chamber deposits. Excessive combustion chamber deposits can cause an engine to need a higher octane petrol to avoid knock or loss in performance. These excessive deposits can also cause higher tailpipe emissions. In contrast, Techron provides unsurpassed intake system deposit control, while simultaneously minimizing any contribution to harmful combustion chamber deposits.

Is Techron® good for your car?

Yes, and not just your car – but any vehicle you drive. This is because Techron, a special additive in all Caltex petrol, cleans deposits from your engine (that would have come from inferior-quality fuel) and prevents future build-up.

Is petrol with Techron® just a more diluted version of Techron ® Concentrate Plus?

No. While both based on polyetheramine chemistry, each is optimized for its particular application. Petrols containing Techron helps clean engine deposits left by low quality petrols and helps keep engines clean through regular use of a lower additive dose, while a bottle of Techron Concentrate Plus added to your fuel tank provides a quicker clean-up of deposits left by lower-quality petrol, through a higher additive dose.

Do I need to add a bottle of deposit control additive such as Techron ® Concentrate Plus to the petrol in my fuel tank?

If you regularly use a high-quality petrol such as Caltex, you probably don't need Techron Concentrate Plus. However, should you occasionally fill up with lower quality petrol, you may need Techron Concentrate Plus to help clean up deposits that can build up over time. In addition, if you have an engine that is sensitive to deposit formation, or if your vehicle is regularly used under severe conditions, you may also benefit from using Techron Concentrate Plus.

I care for the environment. Does Techron ® impact my car's emissions?

Deposits on carburetors, fuel injectors and intake valves can cause your car to produce higher emissions, which contribute to air pollution. Petrols with Techron are unbeatable at cleaning up and avoiding these deposits, giving you reduced emissions. And unlike the deposit control additives used by many oil companies, petrol with Techron cleans up intake system deposits while minimizing the contribution to emission-causing combustion chamber deposits.

My car is knocking and pinging. What is causing this? Can Techron ® help?

Knocking and pinging are generally caused by improper combustion in your engine. If the fuel-air mixture auto-ignites somewhere in the cylinder, the auto-ignition combustion wave can interact with the spark-initiated combustion wave, causing the vibration you hear as knock or ping. An increase in engine load, temperature, compression, spark-advance, air-fuel ratio and combustion chamber deposits all contribute to the tendency for an engine to knock. The use of higher octane fuel reduces this tendency. Deposits in the combustion chamber can increase you engine's appetite for octane by increasing the compression ratio. Fortunately, petrol with Techron minimizes any contribution to potentially harmful combustion chamber deposits.

What is Caltex Diesel (Bio) with Techron® D?

Caltex Diesel (Bio) with Techron® D is the only B7 product which contains the exclusive Techron® D additive to control deposits, help maintain fuel injector cleanliness and support optimum engine performance.

Can any motor vehicle use Caltex Diesel (Bio) with Techron® D?

Most diesel vehicles are able to run on B7 blends, as long as the biodiesel blend is produced by a reputable supplier, such as Chevron, and meets the Malaysian fuel standards. However, it is highly recommended that you consult your vehicle owner’s manual for specific information regarding which type of fuel your vehicle can take. You may also consult your car dealer or manufacturer for additional information.

Is there a need for any special modifications to be done to a vehicle’s engine system for it to be able to use Caltex Diesel (Bio) with Techron®D?

There is generally no need for any engine improvements or modifications. It is best to refer to Original Equipment Manufacturer (OEM) for recommendations.

Can Caltex Diesel (Bio) with Techron®D be mixed with other similar products and regular diesel?

While it is safe to mix diesel and biodiesel blends purchased from different suppliers and dealers, it is strongly advised that you use only Caltex Diesel (Bio) with Techron® to fully benefit from its cleaning and high performance qualities for your engine.

How do I ensure that Caltex Diesel (Bio) with Techron®D will work at its best with my vehicle?

Caltex Diesel (Bio) with Techron® D may be loaded into a vehicle’s fuel storage tank without draining the remaining diesel in it. But it is strongly advised that you use only Caltex Diesel (Bio) with Techron® D to fully benefit from its cleaning and high performance qualities for your engine.

