Review: Pennzoil protection for all seasons. - This is my Holy Grail oil for my IS300. This is a great product at a better price then most and I just love how it works with my car. I don't expect any horsepower gains but it makes the engine smoother and revs much better than normal conventional oils. I've heard Pennzoil has a lot of experience in oil making and I can see that with this oil.
Review: Pennzoil Ultra 5W-30 Too Expensive - This product is way overpriced. I can get it at WallMart for 30% cheeper!! The only reason I bought it from desertcart is I was away from a WallMart for about a week.

### ⭐ Pennzoil Ultra 5W-30 Too Expensive

### ⭐⭐⭐⭐ Good oil, unfortunately for my application it's not up ...
*by T***C on July 4, 2017*

Good oil, unfortunately for my application it's not up to the task. I got 3 - 5 qt jugs when they were only $28 each earlier this year - with the Pennzoil rebate I was able to get the jugs for under $20 which was a steal. Now that they have changed the appearance of the bottles to the yellow ones the price has jumped up significantly. In the 5w-30 flavor 6 quarts is $54 dollars now which is equal to the the price of a few boutique oils. This is being used in a 17 WRX STI which is notorious for being hard on oil in addition to being a oil burner; the last oil analysis had a TBN of 5.2 @ 4,100 miles which is great; but the oil sheared down to a 20 weight oil (cSt @ 100 c = 8.94) also once I've reached 3,000 miles on a given oil change with this oil I've burned .5 qt's. Due to price increase it will give me a reason to switch to a more stout oil like Motul X-clean 5w-30 FE - for the increase of roughly $15 I'll be willing to pay to make the switch.
