I doubt that is proof of one oil weight superiority over another even if the engines were similar there are too many variables.that said, Shell Rotella T-6 full synthetic comes in 5W 40 and 5W 30 we have used 5W 40 in all our vehicles for years w/ great results. if your engine uses a qt between oil changes it may have an issue but what is your interval? sounds like you may have bad rings or bad valve guide seals or? but then I recall reading about new BMW'S using qts. of oil and owners were not happy! BMW said it was all good! there is usually a good reason, = something is wrong if the engine uses a lot of oil eh? my saabs hardly use any but as the saying goes "your experience may not be typical "
