In Topic: Mondeo Mk4 Tyres

29 June 2015 - 09:25 AM

All tyres have advantages and disadvantages. As it happens, those sport Maxx RTs are good for noise, fuel economy, wet grip, etc, but at the price of wear. If that's not a compromise that suits you, you won't like them.

 

(Also, on a side note, fronts do wear a lot more heavily than rears. My preference is just to accept that the fronts need changing more often, and to replace two tyres at a time, but people do swap them around, to equalise wear. That seems to imply that you will change four tyres at once, and that can be more painful.)

 

You might want to say which Contis you had on your Mk III and in what size, and what you didn't like about them. There are appreciable differences between Eco Contacts, Premium Contacts and Sport Contacts, and even between SC3s and SC5s. In any case, SC5s are good tyres, which are probably not what you want (probably the best braking performance of any available road tyre, and decent fuel economy, but at the price of some noise, and, if you use the grip, they can wear pretty quickly).

 

If you want to go for something that wears better, there will be compromises that have to be made, most likely in wet grip and in grip, more generally, and there may even be losses in fuel economy (reduced FE is very commonly a compromise in the cheaper options...so, on more of a system wide basis, are these tyres really cheaper???).

 

If you want longer life, and don't mind paying in purchase price for it (and aren't prepared to go for cardboard-like, no wet grip, really cheap options), then something like a Michelin Primacy 3 might be good (but, not cheap).

 

There would be some mid-range tyres that you should consider: Barum Bravuris 3 (err, quite like an SC5, but cheaper, which might put you off; there is an HM and a non-HM version, and I'm a bit unclear on the exact differences), Vrederstein Ultrac Cento, Kumho KU39 come to mind.

 

There are also some 'eco' tyres; Pirelli Cinturato Blue, Dunlop Blu Response - these will give good fuel economy, but I am less sure about the wear lifetime, but, if total cost is your focus, these are probably good, and don't have the poor wet grip of some earlier fuel economy tyres.

 

Sorry, meant to add:

 

Goodyears - probably not F1 assy 2, with your set of priorities, but Efficient Grips ought to be good, but on the expensive side, and not really top in anything in particular, and, while the wear life is probably rather better than the Dunlops, there probably are better wearing tyres out there.

 

And, in general, the extra load/97 rated tyres are much easier to recommend than 94 rated on a vehicle as heavy (fully loaded) as the Mondy; which is a slight shame, as, eg, Toyo CF2s seem only to be available in the lower rated size, and they are otherwise quite good.

 

If you can describe something about your priorities in detail, maybe something else will come to mind.


In Topic: Matrix Turn Signals For Mk4fl - What Do You Think?

21 June 2015 - 08:03 AM

If, as it seems, your intention is to sell this as a product, there would be a whole load of requirements to meet, depending on where you would be intending marketing this; eg, all of the EU automotive marking requirements (which imply all the stuff like EMC and other environmental testing, etc, and that's not cheap), and things like ISO 7637. 

 

(You don't say where you are located, other than 'Non-UK', and there may be local regulations there, that may or may not be relevant. If that is in the EU, and that's where you intend selling it, then there is good news and bad news; the good news is that there is a single set of regs covering the EU, the bad news is that the regs really are quite extensive and require formal product reviews, etc.)

 

In general, it really isn't worth it, for something like this, so you may want to think of another approach.

Is the immobiliser doing the right thing (presumably, whatever it used to do)?


In Topic: Odd Gear Change Problem

17 June 2015 - 06:59 PM

Hmm. When I were a lad, we was learnt to go down the gears one at a time, so you have to say that is a possibility, even if it is not what you want to do.

 

Presumably, the change gets more co-operative if you double de-clutch?

 

OTOH, it is possible that the synchro is worn and not as powerful as it would be on a new car (all this missing out gears!), but as you'd have to disassemble the gearbox to do anything about that, you might choose to ignore that possibility.

 

Another possibility, particularly if the gear change is worse when the oil is cold, is that the oil needs changing. How many miles has the car done?


In Topic: Performance Fuels

17 June 2015 - 06:49 PM

What is everyones opinion on performance fuels such as V-Power etc?

 

Worth it or not and why?

 

Depends. I've always used decent fuel - mostly - and a splash of RedEx, but I've recently tried an experiment with Vpower Diesel (in a Diesel Mondeo).

 

My conclusion is that while the car does run better on the Vpower, if you are looking for increased mpg to pay for the use of more expensive fuel, it doesn't quite do that.

 

On the other hand, it seems to smoke a bit less if you welly it, and it does run a bit more smoothly (it is easy to deceive yourself about this, but on a couple of occasions, I've just been driving down the road and thought 'my, the car is running smoothly today' before remembering what I had done differently). Not quite sure what happens if you, say, run it on 50:50 Vpower and ordinary fuel (with or without a splash of additive), but that might work well. (Or, not, of course, haven't tried it).

 

So, if you are trying to save money on fuel, it probably doesn't quite get there. If, on the other hand, you are trying to look after the car more generally, the fact that it smokes less and runs that bit smoother may well make up for that (and there may be, due to lower smoke, fewer regens, and as fuel economy does take a hit during a regen, that might push the numbers a bit closer to break even).

 

I used to be pretty cynical about the 'pay ten pence extra for better fuels' deal, but now I'd say, financially, there isn't much in it. Not sure about, eg, Esso, BP, Total, etc, but Shell gets a cautious recommend from me.
