Engine oil Castrol or PENNZOIL

I use Pennzoil Platinum 5W-30 in my 2011 328ix (N51) I believe that is the recommended viscosity.

I use 5w-30 pennzoil ultra platinum full synthetic with the oem motor craft oil filter

I change my oil every 3k miles

I replaced the plugs, oil/filter and air filter with oem parts when I got it. I\u2019ve been changing the oil at 5k intervals with the recommended Castrol 0w-20.

Frankly, we ran 0W20 for the first 175k miles in our 2017 RAV4. I changed to 5W30 because my Turbocharged Mazda also calls for 5W30.

I run Castrol (bought at Walmart), like my father and his father did before me...

99 Ls400 owner. Pennzoil Ultra Platinum every 5k miles.

I use it in my non deleted CJAA (dumb) but I haven't had any issues (yet) and it doesn't burn oil.

Pennzoil Platinum Euro full synthetic 5W40 on my Abarth. Same weight as written on the engine oil cap and in the user's manual. 5l jugs easily available for $40 CAD plus HST.

I did burn more Castrol than kroon. now i cannot get kroon and changed to Motul which seems to burn faster than kroon.

One time I had the oil bug bite (keera) and I decided to get the best oil. Castrol (I don't remember the number) but it was 340 AED for a gallon. I poured it into the engine and it felt good. That weekend took it for a desert drive and during one of the breaks, the entire oil just leaked out of the main seal. The oil was so good that the engine didn't have the tolerances to hold it back.
