[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 used this to change the oil in my truck with over 2000 thousand miles. Had no problems with it at all. Drove it about a week. And check it and it looked nice and clean. Will definitely be using for my vehicles from now one.

[This review was collected as part of a promotion.] I've been using this on my truck for a while now. It's getting a little long in the tooth (it's a 2005 model) and I want to prolong it's life as much as I can since I don't plan on buying another truck for a while. Full synthetic like this is the way to go. I've had no problems (knock on wood), so I just keep doing everything the way to maintain the truck for many more years to come. Thanks, Pennzoil!

[This review was collected as part of a promotion.] I’ve always used penzoil and bought my daughter a car a few months back and figured I’d try the synthetic this time. It’s a fantastic product and will protect my daughters car for miles to come and put my mind at ease.

[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.] Pennzoil is a brand that I have always admired. I use it with the confidence because quality is in it's name. There are many brands to chose from but you will never go wrong using Pennzoil Synthetic. It's a name that's been around a long time and you can trust that.

[This review was collected as part of a promotion.] While its hard to notice a difference between various oils, I "feel" like the Pennzoil synthetic makes the car run quieter. The difference is very small but I do feel like I notice a difference when I use it. It does pour out very easy and doesn't spill too bad. I highly recommend Pennzoil Synthetic oil!

[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.] Had no problems with this Pennzoil Full Synthetic oil. Used it to change my oil. Easy to open and close. Easy to use. Comes out great. My van runs nice. I would recommend this product to all my friends.

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