I just picked up a case of QSGB for a buck a quart at an autozone on clearance. I drive around 40 miles a day total in heavy houston stop and go traffic. Every few weeks I make a long trip of 200-300 miles. I typically run 5k OCI's with blend or syn. Should I continue to run 5k OCI with QSGB? 2009 f150 3v 5.4 with 100k miles.
