How many more blogs and websites will perpetuate this myth that most tanks of the time ran on diesel, while the Sherman ran on gasoline? Its simply not true. With only a small number of exceptions, American, British and German tanks ran on gasoline. Only the Soviets made widespread use of diesel, and their T-34s had a far worse crew survival rate. The vast majority of burnt out Shermans were found with intact fuel tanks.
Once this was understood, main gun ammunition was moved from the vulnerable side sponsons, to the turret floor, and was given wet stowage. This reduced the number of fires by about 75%.
