[This review was collected as part of a promotion.] Engine oils Came in 1 qt 6 packs, took it to my mechanic, they changed it into my 100k Toyota Camry, and got it inspected. I’ve been driving it 80 miles a day, from Long Island to nyc, back and forth, no problem , running smoothly.

[This review was collected as part of a promotion.] I have used different brands of oil in my vehicles over the years but the brand I keep coming back to is Pennzoil. Their full synthetic oil keeps my engine running smooth and I seem to get better fuel economy with it. I'll keep using the brand I trust.

[This review was collected as part of a promotion.] When it comes to adding life to your engine the one single thing you can do is keep the oil changed! Oil is the life of your engine regardless if it’s your automobile or your lawnmower. This Pennzoil full synthetic is a great oil and is 100% synthetic that provides better fuel economy and great wear protection. I highly recommend this oil.

[This review was collected as part of a promotion.] This motor oil works great for my car. I used it for an oil change and had no problems. I also love the handles which makes it easy to carry. The scent is overpowering but its to be expected with motor oil

[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 switched to this after using a competitor's full synthetic, and have noticed a difference in my higher milage car. The idle is significantly smoother, as well as engine noise has been reduced. I'm looking forward to harsher driving conditions this summer due to additional heat to put it to the test, but as of now, I have no worries its up to the challenge!

[This review was collected as part of a promotion.] This Pennzoil Full Synthetic Oil makes my car run great and smooth. It’s your entry level synthetic oil, but Pennzoil does a great job at making a true synthetic oil so you know you are getting the real thing. I like the design of the packaging and the consistency of the oil, it’s a quality product throughout. I highly recommend this oil to anyone looking for a high quality, long lasting synthetic oil for their vehicle.

[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.] We have several older vehicles and when we started using it our cars started running better and more efficient. We highly recommend this product to our friends and family. It is very cost effective. We bought a whole case.
