Question
I have a 1970 Monte Carlo that has been garaged in Texas since 1982. The gas was left in the tank. Can I used an additive to clean the gas or do I need to remove the tank and the old gas. I have not tried to start the car yet. Any pointers on proper steps to take before trying to turn the engine over?

Answer
Hi Paul:
I answer this question a lot...
Any car that won't be driven for 12 to 18 months, should be
prepared for dry storage. Dry storage is when you drain ALL
fluids from the car and put it up on blocks (e.g. remove the tires#.

This car has been sitting for 28 years! I'm guessing the oil and
transmission fluid look like gel. In any case, the first thing to
do is replace ALL fluids #e.g. oil, transmission, brakes, anti-freeze,
power steering and yes, gas. Dump everything. Also check the plugs
for corrosion. If the car was kept in a dry environment, then the
plugs and other ignition and electric system components should be fine.

Turn her over only for a few seconds the first time you try to start her.
This will check the pistons, lifters and valves to make sure they have not frozen.
After a few try at short cranks, if everything appears to move okay, try to start her.

Expertise

Visit my website at: http://www.classytransportation.com/ I can answer most questions about autos built in the 60's 70's and 80's. Specifically, Lincolns, Rolls Royces and the Excaliburs. Mechanical issues and technical questions are my expertise. I also have a general knowledge of most older automobiles. Keep in mind, I can only provide answers if the questions are very specific and complete. Without details, I can only speculate and that's not good for solving your problem.

Experience

I have owned and maintained Silver Shadows for over 10 years now. I find most mechanics and even Rolls Royce mechanics have very little knowledge about these automobiles. I have researched these cars in quite a bit of detail and can pretty much tell you what is wrong, if you can describe the behavior in detail. I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis. I am the owner of Classy Transportation, LLC a luxury limousine service specializing in antique cars, classic cars, vintage cars and exotic cars.
