I'm also going to change the PCV next OCI. I think it's safe to say the oil is not the contributing factor to the oil burning and it's probably more likely the rings. I can't believe how badly the TBN took a beating though. TBH, I was more interested in the fuel dilution and viscosity (pointing to a lower flash point causing the burn off). In my experience the Motul has proven to be a very high detergency oil, and the maintenance on this particular vehicle has been far from stellar to say the least. That was my first train of thought when I saw these results. AFAIK boron is "sacrificial", and Mg is definitely from old fill and old oil diluted the rest of the results. Plus, if there is sludge/buildup from all the burn off, the Motul could be freeing up those deposits back into solution. Sure, since about 15-20% is left over when you drain the sump. Even the TBN seems insanely low, all to the point they think I labelled the oil wrong, which I'm sure I didn't and I know they didn't top it off with anything else.Īny suggestions? Is it possible these discrepancies can be from remnants of the old oil? I sent a VOA for this oil in and the results don't line up at all with this UOA. Iron seems to be within specs, silver came back a little off (bearings?) they say possible solder (not sure if it has a oil cooler.) fuel dilution is not an issue, however I'm concerned with the oil specs. I got the results back today, and I'm quite perplexed.
#Motul xclean fe full#
This time I asked for a full gas chromotography test.
So u pulled a sample through the dip stick and sent it off for analysis. The reminder came on 3697kms and it was already 1.25L low. This time I filled it with the Motul xclean efe 5w-30 I use on basically everything I service and I set the OCI to 3 months or 5k.
They came back to me about 8k next time and same results low oil level. I BELIEVE I put castrol or whatever was on sale when I changed it with a fram tough guard filter (I know, don't bother I won't use it again.). Sump takes 5.5, that run they put over 10,000kms on and didn't check the oil. The fist one I did, didn't check the dip stick but when drained the old oil into the jug, it only had about 2L of oil in it. He hasn't been great with the oil changes on this thing before I started taking care of it. So I have a friend I service all his cars for him.
