[This review was collected as part of a promotion.] Bought this when i was down a quart . Worked well. Had the oil changed about 45 days later. No issues.

I had a lifter noise at start up. I changed brands of oil to Pennzoil and my lifter noise disappeared! Nobody will EVER tell me oil doesn't make a difference! A great product and will NEVER use another oil! Thank you Pennzoil.
