Engine oil Castrol or PENNZOIL

I always go for Castrol Edge. Always have, always will

On my ( 2006 Mazda 3s 2.3l auto sedan 350k miles ) I don't burn a single drop of oil and the car runs great even the transmission and I've been sticking to 5W20 Castrol edge extended performance all year

As long as you get name brand oil at the weight your owner manual says you'll be good, I run penzoil in mine and she seems pretty happy with it

Finally ended up with Penzoil Plat. Can't tell a difference at all when the oil is fresh. Also engine never burned oil on Penz.

My car is at \~7600 miles. I changed the oil at 500, 5000 and then I'll change it again at 10,000. I used Castrol Edge 5w30 for the first two and I'll use it for the third oil change as well. I'm going to send a sample of the oil at the 10k change to Blackstone Labs to see how the Castrol is doing.

I have been running Pennzoil platinum euro in my 16 GTI its entire life and its now at 125,000km. I ran the same oil in my 2007 GTI before I sold it up until 190,000km. Never had a single problem, neither cars burned any oil.

I would recommend the Castro Edge PROFESSIONAL 0w-20. Been using it in my wife’s LR4 since we got it and it was the consensus on best oil when I first did my research. It’s a little pricey but we’ve had zero engine issues with this.

Pennzoil Platinum Euro 5W-40. It’s LL01 approved

I use Castrol EDGE Fully synthetic oil in my 2013 Mazda 3 skyactiv. It does burn a little but I did not have any issues.

Yes, Castrol is crapola, so is Kendall. Valvoline is the best.
