    recommended fuel additives?

    This is an occasional use car for me. I expect to do 1000-2000 miles per year. Does anyone have any recommendations on fuel additives to counteract the generally poor ethanol mixed fuel currently available? I use marine grade Stabil in my antique alfa romeos which does a great job in preventing varnish deposition and water adsorption. Any pros or cons for use in a z8?

    thanks

    I have no knowledge of these additives or their pros and cons, but I'd love to hear more about your Alfas!

    Ive been advised to use Stabil as well but I havent really done much with it. I'm curious to hear other people's experiences.

    Imo you don't need additives: it is a modern car which only needs special motor oil

    I have been playing with them for 25 years. I currently have a 65 giulia spider veloce ( one of 1000), a 69 duetto boat tail spider, and two 66 bertone step nose coupes, one of which has a 2 l with spica injection

    its not the modes car which needs the additives, its the crappy modern fuel which turns to paint varnish if you let it sit in the tank long enough.

    Please share some shots of the Alfas in the main forum and keep us posted on what u find here about the additives. For what it's worth I think most of us here are occasional drivers, so our car often sit for weeks at a time, and so far we've had no fuel degradation based issues that I know about.

    There's one recommendation that Jurgen made that I do try to follow, and that is to always fill up when I put her away because the fuel remains more stable without air to oxidize it. Sounds logical, so that's been my own personal strategy.

    I think it depends on the car. Lets say you have a Z8 as a driver and a Z8 Alpina as a collector. The Z8 Alpina gets maybe 100-200 miles a year- really just maintenance driving- In that case Id say its better off to keep like 1/8 of a tank full and drive it down and then replace- this way you can replace it more frequently. In the case of the driver- if you have to put it away for a few weeks/ 2 months for the winter then Id say fill it up- then try to drive out all the gas in a short period of time and fill it up again. Thats basically what I do.

    Stabil

    I've used Stabil very successfully for years on everything from my classic cars, to boat (had twin BB Merc's), to my mowers and tractors. Never any problems and the stuff seems to stave off fuel separation (phasing) and aging problems. I also selectively use STP or a water-out product (HEET) if any of my machinery is to sit for any length of time.
    So far, never any problems. Good luck.

    thanks

    thanks for the input. How is the Audi R8 v10, by the way? That was my other choice.

    Audi R8 V10

    The Audi's great. The second one we've owned. (other was a V8 coupe). Very well built, with great fit and finish. Driving is fantastic. Perfect combo of ride, handling, sport, cruising and vroooom! It's very easy to drive locally, yet can blast off on open freeways in an instant. We've made a few long trips and outside of limited storage space it's a comfortable distance runner. Audi service at the 3 dealerships that I've used around the country has always been great.
    Yet, like any car, I'm beginning to consider what may come next, so may sell this one to move on. If the i8 becomes reality, that, or the presumed new NSX, may join the fleet.

    Still so many cars and such little time!

    I loved the Audi I drove, stunning machine from behind the wheel, but overall it just didn't inspire my desire.

    Seems to me the R8 shows what Audi can do when unshackled from its dogmatic adherence to historic platforms.

    I would like to know this as well. Currently, I also use Stabil marine version because it seems to work fine for my boats in winter storage over the years. I don't fill up before storage as I like to have room to add fresh fuel on the next outing.
