Pennzoil Ultra Platinum Full Synthetic 5W-30 Motor Oil, 5 Quart (3 Pack)

This full synthetic oil keeps the engine running incredibly smooth and noticeably quieter, especially during cold morning startups. The advanced formula cleans out sludge effectively and maintains its viscosity perfectly even under heavy driving conditions or extended heat. It’s an absolute staple for anyone looking to maximize engine longevity and keep performance top-notch.

Excellent full synthetic oil from Pennzoil. I’ve used Pennzoil for many years as it made my cars run quiet and I never did have any engine issues. The Ultra Platinum version is the top of the line in the Pennzoil oil products. It costs a little more but the benefits are well worth it.

Best oil next to amsoil. Been using it in my 19 gmc terrain since I bought the car new.

I used this synthetic oil for a snowblower oil change, and it handled the job exactly the way you want in cold weather. The pour is smooth even in low temps, which makes it easy to get an accurate fill without fighting thick, sluggish oil. Once in the engine, it noticeably improved cold starts and kept the Snow King running steady under load. The formulation feels cleaner than typical budget synthetics, and the engine tone stayed consistent after a few runs, which tells me it’s doing its job with good film strength. For the price, the durability and cold‑weather reliability make this synthetic oil a solid value, especially if you’re maintaining small engines that sit for long stretches between uses

I could not believe it. This oil, despite costing more money than conventional oil, may be saving me some money. Others have said it can improve your MPG, and I thought that was crazy. I bought the oil because I have a high mileage Toyota 4Runner that I care a lot about, so I wanted the best for it. I also wanted the extra cleaning powers of synthetic, and this synthetic rated second to Amsoil on project farm. The low friction properties must be what does it, or I don't know what, but my MPG has gone from 17.5 average to 20 average. And I had a lot of highway miles before the change contributing to that 17.5 calculation, the 20.0 MPG has been produced mostly on a mix of city and highway driving. When I go on a long trip and rack up mega highway miles it may go higher! And yet Toyota publishes a max highway mileage of 19MPG for my 4L V6, and I'm doing better than that! An improvement from 17.5MPG to 20MPG over a 6000 mile change interval could save me about 53 gallons of gas in that interval, or over $100!!! (Hypothetically) I'm just happy my engine seems to like the oil better, although it DID NOT quiet the ticking noise from my engine, so I wouldn't buy this expecting it to cure engine noises either. I don't blame the oil for the noise, I think it's my valve clearance. I would say don't buy this oil with the intent to increase your MPG. Buy it because it's a great synthetic oil with extra cleaning powers and a longer change interval, although being the car enthusiasts we are I still won't run it longer than about 6k miles. However, be pleasantly surprised if your MPG magically goes up. This might happen more often with old engines like mine, that are needing some extra cleaning power. I don't know if it would change the MPG of a new engine as much. Per the other reviewers comments I shook the bottles before pouring it in, I guess the additive package can separate? I shook them all first so I never saw stuff in the bottom once they were empty. You want that stuff in there, according to the manufacturer. It should stay mixed up once it's in your system anyway, constantly being pumped and churned.

I watch project farm. He did various tests with motor oil and this was second to Amsoil, but Amsoil is too expensive. This is a great price for how well it performed. The Ultra Platinum is much better than just the Platinum but most local stores don't sell the Ultra Platinum sadly.

Great oil at a fair price however the price keeps creeping up like everything else

What more can you ask for, this is recommended by the manufacture and it always gets high marks on reviews. It provides great protection, quality oil and seems to have made the engine a bit more quiet. It is top rated for a reason and usually hard to find locally.
