Just would like some opinions on what I did. I changed my oil in my 08 MB v6 diesel. It uses 8 qts and I usually put in 7.5. I put in 4 qts of Mobil 1 TBT and reached for the 2nd jug, picked up the wrong jug and put in about 2.5 qts of Mobil 1 0-40. Caught myself and then put in 2 more qts of of TBT. I'm leaving on a 10 day trip of over 2k miles. Thinking it will be ok and I'll just leave it in there. Before the argument starts, I have been using a mid saps oil in it and decided to switch to TDT because I have seen some great uoa's on that oil in these vehicles. I'm going to .8 saps to 1. I know the 0-40 is over 1. It will be mostly highways miles. What say the bitogers .
