Long legged 1.6
I'm very impressed with the way the 1.6 engine handles high speeds. I have done nearly 800 miles in the space of a week travelling to interviews in the south east (I love the M3 when it's clear!). The car has the ability to sit at 100mph 5000 rpm non stop for hours on end and is far more composed than any other 1.6 at this speed, even the Honda vtecs. Just one gripe/question, I switched from 5W40 full synth to 10W60 racing a while ago and the oil consumption seems to have gone up a bit if anything! It has made no difference and my car still goes through about 1L per 1000 miles.
I bought the car at 39K miles and was sure the thicker oil would make some difference, but it hasnt. Does this mean I may have piston ring probs or something? Maybe the car wasnt run in properly by the previous owner (it was ex fleet) or it was oil starved at some point? Can someone put my mind at rest.
