[This review was collected as part of a promotion.] This is my favorite oil. It out preforms all the other oil brands in my book. If you don’t get your oil changed every 3,000 miles this oil will help keep your car moving. It’s just the best in my book.

[This review was collected as part of a promotion.] Pennzoil helps to keep my Buick on the road. While I'm not that great of a driver to notice every little difference an oil makes, Pennzoil has always been a quality brand. I use the 5W-30 to top off my car if I notice the oil goes below the fill line before I get to my mechanic. It's a Mom N Pop place and you can bring your own oil along for the oil change. I like that this Pennzoil gives me more miles between changes and keeps my engine running smoothly. 

[This review was collected as part of a promotion.] I used this to change the oil at home in my car and had no problems using it. The jug has two areas you can use as handles which is nice so you can tilt it all the way to get it all poured out. It has my car running great just like it should.

[This review was collected as part of a promotion.] This is a great oil. I have used it on foreign and domestic cars with over 100,000 miles. Always last long and a good choice overall. I will definitely continue using pennzoil products in the future..

[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.] Pennzoil is by far the best engine oil I’ve used so far. I feel much better putting this oil in my car. I’ve gotten great performance from my car. The engine sounds great and runs smoothly. This is a great oil for my car.

[This review was collected as part of a promotion.] Time and time again, this oil impresses. It holds its lubricating capacity better then most whilst being very affordable. I have worked on cars for 30 years and this is my go to oil. What more could one desire..

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic Oil seems to be a great motor oil for my vehicle. The contents of the container is easy to pour into my engine. My vehicle seems to run well. I am impressed with oil because I have never used this oil before.

[This review was collected as part of a promotion.] As a long-time customer of Pennzoil, I value the quality and consistency of their full synthetics to keep my motor clean and running. This product is up to par with the Pennzoil I've used in the past, and I wouldn't expect anything less! A great American company putting out quality products!

[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.
