Re: How Much Lower Unit Oil?
How much play is normal in the prop shaft? (When you turn it left to right in gear). Maybe I should drop the lower unit and check. here
The plug may be magnetized and a bit of fine metals is usually ok.

I usually pick up a couple. It's pricey for the good stuff at the Merc dealer, but that's what I use.
If you have detected coolant in your motor oil, your engine should be taken in for immediate service. [links]
A simple way to detect water in used motor oil is to put a drop of oil from the dipstick on a hot exhaust manifold. If it crackles (sounds like bacon frying) this is an indication of water contamination. Beware that there is some risk that the drop of oil may catch fire. Read more about using the crackle test. more
Open the hood and find the dipstick on the engine - a metal loop or grip sticking out of the end of a metal stalk. If you can’t find it, your owner’s manual should help.
If the oil doesn’t reach inside the markings or holes on the dipstick, you need to add at least one quart of oil. If the dipstick is not showing an oil level, you need to add oil immediately. The amount of make-up oil you would expect to add will vary depending on the age of your car, type of engine, total mileage and driving conditions. The dipstick is your gauge for abnormally high oil consumption. Real concern begins at about one quart for every 1,000 miles (0.95 liters for every 1,600 kilometers). It’s time to plan an overhaul if the problem advances to one quart every 500 miles (800 kilometers).
Free and emulsified water is harmful to the oil and the engine. For short-trip drivers, water condensation may be more acute if your engine has the flexible fuel vehicle (FFV) option and you are burning an alcohol-gasoline fuel blend. It is important to remember that combustion produces water in your engine - more water than the fuel consumed. Most of the water goes out the tailpipe, but if the engine is cool, much of it may condense in the crankcase.
Because of wear, vehicles are more likely to consume engine oil as they age. Burning oil is a common problem, but when it is ignored, it can do major damage to your car’s engine. Common culprits that result in burning oil include worn valve stems, guides and seals, and piston rings, all of which can allow oil to seep into combustion chambers. If engine oil gets in the combustion chamber it will burn, possibly in amounts small enough not to produce telltale blue smoke in the exhaust, but enough to notice when you check the car’s dipstick.
So how much burning oil is “normal,” and when does it become excessive? And what if it’s a relatively new engine, such as one with fewer than 25,000 miles on it?
As a rule, most engines with fewer than 50,000 miles shouldn’t use much more than a quart of oil between oil changes (unless the manufacturer says differently). If an engine requires a quart every, say, 3,000 miles or less, that could be a sign of a leak (which may not be easily visible) or of internal engine problems, such as worn valve guides, piston rings or any of a number of different types of seals. Once an engine gets beyond perhaps 75,000 miles, and certainly past 100,000, increased oil consumption should be expected.
This symptom should never be disregarded because low oil pressure or blockage in the lines can lead to complete engine failure.
If You are always confused as to which oil to oil to use for your BMW car, well I will advise you stick to BMW recommended oil and below are the top 2 BMW recommended oil to get for your car.
The oil level sensor warns the driver that the engine is low on oil inside the crankcase. However, when the sensor is faulty, it may incorrectly activate this information.
Is your BMW engine oil at minimum level? What can you do about it? Well, in this post we are going to look at all about BMW engine oil at minimum level.
