No problems so no problems.

[This review was collected as part of a promotion.] I decided to spend the money on full synthetic oil and save money on the labor by doing the oil change myself. I had been taking it to the shop. Now that my son is old enough ,and wants to work on cars, I thought this would be a great start. I can only assume there are no problems since there are no problems. Right? Many miles to go, and then we will do it again.

Works as it should

[This review was collected as part of a promotion.] I used this for an oil change recently. As far as adding this oil it poured well and as far as oil goes it had a good color to it definitely a quality oil. So far seems to be working well. First time I have used pennzoil and I'm a fan.

Does what oil should!

[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.

Super slick!

[This review was collected as part of a promotion.] This full synthetic oil is just like the Review Title says, "Super slick!" My engine runs really smooth with this oil. Obvious benefits of friction reduction of engine components have resulted in a boost in fuel economy. Granted, I don't have a physical/measurement comparison, since I have not taken my engine apart to do so, I'm confident it's doing what it's supposed to do.

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.

Works well in older vehicles.

[This review was collected as part of a promotion.] I decided to use this in my 95 explorer since it has trouble with dry start and I can say this definitely helped out during the heated days. Oil seems to keep the same protection as 5w20 but flows much easier for that old oil pump. I’d definitely recommend this to anyone having a slight lifter tick.

Can't Beat It

[This review was collected as part of a promotion.] I've relied on Pennzoil Synthetic for years in my vehicles, lawn tractor, and utv. I've never had an issue, oil filters stay clean longer, and engines run smooth. It's easy to pour and my funnel filter is always clean. With regular oil changes, both my vehicles and other equipment are well maintained and last longer - my goal.

Make the change to full synthetic!

[This review was collected as part of a promotion.] Pennzoil® Full Synthetic engine oil is a full engineered engine oil that is appropriate for use in new and more established motors. It is detailed to give 40% preferable execution over traditional engine oil1 and permits less oil changes contrasted with customary engine oil. Along these lines, if your vehicle as of now requires full engineered, or in case you're hoping to update from traditional or manufactured mix Pennzoil® Full Synthetic is the correct decision for you.

Perfect for my Equipment

[This review was collected as part of a promotion.] Used this for oil changes in all my equipment, feel totally confident in the Pennzoil brand, and I prefer Synthetic over traditional oil. The case was just the right amount for all my machines with a spare bottle left over.
