The last Michelins I fitted to my 'Munich airport taxi' (which will be the last ones I buy for this car) appeared to be half worn when new, and proved not to be good value, the rears wore out in 9,000 miles and the fronts in 18,000. Not good value.
I approached Witter to get a tow bar fitted, they quoted about £600.
I then went to a tow bar specialist who charged me £430 for the same thing.
When I told them what I had been quoted by Witter, he just shrugged his shoulders and said 'they do'
Buy a Witter bar from a dealer, made for the car...
The most MPG I have seen on my S204 was 50.5, that was achieved after 120 miles or so.
I get the impression the figure continues climbing the longer you drive in one go, the sky would be the limit if you have a good bladder!
Not too much to worry about, aviation personnel have been running their Diesel cars on Jet A1 Kerosene mixed with Diesel since time immemorial.
You can also use a kerosene mix in your petrol powered car, but its a bit smokey and smells.....plus you upset the Police and HMRC.
I am a retired, licenced aircraft maintenance engineer with 50 years experience, who was held legally responsible for the maintenance carried out,...... and I should not be allowed to maintain my own car??
The bottom line is, an owner of a vehicle, driven on the public roads, is legally...
My brother in law had an old Ford popular that breathed a lot from the crankcase,
he too fitted a piece of hose to take the problem to the back bumper.
All was well for a couple of days, then the crankcase cracked due to the back pressure!
