Not necessarily, since they rollback conventional oils as well. $12 for a jug of MS5k is as atteactive to a conventional oil user as is $22 for M1 to the syn end user. To each his or her own.
So you switched to QSUD, thats a good choice for sure, especially since Hyundai recommends it. To the OP, I think these prices are a great reason to switch to a synthetic. You can have a full synthetic oil change (including full synthetic Fram Ultra oil filter) for under $30 easily. That cheaper than going to a shop and getting it changed with cheap oil and cheap filters.
