[This review was collected as part of a promotion.] 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.

[This review was collected as part of a promotion.] I have been using Pennzoil motor for as long as I can remember. It has always done me good and never had issues with my motors in any of the cars I've owned. This full synthetic oil is absolutely the best in my opinion. Excellent in preventing engine wear, resistant to both over heating and freezing and is very high performance. I owned a Firebird and Camaro. A good plus is that its recyclable. I like that it comes in a 5 quart jug and the jug has 2 handles to grab onto. Also, the price is competitive to other synthetic motor oils. The best!

[This review was collected as part of a promotion.] I always get Pennzoil for my car. I have to get the full synthetic since my car is foreign. Got this to do my own oil change and my car runs great. My car is getting higher in miles so will have to go with higher mileage oil next time.

[This review was collected as part of a promotion.] I got 6 quarts of Pennzoil Full Synthetic. I changed the oil in my car and used this for the replacement. I don't know if this is possible but after about 10days of use I truly think I am getting better gas milage. The car runs quieter than before. This is a good product and everyone should be using a synthetic in their car.

[This review was collected as part of a promotion.] It took me a bit to write the review as I had nothing needing an oil change. But this summer's start of camping season changed that! I really love the double handle option on the bottles, it really makes options for pouring the bottles very easy. As far as performance, I will have to get back after some miles have been put on.

[This review was collected as part of a promotion.] Its exactly as expected. Its a brand I trust and use quite often. It comes in convenient bottles that is easily poured. Just the amount needed to change my oil. Its great. It keeps my car running properly. I would definitely recommend this brand.

[This review was collected as part of a promotion.] This Pennzoil Full Synthetic Oil is high quality, affordable, and made by the best in the business; Pennzoil! I love the design of the bottle as well for a nice even and smooth pour. The additional handle comes in handy when putting it into the funnel.

[This review was collected as part of a promotion.] I drive a 2008 and it has some issues, so I like to use full synthetic oil instead of conventional oil. The full synthetic oil I feel is just a better oil for my car. I feel it lasts longer and just is all around better. I use the same for my daughter's 2001. And Pennzoil is my preferred brand.

[This review was collected as part of a promotion.] I have been a valvoline user for years but then I happened to try this Pennzoil Full Synthetic and I am I happy I did. I can just feel my Jeep running smoother. It starts with ease and runs like a champ and I will be sticking with Pennzoil Full Synthetic.

[This review was collected as part of a promotion.] I prefer using a full synthetic oil in my cars. This Pennzoil 5W-30 has worked well and I have had no issues with it. The bigger jugs make it easy to pour in and cuts down on plastic with the smaller bottles. I recommend this full synthetic oil.
