What is the best fuel to use in a Grand Marquis?
Hi, yes your car is designed to run on 87 octane. If your vehicle rattles when the a/c is on, but doesn't when you run higher octane, you are hearing detonation. Detonation is bad and can damage the engine. There is a few things that can cause detonation. Most common is the engine is out of timing, but on your vehicle it should be controlled by the computer. If the vehicle has high mileage, it could have carbon build up inside the motor / cylinders / valves, etc. It also could be caused by a faulty EGR system. In your situation if it is a vehicle with high mileage, you may need to stick to the higher octane.
What fuel type for mercury grand marquis?

Scrap or Sell my 1987 Mercury Grand Marquis?
This car has been really good. It only has 96,600 miles on it. Everything is still original. We were told by a mechanic that the engine is in very good condition and will hold up for a few more years. The body is still in great condition. No rust, dents nothing. I am planning on getting a new car really soon but need to know how much i could get scrapping it. Or maybe if it would be better to sell it.
What are the main causes of high oil pressure?
Oil pressure in a car is measured as the resistance to flow between the oil pump in the oil pan and the bearings in the crankshaft. If it is actually too high, it means you are not getting enough oil through the bearings to keep your engine from self destructing.The higher your rpm, the higher your oil pressure, up to the point where an extra valve detours the excess oil back to the oil pan to recirculate. Typically, at idle you will have 10 to 15 psi, with 30 to 40 psi at driving speeds.The colder your engine, the higher your oil pressure, as the oil is still much thicker than it will be at operating temperatures. Typically, on startup, you will have 40 to 60 psi, which will drop to ranges listed above once the engine heats up.A high oil pressure reading on your gauge means:The oil is too viscous (thick). Most cars today are designed for 0W-20 to 5W-30 viscosity. If you are using 10W-40, 20W-50 or something like that, you will have high oil pressure and high wear.Your filter bypass valve on the filter or in the block is stuck closed, and the oil is too thick or dirty to pass through the filter media, trying to go through the bypass valve.If the high pressure is at high rpm, it may be the secondary bypass valve I mentioned at the beginning.Clogged oil passages to the bearings from sludge.Your thermostat is missing or stuck open, not letting the engine heat up.Your gauge is broken. Check it with a manual gauge.
What is the recommended Gas octane for Grand Marquis 1996?
I just bought Grand marquis 1996 , the guy who bought it told me that he always use 91 octane Gas .. but there's a lamp that always appear saying (Check Engine) anyway i decided to use a higher octane Gas specially that the Gas at my country is soo cheap ... so I did use 95 octane Gas and since that check engin lamp turned off and the car performance is better .... BUT FORGET ALL THAT ... i just wanna ask what is the recommended Gas octane for the car ? in my country we have only 91 and 95 octane .... and is it wrong for the car to use higher octane than the recommended like 95 octane ?! Thanks a lot
Do I really have to put PREMIUM gas in my 2003 LINCOLN LS or can I just use REGULAR?
This question has been asked hundreds of times on this board - but here's your answer: Do what the manufacturer recommends - it doesn't matter what kind of car you drive. If it's designed for premium - use it. To do otherwise would compromise your performance and mileage in the short term and possibility reliability and durability in long term addition - to miked - the octane does not only affect you when you rev the engine high - an engine will also be inclined to ping under any heavy load conditions, such as going up a hill with a full load of passengers. You're right in that the computer will adjust the timing when it detects the pinging, but now your 220 HP V6 (or whatever) is making less power, which means you need to use more throttle to get the same performance you're used to, which means using more fuel, so do you really save money by doing this? You save $4 at the fillup, but your car now has worse performance and gas mileage - not a good trade off by my book. If you don't want to pay for premium fuel, don't buy a car that designed/tuned to use it.
Does using regular gas in flex fuel harm the motors?
>> Does using regular gas in flex fuel harm the motors?No, not at all. The real issues are from doing it the other way around — putting E85 fuel in a car not designed for it. Seals and plastics that come in contact with E85 fuel will be prone to dissolving and weakening due to the ethanol content. But putting 100% gasoline in a flex car is not at all harmful. It is even beneficial because it is more efficient (gasoline has more usable energy per unit than ethanol.)E85 is a scam. People think it is more “green” due to deceptive marketing. The “carbon footprint” left from planting corn, harvesting it, and then processing it into ethanol and transporting it to stations is worse on the environment than using gasoline (up to 33% worse than straight gasoline.)Unless it says on the pump that it is pure gasoline, you are already putting E10 in your car due to the political push to use ethanol. But anything higher than 10% ethanol needs to be used only in cars designed to handle the solvent nature of ethanol. But you are fine to use regular fuel. I have a flex fuel car and have never ran anything other than the standard 10% ethanol you find at every pump these days and I probably will never run E85 in it.