Can Caltex Diesel (Bio) with Techron® D be used in motorboats?

Since there are many types and models of motorboats, advice and information must be sought from motorboat engine manufacturers or suppliers.

When and where will B7 Caltex Diesel (Bio) with Techron®D be available?

What is Euro4M all about?

As a regulatory change, oil companies in Malaysia are now required to follow the guidelines of the Euro 4M standard for RON97 petrol. Euro 4M is adapted from the European Union’s (EU) strict rules on fuel standards and specifications to manage fuel quality that have impact on the environment.

The main objective of the fuel standard upgrade is to improve emissions for better air quality. This also has to be done in unison with the availability of Euro 4 compliant vehicles.

Why is there a change from Euro 2M to Euro 4M?

The aim for the Euro 4M implementation mandated by the Malaysian government is to reduce exhaust emissions. This means lower levels of harmful exhaust emissions from motor vehicles and thus, cleaner and better air quality. This can be achieved via the introduction of the latest, most advanced emission control and engine technology that is available in Euro 4 compliant vehicles.

In the Malaysian context, the main difference between Euro 2M and Euro 4M standard fuel is the sulfur content which was significantly reduced from 500ppm to 50ppm.

What is the current fuel standard in Malaysia?

The fuel currently sold in Malaysia is of Euro 2M standard. With effect from 1st September 2015, the Malaysia government has mandated Euro 4M standard for RON97 petrol.

What is RON?

RON (Research Octane Number) is a rating of petrol. It determines the petrol’s ‘anti-knock’ quality or resistance to pre-ignition or detonation as it burns in the combustion chamber. Knocking is an abnormal combustion and should be prevented as severe knocking can be damaging to the engine.

What vehicle types are able to use Euro 4M RON97?

Most vehicles are able to use Euro 4M RON97. It is safe and requires no modification for existing petrol driven engines. However, it is best to refer to the Original Equipment Manufacturer’s (OEM) recommendation in your car manual or check the back of the petrol filler lid of your car for the recommended octane rating.

I am a RON95 consumer. Will switching to Euro 4M RON97 have an effect on my vehicle's engine?

If you’re driving a Euro 2M compatible vehicle, using Euro 4M standard petrol may have a small improvement in the emissions as the engine and after-treatment exhaust technologies are exposed to lower sulfur levels which can help improve exhaust catalyst efficiency.

Using petrol of a higher RON will not harm your car. You just need to find a suitable fit for your car and driving style. It’s best to refer to the Original Equipment Manufacturer’s (OEM) recommendation in your car manual or check the back of the petrol filler lid of your car for the recommended octane rating.

Should I empty my car's petrol tank before refueling with Euro 4M RON97?

Not necessary, you can top up with Euro 4M RON97 at any time.

Euro 4M RON97 Caltex with Techron is proven to keep your engine parts clean and performing at its best. Techron cleans the fuel injectors and intake valves and minimises the harmful deposits within the combustion chamber.

What is the effect on the performance of the engine if petrol of a different emissions standard and RON are mixed together? For example Euro 2M RON95 and Euro 4M RON97.

There is no issue if the OEM’s (Original Equipment Manufacturer) recommended RON is RON95. But, if the OEM’s recommended RON is RON97 and above, mixing different RON levels (RON95 and RON97) may result in a loss of performance.

Do I have to always pick the highest octane rating petrol for my vehicle? In this case, is it necessary for me to switch from Euro 2M RON95 to Euro 4M RON97?

If your vehicle is Euro 4 compliant, it would be advisable to use Euro 4M RON97 in order to enable the after-treatment technology and henceforth cleaner emissions.

Using petrol of a higher RON will not harm your car. You just need to find a suitable fit for your car and driving style. It’s best to refer to the Original Equipment Manufacturer’s (OEM) recommendation in your car manual or check the back of the petrol filler lid of your car for the recommended octane rating.

Does a higher fuel emissions standard with higher RON indicate a more environmentally-friendly fuel product? How about greater power?

