Engine oil PENNZOIL or OEM Subaru

I used to only use Mobil-1, now I use Penzzoil. I go with whoever has the best rebate at the time. they are all fine.

I've been using Pennzoil Platinum in my 2010 for a few years. I saw how it was the best oil tested on Project Farm on YouTube. I get it for $27 for a 5-quart jug at Walmart.

For Pennzoil, I always use the Ultra platinum over the standard platinum. It has been tested to have lower friction and higher addictive content.

I have had a much better experience with Pennzoil in Japanese cars. Pennzoil is a bit better.

Don’t use royal purple heard so many bad things about how it’s not a good brand anymore, I swapped to penzoil oil plantinum 5/30 and honestly the car feels a lot smoother and sounds a lil less ticki but still I’d recommend anything other than royal purple

Getting 30mpgs in my ‘14 and been running 5w30 for years, smoother and quieter

No issues with 5w-30. Switched my 21 Crosstrek to it due to the summer months coming. Little dip in mpg but the engine runs smoother.

Either way I have the impression that the engine has a smoother sound and feel now, can this be possibile or it's just a placebo ?

One poster said it right; Amsoil is a Multi Level Marketing program and that's why it's so expensive. Yes it's great oil, however, the Penzoil ULTRA Platinum is high in detergents that keep your engine clean. It's made of natural gas, an industry first, and is so pure and clear you can hardly see it on your dipstick.

I tried pennzoil and didn't like it. The engine developed a soft tick after about 3k miles. Went back to Castrol and the tick hasn't returned.
