Tesco Momentum99

Nednats

I have just discovered Tesco Momentum99
Its advertised as:

• Increased Power
• Improved fuel Ecommony
• potential saving on fuel costs

But it is 5p a litre more

You can review result of tests on their website.
http://www.tesco.com/Momentum99/productBenefits.asp

They can thow at all the data they want at us but the real test is has anyone tried it?

What are your opinions and experiences of using this fuel?

Do you save money?
Fuel is expensive is it but if your spend 5p more a litre will you actual save money? Will it last you longer?

It's a 60 mile round trip so probably not worth it for me.

If the mpg percentage increase is greater than the cost percentage increase then yes you will save.

Note that they were comparing Momentum 99 with standard Tesco fuel. I wonder what a comparison with 95RON fuel from a non-supermarket would be like.

Intresting thought

I have read the test report pdf. If they have tested the way they state and numbers haven't been fiddled with then there is clearly some advantage to the Momentum 99 fuel, although I would not say the MPG increase figures could be fully relied upon given the method of noting mileage when the fuel light comes on and being only over 3 tank fulls. I would have liked to see some more data, perhaps even raw data.

Taking their figures for the Hyundai i10 1 litre gives the following assuming a fill amount of 45 litres

45 litres @ 115.9p/l = £52.16 a tank
40.55mpg gives a range of 401.39 miles
Per mile cost = 12.99 pence

45 litres momentum @ 120.9p/l = £54.41 a tank
47.55mpg gives a range of 470.68 miles
Per mile cost = 11.56 pence

A saving of 1.43 pence per mile. Hope I've done my maths right (and even more-so that the people doing the testing have done theirs right).

And for the vehicle tested with least MPG benefit the Honda CRV 2l

45 litres @ 115.9p/l = £52.16 a tank
31.12mpg gives a range of 308.04 miles
Per mile cost = 16.93 pence

45 litres momentum @ 120.9p/l = £54.41 a tank
33.59mpg gives a range of 332.49 miles
Per mile cost = 16.36 pence

0.57 pence per mile saving.

when i had my subaru it ran much better on the tesco99 as it was called then,more responsive and better mpg compared to super from bp etc.
the only comparable was shell vpower but that was more expensive than tesco.
however if you drive a standard car then i would not bother,it is best suited to performance cars.

Is this just re-braning of Tesco99 or is it a different fuel?
Is this just super unleaded?

Yep, it's just a rebranding of their Super Unleaded with a un-natty 80's style font.

Bear in mind that apart from a few (very few) cars that recommend/demand high octane fuel, cars are mass marketed and their clever little ecus and sensors allow them to run on very dubious fuel (say Bulgaria) and up to your premium oil giant forecourt here. There is very little difference between the fuels we can buy in the UK and most improvements in mpg or HP are not consistently proveable. Stick to buying the cheapest fuel from somewhere on your normal route.

I have to Agree in some part with colino, but also add an occasional tank of super / premium isnt going to break the bank and is probably benificial.

Unless you have a knock sensor, it's unlikely you'll notice a performance gain.

Fuel octane is not a measurement of "power" of the fuel, it's infact how difficult the fuel is to burn. The higher the number, the more difficult the fuel is to ignite. So 95 RON fuel (standard unleaded) burns more easily than 99RON fuel.

I could explain it, but this post would run into pages and probably wouldn't be understood by quite a few users, as you need to have a pretty good knowledge of cars to comprehend why a harder to burn fuel increases performance, but most cars will not take advantage of this.

Unless you have a knock sensor, or you can retime your engine manually, (few cars made since about 1990) then it's pointless.
