I was appalled to discover that the Vauxhall recommended oil for my 1.8 Vectra 2006+, costs something like £60 for a 5L can. Good GOD!! Now, Halfords sell oil which they declare to be suitable for most modern cars for a fraction of that price. Given that my car travels less that 1000 miles a year, and certainly not at 100 mph, 'cos I is elderly(ish), would anyone suppose that I could/not use that sort of oil, which I could, possibly, afford? It hasn't had an oil change for about 3 years now - can't afford it, can I? GOG
