When do you plan to send your next oil analysis to Blackstone? I'll see if it aligns with my next oil change and we can split the cost, together with other interested parties perhaps.
i'll have shipments going out once every few months to slowest maybe every half a year?
yes (very expensive to USA) cost are shared amongst us senders.
they go for around RM292 these days with rubbish RedLy (PosLaju / Pos Malaysia spin off just for international shipping)
and i typically have between 4-5 samples, so 292/ 5 or 4 is between 58.5 - 73 per sample shipping cost.
so a sample is around RM73 + 30-50 USD to test (and cost is among the main factor deter most people from doing it)
regardless, sampled and sealed oils can be kept for over a year. i've actually gotten one sample kept for around, or over a year in storage because of covic19.
no further degradation observed from the sample with the tested TBN.
key thing is, you have your sample bottle ready before your oil change. please
PM for further details
