[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.

[This review was collected as part of a promotion.] This stuff does just what I need. The bottles are well packaged to prevent spillage, easy to pour from, and I have every reason to believe that the oil itself is of top quality. I can’t really say for sure as testing oil would take a very long time, but the car runs great and I have not seen any sort of accelerated oil leakage or burning. Would buy again!

[This review was collected as part of a promotion.] Full Synthetic by Pennzoil is nice. Very high quality and versatile motor oil product that can be used to service many kinds of vehicles. Easy to use and keeps vehicles running smoothly. I would highly recommend this motor oil from Pennzoil.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic Motor Oil is good quality motor oil that helps keep my engine running smooth. It is better than conventional oil and will allow for fewer oil changes in the future so that is a plus.

[This review was collected as part of a promotion.] I always get Pennzoil for my car. I have to get the full synthetic since my car is foreign. Got this to do my own oil change and my car runs great. My car is getting higher in miles so will have to go with higher mileage oil next time.

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic Oil is high quality and long lasting. It has the highest protection for my internal engine parts and will be a constant in the my oil changes moving forward. It has made my engine and car run smoothly which is fantastic.

[This review was collected as part of a promotion.] Pennzoil is the best oil out there. It has yet to let me down and everytime I've tried a different oil, whatever machine I'm using the other oil on doesn't seem to last as long. Pennzoil guy for life!

[This review was collected as part of a promotion.] I received this a while ago and just did my oil change yesterday. Oil was clean and went in steady. I applied the new filter and only time will tell how my engine runs. So far it seems do be running great!

[This review was collected as part of a promotion.] Have been running this in my 2014 Wrangler (145k+ miles) since we reached 75k+ and couldn't be happier. Long lifespan and has been great in preventing other engine issues and usually get at least 4,000 miles per oil change
