[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 is the only brand and type of oil I use in my truck and trust Penzoil over any other brand. My truck alwasy runs smoother, cleaner and gets better gas mileage with Penzoil. Whether you do a DIY oil change or not - this is the oil to go with here guys

[This review was collected as part of a promotion.] Pennzoil® Full Synthetic engine oil is a full engineered engine oil that is appropriate for use in new and more established motors. It is detailed to give 40% preferable execution over traditional engine oil1 and permits less oil changes contrasted with customary engine oil. Along these lines, if your vehicle as of now requires full engineered, or in case you're hoping to update from traditional or manufactured mix Pennzoil® Full Synthetic is the correct decision for you.

[This review was collected as part of a promotion.] I started using pennzoils full synthetic oil on both my trucks about a year ago. Long lasting...I typically go about 7,500 miles between oil changes and the oil still looks good when I drain it. Could probably go another 7,500. Not all oils are of the highest quality as pennzoil

[This review was collected as part of a promotion.] I wanted to start using a full synthetic oil for my vehicles. I wanted a name brand that I could trust. I have used Pennzoil for 45 years. I have used it in every vehicle that I have owned. Changing to synthetic oil for me with the amount of travel I do now yearly makes sense. Going longer between oil changes and the heat protection it will provide are the key reason for the change. Convenient six pack is right for me.

[This review was collected as part of a promotion.] This oil is great! After switching to this oil I can tell my engine feels like it runs better and sounds better too also I am getting better MPG now. This will be my go to oil for all my cars. For the price and the benefits, this is a great deal
