Lads, one of the M Sport badges stuck on the wing has come loose on my F10, any idea what adhesive is best to use to stick it back on but at the same time won't damage the paintwork or metal?

If you clean the surface with a degreaser and use some tec7 carefully it should survive a nuclear blast

how long will be have the expensive fuel? paid 133 for diesel today and one forty something petrol the other day

Its a Volkswagen 411 4 door.

Definitely not a '61 reg. '69 would be right.

My Golf is in the garage for its test. Got a poverty spec VW Fox as courtesy car.

Manual windows, no airco and a tape deck. Love it.

Front end reminds me of Peugeot 504, but pretty sure they weren't around then. Some other Peugeot maybe?

Reg is 1969 I think.

Wonder how long more we'll have this for !

145.9 for petrol in Wilkinstown on Saturday, Texaco. No price/interest for the diesel but I'd guess it's one-thirty-something

The local Tesco in Wicklow has diesel at 126.9 .... Not quite sure how though

My car is officially 1 year old tomorrow and I did 24k km in it so far. Damn time flies!!!
So far, touch wood, had no issues with it. Still loving it.

Got 40mpg driving up and down to the aviva yesterday in the 2.4 petrol Audi on trip computer and ive been getting 60mpg in the superb checking brim to brim

That's very good for the petrol. Is the superb the 1.6 litre or 2.0?

Re air temps/economy - humidity is important as well, esp in petrol combustion.

As for air density, which rises with lower temps/humidty ,it's important in different ways - in your engine the denser the better but for aerodynamic efficiency it's bad.

Air resistance is a factor too obviously. In warmer weather, with less air molecules compared to cold weather, air has less resistance which would help a little with fuel economy. But the big one, especially for a diesel, is the engine warming up quicker. Im sure its a combination of many things but there is definitely an improvement.

I'd say your calcs are out a tad.

Even at 131mph? Impressive....

average speed including drives ones or twice a week above 120mph and rest of the week just normal with quite fast acceleration gives me 52-56mpg by the end of the week

Spotted this on Bargain Alerts. I have this exact socket set for years and it’s excellent think I paid €30 for mine at €18 it is a steal I have used mine a good bit and it stands up well to any abuse ratchet feels very sturdy and well built. Plus it is compact and handy to have in the boot I have one of the bigger 170 piece sets but that’s too big to haul around all the time. Might actually get one as part of a present for my Dads birthday.

I want it even though I have all those bits in the more advanced kit! Even if you don't have a use for it right now, it's still a great buy. Keep the receipt and you have a life time warranty too. Not that I've ever successfully broken any of the bits in mine over the years.

I have noticed a small improvement in my MPG with the warm weather. But I think with a petrol you don't see as substantial a difference as even in the cold they heat up reasonably quick whereas diesels take an eternity to heat up in cold weather. On a long trip last week got 49.4mpg tank average calculated with the brim method which I thought was fair going as it is a decent enough size car and petrol. Don't take the diesel version in the same car would do massively more.

A friend has a similar A4 to yours..... he never sees under 45mpg from a tank. He's not overly light footed but does lots of long journeys.

Some cars have electric water pumps, a lot of newer BMW engines do for sure.

In theory once a car is warmed up it should use less fuel in colder air because it is denser and has more molecules.

As points against that, engines will warm up faster (especially big engines and/or diesels) in the summer, which can save a lot of fuel, and perhaps there are other benefits like tyres, road conditions etc, but the cooling system will be under more pressure to keep the engine at the right temperature and loads on the engine will be higher due windows being open or else air conditioning being on (although I tend to use air conditioning more in the winter because of its effectiveness at keeping the windows condensation free, in the summer I like the windows down so I can hear the engine more:D).

Just my 2 cents on the better mpg on a warmer day discussion.

I come from the power generation industry, specifically gas turbines (which are just huge jet engines), and they perform better in colder temperatures for the simple reason that cold air is more dense/compact than warm (expanded) air, this means that the turbine/engine can take in more air if it’s colder as opposed to warmer air.

I don’t know the exact figures, but I know that there are more air molecules in 1 cubic metre of air at 10 degrees than there are in 1 cubic metre of air at 20 degrees, which results in better/more efficient combustion when the air mixes with gas or diesel (which gas turbines also run on).

I would have assumed the same principle applies to car engines, however the higher ambient temperature could result in better economy elsewhere (like tyres or somewhere else) which negates the loss from running an engine in warmer ambient temperature.

When cruising a petrol engine is probably operating at less than half throttle..... cold air makes a difference at full throttle no doubt when accelerating hard.

A diesel loves air but 20 deg C air isn't that hot anyway
