Premium Gas

[marcus]

as per (Adriaan's) quote.
"he personally i like the premium gas, i've has lots of problems with the regular gas here in ontario. The gas here is mixed with ethanol some times up to 15% except shell premium and i believe pioneer. i was having problems with the gas sensor. Took it to the dealer to find out that the since i was mixing fuel with and without ethanol the fuel turned a white color and had damaged the sensor. i work between montreal and toronto. In Montreal there is no ethanol in the fuel as of yet. Since i had it changed i stop buying regular here in ontario and haven't had the problem since. Also I work for esso and i found out that when you mix ethanol fuel like sunoco with regular fuel with out ethanol turns a white color, and as of yet there no technology to separate the two. But this is my experience and what i found out. Not sure if it is true with what i found, or my car was and isolated incident. Also i did a test with sunoco ultra 94 and shell premium on my last trip to montreal. Between my monteal house and toronto house is 686km with ultra 94 i got 536km and with shell i got 636km same driving style going and return about 120km to 140 km on the 401."
