Which engine was fitted on the Mammoth Major in 1934? Was it a 92 bhp 7.6 litres diesel?

That particular Mammoth Major has a AEC 6-cylinder petrol engine. It is also the very first factory built eight-wheeler into service, that is why it’s owned by the Science Museum. There might have been earlier eight-wheelers in service by a few weeks but they were rough conversions of six-wheelers with a fourth axle fitted. The 1933 Construction and Use Regs. allowed four axle rigids for the first time. Sentinel also built some eight wheeler steam waggons at the same time. Leyland and ERF quickly followed AEC into the eight-wheeler market.

I was thinking that it had a petrol engine as it looks like an oil cooler underneath which I don’t think the diesels had?
