You guys are now suffering something that has been affecting owners of vintage machines with glass fibre tanks and non ethanol resistant steel tank liners for quite a while now. It means that the ethanol issue is becoming a safety issue in even comparatively modern vehicles. Thats bad for you and us but might in ther long run mean we can do something about this issue instead of just having to suck it up. When ethanol starts affecting cars too then the fuel companies may be forced to stop diluting fuel with ethanol. Or find another less destructive additive.

I looked at this when I first started worrying about ethanol damage and came across this suitable liner from caswell

http://www.caswellplating.com/aids/epoxy...

However given the quote from the Triumph manual, in my previous post on this thread, regarding the suitability of their tanks for petrol containing up to 10% ethanol. Can anyone state conclusively that the deformity is due to ethanol based fuels??

According to internet information I can find Tesco use 5% ethanol based fuels and the current UK max unless the fuel is advertised as such seems to be 8%. Well within Triumphs stated limits.
If it can be proved ethanol is causing the deformity then it would seem that Triumph have hung themselves on their own statement. Of course the probability exists that fuel companies are padding out stocks with more than 10% but would they really risk that??

So if its not ethanol then what else could it be I don't want to spend the time, money and effort on future proofing my tanks with a liner if its something else thats causing the deformity

Ducati have the same statement. It may have been valid (or valid enough) based on experience known with ethanol in fuels.

Or the tank is considered to be a consumable item..just lasts a bit longer than a light bulb or oil filter.

However even my lightbulbs are ageing better than the tank. No matter the cause, the symptoms and consequences are what counts.

Hi ALx

Yes I agree that if the tanks are deforming whatever the cause then Triumph have a case to answer. The thought of the tank as a service replacement item did make me laugh, 6000 oil, 6000 oil filter, 12000 air filter, 30000 tank.

Hower I just wanted to avoid time and expense coating the inside of the tank if ethanol isn't the cause.

if ethanol isn't the cause, then it's either sunshine, air, cold, heat, earth's rotation. The most likely culprit is something in the fuel that is in contact with the inner surface of the tank.

Instead of coating the tank, at least take measures to minimise/eliminate secondary effects of an expanding tank..ie stress relief. Drill holes or an expanding tank will have nowhere to go except bend/warp.

It's water - the ethanol is merely the attractant that pulls the water out of the atmosphere. So Ethanol is indirectly the catalyst that creates the issue.

Summary: E10 and E20 formulations of petrol/gasoline deform various plastics, including those used in the automotive industries.

Okay Alx thats a wee bit of a generalisation of the summary, below is a list of the plastics that were actually tested in E10 (10% ethanol mix), E20 (20% ethanol mix) and ordinary fuel. Below that is the summary of findings. Now does anyone know which Plastic the Triumph tanks are made of??

Cheers

Fent





ABS Acrylonitrile Butadiene Styrene
PA 6 Polyamide - Nylon 6
PA 66 Polyamide - Nylon 66
PBT Polybutylene Terephthalate
PET Polyethylene Terephthalate (Mylar)
PUR Polyurethane
PVC Polyvinyl Chloride
PEI Polyetherimide (GE Ultem


PA 6, PA 66, PET, and PEI, were compatible with the three fuels. The other four materials, ABS, PUR, PVC, and PBT, were affected by all three fuels to varying degrees.
The ABS specimens failed after less than one week of immersion in all three fuels. The specimens turned to a jelly-like mass in the bottom of the jars. This material was not compatible with any of the fuels. Finally, no automotive or small engine fuel system applications of ABS could be located, quite possibly due to its incompatibility with fuel.

In each case with PVC, PUR, and PBT both E10 and E20 caused large enough changes to raise a concern. Because of this, these materials would be a poor choice for use with either E10 or E20. Finally, no fuel system components made of either PUR or PVC could be located.
Different degrees of discoloration were observed in many of the other test samples, slight yellowing of plastics occurred on a few samples with E20 causing more yellowing. Samples were marked with an engraver for identification purposes. All can still be easily read with the exception of the PUR sample immersed in E20. Discoloration does not mean a failure in an automotive fuel system component

PA6

Note that the test says nothing about water
- fresh gas with no water absorption in the alcohol = no issue (which is what test found)

PA6 for the tanks. Note the report states "compatible" without defining what that means, apart from observing there's not much other literature to go on. Some of the literature also refers to using synthetic ethanol..lab studies do not always equate to real-world experiences, as many Ducati owners can attest to.

Perhaps the conclusive "significantly different" is the measure of compatibility..and industry standards.

For example, PA6 (delta-volume and delta-mass) when exposed to either E10 or E20 (almost the same amount) was increased by around 10%.

10% volume change may be acceptable for some applications but that's a problem where that expansion occurs between constrained mounts, joints or threaded components.

eg. experiences by Yamaha with fuel filters on outboard motors..only way to change the filter is to bung the module in a freezer as the threads have seized.

I think the tanks are not just bung-PA6-in-a-mould but are layered with various PA6 concoctions/grades according to function (eg the PA6 on the outer/paint side is different from the PA6 on the inner/fuel side).

PA6 is supplied by manufacturers in various grades according to function.

eg. some BASF grades:- http://iwww.plasticsportal.com/products/...

Again, the critical component is the water - the 'aggressive' alcohol blend in that paper contained total water by volume of <0.1%.
One critical factor of water in E10 is that it will phase separate at levels of 0.5% at ~ 50 deg F and the alcohol/water will no longer be in a homogeneous mix and will settle out into distinct layers at the bottom of the tank. (higher temps will actually support more water in suspension, lower temps will be less - note that the controlled environment was at a whopping 55C)
The tests only prove what happens with a relatively water-free sample - real life situation, especially in high humidity & cooler environments (i.e. winter!) lead to real problems with the alcohol literally wicking the water from the air and leading to the phase separation.
They need to repeat their tests with higher water content & see what happens then!!!

