I'm pretty sure we have extensive discussions about the positives and negatives of each company. It's fine knowing the back story of a company and the risks that come with it. It's up to you to decide where you want to cut corners. And if you ask me, in my case (daily driver cars), I definitely do not require my oil to be of the absolute top grade per say based on my engine and usage of it. A medium to high "quality" oil is already surpassing what I require.
In the past years, I have been using over 6x 20 liter cans of Mannol MN7701-20 (5W30 API-SP) in BMW M54, N55 and B58 engines.
The M54's are frequently used on high speed autobahn. The N55 is an average daily and the B58 is a 550HP beast which usually runs on E85 fuel and enjoys autobahn runs and towing trailers a 1000km to Southern France.
I run all of them on Manoll MN7701-20 with an interval of ~20k km on the M54's and N55, and ~15k km on the B58.
While I am no oil expert at all and I have zero scientific proof to back this up, it is not possible to deny that this oil has worked great for me so far. All these engine are used at above average loads and have done so for a combined distance of over 300.000 km.
I have never noticed any difference in smell, color or viscosity between the cans.
So yeah, I really can't take statements like "I wouldn't run this in my mower" seriously. If you don't want to buy from this company from a moral of principal standpoint, that's up to you. Free country. However, How sure are you that we can't find any dirt on your favourite company?
