From what I've learned so far, many oil-burning engines burn oil because of seized rings due to carbon build-up in the ring grooves. The Saturn SL series 1.9L engine seems to be one engine prone to this problem.
How hot do the ring grooves have to get before oil starts to carbonize?
Would more frequent OCIs avoid this problem or does it happen with fresh oil as soon as the pistons become hot enough?
