[This review was collected as part of a promotion.] This full synthetic oil is made from natural gas and not crude oil. It helps to achieve better fuel economy. It also helps to keep the vehicle's piston clean. Overall a very well made product for your vehicle and highly recommended.

[This review was collected as part of a promotion.] I regard myself as someone who is not a rookie/novice do it yourself but not a expert. I'm always learning things and working on my own cars is 1 thing I love to do. I've used this brand in the past when going to a shop but now I do it myself and it has never gave me any problems!

[This review was collected as part of a promotion.] One of the best oils I have used in my vehicle. I’ve had no issues at all while using this oil. My vehicle runs great. I haven’t had any engine issues. My vehicle runs smoother and it doesn’t skip or anything. This is just one of those brands you can trust. I definitely will recommend this oil and always use it I’m very satisfied.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic is the only motor oil I use in my cars simply because the brand’s oil provides superior protection for your engine and enhances its performance. What’s more, the oil removes all impurities in your engine by loosening the dirt and grime stuck between the moving parts of your engine. This allows for a smoother drive and cleaner engine that performs optimally for longer. We especially love the price because synthetic oil can be pricey. Pennzoil synthetic oil is affordable and more accessible and budget-friendly to consumers.

[This review was collected as part of a promotion.] I had an oil change using the Pennzoil full synthetic oil and my car seems to run very well. The 5w -20 oil is working to keep my engine clean and protect against friction. I had my mechanic use it and my car runs great.

[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.] Ok I've been using Pennzoil for a long time now. Specially the full synthetic. I change my oil between 5k and 7k miles and I've got over 200k miles on the car. I feel like the oil is one of the reasons my car still runs strong.

[This review was collected as part of a promotion.] I use this oil in all my vehicles I think it last longer and works better during winter months. Keeps the vehicle running good don’t hear noises from like other oils that seems to run thinner after using for a month.

[This review was collected as part of a promotion.] I got this Pennzoil full synthetic to use in my f150. I usually take it to the dealer and they use a synthetic blend. Well my warranty is up so I figured I'll start changing my own oil and at the same time this will give me a chance to keep an eye on what's going on under the truck. (leaks and such) I've used pennzoil in the past on other vehicles with good results so this was pretty much a no brainer. Time will tell but with a company that's been around this long they must be doing something right!

[This review was collected as part of a promotion.] This oil is priced well, and seems to work as well as other brands I have used in the past. The oil pours smoothly and quickly unlike thicker weights of oil, and was just the right amount for my 04 acura.
