PennzoilPlatinum Full Synthetic 0W-20 Motor Oil, 5 Quart

Quality product oil

Very good.

I've been using the Ultra Platinum 10W-30 for several years on my 2004 Hyundai Tiburon i4 and my wife's 2007 Hyundai Tiburon V6, and both engines have been running very well - smooth, quiet, and fuel efficient. When I drain out the old oil after about 10,000 miles or one year of driving, the oil still looks good and clean, having gone from light amber brown to dark amber brown but not dark brown or black.I believe it's totally worth the extra coin to get the Ultra Platinum to get the most out of a car's engine. 5 Stars.

Pennzoil base stock oil is derived from natural gas and oil analysis of the new, unused oil shows that it's extremely pure. As you know, dirty oil is the enemy of engine longevity, so starting out with the purest oil possible is a good thing! Used oil analysis also shows that this oil resists breakdown quite well, well within the acceptable protection range in terms of viscosity and staying power of the additive package. Best of all, I'm getting a high quality oil at consistently low price. Pennzoil Platinum does a great job of protecting my engine at a price that is easy on the budget. Unless the price drastically changes to the upside, I don't see any reason to switch to a competing brand. However, if you drive a high HP sports car, the Ultra Platinum version has a somewhat better additive package for more extreme conditions.

I use Pennzoil for many years for all my cars. The cars run smooth. It always in stock and easy to purchase from Amazon or Walmart for best price. Autozone and oreilly always have it but 20%+higher prices . I usually change oil every 5k miles even it says can go up to 10k miles. All my cars running strong without any issues. Get the 10k oil filter with the oil, your car will run great

This is very good oil for a lot less money than my other choice (Amsoil). However, it's frequently out of stock on Amazon and they do a very lazy (or at least inconsistent) job of shipping it.It rarely has the "gripper" sticker that keeps the cap tight. Usually no secondary container (bag). It's generally just tossed in a box and sent out. Given that this is technically a hazmat, I don't know how Amazon gets away with it.

I enjoy watching automotive product comparisons on YT. Review after review validates the superiority of Pennzoil full synthetic motor oils over the competition. Whether in terms of cold flow rates, lubricity, friction protection, resistance to heat breakdown, or the extent of additive levels, Pennzoil synthetics almost always top out the list (save for the Am... line which, while being the "best of the best", costs nearly triple everything else). I typically watch for a price reduction or rebate and then buy a case or two on Amazon. It is a rare day that anyone else even comes close to Amazon's prices on Pennzoil synthetics, and nothing beats having the jugs show up the next day via Amazon Prime. Thank you Amazon! P.S. One comparison review actually rated the Pennzoil "Platinum" product higher than their more expensive Pennzoil "Ultra Platinum" flagship oil.

First, a disclaimer: if you ask 10,000 car nuts what their favorite oil is, you'll get 10,000 answers and 10,000 reasons why. So, YMMV.I originally tried this oil on a Subaru Forester, and it made the engine considerably quieter to me, but even my mom asked why the engine was suddenly not making so much noise. So it's not just me! After success on that car, I was a fan of Pennzoil Platinum (here on out referred to as PP) so I decided to go with it on my Mustang.I had changed the factory fill at 3000 miles with Ford Motorcraft 5w20, which is semi-synthetic (a blend of conventional and synthetic). Now at 8000 miles, I changed it with PP 5w20.A note to fellow Coyote owners: the engine has the typical coyote 2200 rpm rattle as well as the tick, and no, neither of them went away after using this oil. Watch videos online regarding those issues and you will go down a several-month rabbit-hole and end up with more questions than answers. From what I've found, the rattle is piston slap, which is normal and actually common in racecars. The tick is axial movement of the bottom end of the con-rod against the crank, but both parts are hardened steel and no damage will happen, especially with an oil film there. Both of these noises are caused by looser tolerances, which means NVH, but also lots of power. I have found rebuilding a small engine with new bearings, honed cylinders, and new rings, that it ends up making less power. A loose engine is faster (unless there is blowby of course). My point: don't worry unless you find metal in the oil, or it blows up. Enjoy your car.Anyway, I digress. The rattle is a little quieter when cold, possibly indicating that this has more of a 'cushioning effect' of the piston skirts at lower temperatures than the Motorcraft oil. Typical of synthetic oils -- they are better at cold temps.One other thing I noticed was that the smell of Motorcraft oil and the smell of Castrol's 5w20 Fluid Titanium is the same. I don't know if this is the additive package or the base stock, but this Pennzoil Platinum does not smell the same as those two. Not sure what that means, just an observation.Anyway, this seems like good oil. I am not worried about my engine blowing up. I would not be worried tracking my car with this oil. Buy it if it is cheaper than Castrol or Motorcraft.
