Put Gas in the tank.Put Gas in the tank.I have a 1994 Cadillac Fleetwood Brougham, and it died at 70 mph, and it did that three times, weeks apart, before we figured out it was the fuel pump. Thought it was electrical because the pump fuse would blow each time. So finally we changed the fuel, with much cost, and that solved the problem. Now it's been many months without the car shutting down on the hiway at very high speed.
turn key to aux and hit gas 3 times within 5 sec. then start the car. if it dosent work the first try again
The gas cap is under the rear license plate. If you have automatic door locks, make sure your doors are unlocked, or you will have in the trunk what looks like a door lock that slides, slide it to unlock your license plate. Then put the gas cap on the right side of the plate to hold it open and pump your gas. At least that is how it works on my 1984 Cadillac Fleetwood Brougham Coupe, that has power everything. Hope this helps : > )
If you are refering to regular gas, it's not recommended. Some people use it as well as myself due to the fact of gas prices. What I do is add a gas octane boost to compansate for the lower octane fuel.
