Unbranded petrol

[neptune8]

I live in Boston, Lincs. There are only basically three petrol stations within the town itself. As my Honda CG 125 uses so little petrol, I like to use a top brand. One service station sells Esso, a top brand name.Another station sells a brand called "Harvest Fuels", which I have never seen else where.The third garage displays no brand at all, just a sign saying "Low fuel prices always". The second garage has very recently got rid of the Harvest sign, and now displays no brand name. Is this a new trend to unbranded fuels? anyone else seen this? Petrol is not cheap and I like to know what I am buying...

Forget the hype and loads will argue on here otherwise, but it all comes out the same pipe at the refinery.

It's a cg125, I really wouldn't worry about what flavour of petrol you put in it.

[stinkwheel]

Pure rumour but I heard that some of the cheaper brands can contain higher levels of ethanol.

Not a problem as such but some pre '96 bikes have componants in the fuel system that can be adversely affected (fuel lines, filters etc).

In terms of your bike and its running. A CG is in such a low state of tune, it's immaterial, any petrol for sale in the UK will be fine in it.

All brands of Petrol may be from the same refinery outlet, but I would expect different additives to be added to different brands. Back in the 1960s, my Norton 650 SS , with a high compression ratio pistons, would pink" like hell on any brand of petrol except BP five star, so not all petrols were the same then. Although the Honda CG 125 is a low state of tune engine, the compression ratio is quite high [9to1 ?] It will run quite satisfactorily on standard unleaded. It seems to start and run better on super unleaded, and gets better MPG. As regards ethanol in petrol, the pump should be labelled E5 or E10, meaning 5% or 10% ethanol in each case. As stated, ethanol can be bad news for fuel systems. It still seems odd that unbranded fuel is sold. How would you feel if your cigarette packet did not carry a brand name? Oh, wait, Plain Packaging... What next, unbranded beer?

Your living in the Teflon Mike era, if you think 9:1 is a high compression ratio these days. I guarantee the CG won't run any better in a measurable way on 98-99 RON fuel.

But your another one of these almost experts like alot of other tossers on BCF usually newbies, that come on here asking for help and advice, but at the same time almost preaching down your superior engineering wisdom and advice to everyone.

There's lots of twats doing the same thing, and many forum experts imparting their knowledge. I've definitely done the same myself though, and yet I've never seen the insides of a petrol engine, or know the first thing about how they work or how to fix one.

Hi

Not sure on what the CG125 actually requires octane wise, but would be surprised if it actually needs anything as high as 95 RON, rather than just defaulting to that as being the lowest octane commonly available fuel. The old Autodata book list it as requiring 91 RON fuel.

Higher octane fuel than necessary will give no benefit at all.

All the best

I've seen the ethanol % signs on the continent but for the life of me I can't remember seeing them on this side of the channel, however I gather fuels in UK can be up to 5% Ethanol without having to signage it.

Personally I would choose not to have ethanol added to the fuel for no other reason than it should be cheaper, but isn't. Oh, and it gives off less power when burnt.

I always thought there was only a few refinerys in the country

I know most supermarkets sell a known brand fuel but don't advertise it as such

so where do these additives get added to the fuel

do they just chuck it in the tanker as its leaving the depot

Won't make any difference to a CG125 - Get the cheapest.

The purpose of starting this thread was to start a lively discussion. I have given my opinion on petrol brands, but they are only opinions, and are worth as much or as little as anyones. I worked as a mechanic for a bus company, and have rebuilt diesel engines from the block up, so I do know a bit about engines. I still come on here to ask for advice, as I have just returned to motorcycles at the age of 71, and things change over the years. I am more than willing to accept that I am probably wrong about petrol, but am still surprised at the lack of a brand name. It would be nice if we could all respect each others opinions, even if we do not agree with them.

The IRA used to sell a lot of fuel in the 80's and 90's in eire. Especially red diesel stolen from farms with the dye removed.

It wouldn't surprise me if some of the unbranded fuel stations, especially kind of "pop up" ones are being run by criminal gangs.

Just add water to your tank, shake it about, let it settle then drain off the water/ethanol mix

I did see marginally higher fuel economy (actual numbers writ down and everything over a few tanks worth) with "premium" versus "regular" in a Seat Cordoba. But that was one car, doing one type of stop-start driving, probably with a knock sensor (anyone know of a bike that has one?), maybe 15 years ago.

I wouldn't infer anything from it. I do know that my Nazi Tractor[1] and Enfield[2] both claim to be fine running on low octane rock-juice. I honestly can't see what benefit I'd get from putting the expensive stuff in either of them.

The only thing that would give me pause is putting E10 in, and I'd prefer to avoid E-anything if possible.

It's good but want it to tell me who's adding ethanol and more importantly who is not.

I can't say I've ever seen an independent petrol station selling fuel cheap than the one owned by an oil giant 300 yards down the road.
