Tesco don't always buy from the same oil company

Momentum is only made by Greenergy in the UK for Tesco

I decided to use my 3 vouchers last night and filled up with some Momentum. Time will tell but feels OK today!

forget all of the above this is what you want, race fuel, when i was at croft watching the btcc , we had a walk round the pits on saturday and watched the honda garage fuel up with this stuff!

I recently switched to using Tesco Momentum 99 in our Yeti 1.2 DSG, and have gone from averaging 43mpg with Tesco 95 to averaging 48mpg with Momentum 99. For an extra 5p per litre, it saves money and uses less fuel. On my 6000 miles per year, I'll save around £60 (1p per mile).

Just need to watch out for Tesco gradually pushing the price differential up.....

Its an absolute deal in tescos batley, west yorks, 136p a litre for momentum (before any 5p vouchers off), local to me the shell v power stuff is about 10 p more than this in price and v power is 9-10p dearer than shell regular unleaded.

£5 saving a tank before any vouchers is definately worth having at prices these days.

What's BP like? I've got a couple of Daily Mail "£5 off any fill up" vouchers.

Running on Tesco Momentum in my vRS have been for a good while now and it does run smoother, got 43.1MPG on a run up north last night, helped I suppose by the immense length of the roadworks around Luton on the M1 and being sat at 50MPH.

I have been using almost exclusively Tesco 99 for the last 10k mile or so, just tried a tank of 95 as there was no 99 available and I swear it's quicker! I have tried in the past Shell V Power, and couldn't really tell any difference to be honest, but I think I have a power issue with my car anway - an 06 VRS

Does anyone actually believe this? And if it is exagerated how are they getting away with such wild claims?

Audi TT 2.0 (same engine as vrs petrol)17% better mpg,You've gotta be kidding.....

Impossible! A lower octane fuel cannot produce less power in a vRS, and it probably wouldn't show up in just one tank.

I think it is probably just coincidence or like you say you have an intermittent engine problem.

Not sure on the mpg front but as a die hard vpower fan I thought i would try momentum this week. The car feels to pull better than it ever has, really impressed and I'll be buying it again.

An independent report, well produced, well documented.....that's how they get away with it.

Don't forget they aren't comparing a like for like product. Momentum 99 is 4 octane points higher than their standard petrol, so is always going to produce more power which roughly translates into better economy. Higher octane fuels also produce different results on different engines; with performance cars generally reaping the biggest rewards.

They have given empirical evidence, and as such some errors are always possible, but I'm sure if it was majorly flawed the big oil companies would challenge their findings.

Don't like, don't buy.

I've used this from day 1 of purchasing my vRS, and always found it to be nothing but excellent.

Tried many fuels when I had my mk 1 vRS, and found Shell and Tesco both gave good results, however Tesco is always at least 5p / litre cheaper. No Brainer.

Because you have read it how they hoped you would - you have assumed that the 95 RON is the benchmark and 99 RON is 17% better.

It could equally be interpreted that the 99 RON is the benchmark and the 95 RON is 17% (or whatever) worse. In other words, it could be that Tesco 95 RON is total and utter carp and 99 RON is run-of-the-mill.

This very limited test only compares 2 batches of 2 specific fuels and the results should not be extrapolated to all 95 vs 99 RON comparisons nor to these Tesco fuels in general. In their own pre-amble they confirm that fuel varies from batch to batch but this is the one variable they have failed to account for in their test plan so they could have tested a particularly bad batch of 95 and a particularly good batch of 99. Bearing in mind the specific nature of what they were trying to prove, dare I suggect that some (un)conscious batch selection may have occurred. To allow the claim that 99 RON Tesco gives better mpg they should have tested multiple batches of 99RON Tesco against a range of leading 95 RON fuels.

I will be filling up with Momentum tonight,will let you know how I get on.(usually use V-power)

We've always used Tesco 99 and then Momentum in our Leon FR and it runs fine with no hesitation or pulling issues. The only problems have been when they have not been available and we've had to use 95 or even worse Sainsbury's 97 then it did cough and splutter! Don't forget when changing fuels it takes a while for the ECU to adapt to the different characteristics and probably if we had persisted with the change of fuel the engine would eventually run fine.But as said its fine on Momentum so no need to change.

I think it should! In theory, lower octane = lower power therefore a lower octane fuel should produce lower power in a vrs!

Apparently there is nothing wrong with my motor, so it's probably in my head. The key thing is, I can't really tell much difference between the two, though the economy suffers by 2-3 mpg with 95 RON. As for waiting for the ECU to learn, that's not the case. The ECU will advance the timing instantly until the knock sensor constrains or retards it. This feedback loop is running constantly at several hundred times per second, so will instantly adjust to the fuel type. I suspect that firstly the 95 RON is conatmined with a couple of gallons of residual 99 (which is probably what people observe with the need to run a couple of tanks to see the full effect of the fuel change), plus I am not convinced that all Tesco petrol is the same (despite the badge on it).

I have come to the conclusion that the power delivery is so linear, that you just don't get the feeling of a snap of the neck type of on/off boost of a high torque diesel. Maybe I just need another 50lb/ft or so of torque...

I've been reading pooch's post over and over and it makes no sense, I think he meant to say "...more power...".

If you fancy an extra 70-80lbft of torque over standard, help yourself to a stage 1 remap!

I'm fairly sure that it says somewhere in the doccumentatin that came with my car that the power output is given as 147 Kw when using 99RON petrol, if using 95RON the output will be slightly less.

haha... you're right! thats what you get for typing on a damn phone.

meant to say higher octane cant produce less power.

you get my drift.

I always use super unless there is nothing else or it's a really stupid price. I only really notice a difference between super and 95 if I have to use supermarket 95. I can only describe the effect as making the car feel heavier.

This is much less pronounced with Shell 95 petrols and I'd probably happily use that if I had access to it nearby.

V power for me,

Tesco petrol is always a last resort

I just use what's available. I use both Supermarket or Branded.

I filled up at a Total garage the other day with £65 worth of Super unleaded and I found it stuttered a bit, I've just filled it up again with JS Super unleaded and the stuttering has stopped. :wonder:

Next time I'll fill it up but give it a shot of either Redex or Millers Ecomax to give it a bit of a clean out.

On my second tank of Tesco 99 and easily gettin 400 miles to a tank (£70)

400 miles?!! I couldn't get that if I drove with an egg strapped to the sole of my right foot.....

I have been booting it a bit the last few days, on the basis that a colleague with a BM 645 coupe tells me that there is about 20 minutes "learning time" on the ecu so as to avoid an on/off engine map response, which makes sense. Anyway, a few forays past 6k and it certainly wasn't hanging about when powering out of RABs on the way to work this morning.
