Engine oil VALVOLINE or PENNZOIL

So I went from valvoline max life full synthetic 10w-30 in my k1500 92 gmc sierra sle with the 350 and tow package, flat tapped cam truck, to valvoline restore and protect 5w-30. I was having oil pressure issues, only 188,xxx miles. After switching to R&P, 1500 miles into the oil change, I consistently have above 30psi oil pressure.

Ang nagamit ko palang na brands ay toyota, shell, at valvoline. Walang problema sa 3 na yan. Pero last kong gamit ay valvoline eto yung sakto sa specs sa manual. Mas mararamdaman mo na smooth yung sa makina.

My 03 forester was burning a quart every 1,000 miles when I got it. Switched to restore and protect and it just stopped burning oil. Not even a gradual decrease in the amount it was burning, just completely stopped burning oil all together.

Once my wife's Subaru is out of warranty we will switch it to R&P. I have my Fusion Hybrid running it now. Can't say if I notice a difference cause I replaced spark plugs same time so I'd course it's smoother starting/stopping.

I just switched the my oil to Valvoline Restore and Protect. It reduces the burning tremendously to normal burn rate after 1000 miles monitored. Good stuff.

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

If you have ever rebuilt an engine that used Pennzoil, you would never use it again. The top of the head will be covered in carbon.
