Annual service time, P2 due however as I have a reusable multilayer foam panel filter, a quick shake n vac was all that's needed. Wipers rotated and tyre pressures checked.
Having replaced the valve covers recently, I was shocked to see the amount of oil which remains in the heads regardless of whether the sump plug was in or out. Effectively there's always a handover of 12 month old oil that'll contaminate the new and continue for another stint.
I had the idea to carry out a flushing oil change and as I was going from Castrol Edge back to Millers Trident, I wanted a minimal handover.
New oil put in and ran for 20mins before draining. Oil filter removed and drained also.

Flushing oil on the left, 12 month old oil on the right. To think that flushing oil I'd have asked to look after my engine for the next 12 months 😳
Fresh oil poured in for the second time, ran for a couple minutes and I've never seen the dip stick so clean. If you've never done it, for the price of a tub of oil do it - she's worth it
