You know you're getting old when an 'all nighter' means you sleep right through till morning without getting up for a pee.

I was trained on Diesel engines which were designed for multi-fuel. Paraffin, petrol, diesel it did not matter, the Bedford TK would use whatever was available, Whiskey if you wanted. Although I can think of better uses.
That old P50 I ran on paraffin for a bet, 9:1 compression ratio, overhead cam and overhead valve, and could still run on paraffin once warm, won that £5. Who remembers TVO?
Odd but it was a siemens pump which allowed the use of multi-fuel.
The DPA (distributor fuel injection pump - Lucas) was not able to handle multi-fuels.
The Bedford 300 and 330 cu inch engine both petrol and diesel were very similar to each other. QL, RL, and TK had so many common parts.
But it was the 1970's and to remember back 50 years not so easy.
I remember TVO tractors when I was a kid on a farm. Fordson Majors and the older Standard Ford. We had some bad winters in late 1960s when the cars wouldn't start, we swung-started the Standard Ford and then towed the cars round the yard to start them. If I remember right the Fergies wouldn't run at all well on TVO. The Fords had serpentine heat-exchanger from the exhaust, which helped, but even they would only run properly if they were boiling.We live in rural Dorset, TVO was alive and well until a few years ago. Still a lot of grey TVO fergies about.

Lorry drivers used to light a fire under the sump to enable them to start. Common sight, it worked though. We lived in Kent then which tended to get a lot colder than down here in the Westcountry.
