Works great in my car

[This review was collected as part of a promotion.] I do the oil changes for both vehicles in my household. I got this Pennzoil Full Synthetic oil for my Mini Cooper. It’s a great oil. My car has been running great since I changed the oil and put this new oil in it. This oil is easy to work with and I’ll definitely use it again when it’s time to change my car’s oil again.

Great product

[This review was collected as part of a promotion.] I regard myself as someone who is not a rookie/novice do it yourself but not a expert. I'm always learning things and working on my own cars is 1 thing I love to do. I've used this brand in the past when going to a shop but now I do it myself and it has never gave me any problems!

Pennzoil is the only oil you should use

[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!

Great quality.

[This review was collected as part of a promotion.] After so many years of paying the shops to change my oil, I decided to start doing it myself. Pennzoil was my first go to since all my mechanic friends raved about it. I changed the oil as normal and decided to wait and use it for a little bit of time before writing my own review. The quality of the oil is very high. It runs cleaner and I can tell the difference in my vehicles after changing from the oils the shops use. There is an additive that is used in the oil. I did notice that if I did not shake the bottle well enough, there was additive at the bottom (you can see the difference in texture when pouring). I will never take my cars back to the shop again for an oil change and I will always use Pennzoil!

My go to

[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.

Excellent product

[This review was collected as part of a promotion.] I usually take my F-150 in to have the oil changed but decided to do it myself. This is some quality motor oil. With the Pennzoil name you know it will be good. I have never tried full synthetic in my truck but with it's higher mileage I think this will work well. I have used Pennzoil products for years in my boats so I have no reason to believe this will be anything but excellent.

Slimy motor oil.

This motor oil is in fact quite oily. I haven’t been inside my engine lately, but I have to assume that it’s covered in this motor oil. I poured it in. So it’s gotta be in there. Gotta be real slimy in there. Four stars cause it comes in 1 qt jugs. That’s a lot of twisting caps and that’s annoying. Just give me a big jug so I only gotta do the twisty dance once.

Almost got order correct

Ordered 4 cases of synthetic and they shipped 3 cases of synthetic and one regular motor oil. Had to return that case. Oh well better luck next time.

Well known brand

[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!
