I don't use Momentum 99 because it contains 5 % ethanol (maximum allowed currently) and an additional 3 % methanol; both help improve combustion while controlling knock, which is why it can deliver 99 RON, but the reason ethanol content is limited to 5 % is early engines (like ours) were not designed for high ethanol content fuel and it can damage the seals, adding 3 % methanol makes the matters even worse.

Fezzasus, I thought the problem with seals etc was only on pre 1990's cars? I have a Triumph stag and I have been advised to use an additive in the fuel to counteract the effects. I have a bit of 'JG' scepticism though about it.

Completely different issue, that's the use of lead as an anti knock agent. The valve seats are too weak to cope with non-treated fuel.

BTW; ethanol content is still an issue with cars made today. VW Brazil had a massive issue that lead them to replace whole engines a couple of years ago, Daimler are currently designing a test to look at biofuel induced corrosion, PSA have biofuel oxidation tests - all of these tests have come in in the last couple of years. the engine manufacturers still arn't on top of it.

I wouldn't recommend it either, but that's based on certain technical reasons rather than leaving it open to speculation.

I'm a bit bored of the wink wink, taps nose, posts fezza.

I'd prefer an open honest post or nothing at all.

The engine oils my company has designed and produced are used in one third of the cars on the road - I simply can't give all the information you want away, however I certainly don't want to create the opinion that i'm deliberately making things sound secretive. If you need clarity on anything i've said feel free to ask - I will try to expand on it as much as I can.

No the Valve seats have been changed along with the valves, it's more about corrosion of copper, tin and rubber hoses/seals.

This is the stuff that has been recommended.

Theres loads of stuff written about E10 on the classic car sites

My concern is as follows: Some years ago TMS recommends Tesco fuel - with some fairly convincing "expert" reasons to back it up. Now they do a 180 degree turn and recommend against using it. I see two possible scenarios: It's a case of "toys out of the pram" because of some issues with Tesco. That seems a bit petty, does not invalidate the original recommendation, and is rather condescending to those customers that followed the recommendation. Or, the fuel has significantly changed since the original recommendation, which is therefore now invalid for good technical reasons. In which case surely the customers deserve a reasoned argument for the about turn? Either way TMS don't come out well. I used to rise above the Thorney-haters, and always took my VX to Milton Keynes. But I'm not sure I'd go back now. Baz.

[Mike (Cliffie)]

But you don't have a VX now Baz so I doubt your loss of business will be a massive blow I believe the reasons are fuel related and not toys out of pram over sponsorship which ended a long time ago.

[slindborg]

If the fuel is 'that' bad that he would risk the business image then surely it shouldn't be sold anymore and trading standards should be involved etc blah blah blah.......

[Mike (Cliffie)]

Dunno Stu but I will hold judgement until I know more of the facts.

So does that mean that meth injection kits aren't very good for the engine?

[fezzasus]

Yeah, but if you're using methanol injection then engine durability won't be high on your list

I doubt there are any facts to find out.

Bugger. I just filled up with that Tesco stuff because my Shell garage was packed. I'm sure the odd tank here and there won't hurt too much.

It was/is/still is about warranty claims isn't it? TMS tuning centres cars go bang...somebody is to blame. Vauxhall don't want to know, as they 'trust' TMS to tune them (after all TMS do their tuning in their garages) TMS don't want to pay for all the broken cars, so who else is in the equation*? *Somebody with an open cheque book for Lawyers in such circumstances. And you don't sponsor somebody who is suing you do you? All of the above is IMO btw

[FLD]

Is it worth analysing some fuel? I use tesco's simply because its closest.

[VX-GT]

Speak English Doc

If somebody say's its good (but not qualified to make that statement)
then only to say its not good

Then both statements and the author can not to be held with any regard

It may well be that tesco have asked for this dis-association from a discredited organisation

Jules, thinking about it I think you're spot on.
