IIRC, Rob Jax (who was a genuine expert on matters fuel) reckoned that the premium petrol wasn't worth buying because it really had no effect (the mind is a very strong influence..) but that the premium diesel did offer a very minor improvement.
I did try both, being the cynic I am, & concur with his conclusions. So I just use the standard stuff.
a few years ago we took a Lexus RX400h hybrid for an extended test drive. We were very impressed with its quietness and it was certainly quick off the mark. This used two electric motors and a standard petrol V6 engine.
After some discussion I made an offer for their demo, which was accepted. However, an hour or so later the manager, who we had been dealing with, 'phoned me back to say he was a bit worried about us using it for towing a fairly heavy 'van and had sought further advice from Lexus. Their feeling was that for most of the time, due to the weight, the petrol motor would be running which would result in very poor fuel economy so he couldn't advise us to continue with the purchase.
We'd previously lined up a test drive in a TDV8 Range Rover so we went ahead, and that was a completely different kettle of fish!
Nevertheless, we were both very impressed with the integrity of the Lexus manager and the Lexus itself.
Wow! nine-hour battery life for a PC laptop's very good; of course it doesn't compete with SWMBO's Macbook Air which lasts for twelve hours...
I'm sure we can all relate tales of broken computers, in fact the nightmares I had with PCs finally led me to Macs, and I've had no problems since making the change. Personally, I'm not interested in playing games but let's face it, neither Macs or PCs are good at that, they're for working on.
To the OP - just try both types and make your own mind up.
Not so. Any intel-based Mac will happily run Windows using either Boot Camp or programs such as Parallels.
I'm also a big Mac fan and between the wife and me we've an iMac, a Macbook Air with SSD, a Macbook, two iPads and a Mac Mini. They all work superbly and on the odd occasion I have to use a PC I find them a complete pain in the bum.
Just give one a try, you really won't want to go back!
Well, my Rangie was as stable as a very stable thing and towed our very heavy Knaus van immaculately all over France as well as the UK. Up & down hills. In summer and winter. With zero problems. For four years.
Cart sprung vehicles are unacceptably crude old things ( I've owned a few in the past). I really cannot imagine why anyone in their right mind would "Throw away" a Range Rover's air suspension...
I think that's the problem with "Top Gear", it used to be a serious car programme and folks associate what goes on now with "how it used to be". IMO if it's going to survive it's really going to have to change its format - it's become rather boring and stale of late.
Google is your friend here - "The Congestion Charge applies to all cars entering the Congestion Zone. If the owner of a foreign registered car does not pay, Transport for London can and does ask overseas jurisdictions for the details of ownership and can pursue outstanding charges that way. In addition TfL has vans with ANPR (automatic number plate recognition) sytems driving around London and when they spot a car with, for example, an outstanding unpaid congestion charge fee, they can and do clamp it only releasing the clamp once payment has been made."
They may now give congestion charge as the new excuse for the Dartford toll, but the money goes to the commercial company who where given responsibility for the crossing some years before the London congestion charge.
