Theres not a Tescos around me for a million miles that sells this stuff, so the test is irrelevant for me unfortuneately

How about Shell V-Power now thats been rolled out?

I wonder what the differences are between the 2 99ron fuels avalible in the UK?


Funnily enough the VPower never did it for me. BP super is the most quiet, most responsive and best fuel efficient for me.

Hi, a couple of answers to the questions.

135sport, yes, quite agree that there will always be variances bewtween fuels as they come out of the tank but the buying public buys from petrol stations as we do so the test designed to be real life. We didn't inform any of the fuel companies we were doing until we'd finished then we sent the same report to all for for comment.

emicen, sorry we didn't want to suggest no-one had done any testing but we think the length of time and process we've undertaken is more scientific than one car and a couple of runs on a dyno. Over the test the 4 cars used were run over 40 times each, the CSL over 80 times.

dkennetyvxt....LOL, exactly why we bought a Dyno Dynmaics dyno rather than a Maha so we can strap them down easier so we can measure

s5tvr, the 99 fuel from Tesco does have a cleaning package in the blend, I'm sure Greenergy would know more, there does seem to be a lot of info on their website including details on the blend

Aggy, I dont think Tesco is just rebranded Esso, we didn't test Esso Energy but I think its unlikely.

Juniorord, sorry, we weren't trying to suggest the Porsche 6 cylinders (or any others for that matter) are poor, we specialise in BMW's and obviuously have a lot of love for the straight six, yes the report does show (we think in a balanced light) that we think we know what we're doing but I don't think it detracts from the fact we did this test seriously, sorry if you don't agree.

All the fuels are the same, we only make 2 types (95 and 98) at all the refineries I've worked at. The only difference in all of them are the chemicals added to the fuel afterwards.

This might be an odd question, but would Tesco 99 result in a different exhaust note? Mine has been sounding fruity lately, since filling up with this stuff.

Any explanation for the shift in the MR2's output vs speed on th 95RON run?

Looks to me like engine speed was incorrectly calculated.

Also any reference to intake temp and Baro on the days of the runs? Were these the best of each set, the mean etc?

98 + 5% Ethanol at 114 RON or whatever it is, is I presume what gives you the 99 RON. IIRC, Shell and BP have their own refineries in the UK, all other fuel companies use the same refineries, but that's just for the raw fuel. The additive packages then added are unique to each brand.

Interesting - Tesco 99RON - and other fuels containing a lot of bio fuel (such as French super) does run the best in my Alfa V6, with better performance and a gruffer, bassier sound that is quite marked. Subjectively I'd say Ultimate or Optimax was a tad more economical though.

Like others, I'm sticking with Shell for the cleaning properties since I do plenty of quite short journeys, but when doing more miles I'm always happy with Tesco 99...


Your correct, the fuel economy reduction in high bio % fuels is because the energy content of ethanol is lower than fossil fuel.

The detergent effect though *may* be greater with BP ultimate, though.

There is a Tesco very near me that sells it, I didn't think that I'd have one so close so I'm quite pleased.

Any of you guys recon that it'll be good for a mini?

For this to be an advantage, doesn't your engine have to have an anti knock sensor in order to adjust the timing dynamicaly?

well, it has to have a knock sensor, and the ecu has to have the ability to advance the timing to take advantage of the higher knock resistance of the fuel.

Tesco is a large UK supermarket chain that sells petrol at its supermarket locations. So its not a fuel company like Esso or Shell or whatever with a network of service stations.

I don't really understand what all the HOO HA is about this fuel... I did my own research a while ago and have been using this fuel for almost six months !

Agree with Stonie......been using it myself for a while now. One other thing that is worth pointing out.....Shell Optimax (now V-something or other) is 6 or 7p/litre more than their 95 RON. Tesco 99 RON is only 4p/litre more. I'm pleased a supermarket has got one over the oil majors!
