I had initially (in that post) written that I removed 7 qrts but on re-reading the thread realised it had only been 5 litres so I edited the post to correct that, and mentioned the edit for anyone (you!) who had read it before the correction.What do you mean by “note the correction made there…”?
My point being, that although your 4 qrts is on the short side it is only around 1 qrt shy of what I removed which was the correct amount. Which is a whole lot better than being 3 qrts adrift which my pre-corrected post made it look like.
What condition is your removed fluid in? Does it look tortured or unscathed?
