VAT after gst

Petrol is not covered under GST, So VAT return I think.

Petrol is exempt from GST

Oil comes under GST.

But petrol and diesel are not comes under GST

GST is not applicable on Petro Products including natural gases, diesel and petrol.
but on Items such as Lubricants and distilled water GST is applicable.
As we know generally every petrol pump is selling Lubricants ( covered under GST ) along with Petroleum Products ( Exempt under GST).
As they are selling Taxable Products under GST , therefore GST Registration is required for them.

All petro products are exempt
