Donna, I’ll bet that never happens again!

Anyway, the fuel injector rail should have been flushed out also. The oxygen sensor may or may not get damaged, but I think your fuel pump will be ok.

Once all the diesel fuel has run its course and your engine quits smoking you should be all good.

Remember back in the day when gas was less than $.50 a gallon, and you got your windshield cleaned, oil checked, and gas pumped, without asking, all for free, every time? And you didn’t pay for air? And, you got trading stamps to boot?

6 gas-saving myths

By Peter Valdes-Dapena, CNNMoney.com staff writer

NEW YORK (CNNMoney.com) — With gasoline prices hitting record levels, it seems everyone has a tip on how to save fuel. Much of the advice is well-intentioned, but in the end, much of it won’t lower your gas bill.

Here’s a look at a few misconceptions:

#1. Fill your tank in the morning

You may have heard that it’s best to fill your gas tank in the early morning while the fuel is cold. The theory goes that fluids are more dense at lower temperatures, so a gallon of cold gas actually has more gas molecules than a gallon of warmer gas.

Now is the time to have your car in its best running condition for the best fuel economy possible.

Here are a few tips to keep up on your vehicle:

1. First, check your tire pressure on all 4 tires. On a normal car they should read between 32 and 35 psi when the tire is cold. Be sure all tires have the same pressure.
2. If your car is pulling to the left or right while traveling, have the alignment checked. Those with front wheel drive vehicles should get front and rear aligned to insure straight driving.