This is what phase separated E10 gas looks like:

I just pulled this sample from my lawn tractor - which ran like crap last time I used it. Pretty obvious why!!

You should be able to clearly see the delineation between the ethanol/water at the bottom and the (cloudy) gas above it.
(after it was left for a while the cloudiness dissipated - obviously was more water that eventually sunk to the bottom)

http://www.triumphtorque.com/media/file/...

There are products which help prevent phase-separation from occurring - K100 is a popular preventive product - http://www.k100fueltreatment.com/main.ht...
But it will not reverse the process once the gas has separated.

There is only one product that will reverse - HydroBurn from Cim-Tek.
CimTek actually provides products to the gasoline industry - filters etc.
http://www.cim-tek.com/petroleum/additiv...

Here are some videos that show how the HydroBurn and their Industrial equivalent PSR are effective.

http://www.youtube.com/watch?v=XljQdR-av...

http://www.youtube.com/watch?v=oWl8odEwH...

Here's a post-script:

I went back out & pulled the hose off the tank feed to the carb and drained some gas directly to the bottle.
This is all obviously from the bottom of the tank - astonishing!

Would this then indicate that bikes which stand for lengthy periods with ethanol blended fuels in their tanks are going to be more prone to the dimensional changes or blistering experienced by some owners than those which are used regularly??

I reckon that could be true. Moral of the tale. Drain the tank if you only ride on sunny days or if you are laying the bike up for extended periods. If that much water is getting into tanks we're going to see rust problems on relatively new metal tanks soon I reckon.

This is fascinating actualy. IO knew there was an ethanol problem but not why.

Wow. Thanks for a very graphic demonstration.

The last time i swapped the fuel filter on my sprint I was amazed that a mugful of water had got in through the filler cap, after all even with the drain blocked it only gets in when you open the cap. This appears to explain where that mugful came from

I've read some american accounts of that already, they have more ethanol in fuel than us.

Its certainly going to mean future 'barn-finds' will need new tanks

Exactly. Some of the biggest problems are seen on snowmobiles in N.US - three reasons, they sit for about 8 months, there is high humidity and the temperature is obviously very low in Winter. At low temp the fuel will hold less than half the water that it would in warm summer temps and so separates with much less.
Boats are also big issue - again the seasonal use (opposite of course) and the obvious access to water!

Anthony Lovell:

Definitely! - if the has is turned over regularly, that is the best prevention. And of course if you don't use Ethanol Gas to begin with!!! :lol:

nickwiz:

Recognize that if you do get separation, the water goes to the bottom.
You need two things for rust - water & oxygen. OK - three things - metal too! :lol: There's no oxygen so rust should no be a huge issue.

ethanol attracts water.

plastic absorbs water

plastic expands.

Deformations occur depending on the form of the plastic. Plastic can also deform if constrained by fixed mounts and trying to expand due to water.

The K100 will definitely help prevent phase separation - if it has already happened the only product that will reverse it is Cim-Tek HydoBurn
K100 will not recombine the Ethanol/water into solution.

i.e. in order to be sure that there is not any separated water in the bottom of the tank before you start using something like K100 product, the only alternative other than HydroBurn is to drain & dry first, before starting again with fresh gas & treatment additive.

The only thing I am not clear about in this regard is with the water, as long as it remains in suspension (with or without additive), how does that affect the impact on the PA6 tank? These products are designed just to ensure the water is carried through the combustion process, not designed for the 'protection' of the plastic tank (which is not even a consideration for them generally)
You might expect though, that as long as the water does not separate out into a concentrated pool, that it's dispersal throughout the gas would limit its contact area?

I'm thinking of doing all my major servicing over winter this year including valves etc, so will probably have the tank off for a long while.

Is the warping also noticed when off the bike when its no longer held in position by the mounts?

Just wondering on the best way to store it, will drain all the old fuel out of course.

After corresponding with K100, it now seems that K100 will also reverse Phase Separation that has already occurred - so above statement is incorrect. I originally attributed that to a (2 year old) forum post by their former President declaring as such and the web-site also states same.
Current President states that in dose of 3x K100 to displaced water will combine with the water and allow the alcohol to go back into solution. The web-site has yet to be updated on this feature (in the FAQ)

06 955i Daytona. Noticed a small bump in the tank 2 years ago (about 1:00, 6" from the fuel fill assy.) Now it is a pronounced, round raised area about an inch across (lovely on Jet Black). Another zit has recently formed at 9:00, 3" from the filler.
Pretty much filled the tank with Shell 89 octane from the same station since new.
IIRC from my plastics class, nylon is a very hygroscopic plastic. This why you can dye nylon with water based clothing dyes.

Wonder if an 07 S3 STEEL tank will fit the Tona?

Andreas - I normally use higher RON fuel, not sure what I left in it.

Problem arrises when fuel if left to stand in the tank, it actually creates misture, the plastic tank then absorbs the moisture from the inside and leaches out throught the painted side which then blisters, wosrt case tank deforms :cry:

Metal tanks sufffer with corrosion, so leasson from this is if bike to be left for winter period or more drain the fuel out

Not happy - someone should be accountable for this design flaw. Blood hippies demanding these fuels and goverment for rolling over o the minority rant rant :beatup:

Whilst I haven't had blistering, I've certainly had dimensional changes in the tank. For example, have had to elongate the holes for the front cowl and adjust the mounting holes at the front.

/media/file/82561.aspx

Some of the warping issues may arise from induced stresses by constraining the tank to the original mounting points. Having had the bike since 2000, it certainly was never hard to get the cowl or tank back on back then.
