Re: Is supermarket fuel good enough?
Article from Which from last year says not much difference between supermarket and brand petrol.

Personally, I fill up at Costco (Skoda Kodiaq 1.5SE)

Quote:
There are two aspects of fuel quality which depend on the fuel brand and the individual retailer: deposit control additives and forecourt maintenance.
Deposit control additives:
Every grade of Kirkland Signature™ Fuel contains deposit control additive that keeps your engine protected and running like new.
Variations in deposit control additive formulations are the main difference between brands of fuel. Kirkland Signature™ Fuels have been proven to clean deposits and restore dirty engine components to like-new performance.
Station Maintenance:
Good station operation and maintenance means the fuel is filtered and that contaminants, such as sediment and water, do not find their way into our members' vehicles. Costco fuel stations are well-maintained by our capable attendants so you may be confident that the fuel going into your car is clean.
Costco uses fuel filters in the petrol pumps to catch particles or debris larger than 10 microns in diameter. For comparison, the average human hair is seventy microns thick.
Costco uses ethanol-compatible filters designed to catch sediment, water, or phase-separated ethanol and water mixtures.
Costco's electronic sensors continuously monitor our underground storage tanks for water.
