New Year Error

Well I've already made my once a year error. Had to gas up the 95, and compared prices between 2 stations that are 500' apart. My normal station is 10 cents more a gallon, so I went to the other one. Raining, cold, and windy, so I wasn't paying attention. after 11 gallons, I noticed I hit the mid range button. 17 years, and the car has always had 93. Got home and gave it 4 oz of sea foam. Hope it doesn't get mad at me ha ha. I'm sure it'll be ok

It should be fine, especially since it is cold out, premium is only recommended not required, unless you have a tune with real aggressive timing.

Most of my daily drivers used 87, so by instinct, I've accidentally filled my Mark with the wrong OPEC juice.

But I run non-ethanol 92 most of the time.

Thanks Bill. I did that once, and drove to 6 listed stations, and all had the ethanol sticker on the pump. Most are 10%, but there are some that have 15%, that will only work in some newer cars.
Looked them up, and most have 100-110 racing fuel, with lead. There's a few I have to call about the lead content.

I experimented with regular and mid grade, the hit in mileage with regular over premium is nearly a wash if the difference between the 2 is 20 cents. For whatever reason the difference in price has been 30+ cents for awhile, but still won't do anything but premium.

Premium here is 91 octane, same as Kommifornia. Higher elevations in Colorado get 85 octane regular, that is the only fuel my 00 Grand Marquis and my 79 Zephyr couldn't take, they both refused to rev and stumbled like crazy.

I've had no problems with making up the cost difference of premium fuel using performance tunes with the increase in fuel mileage in my daily driver F150 HD over the past several years.

That being said, it hasn't been that long ago that the price difference between regular and premium fuel was 10 to 15 cents per gallon. Now it is consistently 25 to 30 cents per gallon. Seems that the spread was proportional to the cost per gallon as prices went up but not so much as prices came back down? :confused:

For the low miles I drive this car, you are correct, the difference in price is minimal. I get around 4mpg more with premium than with regular. I think it is 12.7 cents a mile with premium (18 mpg at 2.30 a gallon), versus 15 cents a mile with regular (14 mpg at 2.10 a gallon). Not only does it naturally get less mpg with regular, the car needs driven harder to maintain the same driving style (if it can, and it usually cannot).

I have played around with my version of "hypermiling" for the lead foot, and can easily get another 3 mpg and not lose much fun, and make less enemies on the road.

I don't do much highway driving, but I still get really bad mileage. Compared to my wife, she gets better mileage around town than I do on the interstate, I was able to knock down 19 mpg in my Grand Marquis on a long trip to Disneyland, and I don't baby it, pretty hard on it and staying with traffic.

Too bad about your Mark, but I'll bet there is a market here for good parts from it. It might not be enough to get your Mark III, but It's a start.. :)
