wana ask if any of you request for salary increament after petrol price raised?

my previous job, i need to handle design, meeting client, draft drawing, draft bq, quotation pricing for bq, prepare sample for material, project coordination, site supervision, ordering material to site, arranging worker/ sub-con to site, prepare report, site meeting with client or consultant, arranging payment for sub-con, make claim from client.

now i lost track and dont know how much salary will be reasonable for knowing and doing so many. now i only request& demand based on market value from jobstreet.

now judging from your experience how much is my salary reasonable?
