Problem: Article: Put the vegan margarine in a mixing bowl. You can whip it in a standing mixer or use a hand mixer whatever you have in your kitchen. You want to beat the margarine until it's nice and fluffy, so take your time. This will get you the best texture for your frosting. Once your margarine is nice and fluffy, it's time to add the icing sugar. Don't pour it in all at once, however. Slowly add a bit of sugar and then whip it fully into the margarine. Then, add a bit more. Continue adding just a little at a time until the icing sugar and margarine are thoroughly blended together. Once the icing sugar and margarine are fully combined, add in your vanilla. Mix this in. Then, evaluate the consistency of the buttercream frosting. You may need a couple tablespoons of your non-dairy milk or you may not need much at all. You don't want your finished buttercream frosting to be overly dense, but you don't want it to be runny either! If you want chocolate buttercream frosting, add your cocoa powder now. The amount of cocoa powder depends on how chocolatey you want your frosting, so pour in a portion at a time and do regular taste tests. You can use your frosting right away. If you have leftover frosting, or if you simply aren't ready to use yours, pop it in the refrigerator. Once you decorate your baked goods, you will want to keep those in the refrigerator as well so that the icing keeps how you want it. You can save your frosting for 3-5 days in the refrigerator.
Summary: Whip the margarine. Pour in the icing sugar. Add the vanilla and non-dairy milk. Refrigerate your frosting.

INPUT ARTICLE: Article: Mobil One and other oil manufacturers recommend checking engine oil levels before driving your vehicle, when the oil is still cold. However, some manufacturers will recommend checking the oil after you've warmed up the engine, so check your owner's manual to find the specific recommendations for your vehicle. You want the oil to be in the oil pan, not in the engine as it will be while you're driving. Immediately after driving, the oil level will appear lower, making it easier to overfill the oil. If you want to check the oil and have been driving the vehicle, wait five or ten minutes to let it settle into the oil pan before checking it. In very cold weather, it may be appropriate to drive the car around a bit first to get the oil loosened up and less viscous before checking it. Let the engine run for a few minutes, then let it cool down for five before you check it. Many people disagree about whether or not the oil should be checked hot or cold. Some manufacturers recommend checking engine oil warm, and it's perfectly fine to do so as long as you're looking at the right line. There will appear to be "less" oil on the gauge when the oil is colder, but the oil will thin out as the vehicle runs up to normal operating temperature. Synthetic oil expands more when it is hot than "regular" oil does, so it may be best to check your oil cold if you use synthetic oil. Talk to your mechanic if you aren't sure. To get an accurate reading, you'll also need to make sure the oil isn't sloshed to one side of the pan, which can give you a slightly inaccurate reading. Try to find a relatively flat surface on which to park and check your oil. When you check your oil, it's important that you have a couple of paper towels or some other cloth that you can use to wipe it off and check the consistency of the oil. Paper towels usually work best, because it gives you a nice white backdrop contrast to examine the color. Also a great way to keep your hands clean.

SUMMARY: Refer to your owner's manual. Park the car on a flat even surface. Get some paper towels or an old rag.

Split 1 English muffin in half and spread 1 teaspoon of butter over each half of the muffin. Heat a skillet over medium heat and add the English muffin halves with the butter side down. Toast the muffin halves for 3 to 4 minutes, so they become golden and a little crisp. Remove the toasted muffin halves to a sheet of aluminum foil so the buttered sides are facing up. If you want both sides to become crispy, just flip them over and let them toast another minute. Turn the heat up to medium-high and add the last 1 teaspoon of butter to the skillet. Place 1 slice of Canadian bacon to the skillet and fry it for one or two minutes. Use tongs to flip it over several times, so the edges crisp up. Place the Canadian bacon on top of one of the toasted English muffin halves. Watch the Canadian bacon carefully as it cooks, since it could quickly burn. Set a large metal egg ring, small clean can, or large metal biscuit cutter into the skillet and spray it with cooking spray. Crack one egg into the circular container and sprinkle a little salt and pepper over it. Cook the egg for about 3 minutes, so the egg sets. For a simple egg ring, just wash out a small tuna can that's empty. You can just unmold the cooked egg by turning the can over. Use a spatula to lift the cooked egg onto the Canadian bacon that's on your English muffin. Unwrap a slice of American cheese and lay it on top of the egg. Quickly put the other English muffin half on top of the cheese and wrap the aluminum foil over the sandwich. This will seal in the heat and help to melt the cheese. You can eat the sandwich immediately or place the wrapped sandwich into an airtight container. You can freeze the breakfast sandwich or store it in the refrigerator for up to a day.
