Yaris burning oil

[Ramon1691]

In only went down a few lines like 3 or so a little down from the full mark I have after 1800 miles with the synthetic also I don't know whether the previous owner kept up with the oil changes that well when I bought it I did a whole tune up on it I'm just going to stick to conventional as you mentioned and just going to keep an eye on the oil every month or so I had my mechanic check the pcv valve and it was good I seen this cars last many miles I also got my serpentine belt done that bastard was full of cracks :/
