You don't need premium diesel as all diesels meet standards, but premium fuels contain additives that can clean injectors, reduce foaming, and potentially benefit older engines or heavy users, though performance gains are minimal; for newer cars, it's mostly for keeping the system clean, while older ones might see more benefit from the detergents, balancing cost against potential long-term fuel system health.
Therefore, if you drive a sports car, to help maintain its performance, it may be worthwhile using premium. On the other hand, if you drive an ordinary vehicle, it will be unlikely that you will see a noticeable difference. Therefore, regular petrol or diesel is frequently the more popular choice.
So, is it worth it? Looking at the extra few cents per litre it costs you, compared to some extraordinary costs that fuel system parts cost under your bonnet, the premium diesel probably isn't a bad idea. At least run a couple of tanks of the good stuff every now and then, to help clean the insides of your fuel system.
Yeah, you can mix any kind of diesel without worrying. Even premium diesel with regular diesel.
Ampol claims it's Amplify Premium Diesel has “unique, advanced additives” that will “restore and maintain fuel injector cleanliness.” They say that with regular use it will “protect your engine and provide up to 100% power restoration.” They also add a caveat that the results may vary “depending on the engine, ...
Premium diesel is formulated with additives that enhance lubricity and protect critical moving parts within the fuel system. By reducing metal-to-metal contact in key components, premium diesel helps extend engine life and lower maintenance demands.
– The easiest way to ungel diesel fuel is to get the vehicle into a normal temperature zone. You can push it into a heated garage or simply wait for the temperature where your vehicle is parked to rise. The fuel will return to normal naturally.
Diesel. If you have a diesel vehicle, your choices are limited to two grades – standard and premium – and all diesel vehicles can run on the former. But, as with petrol, there are benefits to balance out the extra cost of a higher-quality blend at the pump.
Premium diesel fuel offers advantages over regular diesel. It contains additives that improve engine efficiency, reduce wear, and keeps the fuel system clean. Additives create better combustion, leading to improved power, smoother engine performance, and better fuel economy.
Why is Ampol Amplify Diesel considered a premium fuel if it's the same as regular diesel? Amplify Premium Diesel contains an advanced multi-function additive that includes a cleaning agent and rust inhibitor which clean and protect your engine as you drive.
The simple answer to the question of 'what diesel should I use? ' is 'any' and that the base used for all diesel in Australia is the same blend and will run the same, regardless of what vehicle you drive. The difference is in additive packages that are put into the fuel.
Summary. Sales of new petrol and diesel vehicles are being banned in the ACT by 2035. ICE vehicles are being phased out as manufacturers pivot to making EVs and lenders stop offering loans for them. Driving and refuelling your petrol car beyond 2035 will still be possible.
You should buy a diesel car in 2025 if you do high-mileage, long-distance driving or need heavy towing, as they offer superior fuel efficiency and durability for such tasks, but it's less ideal for short city trips where hybrids/EVs are better, and you must consider potential future urban restrictions and the ongoing maintenance of complex emissions systems (AdBlue, DPFs). While new diesel production is slowing, modern diesels are cleaner, but consider used Euro 6 models or leasing (PCP) to mitigate depreciation concerns as the market shifts towards electrification, with bans on new sales generally targeted for 2035.
According to the Federal Trade Commission (FTC), higher octane fuel provides no benefit for vehicles that don't need it. It won't make your car run cleaner or go faster. If your owner's manual recommends regular gasoline, it's best to fill the tank with regular fuel.
There are other benefits to Supreme+, including less wear and tear, a clean fuel injector, better protection from corrosion, and less chance of clogging. It also helps the fuel burn more efficiently so you get better fuel economy†.
Diesel #1 is also known as winter diesel because it performs better than Diesel #2 in cold temperatures. It has a lower viscosity and is not prone to gel in freezing temperatures. Most stations offer a premium Diesel mix that is blended for local weather conditions.
Using a premium diesel will flush through the car's fuel system and engine to remove the likes of soot, oil or carbon build-up.
The "holy grail" of diesel engines typically refers to the Cummins 5.9L 12-valve (6BT) for its legendary reliability, mechanical simplicity (P7100 pump), and immense performance potential, making it iconic in the truck world, while modern contenders for a "holy grail" include the LBZ Duramax for its power and pre-emissions design, and innovative clean diesel tech from companies like Bosch.
If you put 91 octane fuel in a car that requires 95 (or higher), you risk engine knocking (pinging), which can cause power loss, poor acceleration, reduced fuel economy, and, if done long-term or under heavy load, potential engine damage, as the lower octane fuel ignites too early under compression, but modern cars with knock sensors can often adjust timing to prevent immediate harm, making a single mistake less critical than continuous use.
Premium diesel does cost extra but enhanced efficiency helps counterbalance the cost. Detergents and lubricants help keep the engine clean and reduce friction, benefits that can improve fuel economy.
Premium diesel is only really worthwhile if a vehicle has had the chance to accumulate sediments within the engine. If not, then you probably won't notice too much of a difference when using premium diesel and it's considerably more expensive at the pump.
No problem at all. That's why even the manufacturers say that you will need at least 2 tank full of the premium fuel before you start seeing results. This is because you need to use up all the regular diesel in the system and it has to run only on premium fuel.
The worst things for a diesel engine involve neglecting maintenance (especially oil/filters), using poor fuel quality, allowing low fuel levels, overloading/lugging the engine, and not letting it warm up/cool down properly, all leading to contamination, excessive wear, turbo damage, and injector/pump failure due to high pressures and sensitive components. Contaminated fuel (water, dirt, high sulfur) is especially damaging, corroding parts and clogging filters in these high-pressure systems.
The Effect of Idling on Diesel Fuel
Idling is ineffective to prevent fuel gelling for multiple reasons, including: Limited fuel circulation: When idling, engines experience limited fuel circulation, resulting in an insufficient blending of warm and cold fuel to raise the temperature throughout the system.
As the temperature drops, diesel fuel begins to take on an opaque and viscous appearance that indicates the onset of the gelling process. Diesel must remain at temperatures below -10 degrees Fahrenheit for roughly 48 hours before it gels completely.
