Aspen 4 Fuel. A Closer Look...

I Take a Closer look at the Advantages that far outweigh the extra cost.

Aspen 4 alkylate 4-stroke petrol.

Aspen 4 is the cleanest petrol that you can use.

Aspen is made from alkylate petrol which is made from the gases from the top of the distillation tower which are synthetically modified into a liquid again.

The result is;

A petrol that is virtually free from sulphur, benzene and aromatics (solvents)
is Ethanol free
is chemically inert - can leave the fuel in machinery and will start easily next time.
A low odour - you are breathing much cleaner air, when working with your powered machine.

Use Aspen 4 and you will discover a much cleaner and more environmentally way to cut your lawn, or ride your motorcycle, without the need to change your petrol mower,or catch a bus.

Safety data sheet: SDS-UK-Aspen_4-140415.

And a cleaner and better way to look after your

"Classic Britshock" trials motorcycle.

This is what Ian told me yesterday ..

 (BSA "Otter" Trials Bikes)

But the real reason for the email is that since Feb I have been running with a new concentric and Aspen fuel and the last time the bike was used was March.

Once the forks were done I switched on what fuel was left, flooded the carb and gave a lazy kick, one more proper kick and she started and ticked over like a sewing machine (British)...
Before using this fuel it would have needed a carb strip and the extra cost is worth not having to go through that each time. It also seems to run better, but I am not one to keep playing with carbs as long as it starts and keeps going all's well.

Best Regards,

Ian.

Charlie~Oo>  Well as you know, most of my BSA "Otters" are fitted with my own Glass-fibre tanks,

I just love the shape of the design and have done so since the first one I saw of Ray Small's,many years ago.

I have made a couple using Vinylester resin  and bought one from Sammy Miller Products.

But the rest are just made from Polyester, that I did not get around to lining at a cost of £40 a tank.

So with Aspen not effecting even this resin, It is good news to me.

I made a tank and put Aspen fuel into it after only a weeks curing, and there seems to be no effect on the resin whatsoever.

Tank Blue, picture. 

Then we get to the carburettor situation.

I spent a merry day with a couple of my guitar strings cut from one of my guitars, and with a pair of magnifiers on instead of glasses  proceeded to try and unblock the bushed pilot jets on all three carburettors.

The white crud caused by the corrosion on the zinc based metal by the ethanol pump fuel, was more than difficult to remove. And the carbs really wanted placing into a Ultrasonic  cleaner to make sure evey last bit of crud is removed. And this every time you forget, and leave Pump-fuel in your motorcycle fuel system.

And two of them had been started earlier in the year.

I have no proof to speak of but striping most of the engines used over the last few years, I have found that this white powdery corrosion is on most parts of the upper engine.

And I am sure this is one reason why we suffer from sticking exhaust valves which in the end seize to the guide them self...

There are 270 stockists of Aspen fuel across the UK ...  so you should really find one that is not far from you, and another advantage is that it comes in its own sealed can that can be used again for other purpose 

To save me overstretch this page just go to the Aspen fuel web site and look for your

Nearest Stockist There.    Or just   Google, "Aspen  fuel" for result.

A report about using Aspen 4T fuel in your "Classic Motorcycle".

One of the biggest issues facing the collector of Classic Motorcycles is the quality of modern petrol. The petrol that we buy from the filling station today is quite poor quality compared with a decade or so ago.

Oil companies are under more and more pressure to extract more fuel from every barrel of crude, which is leading to a poorer quality fuel.

This modern petrol is made up of more than 100 chemicals, roughly a third of which are Aromatic Hydrocarbons (solvents).

It is these solvents that give petrol its signature heady smell, but these chemicals are also responsible for the rapid degradation of the petrol.

At times this fuel can degrade to an unacceptable level in as little as a month, after which time the ability to start an engine will be compromised, and power will drop off when started.

The stale fuel also starts to slowly eat and dissolve soft materials such as Rubber fuel hoses,Plastic  and Polyester fuel tanks and Aluminium and Zinc carburettor parts.

The safe storage life of 'pump'-petrol is now only around one month.

Although the actual rate of degradation depend on heat, light and humidity.

Storage of cans in a cool, dark and dry cabinet will extend the life of petrol, whereas the fuel in the tank of a motorcycle kept near the window in  summer,or a warm garage in winter will degrade the very fastest.

