An old standby

[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!

works wonderfully

[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.

Trusted brand

[This review was collected as part of a promotion.] Full synthetic is great for my wife's car. Got these to keep in her trunk, she gets paranoid when her oil goes below 15 percent so she can keep this for those days. Until I can get around to doing the oil change.

Excellent motor oil

[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.

Save time and money over the life of the product.

[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.

Keeps my older Mini Cooper running like a champ

[This review was collected as part of a promotion.] After some work to get my 2010 Mini Cooper running well again, the mechanic recommended this synthetic. So far, so good. The engine performance has been maintained, running nice and quietly, and I am not losing oil anymore. I have also been able to go to 6 month oil changes instead of 3 month oil changes, which easily offsets the slightly higher price.

Quality you can trust!

[This review was collected as part of a promotion.] I've been using Pennzoil oil for a very long time. And now that our Honda is getting a bit up there in age and wear, I decided I wanted to transition to synthetic oil. Since I e made the transition, I've noticed a slight increase in fuel efficiency and how the engine runs. I'm excited to see how well it performs as the year goes on, but I know I can always trust Pennzoil, so I'm expecting solid results!
