[This review was collected as part of a promotion.] I got this and I change my oil and use this and so far has given me great miles without any problems. It is a very good oil to use and it is very expensive but it is a very great product. I will definitely recommend this to everyone that i know and i will continue to use this from now on.

[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.] This is a great product from Pennzoil. The quality of the oil after 5,000 miles is great. It wasnt watery so the viscosity holds up great. Great synthetic oil you can trust. I'll keep using Pennzoil for all my vehicles.

[This review was collected as part of a promotion.] I have never tried the synthetic oil previous to this. I heard rumors to stay away from synthetics in the past. My son in law is a farmer,( they use a lot ) and he is the one that convinced me to try it. I have it in my riding mower and truck. I guess I had some bad information.

[This review was collected as part of a promotion.] I picked this up to save a trip to the mechanic. I love the way this oil last longer than regular oil and it’s not that much more expensive. I highly recommend it to anyone wanting to change their own oil

[This review was collected as part of a promotion.] Full synthetic is great for my wife's car. Got these to keep in her trunk, she gets paranoid when her oil goes below 15 percent so she can keep this for those days. Until I can get around to doing the oil change.

[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 used this pennzoil in my last oil change and it made a big difference in performance and engine noise. It stayed cleaner longer for better protection. I like the convenient 5 quart jug which makes filling up simpler. I would definitely recommend giving this a try specially for the value you get at the price point.

[This review was collected as part of a promotion.] I have been a valvoline user for years but then I happened to try this Pennzoil Full Synthetic and I am I happy I did. I can just feel my Jeep running smoother. It starts with ease and runs like a champ and I will be sticking with Pennzoil Full Synthetic.

[This review was collected as part of a promotion.] I've been using Pennzoil oil for a very long time. And now that our Honda is getting a bit up there in age and wear, I decided I wanted to transition to synthetic oil. Since I e made the transition, I've noticed a slight increase in fuel efficiency and how the engine runs. I'm excited to see how well it performs as the year goes on, but I know I can always trust Pennzoil, so I'm expecting solid results!
