Why does my 98 expedition make a pinging noise at 25 to 35 mph then goes away


this noise is detonation. It is an uncontrolled untimed ignition from hot spots in the combustion chamber igniting an incorrect air/fuel mixture. IT is harmful if left un repaired as it has the capability of melting holes in pistons.. Run the fault codes or check /change the air/ fuel mixture settings and ignition timing of the engine . Most engines run around 10-12 degrees advanced and any more than that will help cause the problem, as the spark occurs too early and the extra pressure built up by the combustion will combust the rest of the mixture in the cylinder. Fuel quality is important so if you are using a standard grade fuel( 89-91 octane rated) fill with a premium fuel with a higher fuel octane rating . Give a miss to E- fuel mixtures

I accidently put super unleaded gas.on my VW beetle 2002


That is not a problem it is actually recommended that you use premium 93-94 Octane fuel, if you put turbo blue (115) in it that would be a problem but 93-94 octane is the VW recommended fuel type.

My son put regular gasoline in my 98 deville; will this cause the car to run rough and if so what can i do? p.s. i also went out that same day and put ultra 93. have i damaged my car


Your car is and will be fine - the lower octane fuel just predisposes the engine to
pre-ignition pinging (you don't want to make a habit of it, but its no big deal). Plus, by diluting
it with Ultra 93 octane, you raised the overall octane of the fuel in the tank to somewhere
around (87+93) /2 = 90. Happy motoring.

2001 celica gt whats the recomended Oct


For a standard daily driver 87 octane, I would not use gasoline enriched with ethanol because it degrades the fuel badly. If you put your foot into it and its pinging a bit I'd run 89 regularly and 1 out of 4 fill ups use 93 octane.

Ideal gasoline


87 octane is ideal for your accent.

It's a little commuter car. It's designed to save you money.
Anything over 87 is just a waste of money, UNLESS your engine is knocking at 87. Then you should step up to the next highest grade.
89 is a made up octane. It's just a mix of the lowest grade and the highest grade. I used to work at a mobil gas station for a year, and the only grades i knew wer 87 and 93, but 89 was an available option. it's just a way for oil companies to benefit off of ignorance.
91 and 93 is for high performance engines, turbo-induction, superchargers, that sort of stuff.
you should be fine sticking with the 87 though, but move up to "89 octane" or 91/93 if your engine knocks a lot.
hope this helps.

96 toyota 4 runner won't run


try replacing your fuel filter and spark plugs, engine pinging results from a lower octane than recomended by the manufacturer and dirty gas being burned inside the combustion chamber. good luck!

Fuel


the way i do it . if you put regular gas in and if your hear gas ping then go to the next grade it should quit. i dont like my four banger sounding like a diesel so i use 89 oct so it wont have the gas ping. it use to not ping on regular but lately we have been getting really **** gas around here so i watch were buy gas too.
