This morning Favourite Man checked Olivia's oil before I left for work, reporting back "if you ever wanted to take a photo of oil at a perfect level, that dipstick is it right now".
Yay! That's quite the achievement for an old Landy. Instead of emptying a couple litres into her belly every day, she's doing OK on the oil consumption at last.
Months ago I put diesel oil instead of petrol oil into her by mistake during an oil change. That probably scrubbed crud to a level where compression was lost and oil found new exits... But we added Prolong and it seems to be helping.
Today she was going very well again. Except for the wipers. Blown fuse last time, apparently the same thing this time, and another interesting bit of commute until the windscreen cleared. Favourite Man and I will be spending some time with the electrics this weekend before we take her to stretch her legs and see some whales.
For now I'm just happy the oil level's staying constant. It's amazing how much difference that makes to how she functions.
