I hope and I think it will be the case.
QSUD (which is a good oil imo) starts at 11.60 cst @100c and ended up at 7.81 cst @100c after 4500 miles.
A lot of people on this board claims it is fuel dilution, but it would require a lot of fuel to bring it down that much (BS reports 0.8%) and I highly doubt it is the case.
Next sample of RMV goes to OAI to clear this up.
OAI may only provide a fuel estimate if viscosity looks ok. Just put a note that you're also requesting an actual fuel reading by GC.
Will do.
Is there an extra cost?
No.
