Good morning BITOG faithful,
For my very patriotic 1776th post I present to you a UOA for the longest run yet on our 2018 Lexus GS350. This run ended with 9822 vehicle miles and 4096 on the oil, the sample was taken through the dipstick right before taking the car in to Lexus for it's first free oil change. Oil in use was Valvoline Syn Power 5w40 MST 6.5 quarts with a half bottle of Redline Break In additive to boost the add pack a little. Why 5w40 in an engine that specs 0w20? Well for starters it's an acceptable grade in Australia, and I had it laying around from a clearance sale 3 years ago. Filter was Genuine Toyota this go round so as not to raise any suspicions at the dealership when they pulled out a Fram TG9972. Current fill is TGMO (bulk) from the dealership and a Toyota oil filter. This fill will get run until just before I leave on deployment and I will change it prior to leaving to have Lauren all set to not need any maintenance while I'm gone. It will probably have ~6,000 miles on it when it gets changed out. Engine seems to be breaking in nicely and the early short changes leading up to this run give us a little better look with the early break in junk flushed out. Iron is up 1ppm despite the run being almost 2x as long, which is good to see. Viscosity is a touch low, but since factory fill is a 0w20 it surely didn't hurt anything. No idea what oil I will use next for the upcoming oil change, have lots to choose from, but will save my M1 AP 5w20 for a full 10k run later.
Enjoy!
