This is a nice strawman argument. Nobody claimed that the there was a shortage of 100 octane stocks, however there were uncertainities with consistent supplies, partly due to U-boot activity and partly due to dependence on US manufacturers, their capacity and willingness; this is clearly noted by a dozen British historians like Morgan and Shacklady or the official studies. You ignore them all.

Tanker losses to all causes, I have gathered a total of 78(!!) tankers were sunk by mine, U-boot (typically), aircraft and raiders, between September 1939 and November 1940. About 90% of them were British, though there are a couple of Swedish, Dutch, French etc. tankers
Tanker losses were serious, unfortunately.

"The process of bringing Norwegian tankers under Allied control has advanced during the week, and of a total fleet of 212 Norwegian tankers 119 are now under Allied control, while 18 are proceeding to Allied ports; 93 are in neutral ports or reported to be proceeding to neutral ports..."

Meaning in April 1940 Britain had already gained the use of 119 Norwegian tankers, 41 more than were sunk between Sept 1939 and November 1940, and more were expected.

cab68/7/31 "War Cabinet Oil Position Monthly Report: November 1940" (issued 20 December) (http://www.nationalarchives.gov.uk/r...-1939-1945.htm)


Table I: "Imports Into the United Kingdom (Services and Civil)"

Shows the total number of tankers arriving in UK ports in the year between September 1939 and August 1940 = 947: (Total shown in table = 1,079 minus 132, June to August 1939.)

March to May 1940 = 109 tankers; 1,112,300 tons imported;
June to August = 100 tankers; 1,058,900 tons

total tonnage of oil products imported = 9,986,900. (11,126,900 minus 1,140,000 tons, imported June to August 1939.): an average of 10,546 tons per tanker.

September and October 1940: 124 tankers (62 per month) arrived and in November 80: September = 640,500 tons of imports; October = 651,600; November = 890,300 tons

Grand Total of Tankers arriving in UK Sept 1939 to November 1940 = 1,151
Grand Total of Oil Products Imported = 12,169,300 tons: 10,573 tons of oil product per tanker

Total number sunk Sept 1939 - Nov 1940 = 78(!!); 385,957 tons of oil product = roughly 6.8% tankers; roughly 3.2% of tons imported to Britain. The amount of oil product per tanker destroyed was 4,948 tons, meaning on average the tankers sunk were carrying less than half the weight of cargo each tanker that arrived in port was discharging; the tankers being sunk were either smaller than average, or, more likely, at least half of them were sunk in ballast.

Quantity of fuel available ( production estimates) from non US sources as of November 1940

Heysham 150,000 tons
Trinidad 80,000 tons
Billingham 15,000 tons
Stanlow 55,000 tons
Abadan 50,000 tons
Aruba 50,000 tons
Palembang 50,000 tons
Pladjoe 50,000 tons

When Barbi starts trolling, you know that he is squirming like a worm skewered on a fishing hook.

His 2cd image is of American 4 stack destroyers laying a smokescreen, which he is doing.

It can be put to rest that the stations listed in the Dec 7 1939 document did indeed get 100 octane fuel, except possibly one.
