Check the date of manufacturing of the oil on the sticker. Than check the date of manufacuring on the plastic canister. Date on plastic canister is like a clock. 1 to 12 months in clock and an arrow pointed towards the month of production of the can. In the center its written 15 or 14 for 2015 and 2014 respectively. 1 and 5 are seperated by the arrow in the middle.
Now the date of manufacturing on the sticker is usually 2 months or max 3 months ahead compared to date of manufacturing on the canister on the bottom. I usually purchase oils with 2 months difference. If the date on the canister is older than 2 or 3 months. Than remember that canister has been refilled by the local fake oil distributors.
The logic is simple. Two months time to fill the canister is acceptable. But more than 2 months is doubt as we usually throw these are garages where they are collected and refilled which takes alot of time.
Try this method and you guys wont be disappointed.
How i got to know?
I know few of the people working at different fake oil distributors.
