Coleman lamp musings

It's been a long while since I've needed coleman fuel.... & OMG the price of Holts brake cleaner has shot upwards! / thank you Russia-Truss-Kwarteng?
I use loads of it & shelf-life is many yrs, so I thought £52.39 (with a limited period 'SPEND8' discount code) for 25L delivered was a good price. Works out at £2.10/L. Delivered by DHL today & can confirm it's the good naphtha stuff & works great for our coleman lamps. Will keep me going for a while...
