Never use flush unless you plan to then remove the sump and clean the oil strainer. As for the price and the statement regarding not being able to buy the oil for that piece, ask yourself........why?
because hes only buying 6 liters amd they buy 60000!
plus hes buying good stuff!
We pay about £1.30 a litre, and that's only a 200l drum. Add in a filter at £1(ish), and that makes the consumables cost of an Omega oil change £8.50.
Buying in bulk makes a huge difference!
The key point is that you can only get a basic oil for that price even in bulk (which seems to make not nearly as much difference as you would expect because its not really bulk, its still pretty small quantities)
Well, it's 5w30 fully synthetic, which I find hard to call basic. But you're right, my point was even a small quantity like 200l(which lasted us less than a month) is
much cheaper than buying it in 5l containers. And that is what makes the £25 oil change possible.
Personally, I've never found any difference between brands and used cheap diesel spec 20w40 oil on any solid lifter engine for years. That's because I simply took it off the shelf at work. It's only the last 3 cars - a 525, Legnum and the Omega - where I worry about the oil spec as they all have hydraulic lifters.
Nor can I see any reason to change it as often as many of the members here; I thought the whole point of semi/fully synthetic oil was that it stayed in grade for longer? Which makes changing it every 3000 miles an extravagance. For all the fretting on here about oil changes, I'm surprised that no-one has suggested having the old oil analysed. 10 -12,000 or annually(whichever comes first)has always worked well for me, and I'm not likely to change now. That was the case when I was doing over 30,000 miles a year which meant 3 changes every 14 months, or the less than 10,000 that I do now which means once a year. It's due at the end of January, and so far the level hasn't changed since I last did the job, and it's still clean and clear. Which is good enough for me!