Oil companies are also now having to add a percentage of ethanol (bio fuel from a renewable source) to petrol to make it go further, preserving underground oil reserves for a few more years, a noble cause.

However, the ethanol has an affinity to water and absorbs "its own equal volume in water", with which it mixes and forms a watery mess in the bottom of the tank, which eventually turns to a gel in a process known as phase separation.

Many Classic Motorcycle owners run their beloved machines much less often than they wish they could.

Pressures on time from other commitments leave much less free time than we thought we would have when we first bought or built our bikes, leaving us less time to use them.

The result is that our bikes sit being unused for lengthy periods, and of course the fuel tanks often tend to be quite large, so we don't drain them out between use.

And of course , these days we tend not to turn the fuel off and let the engine run dry like we used to, so fuel remains in the carburettor, doing what fuel does best, going stale, and even if we do make an effort to drain every thing down, the residue in the carb still corrodes especially the zinc based carbs.

So when we do at last get a chance to use our beloved motorcycles we find the engine will not start, or if it does then it runs like a bag of proverbial nails.

The bike is posted off to your friendly mechanic if you have not got the time to sort the job yourself. and the phone soon ring with a list of parts that he thinks is needed to get the bike running right again and it is usually the carburettor that is the number one item on the list.

But there is now an answer to this problem in the form of Aspen alkylate fuel. This is a chemically pure form of petrol made from the surplus gases at  the refinery, and contains no Ethanol or other solvents.

The result is that Aspen can sit in the can, or in the bike for years with no detriment to the carburettor,or fuel lines , ensuring a good  start every time, even after many months of storage.

 Bikes stored with Aspen fuel still in the system will start easily even after months (or years) of storage and furthermore, they start cleanly and sweetly with none of the coughing and  spluttering , or the clouds of smelly exhaust gasses that we are all used to with pump petrol that has been around for more than a month or so, you will still get the need to pump the oil from the sump with some models that are prone to "wet-sumping" though....

The engine oil will stay perfectly clean when using Aspen as it does not have to clean up the filthy products of combustion associated with pump fuel, and the spark plug too, will remain virtually untarnished.

The upper cylinder of a new engine run on Aspen from new will look just like new, if dismantled after several years of use.

Where-as one run on 'pump'fuel  will have heavy carbon deposits, but when used exclusively running on Aspen these old carbon deposits will slowly and surely diminish.

These benefits alone will to some extend and counter the extra cost incurred by the use of Aspen fuel.

Even though Aspen is some 2.5 times the cost of 'pump'fuel its a cost that Aspen users are more than happy with to ensure that their motorcycles suffer no further deterioration.

And to be honest it should be used, just for peace of mind, now knowing what is eating into your investment, on any Classic Motorcycle engine.

Big Leap Forward.

Hi Chris.

"See The Light".

02/01/2020...

Since 2016. I have used nothing else but ASPEN 4T in any of the bikes we own..

 My brother has a large contract for an international company in London.

 And part of this contract is to provide generating and snow clearing equipment powered by small four-stroke industrial engines.

The bill every year to keep these serviced and running properly was astronomical, and caused by one problem, the fuel used in these machines that was left in for months on end, when the equipment was not getting used. We don't have snow every day, or ice, here in the UK...

 So something radical needed-doing the labour involved in keeping these machines ready to roll was astronomical too, and like all good farmers only done at the last minuet...

 So when they were put into work the trouble still appeared, and long trips back and forth from Warwickshire to London on a daily basis, was more than a nightmare.

 Don't forget that I had decided to use Aspen at this time, so suggested that this fuel was used in these machines... The cost of it was considered for a while , but brother could see the sense of giving it a go, and persuaded the clients to go along with what we had said.

Now Four years later all of the fleet of these standby machines are running on Aspen 4T fuel... They are serviced but the fuel is usually left in them. And most start second pull after standing since the last winter...

 So not only all of the bikes in the collection, including ALL of the "Otter's", and now this fleet of stand-by equipment, only ever get used with ASPEN 4T fuel in them...

No I really don't get paid a penny by ASPEN ..Honest...

I just like an easy life...Don't make work when there is a way to avoid it...
