Is Vortex 95 Diesel Or Unleaded?

Unleaded 95 is a unique mix of gasoline developed to provide unleaded cars with a high-octane demand with high-octane, knock-free performance. Seasonally blended unleaded 95 makes it easier for autos to start.

What type of fuel is Vortex 95?

Vortex Premium 95 is a 95 octane Premium Unleaded Petrol using Caltex’s own advanced additive composition. It comprises a cleaning agent, a friction reducer, and a rust inhibitor, all of which are specifically designed to enhance and sustain performance.

What is Caltex Vortex diesel?

If you have an ancient diesel engine with a few miles on it and a lot of numbers on the odometer, it might be worth it to run a tank of premium diesel every now and then for a few additional cents per litre. The extra detergents, in particular, may be able to clean some junk out of your fuel system, allowing it to run more smoothly and efficiently. However, any useful evidence is anecdotal and reliant on claims made by the gasoline provider rather than reality or independent verification.

What type of fuel is RON 95?

There are several varieties of unleaded gasoline, as if there weren’t already enough options for driving your car.

All contain up to 5% bioethanol – with the exception of E10, which contains up to 10% – and are distinguished by their Research Octane Number (RON):

E10 (95 octane)

On September 1, 2021, this became the standard grade of petrol in the United Kingdom, with Northern Ireland following suit in 2022. See our helpful E10 guide for more information.

Super Unleaded (97/98 RON)

Some high-performance Japanese automobiles require the highest-octane fuel available, while others (such as Porsches) prefer it, albeit the benefits are small in most cases.

Premium fuels

Some stores sell their own high-performance, high-octane fuels, such as Total Excellium Unleaded and Shell V-Power Unleaded, both of which have the UK’s highest octane rating of 99 RON.

In Summer 2019, the labeling for unleaded gasoline (and diesel) was modified to comply with current EU standards rules. Instead of being referred to as “unleaded” or “diesel,” fuels are now identified by their biofuel blend (unleaded petrol is referred to as E for ethanol, and diesel is referred to as B for biodiesel) and biofuel percentage.

While all petrol pumps in the UK are required to adopt this style of labeling, shopkeepers frequently employ older designations alongside “unleaded” and “diesel” to aid motorists.

Is diesel gas or unleaded?

Depending on where you live, unleaded gasoline is referred to as petrol or gas. The term “unleaded” refers to standard gasoline; the term “diesel” refers to a whole different type of fuel. Unleaded fuel is used in petrol engines, which compress the gas and air before igniting the engine with a spark.

Can you use supreme diesel in a diesel car?

If you drive a diesel automobile, though, there’s no harm in putting a tank of super diesel in it every 1,000 miles or so. This should remove any greasy or sooty deposits from the engine and fuel system, allowing your car to run more efficiently and economically on ordinary diesel because the fuel system will be cleaner. In the long run, paying an extra 5-10p per litre for super diesel now and then could save you money in the long run if your diesel engine breaks down.

Owners of high-performance cars, including hot hatchbacks, may reap the true benefits of super fuels. While many of these automobiles will run OK on conventional gasoline, you should be able to tell the difference if you use high-octane gasoline. The most obvious sign of its value will be improved throttle response, while the engine should rev more freely and deliver greater power.

While some companies only use 97 or 98 octane fuel, you can find 100 octane gas at certain major merchants – even supermarkets – and while it will cost you a tenner per litre more than standard petrol, your performance automobile will profit tremendously.

Not only will your performance improve, but your efficiency may improve as well. Because high-compression engines are built to cope with higher octane ratings, fuel efficiency should stay the same, if not slightly better.

If the cost of high-octane fuel concerns you, there’s probably nothing keeping you from continuing to use conventional gasoline, but, like a diesel, your automobile will benefit immensely from a tankful of high-octane fuel every now and then.

Can I put unleaded 95 in my car?

91 unleaded The most popular form of fuel in Australia is petrol, which is available at almost every gas station. Most automobiles will be able to use it, though depending on your vehicle, you may find that premium fuel is more fuel efficient.

According to Fuel Watch, the national average price for ULP 91 at the time of writing is $1.40.

