To flush or not ?

[EastPete]

Thanks Mangoman - the under tray is indeed there and in place (all 10 screws present and correct) - again, I wonder if there was more soundproofing on the under tray in earlier cars. The tray on my current late 75 seems a bit lighter and not as heavy as on my 2001 car, if I recall correctly.

Just suck out the old oil, 5 litres of it anyway, refill with cheap oil (that meets the spec) something like ECP QX oil thats often just £12 when on offer, less if you use 10w40 semi.

Drive for a bit, as long as you fancy, maybe 100 miles, then drain it properly, replace the filter and add your preferred oil.

That's the way I do it too
