I noticed that my 172 was a bit low on fuel (Dash oil indicator looked something like this 0000_)
so I thought Id top her up with some yummy 10W50 fully synthetic but jeezus...Ive just thrown 5 litres down into her and it barely seemed to make a difference...it all just went in, and it seemed like she could have taken much more...
Have I overfilled her? will too much oil break her
