If you are like me and do work on vehicles at home like changing oil, adding windshield washer fluids, etc than boy do I have the perfect oil to be used to change yours at home in the comfort of your garage, shop, or even in your driveway or grass. I'm always tinkering with mine and my family's vehicles and one thing I always remember to do is to change the oil as it approaches the mileage recommended. While I've used different brands in the past Pennzoil Full Synthetic is top notch in my book! I get the box containing 6, 1 QT bottles of Pennzoil Full Synthetic 5W-20 which gives your vehicle 40% better performance than conventional motor oil. Although this brand has many varieties this particular one offers not only better fuel economy but it will go longer between oil changes, protection in extreme temperatures, conditions older seals as well as protection against sludge & deposit build up. Those being my main concern with my wife and teenagers driving. It's an amazing feeling knowing this trusted company had any consumers worries to a minimum of not gone completely! I am a repeat Pennzoil purchaser but think I'll continue using this particular one for adding oil to doing the works with helping my family with complete oil changes.

I changed my oil with this Pennzoil Full Synthetic oil and will update this review in two and a half months after I complete another oil change. I put my old oil in an airtight container and will compare the Pennzoil to that once I do my next oil change. I have no other way of knowing how well the Pennzoil works other than to compare it to the brand I regularly use. I'll be back! My wife says I can't update reviews, so I will complete another review after my next oil change.
