Motorcycle & Automobile Q & A Forum

Is one motor oil really better than the others for your vehicle?

In a word, yes. Pure synthetic oils now rule the roost of oil hierarchy. But there are also differences in some other oils – like the additives used. If you do not want to spend the extra money on a true synthetic, or a synthetic blend, then you should use a brand name oil – to be sure of the quality and service.

How can I tell, by checking something, if I need to change my oil?

Highly experienced mechanics can tell by looking at and feeling the oil. This is because they have performed or been present for hundreds or thousands of oil changes. It can be risky business for those without adequate experience. With that said, the oil should feel thick and slick, and not be dark in color. NOTE: it is suggested that you change at the interval prescribed by your vehicle’s Owner’s Manual – and, of course, always use Engine Sentry®.

How do I loosen an over-tight oil plug?

First, you’ll want to be sure not to ’round’ the head, which will make removal quite a bit more difficult. Get a closed end wrench that fits perfectly and put it on the plug. Apply a bit of torque to the wrench and the gently tape the wrench with a ball-peen hammer – very close to the plug. Tap on the wrench very near the plug end so that the shocks from the tapping help break the threads loose. Now you’ll need some leverage. Use a ½” drive ratchet and socket, if you have one. If not, a heavy 3/8″ drive will usually suffice. You’ll also want something to use as a ‘cheater bar’ or ‘breaker bar.’ That would be a piece of pipe, for example, that would fit OVER the end of the ratchet handle to give you dramatically increased leverage. Now try to remove the plug using the ratchet and breaker bar. If this is unsuccessful, you can get someone to tap on the socket with a ball-peen hammer while you apply pressure. If this fails, you should take the vehicle in and allow someone with an impact wrench to remove it – before the head is rounded. NOTE: Be sure you have a new gasket for that plug. The old one will definitely be ruined.

I have a can of brake fluid that I used about two months ago. It still has some in it. I only used it once, and closed it right away. Can I use that to fill my reservoir?

NO! Brake fluid quickly absorbs water from the air and that reduces its efficiency. Brake fluid cans announce this on the cans. It’s best to trash any leftover brake fluid as soon as you’re done with the new container. Always err on the side of caution!

How do I clean my battery terminals?

First, you can pour either some white vinegar or strong baking soda solution over them to flush away the corrosion. Then, when they are clean, take a wire brush and slightly rough them up to enhance contact. This can also be done with a piece of sandpaper – about 80-100 grit is best. NOTE: be sure to clean the cable connectors too, to ensure the best connection possible.

How do I convert from using regular engine oil to using synthetic engine oil in my engine?

There really is nothing special that is required. You should allow the old, fossil-based oil to fully drain from the engine – perhaps allow it to drain overnight. Also, be sure to change the oil filter. It’s a great time to install an Engine Sentry®.
