Tesco momentum Vs V Power

Recommended Posts

Nice new engine for free, no bad thing, a massive inconvenience granted, the modified bit is irrelevant, it was all cars that suffered.

Good luck finding a new DE. Picking up contaminated fuel obviously out of ones control, I'd personally would rather it not happen and could do without the hassle.

 

A forecourt could say go away and prove the fuel sourced from this station caused the engine fault. Prove that those decats and remap *declared to insurance, plugs that have never been changed weren't the cause of the engine letting go. Does the engine have full vat registered garage service history, helping to indicate it's overall health. Stands a chance a fair few cars on the forum would fail on some of those points alone. Yes we know those wouldn't directly cause an engine to let go, possibly proving it is another thing. Then if the forecourt insist you pay for a fuel sample to be sent off. Independent engineers report on the cause of the engine failure. Yes in long run you'd get an engine rebuild. By a specialist? Maybe, maybe not. Overheating issues afterwards as the cooling system can be a pain to do. Misfire at high rpm as dmf been put on a bolt pattern out? Again I'd rather not have the hassle but everyone's different right.

I was making a point in referral to another post re contamination and it wouldnt stop me using a tesco because once in a blue moon there was a problem, any tanks, shell or tescos could get contaminated, you would pretty much be covered either way as it wont just be a single car with issues (as was the case here) and I seriously doubt either would want the bad press that they are causing a fuss for repair work. If folk regularly had problems with Tesco fuel that would be entirely different, but they dont ;)

I would wager that stick some fuel into a car and get someone to drive it and guess which one it was from Shell, Momentum or BP and it would be literally guesswork it wouldn't be a case of definitively picking Shell correctly each time. All fuel comes from the same refineries, its the same base stuff, if the additives Tesco were putting in were so bad it would be on Watchdog by now. I recently drove my car across Europe, using all manner of different brands I had never heard of but always putting in 99 and never noticed any discernible difference to any of them or against Shell.

The damage won’t be noticeable in a few tankfuls though, it’s years down the line. The same as running 95 ron won’t be noticeable in a zed until damage is seen in the future 

 

And don’t believe everything you see on watchdog. My cousin was interviewed by watchdog when he was working for a company who were featured on the show. He was manipulated into saying what they want us to see, not the truth. It’s an entertainment show just like anything else on tv

Tesco has been selling fuel for years, probably to motorists who have done hundreds of thousands of miles, is there any supporting evidence that those motorists cars have suffered as a direct result?

Exactly this, my parents have lived in their house for nearly 30 years and Tesco is the closest petrol station. My dad has owned a number of cars, some for 5-10 years, always used it, his cars are fine (and being a mechanic of 50+ years experience would notice any fueling issues). There is no news/evidence out there showing that extensive use of supermarket fuels cause long term issues, if there were, Shell and BP would be using it extensively to dismiss supermarket competitors in their marketing.

I ran my 350 for 5 1/2 years on mainly Tesco Momentum and never had any problems. Filled up with V-power and the only difference i could notice was the price.

 

I would only use just one type of fuel if i had a highly tuned boosted engine that was mapped to it. All fuel sold in the UK meets the standards set so use whatever you like; just as long as its higher octane.

I don’t have the evidence I was told by 3 different mechanics to avoid them

 

When I had my zed I ran it for around 2 years on standard fuel before finding out about the need for premium. Never had any issues. Would I run my 350gt on standard? Nope, course not. But how many zeds out there have been run on standard and haven’t had issues

 

They weren’t saying every car run on supermarket fuels will have issues but there’s a much higher chance due to the differences

I think cars are more likely to fail due to other things - lack of oil, maintenance, stress caused by poor setup, tyres, etc. than having a slightly different additive mix in the fuel.

I view it as eating supermarket crisps over posh crisps: Sure, one may taste better depending on how you feel that day, but neither is going to keep you alive for longer over a billion other variables.

 

 

Mmmmm crisps...

So do you feel like Asda’s own brand crisps or would you prefer walkers for a few pence more?

I prefer the walkers ones, but in terms of health benefits neither are going to make any noticeable difference to my life expectancy. The benefits I get are purely aesthetic i.e. the familiar taste. Both have the same fat content and carb content. If I was hungry and wanted something to eat both equally satisfy my requirements.

True. But fuel is vital to a car and lower grade fuel can affect how a car runs. So take your crisp analogy and shove it where the sun don’t shine Dan :lol:

 

Or you could compare it to something like dishwasher tablets, or washing powder. A cheap brand will pass all requirements and do the job fine. Or you could get something of a known brand

Ive said it before, if someone can show me how the car knows or measures what fuel is in it and then adjust its ignition timing accordingly Ill believe theres a difference. Otherwise Ill stick with running 99 in my BMW to avoid det as thats what its mapped on and not worry about the others :)

^^^ This! Least of all driving, how do we know those cars running tescos werent driven like they were stolen day in day out, run low on fuel sucking sh*t up from the bottom of the tank, had fuel filters/spark plugs/air filters changed. I am afraid its just one of those good old internet myths being perpetuated without anything being substantiated.

I stick with V-power since I bought my Z.

I don't like all of the additives they put into Momentum to bring the octane rating up, and I know an old friend ditched them when they were sponsoring his race cars.

That was enough for me to avoid it.

So if Tesco did one brand car oil, met all the requirements for your car, next to it was a branded oil for a pound more, which would you go for?

 

If a budget tyre brand made a tyre that was all the same grades as MPS4S, in the real world you dont know how well they actually perform, would you try them or stick with tried and tested? (That ones for Dan)

 

Same question with brake pads and other consumables on a car

The only oil I don’t use is Magnatec, as I’ve seen first hand how thin it goes when warm. Nowadays I’ll use whatever is on offer at ECP in my cars, and change it every six months. 

 

If there was a budget tyre that performed identical to an MPS4, then why wouldn’t I buy it? I’d buy any tyre that was excellent and suited the car in question, which is why the Scoob runs RE070 and the Omega some cheaply nonsense tyres. 

 

Brake pads, tyres, seats etc: these all have physical properties I can tell the difference in quite easily when driving. I’m sure I could tell a car on stale fuel over fresh fuel, but between Tesco and Shell? Nope, I’ve never ever been able to tell and as said above, I doubt 99% of people ever would be able to on a blind test.

Problem with supermarket fuels is the winter and summer additives. Supermarkets buy fuel when its cheap, store and sell all year round. Selling summer fuel in the winter brings its own issues, this is what we've found in past years in the leasing industry for regular octane fuel. Whether this buying model is carried over to the 99ron is doubtful, as its a different supplier completely to Tesco's regular 95ron.

Until I see something comprehensive that shows either; in long term tests momentum is statistically more likely to damage engines and that momentum gives significantly worse performance results I am happy putting either in. If a lesser brand oil in tests showed it was statistically as good as a better brand oil at a lower price, yes I would buy the lesser brand oil, that makes complete sense. The point is not is one better than the other, its that there is no proof showing that the only difference being price (and the belief that more means better) and marketing.