Premium, 95-octane unleaded petrol

Premium unleaded 95 petrol (PULP 95) is an unleaded fuel that is designed to be more fuel efficient while also causing smoother engine action, which increases performance. It is intended for use by imported and high-performance vehicles, however it can also be utilized by the vast majority of automobiles.

It is usually more expensive than ULP 91; at the time of writing, 95 was hovering about $1.60 per litre in most capital cities.

Premium 98-octane unleaded

Premium 98-octane fuel, often known as Ultra Premium unleaded petrol (UPULP), is the highest octane unleaded fuel, according to sources, giving more engine power and performance as well as less pollution. Performance cars, like PULP 95, make the best use of it, and some models may claim that they can only take PULP 98 and nothing else.

UPULP 98 is slightly more expensive than PULP 95, although there can be a significant price difference in other cases – the 98 pricing in most capital cities was roughly $1.70 per litre at the time of writing.


E10 is an ethanol-based fuel that contains 10% ethanol and 90% unleaded gasoline. It has a higher octane rating of 94, which may improve performance if your automobile is tuned for it. However, because ethanol has a lower energy density than oil, it may have a marginally lower fuel economy. By purchasing E10 fuel, you are helping to assist the Australian sugarcane or corn industries, which is a win-win situation.

At the time of writing, the national average price for E10 was only a few cents less than 91. To figure out which one is a better deal, you’ll need to see if the lower fuel economy is offset by the lower cost.

Are there different types of diesel in Australia?

However, this does not always apply to Australia. This is due to the fact that fuel is combined and distilled to varying standards and characteristics in each country. Previously, Australian diesel was harsh in comparison to European diesel, and European manufacturers claimed that the fuel prevented them from introducing their leanest, cleanest, and most efficient engines in Australia.

Since 2009, all Australian diesel has been ‘ultra-low sulphur,’ meaning it contains only 10 parts per million (PPM) of sulphur. We can run cleaner and more efficient fuels with ultra-low sulphur fuel, but the trade-off is that the gasoline has less lubricity. To combat this, ‘ULSD’ contains chemicals that aid in the process.

Where octane is found in gasoline, cetane is found in diesel. A diesel’s cetane rating indicates how powerful the ‘bang’ is; a higher number could give you a performance boost.

It’s easy to be duped into thinking that the ‘premium’ label on more costly diesels means they’ll give you better performance, but this isn’t the case. The cetane ratings of normal and premium diesel were the same in all three cases (BP, Caltex, and Shell). There was also minimal to no change in terms of lubricity or flash points.

The chemicals are what give the product its ‘luxury’ feel. There’s more to lubricity than just the addition… these are the most essential ones:

No, you shouldn’t put a spray of Dynamo or a spoonful of Cold Power in your tank. Special detergents are added to premium diesels that do not influence the fuel’s performance but clear deposits from your fuel injection system. The current injector’s extremely fine nozzles are the most prone to partial blocking, but rails and pumps might all use a good cleaning.

Steel is used in some fuel tanks, and a variety of metals are used in the fuel system’s pipes, fittings, joiners, and rails. Corrosion inhibitors are used to assist prevent corrosion and the difficulties that come with it.

Before taking on the Madigan Line, I remember filling up a diesel bladder at Mt Dare and attempting to get every drop into it. I’d just finished my 12th shower and was dressed in clean clothes that were supposed to last 4-5 days. The bladder then erupted in a flood of bubbling fuel, completely engulfing me. I’ve learned my lesson.

Premium diesels have additives that prevent foaming, making filling your tank easier and cleaner. Diesel did not always foam, but the introduction of biodiesel to the mix is to blame.

When you consider the few extra cents per litre it costs you versus the astronomical expenses of fuel system parts beneath your hood, premium diesel is definitely not a bad idea. At the very least, every now and again, run a couple of tanks of the good stuff to help clean the insides of your fuel system.

After a long vacation driving about and fueling up at isolated servos, I’d absolutely consider running a few tanks of premium diesel. Alternatively, if your diesel is subjected to a lot of stop-start driving and short excursions, premium can help to mitigate (but not eliminate) the issues that come with it.

What is the difference between diesel and brand diesel?

In comparison to normal #2 diesel, premium diesel has a higher cetane number, improved lubricity, and detergents that help clean injectors. For faster start-ups and less pollution, more cetane equates a shorter delay and improved ignition quality.
