I agree they should check it out...but I wouldn't "demand" anything.:winksCityDave said:I would return it to the dealer and demand that they check the knock sensors and O2 sensors with the hand held scanner that Ford has. This test must be done under load while driving on the road. The Ford Tech can down load the readings while driving and review them after coming back.
If the dealer says that everything is ok have them write that on your RO (Repair Order) recipt and keep it for future action. If the pinging gets worse then again take it back to the dealer to be checked and the work recorded on a RO. This will be your proof that you had the car looked at if you have a future major engine issue.
The engine is required to run on 87 octane as stated in the owners manual. If the dealer says that you have to run a higher grade that is BULLS##T and the dealer knows it. I run a fleet of over 30 Police Interceptors from model year 2001 to 2005 and not one of them pings and they all use the same 87 octane fuel. The only units that I have that run 91 are the BMW and HD motorcycles.
I am so tired of the dealers blowing off the customers that complain of engine knock.
Not true, totally seperate fuel blends- Mobil is much more superior to Lukoil (Getty). Quality control is also better. (ie: dedicated transporters and independant third party testing)zman99 said:BP is Amoco. Thats all I use now. The silver (89) is working for me. I think Mobil and Lukoil use the same fuel, but am not sure. I was not able to tell the difference in any of the brands. The car (my old 2005) ran great on all of them. It just pings away like there is no tomorrow on the 87 octane level of each and every one of them (in the warmer weather). Perhaps Ford did their testing and tuning in Alaska.
I don't know about other states, but in California there is absolutely no difference in octane, the sole determinant of knock resistance, frome brand to another. All gasoline comes from the same tanks at the distribution center. The only difference is in the detegent packages that are added when the fuel is pumped into the storage tanks at the gas station.HazMatLadder26 said:Not true, totally seperate fuel blends- Mobil is much more superior to Lukoil (Getty).
