[This review was collected as part of a promotion.] I got this pennzoil full synthetic motor oil to try out in my 05 pontiac g6 with 75000 miles, and must say that so far has been a great motor oil. Put about 3500 miles on it since changing the oil and still is pretty clean on the dipstick. Think I may be changing oil brands.

[This review was collected as part of a promotion.] I use this for a multitude of things that uses this oil. It works perfectly in my car. I don't think I have ever had my car run so well before. It seems like it runs smoothly as well. I went on a few trips already out of state and there hasn't been an issue.

[This review was collected as part of a promotion.] Ive used Penz for years in my cars. I always appreciate the quality of their product. Especially as they have introduced synthetic. I've gotten out of the habit of changing oil, but my son and I worked on changing his together. A great product!

[This review was collected as part of a promotion.] This Pennzoil Synthetic oil keeps my baby running good and she's happy so I'm happy. I got a couple 1 quart bottle's and i poured them all in perfectly as i always do. I check ever quart by smelling it and i also give it a little taste and Pennzoil has a great taste so that's how i know it's good. lol

[This review was collected as part of a promotion.] I got this oil for my car because I thought I’d try using synthetic oil and see if it works better than conventional oil. So far, I’m better gas mileage, the engine seems to run a little smoother and I can go twice as far between oil changes. It’s a win win win.

[This review was collected as part of a promotion.] What can you say about Pennzoil and their great products, They are simply the best! This is my first time using the Pennzoil Full Synthetic and my Nissan Maxima loved it. I ran it for the full 5,000 miles and when I changed it out, the oil looked as good as the day I put it in. Definitely my new favorite pick for oil in my cars. Highly recommend to all!

[This review was collected as part of a promotion.] Ever since changing to this oil in my minivan ive noticed a major change in the performance of my van. It has improved my gas mileage and made my van run more smoothly. Before this oil my van would have a small miss fire but after this oil ive had no problems at all with it. Over all this has been the best oil ive ever personally used and I won't go back to my old stuff.

[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.] Penzoil is a premium brand for your car. It Cleaner pistons , better fuel economy, protects horsepower, unsurpassed wear protection, excellent performance in extreme temperatures Its was very easy to use in my car I did not get the big 5 gallon jug but six regular sized bottles. This is great for my car that does not have high mileage.
