I have a Mercedes 2000 E55 AMG which currently uses M1 0W-40 Euro and I'm considering using a 5W-40 for the next oil change because iron in the past two UOA has been slightly higher than normal and the M1 0W-40 has been sheared down to a 30 in about 3K miles for each UOA. Given that, I just want to see what a 5W-40 does.
Here is a list of 5W-40 oils that I'm considering which are all on the MB 229.5 list. Opinions on these would be appreciated.
M1 Formula M
Red Line Professional Series
MB OEM Oil
Liqui Moly Leichtlauf High Tech
