Same. Out of 11 WM I tired all over state found one QSFSHM in 5W 30. Ordering online or using 10W 30 in summer. Im only losing 1/8th to a quarter of a quart every 4k. Or so and my OCI'S are 5k so if it falls in the middle of the marks on the stick. I'm good. So i just use the QSFS and top off to full mark on stick with QSFSHM. Want some detergents and seal conditioners in there but don't want to run the risk of over swelling the seals
