Fuel policy
The rule governing how fuel is handled across a rental — most commonly full-to-full (return as received), with full-to-empty and prepaid options used as upsells or convenience products.
The three common fuel policies are full-to-full, full-to-empty (also called prepaid), and same-to-same. Full-to-full is the industry standard and cleanest for the customer: the car leaves full, must be returned full, with a missing-fuel charge plus a refuelling service fee if it isn't. Same-to-same is rarer and lets the renter return at any level matching the pickup level — almost no operator uses it because it requires checking the gauge twice and is prone to dispute.
Full-to-empty / prepaid is the policy where the renter pays for a tank up-front and returns the car empty. It looks like a convenience product but is a margin trap for the customer: any fuel left in the tank at return is forfeited, and refuelling is usually priced at retail-plus, not retail. Some markets have regulated this product because customers consistently overpay; in the UK and EU it is heavily disclosed at the counter.
In renviq the fuel policy is part of the rate plan and is printed on the agreement template along with the missing-fuel rate (per litre) and the refuelling service fee. The inspection capture at handover and handback stores the fuel level so the post-rental charge — if any — has audit-trail backing.
