Scubaregs Posted November 26, 2019 Report Share Posted November 26, 2019 A quick google says tesco momentum contains 5% ethanol and Shell V power up to 5%. Link to comment Share on other sites More sharing options...
Patt Posted November 26, 2019 Report Share Posted November 26, 2019 Momentum is now 6p more than standard - it used to be 5p. I buy Momentum down south as the local price difference is considerable, I buy Vpower t'up Norvf as it is usually all I can find. And at least 2p/ltr cheaper too.

½cwt Posted November 26, 2019 Report Share Posted November 26, 2019 I believe all fuels now have to have a minimum bio or ethanol content, 5% for petrol and 7% for diesel. You'll see E7 or E5 on the pump or nozzle. This is eco rather than performance related though. This might make older articles a bit misleading now.

Apparently Esso 97 is still ethanol free, despite the pumps being labelled e5. Not where I live though..... Link to comment Share on other sites More sharing options...

Esso suprer is ethanol free unless you are in devon / cornwall and parts of scotland apparently. 4 hours ago, Scubaregs said: A quick google says tesco momentum contains 5% ethanol and Shell V power up to 5%. didn't realise Tesco was low - good to know - although there's not one anywhere near me - Morrisons or Sainsburys are the nearest.

½cwt Posted November 26, 2019 Report Share Posted November 26, 2019 Current situation is outlined below form the AA https://www.theaa.com/driving-advice/fuels-environment/biofuels Looks as though fuel manufacturers can add up to 5% ethanol and not even state it but is 5% more have to state it and from Sunday (1 December) label the pumps E5 or B7 if they sell 450,000 litres or more. They are 'greener' if they use the renewable ethanol under the RTFO Renewable Transport Fuel Obligation structure, a bit like the various electricity suppliers 'buying' power from wind, solar etc under the Feed In Tariff which superseded the REGO or Renewable Energy Generation Obligation. The article also refers to E10 in France which I guess will also come over here. Remember the 4 star leaded to unleaded switch over? Going to happen again. I guess a 986 or 987 Boxster (981 and 718 may be???) is not E10 compatible. Link to comment Share on other sites More sharing options...

I don't think anyone has ever been proved wrong or right on this, and for most of us road usage - we would likely never notice the ecu dealing with lower RON, you might on a track day etc. But we all have our "religions" - low ethanol and a fuel that is 1) at the end of my road and 2) a "good" one is one of mine Link to comment Share on other sites More sharing options...
Richard Hamilton Posted November 26, 2019 Report Share Posted November 26, 2019 I use an additive called Ethomix in my 911, which eliminates the side effects of ethanol. There are quite a few such products available now. Link to comment Share on other sites More sharing options...

martinjohn308 Posted November 27, 2019 Report Share Posted November 27, 2019 I’ve been using V power Shell ever since I bought the car in 2010 works for me as I don’t use the car every day. Regards, Martin Link to comment Share on other sites More sharing options...
Mattman42 Posted December 2, 2019 Report Share Posted December 2, 2019 Stopped at Esso the other day - regular unleaded was 123.9 but the Super stuff was 142.9 - 19p a litre difference? that's the biggest i've seen for a while - and its not even at a motorway services Link to comment Share on other sites More sharing options...

My local Shell 125.9 for 95, £138.9 for V Power. 13p/litre seems to be their price difference at other sites too which I can live with. Are Esso taking the ….?

Paul P Posted December 5, 2019 Report Share Posted December 5, 2019 PCGB have an esso fuel card. Gives a bit of discount on fuel. its “pushed” as 1p / litre on regular and 2p / litre on super hr like DFS they always seem to have a “sale” on. Where it’s 2p and 5p cheaper discount. The card is free. And it’s not tied to any refg number so the daily driver benefits from it as well. Works well for me since esso is end of the road so is my goto station. Takes some of the sting out. Link to comment Share on other sites More sharing options...

naim22 Posted December 28, 2019 Report Share Posted December 28, 2019 I definitely always run with high octane fuel but that's purely based on my own experience with calibration and control of more modern engines/fuel systems. The benefits of doing so are definitely tangible, but aren't always reflected in higher fuel efficiency or power output, so it can be hard to spot as a driver. It can only really be seen by digging into the vehicle log data Link to comment Share on other sites More sharing options...
mortzz Posted December 28, 2019 Author Report Share Posted December 28, 2019 On 11/21/2019 at 10:28 PM, Shazbot said: The ECU via the knock sensor will retard the ignition on 95 compared to 98/99. Therefore you will get more* power and better drive with premium. *Unlikely you'll notice under normal driving conditions though. I run Tesco Momentum as its only a few pence more a litre than regular and the car definitely runs better on it. Spot on Fella, I realised the ECU would retard the engine but its whether you can tell, Link to comment Share on other sites More sharing options...
usman10316 Posted December 29, 2019 Report Share Posted December 29, 2019 I made the decision to put in morissons in my boxster as I had the 10p off per litre voucher. Can confirm car is not dead and still running fine! Link to comment Share on other sites More sharing options...
Senna Posted January 1, 2020 Report Share Posted January 1, 2020 I use Tesco Momentum. It seems to work ok, and it’s only a few pence more. On occasions that I can’t get hold of 99, 95 seems fine Link to comment Share on other sites More sharing options...
