Esso's new fuel

[Jasonn]

I've seen that Esso have now released a 99 RON fuel to compete with v-power and momentum - it's supposed to be 'ethanol free' in some locations.

Has anybody tried it yet? I've just filled up with sainsbury's 97 RON as I ran way too low and couldn't get to my local Shell (spoiler alert - its crap)

At 27p per litre more than their standard unleaded fuel at my local Esso station, it needs to be good

[Mr Tidy]

Ouch - that sort of premium is why I don't use V-Power very often!

Luckily I'm only a mile from a Tesco and their Momentum is only a few pence dearer than regular unleaded so my car usually drinks that.

27p a litre?

Are you needing that in gallons old-timer

I am a little wary about using Tesco fuel after the time that they had that contaminated batch (I had a colleague who's car ended up requiring repairs as a result).

I know that momentum is 99 RON, but does anyone know if it has detergents in it? I noticed that after a few tanks of shell v-power the car seems much more responsive (a one off fill doesn't do anything).

Esso's 97 RON seems OK (definitely better than sainsbury's 97 RON).

Worst I've ever used was Morrison's 95 RON (BP's 95 RON was way better).

Anybody else noticed the same? I thought that the RON is supposed to be consistent across the brands

Tesco momentum does have detergents along with all other super unleaded fuels to my knowledge, different fuels behave in different ways according to how the RON is obtained - if there’s a high ethanol content it’s not as good for economy for example.

BMW and I recommend 95 RON.

I have used Tesco fuel for my cars for at least 6 years and have never had any problems

Me too for 15 yrs + as it’s the only option and I’ve never had any issues either. They don’t sell anything other than standard 95 RON unleaded and diesel. Nearest premium fuel is probably 70 miles, nearest Shell 85 miles. (Each way)

No benefits to be gained whatsoever with anything higher than 95RON, especially if you don’t have a high compression engine.

Indeed, do the E89 engines improve their performance on higher Octane petrol? I have know idea just asking..

Certainly the S54 needs it in the E85 M's but what other Z4 engines are designed specifically to run better on the higher Octane fuels?

[montymoore]

If the fuel has a higher octane you WILL get more MPG the question is really how much and is it worth it. When I had a Cayenne S with 4.5l V8 higher octane fuel 99Ron gave me 5% better MPG but cost more than 5% more but i still bought it as I liked the idea of higher octane and some cleaning agents. But TBH probably not really worth it. I do put premium petrol in my z4 now but that is me just being "nice" to the car!!

Forced induction engines will benefit from super unleaded, especially remapped cars that sail closer to the edge.
So n20 & n54 engined e89’s, the n52 versions won’t really gain.

Absolutely no idea what you're talking about 'old-timer'? Oddball.
