I am the proud owner of an ancient 525 Bmw tds. (250tkm) 1992
After the oil change with the konventinellen 5W-30, he always has something nailed. (Especially in winter)
The soot was impressive. (Cold start) Likewise, the oil consumption. Ca 0,2ltr-1000km
Then have the soup exchanged the 10W-40 and LM Motorprotekt as an additive and was really surprised.
Apart from the engine during cold starts just as calm and quiet as running in the hot state of the fuel consumption has dropped noticeably. Although the oil consumption is still there, but much less than before.
The car pulls better and burns cleaner. No Rußfahne at full load. (Cold start) No neighbors angry close the window.
Bin beforehand with 80ltr Diesel approx 750-800km far come-cruise control and sparsam- and am now at 950-1000km.
Cons so far:
The effect wears off after ca.5000km something. I always fill some oil to the previously mixed with the additive did. ca 1-1 / 2 ltr. The effect is then again noticeable.
Before joining I had before villages go only by the gas to slow the car, now I have to slow down ...
All in all, one thing that is worth the money.
From me only recommended.
