Before I swapped out the engine and gearbox, my 1989 escort 1.3 popular used to do about 100miles to the pint. Of oil.
It was great for disposing of used engine oil.
I had a (very knackered) Ital van for work when I first started. It would start the day with all fluids topped up, and at lunchtime, I'd pour in 2l of oil and 2l of
coolant water, which would usually see me through until the next morning, when it would be topped up again.
It only did between 150-200 miles a day
