Well ive been using it from the word go on my new engine.
Ive bought 2 boxes just in case they stop supply. Its not repacked at all ( backyard Toyota dealer ). Specified VVTi engine oil 10w30 and im happy, mind you my engine has 5,700 kms and ive changed the oil already 5 times
BTW i got a box of filters free , mind you i bought a lot. So an oil change which i like doing is only $15 for me
