[This review was collected as part of a promotion.] This Pennzoil Full Synthetic oil was super easy to use it made for great performance in my vehicle. It was easy to distribute with the shape of the bottle. I absolutely stand behind this brand. I would not turn to anything else.

[This review was collected as part of a promotion.] Used this in my last oil change for my Mazda 6 before doing some travel this summer. The car continues to run great, and the oil still looked clean when I checked it after running about 1000 miles in the heat. Oil is a hard to review, because it is one of those things you only pay attention to when it is not working, but I'm happy to report that this full synthetic has worked great for me.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic Oil is tough stuff. This oil puts up with the real deal drive it like you stole it abuse. Dump the old and refill the life juice of your engine with this great stuff. came out looking like it went in. its a great reliable choice for all performance machines.

[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.] 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.] It took me a bit to write the review as I had nothing needing an oil change. But this summer's start of camping season changed that! I really love the double handle option on the bottles, it really makes options for pouring the bottles very easy. As far as performance, I will have to get back after some miles have been put on.

[This review was collected as part of a promotion.] I have used only Pennzoil products in my vehicles for years, it’s a trusted brand that always delivers. I’ve never had any issues with Pennzoil, and would highly recommend their products to everyone that would listen

[This review was collected as part of a promotion.] This is a great motor oil! I use it in my car and it runs a lot better now! I recommend it to all of my friends and family that have cars or other vehicles that require the use of motor oil! It’s really great!

[This review was collected as part of a promotion.] I exclusively use Pennzoil for my car, and it hasn't let me down yet. The engine performs the same or better in this than with the oil recommended by the manufacturer; the Pennzoil almost makes the engine "purr" softly when idle. From what I've read in studies of different oil manufacturers by independent third parties, Pennzoil is in the top 3-4 overall oils when it comes to engine wear, how clean it keeps the engine, and resistance to breakdown. In other words, it appears to be exceptional value for the quality of the oil.

[This review was collected as part of a promotion.] I recently tried Pennzoil full synthetic 5w20. After I changed my oil and filter I noticed more power during acceleration and less delay in my engine. I highly recommend Pennzoil products to bring your vehicle to life.
