Now I warn about the legal English terms engineering interpretation.
1/Mixable with all commercially available motor oils
Does not mean mixes without side effects.
2/Stable even under high thermal and dynamic permanent loads
How stable?
3/No deposits and absolutely compatible with all commonly used filter systems
OK
4/Resists extremely high and low temperatures
How well?
5/- Reduces fuel consumption
OK, but so does thin oil!
6/- Increases engine service life
OK, BUT Impossible to base legal action if not true and no definition of service life included.
7/- Increases smooth operation
OK, but do they mean noise or vibration, definition required
8/- Stable under extreme pressures
How stable?
9/- Chemically inert
When mixed with what?
10/- Higher performance gain due to reduced friction
No definition of performance included.
11/- Does not increase the phosphorous and sulfur content of the motor oil
OK, does not contain Zinc etc.
12/- Tested with catalytic converters and diesel particle filter
No results, so could have been worse? Tested is one interesting word!
LM are good German company and lead the world in some after market additives, BUT, very, very few buyers need to be using their products and would save money finding different type of oil.
All 12 claims made above might well be good, BUT they do not have to be, as they are written in terms approved by legal man who is probably much smarter than average reader.
