I'm hoping it's just because i've missed a service or 2 due to being flat broke. My oil is not a pretty colour. There's no engine lights, no stalling, no jerky movements or weird engine sounds. The smoke does smell though and there's a lot but it goes after about 10 seconds. Sorry, i'm really starting to panic that i'm going to get a call from the mechanic tomorrow telling me it's going to cost me more than an arm and a leg.
