The main problem with grease is that it is so messy. As a result, most people don’t take advantage of it. However, if you buy a standard tube of grease, cut it in half, and use an acid brush to apply it sparingly, you’ll eliminate 95% of the mess and gain a valuable tool.

Using your brush and a tube of grease, you can lubricate parts and linkages you’d otherwise leave bare. Door latch mechanisms, seat slides and hinges all work much better with a thin application of grease. If you’re careful and stingy when you apply it, the grease won’t make much of a mess at all—even on a concours-quality car.

But lubrication isn’t all you can do with grease. If you live in a part of the country where things rust, you’ll find ways to use grease to prevent oxidation; plus, it makes a very good anti-seize compound. A swipe of grease on the threads of any bolt or nut will keep it clean and free for years. Paint the inside ends of coolant and vacuum hoses with grease, and they’ll come off much more easily in the future. Grease even works well to keep electrical contacts from corroding.

The biggest secret about grease is its gasket-sealing ability. Water pump and thermostat gaskets coated with grease won’t leak and are reusable many times. Carburetor-to-intake manifold gaskets love grease.

A wonderful trick uses grease on the valve cover gasket. Attach the gasket to the valve cover with silicone, and grease the side that touches the head. It won’t leak, and you can pull off the valve cover many times without wrecking the gasket.

Don’t use too much grease—just a thin coat is needed. After all, it is messy and will collect dirt. If you’re gobbing it on too thick, wipe off the excess with a rag. It will most likely work just as well, with very little mess.

Where shouldn’t you use grease? Stay away from high heat areas, like exhaust manifolds and headers. It won’t usually catch fire, but it sure will stink. Stay away from brake parts and belts. Some suspension bushings don’t like grease, either. (This is usually a problem with the low-grade parts made from recycled rubber.)

There it is: one of the greatest low-buck tools. Duct tape and mechanic’s wire will always have their place during emergencies, but grease is useful all the time.

Choke Cams

None

A little grease on the choke cams makes a big difference and makes the cable pull much more easily. The carb/intake gaskets are greased, too, and will be reusable when the carbs come off.

Bulbs

None

Grease on the base of the light bulb keeps it working for years. This is probably the only trailer in Michigan with working tailights.

Clevis pins

None

Grease up the clevis pins and lengthen their lives significantly--no squeaks, either.

Thermostat Gaskets

None

Paint up the thermostat gasket on both sides, grease the studs and put the housing back on. Grease up the inside edge of the hose, too. They'll all come off easily next time.

Water Pump Gaskets

None

The water pump gasket won't leak if it's greased, and there's no scraping to remove the gasket next time. A thin coat of grease inside the hose lets it slide on and off easily and won't affect its life.

Valve Cover Gaskets

None

Use silicon to glue the gasket to the valve cover, and then put a thin layer of grease on the bottom of the gasket. You'll be able to pull the cover many times without ever wrecking or scraping the gasket.

Holding Screws

None

Grease can even be used to hold screws to your screwdriver.
