Keep it up. We had a step challenge at work and I was regularly getting like 14,000-22,000 a day for the month. Now that's over I'm averaging like 5.2k a day and I should sort that.
10k isn’t bad for you. What they doing selling steps.
I would change my own oil at 3k. Better for a longer engine life, even if we can go to 6k or 10k it’s all about care of the engine. If I own it I’m looking after it.
