Engine oil VALVOLINE or PENNZOIL

have run penzz plat 5-30 for the entire life of the car almost, recently switched to the high mileage version as im pushing almost 150k miles on it.

i use pennzoil plat every 3k seems to be fine for the past 57k miles

I go every 5k using Pennzoil Platinum 5w-30, though it's just a stock engine/tune and more than half are highway miles

Been using for donkey years and never failed to amaze me. Valvoline till now never seen or encountered with fake ones.

You’ll be fine. I’ve used Valvoline for years over various cars. It’s more just making sure you know what oil to ask for.

The engine itself runs great with the 48K I put on it in the past 2.5 years with biannual oil changes (Pennzoil Ultra Platinum). Averaging 27 MPGs on 91 Octane hwy miles, 24-25 mpg in the city.

I dont know but i do know the valvoline restore and protect oil has helped my 330k mile engine feel like new.

I have a 2007 Explorer with 161,000 miles on it. Just recently switched from Castrol to Valvoline Restore and Protect. I'm not sure why I haven't heard of it sooner, but from what I've heard, it's really good at removing sludge and varnish that forms in high mileage engines.

I'm trying out Valvoline Restore & Protect right now. I only ran oem Idemitsu before but started to have oil consumption issues with that oil the last two winters so I decided to switch.

I know I was using penzoil back when I had a 90 325i, locked my engine up solid, mechanic said it had too much paraffin so yeah it matters personally I only use Mobil 1 synthetics
