Fuel Doctor Cleaner/Conditioner 1ltr $35.69 + Shipping / Pickup @ Supercheap Auto

Normally $41.99, I find this stuff to be pretty good, though maybe only really worth buying in special. Good for petrol or diesel is detergent based, no hydrocarbons.

    Lots of good reviews. May be worth a shot on older cars with bad km's/tank efficiency!

  • How does this compare to the Rislone High-Performance Injector Cleaner?

    • Rislone is hydrocarbon based, basicly kero as I understand it.

      I’m not in a position to say why one approach is better than another except to observe that higher end fuel additives like in BP Ultimate are detergent based.

      Plus Rislone’s made in the US.

      If you use top shelf 98 then it’s probably a waste of time but for older cars and those who use 91/E10 or even 95 it’s worth a look.

  • "Fuel Doctor is suitable to use in all petrol and diesel engines and will stabilise and extend fuel life for up to 24 months" so using this would be better than adding Sta-Bil for non frequently used cars or cars in storage?

      I’d suggest it’s an alternative as distinct from any marked improvement but I guess Fuel Doctor claim double the timeframe. Stabilising is one of the purposes of the product.

      The company started out cleaning underground fuel tanks, they have info on marine applications as well as stabilising and there’s a video demonstrating moisture dispersal - https://fueldoctors.com.au/product/

      at $35/ltr , just fuel up at servo when you want to drive

      • Sta-bil’s about $100 a litre, plus it’s to ensure fuel left in the tank is stable for vehicles in long term storage.

        That's not the point. If you have a very infrequently driven car say a classic car or motor home etc, then putting say 250ml per per tank is good insurance if you know the car is going to sit idle for some time.

      • I use Sta-bil so that I can store petrol for my generator. Don't know about you, but last thing I'd want to have to do is drive to get fuel when there is a blackout and I need fuel…

        If it was diesel you want to store, then Fuel Doctor is the way to go.

      When I looked into it Sta-bil seemed to get a much better wrap for storage of petrol. So that's what I use.

    I used their eBay shop for $8 postage vs $56 on their site

  • Total newb, but besides the cost factor, doesn't 98 Octane do many of the same things?
    Happy to be schooled.

      High end 98s and some 95s have detergents added, yes. This product is for fuels without added detergents. So vehicles that are not high enough compression to use high octane fuels can benefit.

      • thank you! And how do you know what vehicles have high enough compression?
        I'll start researching what 98s have the detergents as well, cheers.

        • Use whatever octane rating’s recommended for your particular vehicle.

          Cars designed to use 98 for example have higher compression engines.

          BP Ultimate, Caltex Vortex and Shell V-Power all have detergent additives.

    Fuel Doctor is more than just a stabiliser or detergent…
