I've been looking at oils at Canadian Tire and Walmart recently. It struck me how odd we have it here in bottle sizes. Some are in US quarts, some in US gallons, many in 1 litre bottles and 5 litre jugs, rare 5 US gallon pails (18.9 litres), only one 2.5 gallon jug (Rotella T), and then quite a few in 4.4 litre jugs.
Why does engine oil come in 4.4 litre jugs?
It seems like a odd number for a one-bottle-per-engine type of size, it calculates to 4.65 US quarts, or 3.89 Imperial quarts. Do the oil companies spec bottle sizes, or do the bottle manufacturers have standard sizes the oil companies use, perhaps cheaper than custom sizes?
