What do Tesco do to their fuel??

You missed a word - I've fixed it for you though.

Stay lucky.

I've surprised some folks with the result of driving behind their own car and see what happens when the driver accelerates hard.

You often can't see your own smoke - but it's still there.

I get more mpg from branded fuel so the cheapo stuff is no saving in real terms.

The points from Tesco and Morrisons don't amount to much either.

Plus you can get tesco points at Esso now!

Not really, I'm still in shorts and t-shirt.

I used to know a Canadian guy who'd be in shorts when there was snow on the ground...

The weather has got worse though, not just colder, but also more wind and rain (and this will affect mpg). Or at least where I live! That said, a 10% drop in mpg is bigger than I'd expect the weather to have caused.

Since filling up my MPG has fallen from an average of 40-42 (which I have got from every tank since owning the car) to 36.

How long have you owned the car?

18 months. So it's not the colder weather as I was still getting 40ish last winter.

Diesels wih veggie oil equals cheap motoring. Whats not to like?

A great plan until someone puts veggie in a modern CR engine, or older engine with a Lucas pump. £££

In which case I am VERY sceptical that you have got 40 to 42 mpg for EVERY tank. If that's from the car trip computer then it might be a question of this being innacurate. You'd need a very consistant driving pattern to manage such a stable mpg (which from your description of mostly 1-2 mile trips then occasional long drives you don't have), and that is before the inevitable effect of weather variations.

Here's my mpg history for comparison (click on it for details):



Lots of the variation is due to different trips (9 mile daily commute vs long distance motorway drives), but weather is a factor. For my work commute my worst average was 47 mpg in winter (snow) compared to 58 mpg plus in hot summer weather.

It is a pretty consistent driving pattern with very few alterations.

The same short journeys, which are the wife to and from work, tried to get her to walk or some other method (trying to persuade her to do her CBT and use my scooter (115+mpg ) when I'm on nights) as it is only 1 mile but no joy there .

The same shopping trips and the same weekend driving pattern (we have a very boring, predictable life )

The main difference in drives being when we go on holiday and tow, (hence the want for a diesel).

I may give it another tank if the price stays reasonably close and see if it is a case of the engine "getting used" to the different fuel.

Do you get sugnificantly higher mpg for your longer trips? If not, your car has a problem, possibly a faulty temperature sensor.

My 47 mpg vs 58 mpg comparison is foe fill ups for 100% trips to work and back, with variation due to traffic and weather conditions.
