[This review was collected as part of a promotion.] It's a great full synthetic oil from a brand you can trust. So, the results are perfect, as expected! Great packaging for the shipping, impressive results! This oil will keep my car's engine running nice and smooth for the years to come.

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic is a great product for what I do. In fact anything with the name Pennzoil on it is worth it. Keeps my engine going for a long time, great product and long lasting. Highly recommend.

[This review was collected as part of a promotion.] I love Pennzoil. I like the fact that it is made well without contaminants in the oil like regular base stock mineral oil. Works great and all the applications that I used it in for my jeep wrangler and suabru. I've found that cars I've used other oil on have had engine troubles, while I can prove a correlation I do believe this to be related.

[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 was sent a case of six bottles of Penzoil Full Synthetic oil to try. First off I was shocked that I ended up getting a case of this oil. This oil works great for my car. Sometimes I tend to buy cheaper oil and I think that that oil does not work as well. Using Penzoil I know that it is better for my car and lasts longer. Having six separate bottles is more convenient than having to store a big bottle. This oil has just the right amount of thickness, meaning its not watery like some other brands.

[This review was collected as part of a promotion.] Pennzoil full synthetic oil is awesome!! My car responded very well to the Pennzoil full synthetic on this recent oil change. I could tell a big difference in how she sounds and runs since changing the oil. This has to be one of the best synthetic blends on the market. My car has never responded so well in all my oil changes. Improved gas mileage for one is a big plus and a smoother ride all together. Many people don't realize that the quality of oil is important and Pennzoil outshines the rest. I am definitely using Pennzoil full synthetic again on my next oil change.

[This review was collected as part of a promotion.] When it comes to adding life to your engine the one single thing you can do is keep the oil changed! Oil is the life of your engine regardless if it’s your automobile or your lawnmower. This Pennzoil full synthetic is a great oil and is 100% synthetic that provides better fuel economy and great wear protection. I highly recommend this oil.

[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.] I have never tried the synthetic oil previous to this. I heard rumors to stay away from synthetics in the past. My son in law is a farmer,( they use a lot ) and he is the one that convinced me to try it. I have it in my riding mower and truck. I guess I had some bad information.

[This review was collected as part of a promotion.] I got this Pennzoil full synthetic to use in my f150. I usually take it to the dealer and they use a synthetic blend. Well my warranty is up so I figured I'll start changing my own oil and at the same time this will give me a chance to keep an eye on what's going on under the truck. (leaks and such) I've used pennzoil in the past on other vehicles with good results so this was pretty much a no brainer. Time will tell but with a company that's been around this long they must be doing something right!
