Now that I think about it, it was probably before the pandemic. 🤔
I only changed it once with the extra can I bought with the mower but never since. I’d imagine it easily costing somewhere around 20 to 30 euros a year so that’ll pretty much cover a new mower every 10 years.
Lawnmowers only take about 16oz of oil and you can buy 5qts(160oz) for $23 here in the states. So that $23 would last 10 years of oil changes if you replace it once per season like I did.
Not sure what that would cost you in Europe. So maybe that’s where the disconnect is.
