Tesco must be off their trolley

[Tim Streater]

I didn't mention *what* ?

[Dave Liquorice]

True enough but the basics are correct. The distribution depots are fed from a nearby refinery by pipeline or road with the raw fuels. It's only at delivery tanker loading time are the dyes/tracers and other "things" added.

Yep, brand/type of tyre or incorrect inflation makes a bigger difference to MPG...

While we're at it let's not forget that the big oil companies can screw up their additives too, the Formula Shell debacle in the '80s proved that, screw up followed by arrogant denial followed eventually by product withdrawal and compensation.

I'm happy with the supermarket stuff but not (never) Tesco.

It *is* unleaded? :-)

I can't afford to buy five week's food all in one go! Another typical discrimination against the single person.

That it's not a 10p/litre off offer, it's a 10p/litre/voucher off offer.

[Tim Streater]

You're right. Yes, my mistake.

[fred]

Hardly discrimination, you wouldn't expect a punter to be able to drop into an ironmonger and buy a single screw at the same unit price as someone prepared to buy in bulk, would you?

[Man at B&Q]

And this is usenet and your post was lacking an important detail for it to make any sense.

Oh splllllllllthththth! I think that settles the matter.

Speaking as a married person, I was actually better off (financially) as a single person.

You can find the same information elsewhere. That simply puts it most succinctly.

It is not for the sake of spending more. It is for the sake of the engine. I view it as a false economy to save a few pennies using lower grade fuel, when fuel is hardly the major cost of owning a car, even if it is the most obvious expenditure. According to the latest AA figures each penny saved on fuel is about 0.1% of the cost per mile of running my car.

Tend to agree, s/market petrol is c^%p. I get 10% better mpg with Esso or BP. Plus the engine is probably cleaner.

With respect I find it hard to believe that fuel that is 99.95% the same[1] when exiting the refinery could show such a marked difference in fuel consumption.

[1] Based on quoted 0.05% additive introduction rates, the 99.95% remainder is the same BS/EN compliant base fuel.

Yeah and where do you store all this stuff is one of my problems.

2 for 1, buy 1 second 1/2 price, 3 for a FIVER,, 3 for the price of 4 = =20

then thre's all those elarge multi-packs of crisps... do I really have to e= at more to save space so I can buy more stuff at a lower price. No wonder one of the UKs problems is obesity.

[Martin Brown]

Really? That seems highly unlikely unless you remove your lead boot when driving with over priced Shell or BP fuel in the tank.

I can't comment on supermarket petrol but supermarket diesel is close enough that there is no measurable difference in mpg between branded expensive stuff and the supermarket (whichever is doing a fuel deal).

And I do monitor my mpg very carefully since the cost of fuel doing an annual 30k miles is non-trivial. So long as the engine lasts over 5 years I don't really care if its maximum lifetime is slightly shortened.

[dennis]

They usually come from the same refinaries.

They may or may not have different additives but most cars don't care these days.

[Owain]

Yes, for a married person it would only be 2.5 weeks' food.

Or about 4 days including hairspray, chocolate, and whatever pink fluffy and useless ornaments are on offer this week.

I can say it is less than a week's worth with 2 kids and 2 adults in the southeast.
