Nikasil coating has been around in Germany for at least 35 years on high revving 2 stroke engines. Way back then I had a Kreidler Florette 50 cc, 6.25 hp at 8500 rpm, torque not noticeable and I had a seized piston caused by tinkering too much with carbs and exhausts (some thing never change:duh?: ), piston was beyond repair, almost no visible damage to the bore surface, new piston and rings and off she went.FXDRYDR said:...Whew!!! Guess I can quit worrying about whether or not my cylinders are going to go to hell!!! Boy - it's been a good week already - first we learned 2618 alloy isn't going to melt or do something else that's horrible and now this!! Man-oh-man -- what a great start to the New Year!!!
Now that's interesting. I stay away from "no-name" brands - except if I'm in the boonies and there's nothing else. Usually use Sunoco, Mobil, Exxon, Shell... always premium. I'd have thought they produce gasoline to a spec and that's that. Wouldn't have thunk it! Darn good idea to purchase on a card for documentation. Thanks for the info.STB said:Either in 2004 or 2005 around memorial day, a refiner in Houston Texas produced and sold high sulphur gasoline. This gasoline went to most big name oil companies along the Gulf Coast from Texas to Florida. Exxon and Diamond Shamrock were not reported as having bought the fuel. Texaco/Shell, Chevron etc did buy it. The high sulphur gasoline reportedly caused the corrosion of the silver contacts in the fuel tank gauge senders. The oil companies paid for the repairs. I closely watched as best I could on the internet whether any nikasil engines were affected. They may have been, but I never saw any reported as being affected, i.e., Jaguar, BMW etc.. I buy Diamond Shamrock or Exxon since then since I run nikasil. I make sure all my fuel goes on a charge card 'cause if they fry my cylinders I want to know whose fuel did it.
