Engine oil PENNZOIL or OEM FORD

I use Pennzoil in my cars because it won project farm's oil showdown.

Pennzoil Platinum Euro is one of the best oils available as far as NOACK is concerned. It meets most if not all European car manufacturers specs and is the factory fill in Fiat/Alfa engines.

Tie between Royal Purple or Pennzoil, choice usually based on availability or sales. I might slightly favor Pennzoil due to its connection with Shell as I exclusively use Shell 93 fuel for the additives.

My engine is happy with Pennzoil Platinum. No leaks and minimal oil consumption.

While any oil can work for your car, the current best option in the market is Pennzoil Ultra.

I combine that with Pennzoil Platinum as there’s almost always a rebate for it. I paid $12 a jug after rebates for my last batch.

I personally like using pennzoil euro platinum 5w-40 in my Mk7.

I've run Pennzoil Ultra in 5W-30 for the past 4 years and never had a problem.

Some 5w-40 can be quite thick in cold. The 0w-30 here is German Syntec, and trust me it's the same visc curve as 0w-40. As you see, 5w-40 is 3-4x thicker in cold than jug 5w-30

I use Pennzoil Ultra Platinum 0W-20, and follow a 5K miles/6 months time change schedule. (It’s twice as often as is recommended but that’s just my personal preference on how often I change it, not indicative of oil quality or use parameters.)
