SLK/R170: Amsoil
I will not name the company but I will say the car is very yellow.
This stuff is the best and that coming from testing it to the extream.
I ran the oil over 30.000 miles with out changing it in a 97 f-150 towing heavy loads and it did the job with out any failure. I just got my SLK 230 after selling my Stealth which I drove at 130 mph on a regular basis and the car had 230K on it maintained but high miles. I ran it on Amsoil and it was a bat out of hell. So at oil change the Mobil 1 the guy was running goes by by.



I have used it for years now in all kinds of vehicles.
