Use PHP's strtotime function like:

46,971 | Can i use Petrol: **Super 95 E10** in my car? I basically use **Super 98** on my car but the price is very expensive now 1.50 Euro cent. Where as Super 95 E10 is 1.20 Euro cent.
My car manual says i can use 95 RON or higher. Does 95 RON means Super 95 E10?

] | For the main part, just pay attention to the "95". It doesn't matter whether it's E10 (10% ethanol) or regular 95 RON, it will give you the same amount of detonation resistance (in theory). There is a tradeoff with using Super 95 E10 over regular 95 RON fuel, that being energy density. Ethanol has a lower energy densit... | Note that not all cars are specified to use E10. The higher ethanol concentration may be detrimental to seals or other parts of the fuel preparation system.
Advice #1: Check with manufacturer if E10 is compatible
Advice #2: Use Super 95 (without "E10") if available.
