better gas= happy cadillacs?


Recommended Posts


Your 2000 Deville is optimized to run on 87, so it should not be a problem. Even on 1993-1999 Northstar engines, some people run 87 with satisfactory results. But in 2000, the fuel octane was really taken out of the equation with some differences in combustion chamber and cylinder head design (and a lower compression ratio).

Intermittent stalling + Any 2000 to 2003 Northstar - Any significant trouble codes = Bad Crank Sensors...

Replace them BOTH and all will be well... Almost as common a problem as leaky trunks!

My dealer says to avoid speedways and marthon stations they have had cars towed in and had to drain the gas out of them. It was a popular thing going on for a while. I like to buy premium from Shell or Bp myself - :)
