I stored my car over winter, i put it away in November if i remember correctly. Before storing it i filled it all the way to full with 93oct gas. I didn't use stabilizer / sea foam. Will running the car with this gas, ~4 months old be harmful? i will try not to make any boost before filling up with a new tank.

Interested in hearing your thoughts. Thanks

 

good question... You may want to ask this in one of the regional forums where they're more likely to put the cars away for storage during winter.

 

i don't think 4 months is a big problem. Car was stored in the winter months so there should not be much of evaporation happening so gas that is in the tank should not have gotten much thicker than it was when you got it.


Just keep on putting some fresh gas in the tank once you use up some of the old one and continue doing that till you completely replace the old gas

 

No it wont hurt it i store my car every winter i just try to avoid boost for the first tank. It is a good idea to use fuel stabalizer but even when I use that I still stay out of boost for the first tank.
