drzrobbcanuck Posted October 10, 2005 yes, the octane-raising agents in fuel are highly volatile and will dissipate quickly, reducing the effective octane rating. High temps exacerbate the problem. It can be reduced by storing it in a cool, dark place in steel containers. Share this post Link to post Share on other sites

It can be reduced by storing it in a cool, dark place in steel containers. How quickly does the octane start dropping? Will Stabil help? Share this post Link to post Share on other sites
Hanoi G Posted October 11, 2005 It depends a lot on the quality of gas that you get in your part of the country and whether they use an oxygenated gas during the winter.Oregon (where I live) supposedly has some of the crappiest gas around and is oxygenated in the winter. The funny thing about"winter" gasoline is while they claim it pollutes less, I also get worse fuel mileage in all of my vehicles. So I burn more gas. And pollute more. Anyway, Sta-Bil will not help old gas. Drain the tank and carb, put in fresh gas and hope that your pilot jet isn't plugged up. Sta-Bil will help keep new gas good for longer, but I wouldn't trust it for more than a few months around here. Share this post Link to post Share on other sites
DRZ400SK4 Posted October 11, 2005 Use fuel stabilizer in the first place, and you'll never have to deal with the issue. It costs only pennies. Share this post Link to post Share on other sites
prairiedawg Posted October 11, 2005 Yep, and run like crap too. Pour the stuff in your truck and put fresh gas in the bike. pdawg Share this post Link to post Share on other sites
