Just a quick update, by first tank of gas (700 km) burnt through about 0.5L of oil so I replaced the PCV Valve, which I found was not functioning correctly and have went another 1000 km so far with no consumption and averaging 28.0 mpg. Not too bad for something with 300k on it. And I'm running 5w-20.

I do have a question though. I have brand new tires size 215-60-15 for the summer. The stock tires are 195-65-15 on 15x6 rims, I know the tires will look 'bubbly' but will there be any clearence issues if I try to run these? I need to know now so I can figure out whether or not to sell them. Thanks guys!
