Tesco super unleaded test

[Donbronski]

I have recently decided to give super unleaded a try, i have been usiing tesco's 99RON as the nearest shell garage is 9 miles away. After running throw 2 tanks i checked my MPG & i have gained a whopping 40 miles per tank! whoo hooo!

Still i am quite shocked by this & will be double checking as it seems a little unbelievable.

What does your MPG work out at then? My 230TE used to return an average of about 29MPG with Shell Optimax.

At least you can enjoy the drive to Uckfield when you opt for the purer stuff though...

Interesting test, thanks.
40 miles......what's that as a percentage, 10%?

 

[Shude]

I ran Tesco 99RON for about 6 months and found it made a fractional improvement but not quite enough to cover the increased cost of the fuel.

This is probably one of the only situations when writing YMMV on a forum reply is actually appropriate!

Sounds like a very unusually high increase for an older engine that doesn't have knock sensors etc!

Did you adjust the EZL setting when switching fuels?

im thinking you were subconsciously a little lighter than usual on the right pedal when doing this test Like the old magnetic fuel savers!!

 

[Smatt]

To be worthwhile, I understood the cars' engine needed to be able to sense that you are using 99ron & make appopriate adjustments?

I've heard that they really work...the more of them you stuff under the pedal the greater the saving..

with super unleaded where should the ezl be sitting at i no it's there but i don't understand the settings

I should think the recent warm weather and longer daylight hours will be a contributory factor in the increased economy. So a 40mpg increase on a whole tank at this time of year (with the use of the better grade fuel) isn't over the top.

"Shell" fuel in South-East England is all refined by Petroplus (it was BP up to a few years ago) at their Coryton refinery.
Proper REAL Shell refined petrol is only available in the UK north of London beyond the Buncefield terminal (and even then I am not 100% sure Shell have a depot there). although the stuff you buy in Kent/Surrey.Sussex/etc does meet their higher specifications.
The Tesco and Shell petrol you will buy in your area will all come out the same refinery, differing only by the brand specific additives added at the point of tanker loading.

If you are ever in the area and you have an hour to waste, go along to "The Manorway" road which runs out of the town of Corringham in south Essex and count the number of different brands of fuel tankers which this refinery supplies. Stand there for 15 minutes and I will almost guarantee you will see at least 5 or 6 different brands...............

Tesco 99 RON in the North comes from the Conoco refinery at Immingham,

All Shell V Power Diesel is Imported and not refined in the UK as it is a Gas to Liquid Fuel and there are no GTL refineries in the UK. That is why V Power is the best of them all as its extremely low sulphur and very low in other impurities because the base product for refining is natural gas and not oil. Coupled with the excelent detergent packagaes they add makes it stand out from the rest.

Shell V Power Diesel incorporates GTL not the petrol stuff AFAIK

 

[verytalldave]

Thanks..............
However, I would expect the regular Shell petrol is still refined at Coryton.

As further info on the subject..........
I am given to understand Tesco 99 super is VERY similar to Shell V Max..............
Greenergy International Ltd - Tesco 99 Octane

You are quite correct, bit of a typo from me should have said fuel instead of petrol. V Power Diesel is all imported from Malaysia or Quatar and is indeed GTL

V Power petrol is refined to the higher RON value and then has the detergent additive packages added.

Apologies for poor earlier post but it was a late night last night

Interesting stuff, I wonder if US regulations are very different from ours?
I found this info from the US, which I suspect is not very different from the UK or anywhere else.




“My gas isn’t better for your car; it’s just more expensive.” More from Yahoo! Finance:

• What That Dollar Value Meal Really Costs the Restaurant

• Brand Names Live On After Stores Close

• Slash Your Technology Bill Without Trimming Services
Visit the Family & Home Center Oil companies spend lots of money explaining why their gas is better than the competition’s. Chevron’s gas, for example, is fortified with “Techron,” and Amoco Ultimate is supposed to save the planet along with your engine. But today more than ever, one gallon of gas is as good as the next.
True, additives help to clean your engine, but what the companies don’t tell you is that all gas has them. Since 1994 the government has required that detergents be added to all gasoline to help prevent fuel injectors from clogging. State and local regulators keep a close watch to make sure those standards are met; a 2005 study indicated that Florida inspectors checked 45,000 samples to ensure the state’s gas supply was up to snuff, and 99 percent of the time it was. “There’s little difference between brand-name gas and any other,” says AAA spokesperson Geoff Sundstrom.
What’s more, your local Chevron station may sell gas refined by Shell or Exxon Mobil. Suppliers share pipelines, so they all use the same fuel. And the difference between the most expensive brand-name gas and the lowliest gallon of no-brand fuel? Often just a quart of detergent added to an 8,000-gallon tanker truck.

I have been getting 260miles from a full tank with unleaded, full tank of tesco's super unleaded i got 300miles.

It's only about 3MPG extra, but... Every little helps

It's 15%.

That's significant. So the question is how is this saving being made because the RON figure for fuel doesn't specify that the fuel contains more energy per litre.

I think the warmer weather and longer days account for it. I've been getting an extra 3 MPG and I haven't switched fuels.

That might explain my unusually good fuel consumption figures in the last few days.
Up to last week, my best fuel figure was 43MPG. Thursday, driving home from work up the M3 and M25 to junction 4 (according to the car computer) I achieved 49.7MPG.
My best ever. Not really trying, just keeping up with the normal flow.
