Re: Another new member, with a question about non-hybrids
sprucetop, FASing is an advanced technique. Unless you realy know what you are doing you should focus on the basics first.
The answer to your question is, like air in the tires, many people have done it as extreem as that and haven't seen any starters or ignition go. However, batteries are a different story. You might want to get some way to measure the battery voltage as it can only take so many discharges below a certain voltage until it goes bad. So if you drive at night and do a fas with the lights on you might wear out the battery sooner than you normally would.
