tusabes They are both high quality oils and either will be fine
I know people take oil choice as a religion but it’s not really that important which manufacturer you choose. Any band brand oil, changed regularly and kept full will protect your car just fine

All oil problems come from failing to check level and starvation. Or infrequent changes . That’s it.

The brand you use doesn’t matter and for most of us in average climates the oil weight doesn’t matter either .

That looks good!! I have actually heard the same.

bkdc The most important thing is to change the oil and filter frequently. The oil doesn't matter as much as long as it's a decent oil that meets your manufacturer's specs. I just pointed out Castrol because it is superior to and priced lower than the very popular Mobil 1 0W-40.

The stoutest oil I've found is Redline 5W-40 although it is not MB approved. The HTHS of 4.4 is insane and this oil is perfectly safe to use. I'm just not willing to pay three times the price for oil when the Castrol is perfectly adequate.

I used to use Liqui Moly Leichtlauf High Tech 5w-40 but the Castrol Edge 0W-40 is the best bang for the buck out there, and it's hard to beat for the price.
Great thank you!!

And there is absolutely no reason to buy Mobil 1 0w-40 euro synthetic (Group III GTL gas-to-liquid) oil (not true synthetic by European standards) when you can buy Castrol EDGE 0w-40 (Group IV PAO poly-alpha-olefin, true synthetic) oil at 5 quarts for 22.48 on Walmart or at times on Amazon with free shipping. The Castrol is superior in every way and also meets MB certification. Stock up.

Indyvol I live in the midwest, and have used nothing but Mobil 0W40 in both our cars. No issues of any kind in 8+ years.
