I have been running this oil in my 2010 MB E350 for the last 3000 miles and I am so impressed with this oil that I created this thread to document it.
For background this car has so far seen 1 OCI of M1 0w40 and 1 OCI of Royal Purple 5w40. While these oils can hold their own, in my observations they don't hold a candle to Red Line 0w40.
Say what you may of Red Line 0w40, being thick, high NOACK or what not this oil delivers when it comes to real world experience. My idle is nice and smooth, there is no cold start clatter that I got with both M1 and RP. I also had a hot idle tick with both M1 and RP that is also absent with the RL 0w40. The engine also revs very buttery smooth, maybe a characteristic of this oil being on the thick side but I sure will take it. I am very big on reducing NVH and believe me you this oil delivers by suppressing noise, idle vibrations and harshness.
The one downside to this oil as some may have already guessed is gas mileage. This is a thick oil with a 40 visc of 81cSt and a 100 visc of 15.1 cSt but more importantly this oil has an HTHS of 4 which is high compared to its competitors. All those numbers translate into one thing, reduced fuel economy. I saw an average drop of 1 mpg but I really am okay with this because one my commute to and from work is only 2 miles each way and secondly I put more importance in engine smoothness which this oil delivers mightily.
Lastly, the biggest negative about this oil as it is with most Red Line oils is pricing. The cheapest I can get this oil right now is for $131.xx for a case of 12 shipped. If you buy single quarts be ready to shell out more money per quart basis. The average price for a quart right now is $10.95. This in itself prices this oil out of many's wish list which is a shame because this is one stud of an oil in Red Line's line-up.
Thanks,
