It literally costs less than a bottle of good oilJason QLD
Compare the costs over 100,000km for a Toyota 100 Series Landcruiser 6 cylinder petrol.
Don't forget, an EZ Oil Drain Valve is a once only cost. You install it and never have to replace or service it.
Genuine wiper blade inserts (drivers, passenger, rear) replaced every 20,000km. Genuine Oil filter replaced every 7,000km with oil change. Premium quality mineral oil (2 x 5L bottles required) changed every 7,000km (some prefer more frequent changes e.g. 5000km). Fuel prices fluctuate.
