I used to work with someone who had a 1998 Olds with the GM 3800 V-6. I used to tell her to stay away from Speedway and BP due to the Ethanol content of the gas. At 72,000 Miles the car died and the mechanic told her she didn't have a fuel injector that was working properly and that all 6 had to be replaced for $160.00 per injector. Has anyone else had this problem ?? We are fortunate enough that we can still buy straight gasoline at some stations. I do not use ethanol gas and I also run MMO on every tank for it's lubrication properties and have never had a problem. Just wonder if any of you have had Fuel injector or Fuel pump problems due to Ethanol Fuel.
