Hi guys! I'm Bart from uk, Im Pole so sorry about my english I doing my best. I just owned (in 2017) mazda3 2005 2L Sport. I never had other car than fiats In my life. Im quite disapointed with oil consumption but I don't blame make. My one got 73k miles on clock and it uses les and les oil since I bought it. 3 months ago it burns about 1-2L per 100 miles. A lot of blue heavy smoke from tail pipe. Recently I changed oil for a 3rd time. It was soooo dark black colour only 1000 miles done. I started with changing pcv valve. And then i realised there is something knakered in engine. It's very strange for me that 73k banger got stuck or worn out piston rings. I fighting with this issue and soon I gona post my results how I repair my sportyhatch. Thanks Bart
