check out these from Office Works !
They are actually water bottles 1600cc capacity (which means I under filled the last oil change
) . They were once available as an individual but when i went to go buy again, think I had to buy a dozen in a box !Makes for easy dispensing from 20 litre drums and ease of pouring into our odd Subie fill necks
(40mm pavers more like it, or reduced further - banished to working on crushed brick not quite the dirt floor farm shed though
