[This review was collected as part of a promotion.] This is a great oil. I have used it on foreign and domestic cars with over 100,000 miles. Always last long and a good choice overall. I will definitely continue using pennzoil products in the future..

[This review was collected as part of a promotion.] I recently received the Pennzoil Full Synthetic motor oil and immediately noticed a difference in the way my vehicle ran after use. The oil, which is certified by the American Petroleum Institute, allows my car to run longer between oil changes and increased the fuel efficiency. Over time, choosing full synthetic compared to regular motor oil will save you plenty of money. I have even noticed a difference in the way my car drives, most likely based on the advantages this oil provides to my engine. I would highly recommend this motor oil, especially to anyone looking to protect their vehicle while also saving money in the long run.

[This review was collected as part of a promotion.] This oil is the best you can get, at least one that is affordable. It cleans, protects, and lubricates very well. Shake the oil before adding to get all the detergent out, because it may have settled. Pennzoil offsets 100% of the carbon emissions from creating the oil.

[This review was collected as part of a promotion.] I used Pennzoil full synthetic in my generator and noticed how the generator ran more smoothly. The bottle design allows for easy pouring and transferring it out of container. Overall, a quality product.

[This review was collected as part of a promotion.] This motor oil is perfect for the cooler temperatures. It is smooth and thin, it helps our car run great throughout the colder months of the year. I have used this in my wife's midsize SUV and it helped it run smoothly for many miles. I would recommend this!

[This review was collected as part of a promotion.] I have always used Pennzoil in all of my vehicles. It is the only oil that goes into them. The full synthetic is absolutely the best, I will continue to use this going forward. If you're looking for a full synthetic oil, this is it.

[This review was collected as part of a promotion.] This came at a perfect time as my car needed an oil change. I usually go for Pennzoil brand oil because I’ve never had any issues and it is a trustworthy brand. The price is right and is good quality oil.

[This review was collected as part of a promotion.] After so many years of paying the shops to change my oil, I decided to start doing it myself. Pennzoil was my first go to since all my mechanic friends raved about it. I changed the oil as normal and decided to wait and use it for a little bit of time before writing my own review. The quality of the oil is very high. It runs cleaner and I can tell the difference in my vehicles after changing from the oils the shops use. There is an additive that is used in the oil. I did notice that if I did not shake the bottle well enough, there was additive at the bottom (you can see the difference in texture when pouring). I will never take my cars back to the shop again for an oil change and I will always use Pennzoil!

[This review was collected as part of a promotion.] I changed my oil with this Pennzoil Full Synthetic oil and will update this review in two and a half months after I complete another oil change. I put my old oil in an airtight container and will compare the Pennzoil to that once I do my next oil change. I have no other way of knowing how well the Pennzoil works other than to compare it to the brand I regularly use. I’ll be back! My wife says I can’t update reviews, so I will complete another review after my next oil change.

[This review was collected as part of a promotion.] Pennzoil has a variety of products that protect your engine. I’m 43 and have a 2009 Nissan Murano with 120,000 miles on it (review 2021.) Over the past few oil changes, I’ve switched from conventional oil to a synthetic blend and this is my first time using a full synthetic. I made the switch because I’m getting lazy and am lacking the enthusiasm, I once had, for doing an oil change. While most people observe longer drain intervals for full synthetics, Pennzoil’s warranty only applies if you register online and meet certain conditions (such as following the manufacturers’ interval recommendations.) There are a few main variables that impact the duration of the drain interval. These include things like number of starts, what type of filter is being used, climate, driving behavior, etc. My car is outside of the warranty limit, I use good filters and don’t drive aggressively. So, I plan on trying to stretch the oil’s life for the next year (if I can.) There are some benefits to their premium synthetic oils but I’ll probably save that for when I get a newer car. As for the product, there is only one difference in how I do the change… I have to change the distance where the car alerts me about the oil change and increase it from the default 3,000 miles to a longer period.
