Thanks all for the input. I will consider all of the info when I do the next change in about 2 months or so. Like I said previously went with the M1 15/50 this go around, and at the price I dont think I will be draining it to change it out now....This forum is great especially for me who has only had his Diesel Benz for about a month...

Thanks again!
