[This review was collected as part of a promotion.] We all know Pennzoil stands by their name. I will not go with any other brand. The price is more than worth it. I feel like If I can trust this brand so can everyone else. Please spend the extra amount on Pennzoil it is more than worth it.

[This review was collected as part of a promotion.] I've always used synthetic oils in all my cars for the extended oil change interval and better protection against viscosity breakdown. The Pennzoil Full Synthetic is just as good as any of the more expensive options like Mobil-1 or Castrol. Oil changes are a great way to keep a car running for a long time and with this oil, I'm not worried about being a few hundred or even a thousand miles late for an oil change.

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic is my oil of choice when it comes to all my lawn and garden equipment. I truly trust this oil and know that it will perform at its best and keep my equipment running at peek performance. The full synthetic is what I prefer to use and I know the Pennzoil brand is a name I can trust for ongoing performance. Highly recommend

[This review was collected as part of a promotion.] I switched over to this Pennzoil Full Synthetic oil for my older riding lawn mower. It's better for the engine and I love the fact I have to change it less frequently. My mower seems to run smoother since the switch. Pennzoil is a brand I trust and will continue using. Highly recommended!

[This review was collected as part of a promotion.] This is great oil, definitely prefer this over any thing else on the market. Super clean, engine has been running amazing. Will continue to use this synthetic oil for many more years to come. I absolutely recommend this product if you're looking to switch over from any other kind, especially if you're getting over that high mile threshold.

[This review was collected as part of a promotion.] I have a Lexus ct200h. I can begin to tell when the oil is getting old as the car begins to lag a bit and the mileage is a bit lower. The Pennzoil Full Synthetic did the trick on making the engine run smoother and my mileage has ticked up a bit as well.

[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 desperately needed oil for my truck and I only use synthetic so this couldn’t have come at a better time. And I Already tell a difference in performance. Pen soil is awesome!! My truck purrs like a kitten
