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.