Euro 4M RON97 will enable the introduction of Euro 4 compliant engines to the Malaysian market. Euro 4 compliant engines emit lower levels of exhaust emissions and that is good for the environment. Engine power output is a function of engine design, but continual use of Caltex with Techron will keep new and old engines clean to help ensure that engines perform at their best.

Why is only RON97 being upgraded to Euro 4M? Are there any plans to upgrade RON95 and Diesel?

As mandated by the Malaysian government, Euro 4M will be implemented starting with RON97 in September 2015. Any upgrade to other fuels will be announced by the government.

Do all of the Caltex stations throughout Malaysia sell Euro4M RON97?

Euro4M RON97 is sold at 294 Caltex stations in Peninsular Malaysia. Visit http://www.caltex.com/my/ to locate your nearest Caltex station.

What is Euro 5 diesel all about?

After the regulatory change government in 2015, all oil companies were required to follow the guidelines of the Euro 4M standard for RON97 petrol. In essence to continue improving emissions for better air quality, Euro 5 diesel is also being offered to the public as a voluntary product by the government.

Chevron and its brand Caltex is committed to ensuring our customers are equipped with the best fuel, hence we would like to make Euro 5 diesel product available for our customers at selected service stations. 

How is the new Euro 5 diesel different from the Euro2M diesel that is currently retailing?

The specifications of Euro 5 diesel and Euro 2M
diesel are similar, except for the reduction on sulphur content by a factor of more than 50 i.e. from 500ppm to less than 10ppm. 

My vehicle is not a Euro 5 standard vehicle. Am I still able to benefit from using Euro 5 diesel?

Euro 5 diesel can still be used on older vehicles but
there’s only slight environmental benefit as older engine technology inherently has higher emissions than new and advanced diesel engines that are equipped with ultra-low emission capability of exhaust after treatment technology. 

Euro 5 diesel can be used in conjunction with catalysts and particulate traps retrofitted and installed on older vehicles to help reduce smoke and particulates from these engines.

If I change to Euro 5 diesel, do I need to adjust the engine settings of my vehicle or do any retrofitting to my vehicle?

Engines that are in good mechanical condition and receive routine maintenance in accordance with manufacturers’ recommendations will not require any adjustments in order to use Euro 5 diesel. 

Can Euro 5 diesel reduce black smoke occurrences?

Black smoke is among the most common smoke
issues for diesel vehicles. It is emitted from a diesel vehicle caused by an
air-to-fuel ratio that is unbalanced. The smoke contains particles such as
carbon and soot that are not being burned as fuel. 

Euro 5 diesel will not make significant changes to existing vehicles with black smoke problems.

For well-maintained engines, replacing the current grade of Euro 2M diesel with Euro 5 diesel will help to further improve our air quality.

Euro 5 diesel will make exhaust after-treatment devices more effective. When the device is installed on an engine, we can expect lower emissions and less particulates compared to older vehicles. The best way to keep smoke levels down is to operate a well maintained engine and not to overload it. 
  

Does Euro 5 diesel cost more than Euro 2M diesel? And if so, why?

As Malaysia operates in a ‘managed float’ system, the pump prices are determined by the government each month based on global oil prices and other factors.

At present, Euro 5 diesel is higher by RM0.10 per litre than Euro 2M diesel as permitted by the government.

What is the effect on the performance of the engine if two diesel of a different Euro standard are mixed together? For example, Euro 2M diesel and Euro 5 diesel.

Drivers can mix Euro 5 diesel with the existing diesel during the initial phasing in of Euro 5 diesel. But once the vehicle is on the run with Euro 5 diesel, it is advisable not to switch back to high-sulphur diesel as it might reduce the effectiveness of exhaust after-treatment devices sooner than later.

Will Caltex have both Euro 2M and Euro 5 diesel at all retail outlets for my choice?

Euro 2M diesel will be available at all retail outlets, however only selected stations will be offering both Euro 2M and Euro 5 diesel simultaneously.  

How can I assure the diesel you sell at your service stations is Euro 5 standard?

Chevron has stringent procedures to ensure our
products are on specification.
