Elio Addict
I posted about using Mobil 15 K motor oil. And this is what I did. After examining the oil at 10 K miles, it was a little darker, but very clean. So I changed my filter which is a 10 K mile filter. The filter is on top of the engine on my pre-runner so it is easy to change it. Will drive it for another 5 K before changing the Oil and filter.
