Pennzoil Platinum Full Synthetic 5W-30 Motor Oil, 5 Quart

Great oil, lasts as long as it states, so go as many miles as you want, I never go over 8k but it would last longer saving you a ton if you do the changes yourself and all natural vs other brands which are not. High performance, I would go with Royal Purple, cheap product for every day use.

Great price and best option for your Subarus lube. I’ll run this over any other option! Every 3,500 miles

Pennzoil Platinum is an excellent and premium quality oil. Use it in my 2006 Solara V6 Sport and 2011 SantaFe every 5k or 8-9 months.

Pennzoil Platinum Full Synthetic 5W-30 is a great motor oil that gets the job done. It performs well, keeps the engine running smoothly, and comes at a reasonable price. No complaints—definitely a solid choice for anyone looking for quality oil.

I have used Pennzoil in my 2003 Trail Blazer for its entire life, at about 150k switched to the synthetic. Change oil every 5k which is usually around 50% life. The TB has no leaks and burns no oil. I attribute this to regular maintenance and the quality of Pennzoil.

It's penns oil. It was about four dollars cheaper delivered than buying it down at walmart

Best oil for my 2011 Subaru WRX. been mainly using this oil since 2017 and car still running strong.

A family member owns a car that has a turbocharged, direct injection engine and I'm the guy that services it.This type of engine tends to suffer from LSPI (low speed pre-ignition) that can be quite damaging in the long term. I'm not sure what the mechanism that causes LSPI is, but I do know that calcium content in the oil detergent package is one of the contributing factors.To combat this, manufacturers started recommending oils with different detergent packages. Oil chemistry is a very complex subject and I only understand a tiny bit of it, but with more DI engines being produced, both oil and car manufacturers have revised their recommendations for oil.For my old clunkers I buy whatever oil is cheapest, usually a bargain synthetic or synthetic blend from either the big blue store or from the discount warehouse. For the car with the turbo DI engine, however, I look for something that is API SN+ or SP rated.These ratings address, in part, the issue of LSPI that affects DI engines. I believe that oils rated to ILSAC GF6 do as well, and most of the oils I've run into carry both (and many more) of these certifications.Does it work? I have to assume that it does. I've never noticed any LSPI in the car that I service, but you can't always hear it and I haven't done any further investigating. The car runs fine (better than fine, actually-- it HAULS). Oil pressure is fine and I never hear any startup rattle or other odd noises.I HAVE noticed that this Pennzoil Platinum shear-thins a lot less than some other oils in this application. The owner of the car ended up doing an oil change with some other 5W-30 synthetic recently, and after 4500 miles that oil came out quite thin and considerably more runny. Back to Pennzoil Platinum and a Wix filter we go.The cheapest synthetic oil I can find in my area is usually around $17-18 for a 5-quart jug. This Pennzoil is $23. The extra few dollars a couple of times a year buys a LOT of peace of mind.
