Cheapest Petrol & Diesel Discussion Area

Hi,

I've not tried Tesco Momentum 99 fuel. I've used both Tesco Petrol (95) in my present vehicle and Tesco Diesel in my previous. And each car wasn't happy with either! Or with any supermarket fuel come to think of it. I thought initially it was because the old diesel Citroen with 175,000 miles on the clock was getting tired and cantankerous in her old age, but on filling up with Shell Diesel she had a new lease of life - and an increase of 5 mpg:eek:. I've found the same with the present car, a petrol Mini Cooper with 30,000 miles - same thing, car not happy with Tesco, like a rocket with Shell 95 and an extra 4 mpg. Will try the new Momentum 99 when next required. At the time there was a penny or two difference between the two suppliers, Tesco being the cheaper .

The point I'm making is... Although Tesco can be the cheapest, it's calorific value is not that great and can be cost-ineffective!

TBH I have never noticed any difference in performance or mpg with whichever petrol I fill with, whether it is Shell, or supermarket brand.

I Heard there is going to be another price increase at the weekend beter buy an electric car anyway

If I use shell unleadded will my bike go further like it says on the advert and if I use Tescos momentum will my bike go further

As for Tescos normal unleadded it dose not have all the extra chemicals than shells or Texaco it's less quality thats why it's cheaper thats whu some forum members cars don't like using it

In my area (NW London) yesterday, the following prices were observed.

Tesco 128.9

Sainsbury's 126.9

Shell 124.9 (the price changed from last week's pre-fuel escalator, and VAT on Wednesday afternoon).

I don't reckon you go any further with one particular brand. It is the way you drive and the type of journey that counts.

For LPG autogas I dont know about now but johnston oils used to be 10p/ltr cheaper than retail forecourts, what you do is sign up for an account, they give you a fuelcard, you pay at the pump and your spend comes out direct debit every friday. They do diesel cheaper too but only for business customers, but they allow private individualsto get an autogas account.

While switching off your aircon will take load off the engine and improve consumption do not leave it switched off for prolonged periods. The gas flow round the system carries lubricants which keep the valves and joints in the system in good condition and stops them drying out. A good practice would be to switch the aircon on for a few minutes every couple of weeks or you could be in for expensive repairs to the aircon which will far outstrip any fuel saving.

By your suggestion would it not be an idea to keep it on permanently? I always thought that the aircon used more fuel?

I have used Tesco fuel and in my Honda Jazz I get around 41mpg - If I use fuel from BP I get around 46mpg.

Is this saving me money or is it a false economy?:T

I-LOV-MONEY

Well from what you say you are obviously getting better value for money from BP.

However - do you have to travel further for the BP ? Are you doing exactly the same journeys using the different fuels? I know my mpg changes from fill to fill, doing the same or similar journeys. However, I have never noted which petrol I am using at the time - I will make a note for the future !

I'm surprised at the advice given in the news letter. Urban myths abound.
I read a report of tests done on a test track (blowed if I can find it again).
Tyre pressure makes almost no difference to fuel economy unless they are nearly flat.
The weight of your car only makes a difference when you are accelerating or going up hill.
Why do we need air con in the UK anyway?
If you find a cheap fuel station, fill up. It might not be cheap tomorrow. Weight? See above.
Acceleration? Agreed. Make it steady.
Highest gear possible? No, that does not stop the engine labouring. Select the correct gear to make life easy for it. Thats why we have gears.
The biggest killers of fuel economy are wind resistance, hard acceleration and hard braking. See this article: www dot aerocivic dot com.
Speed: driving 100 miles at 70 takes 1hour 25.8 minutes whilst 100 miles at 55 takes 1hour 49.2 minutes, a difference of 23.4 minutes or 16.4% longer. Considering that fuel usage at 70 can be 33% greater than 55, consider, is it worth it?

The Article says fill with cool fuel in the evening. Surely it will be cooler in the morning after storage underground during the night?

Not sure about your statement that tyre pressures have little affect on fuel consumption.

On a safety tack - wear and grip will be affected by tyre pressure, eg low pressure tends to close the tread pattern so less grip on wet or snowy roads, and high pressure puts less tread on the road so less grip. Certainly my motorbike's handling deteriorates as pressures drop below the recommended levels.

When Cost Co tyre shops supply 2 new tyres they always put the new tyres at the back rather than the front. They say that .....since the vehicle weight (centre of gravity) naturally moves forward under braking this helps front tyres to grip. The rear tyres are lightly loaded under heavy braking, therefore, we need the the better gripping tyres at the back to keep the car in line. I found this a bit counterintuitive but have come round to their logic now.
