Using Regular Gas

[lester123]

This past weekend I traveled from the Midwest to Florida. There were some gas shortages in Tenn, NC, SC and GA. I was able to find gas, but at one stop, I couldn't find high test. I was a little over half full, so I just added 5 gal of regular. I didn't notice any difference.

What would have been the consequences if I had to add more regular gas to the tank?

If you don't notice the small performance/mpg difference, then there is no consequence unless you hear pinging. Many forum members run 1st gen MDX's on regular gas all the time.

As you add more regular gas, the MDX front will slowly become more squarish, the grill will also become more pentagonal, the "A" legs will separate to form an "H", the third row will expand to 3 seats, the rear will become more boxy, you will lose the ELS, the warranty will shorten by 12 months, you will lose the HIDs, other SUVs will start passing you without mercy on the interstate and finally, one day you will wake up to see this in your garage:



No biggie. I've had to do that occasionally on my 07 and a lot on my 01.

The consequence would have been that you would have paid less for gas. I used to get a tank of "high test" and then a tank of regular. Quit that three years ago. Now just use regular. No consequence.

I used to have a 2002 and high test was "recommended". With the 2008, it is "required".

if you have the situation you were in with a gas shortage, its ok since it was mixed gas, 10 gallons of 93 and 5 of 87, that should average out close to 91 octane. Thats good enough for the mdx since 91 is the highest stuff available in some states. If you were running purely on 87, there would be a few issues. TO avoid these keep the car reving low to avoid damage.

Doh! I only read the first part of his signature! You're dead right.

That sh*t is funny !!!!

You shouldnt be too concerned. I regularly run a mid grade fuel and sometimes regular fuel with out a drastic difference in performance. The milage does seem to be affected. The engines ecm will compensate for the lower octane in the fuel depending on your driving style. For example if you are passing on the highway and demanding more power from the engine and it begins to knock due to the lower octane fuel, the ecm will retard the timing to stop the knocking. Therefore putting out less HP and burning more fuel to maintain the same speed. The MDX has a high compression engine designed to run at peak performance on 91 octane. If you happen to put a lower octane fuel in the tank you probably won't notice a difference in daily driving performance. If you are rally driving it with regular fuel you probably will notice a difference and possibly cause damage to the engine. Just my 2 cents.

Not a big deal. The consequence is you will get less power and probably lower gas mileage. This is because the engine computer will retard the spark timing when it senses detonation.
