In order for the fuel to ignite at the proper time during the combustion cycle, you have to use at least the recommended minimum octane level. In the US this, is usually 87, but there are some higher end performance cars that require higher. Check your owner’s manual if you are unsure what octane rating your car uses. If you discover that you have been using the wrong fuel, you can add an octane booster to your tank. It doesn’t matter much which brand you choose as they are designed to simply increase the octane level of your fuel, allowing you to use the gas in your tank. Adding the booster is quite simple ― you just pour it into your gas tank. Using an octane booster to get through your last tank of low octane fuel is fine, but from now, on you want to buy the right kind of fuel. You should also keep in mind that whatever low octane fuel is left in your tank when you fill up will mix with your new fuel, so if knocking continues, go ahead and use the octane booster for another fill-up or two until most of the low octane fuel is gone. It is also thought that using a "top-tier" gasoline such as Shell or Chevron will decrease engine deposits that can cause knocking.

Sketch a picture that you want to finish by inking. While you’re first learning how to ink, it will be better to start with simpler drawings with clean pencil line work and fewer details. Cartoon characters, minimalistic images and simple shapes will work best, since they’ll allow you to focus on clean inking without worrying about the lines running together. Your sketch doesn’t have to be perfect. Just try to get the major lines, focus and proportions right. A lot will change by the time you begin inking. Once your drawing has been sketched out, look for places where you can make corrections or erasures to get the pencil lines as smooth as possible. This will make inking over them easier and result in a neater, more distinct final drawing. Don’t worry about incorporating too much detail during the sketching phase. You’ll be better served if you wait until after you’ve inked the major lines to start adding extra touches.  The pencil lines of your sketch should be precise and clearly defined. Try not to let them run together too much, as this can make inking tricky. Erase pencil mistakes completely so they don’t become a distraction. Inking requires a lot of patience, so you want to make sure you're focused and using the right technique. Sit up straight and position yourself squarely over the paper. If the drawing you're inking is resting on a drafting table or another flat surface, try looking down over the paper so that you have an unobstructed frontal perspective. It's okay if you prefer to work at an angle as long as you can clearly see each detail and move your drawing hand freely.  The more upright you sit, the better. Otherwise, your back may start hurting during lengthy inking sessions. Your work area should be well lit to promote visibility. Grasp the pen firmly in your dominant hand near the tip. Keep the tip of the pen at an angle to the paper, not straight up and down. Hold your hand steady and let your arm guide you over the lines, rather than trying to use the movement of your wrist alone. Relax your drawing hand and arm; too much tension can leave your finished drawing looking rigid and lifeless.  Gripping the pen near the tip, close to the paper itself, will keep it more stable than holding it higher up near the middle. You'll make fewer mistakes, and what small mistakes you do make will be less pronounced. Maintaining a sharp angle between the pen and paper helps pull ink out of the pen more efficiently, resulting in smooth, fluid line work. Go over the lines of your sketch, beginning with one side of the drawing and radiating outward from there. Most artists achieve the best results by inking in the direction of their dominant hand (if you're right-handed, starting on the left side of the page and inking to the right, and the opposite for left-handed artists). This will prevent you from running the edge of your hand over fresh lines. After you’ve inked the major lines, move outward and fill in smaller details and those in the background. This will ensure that the most important elements in the drawing are properly emphasized.  Don’t just trace over the lines you’ve already drawn—imagine that you’re drawing them a second time, this time with the boldness of ink. When you come to a section of the drawing that's difficult to ink, turn the paper and continue in the same orientation, rather than contorting your hand or trying to ink in an uncomfortable direction. Keep the final image in mind when inking your drawing. If you’re just following the same lines you sketched, the objects will look forced and crude. With your first pass at inking complete, look for places where you line work can be touched up. Go over key lines a second and even third time to thicken and smooth them out. Try adding realistic perspective by leaving the lines thin where they face an imagined light source, and thickening them where they’re further away. Tweak your inked lines until you’re satisfied with how they look.  Use a thin nib (the interchangeable tip of a dip pen) and light ink for the initial outline and thicken lines later as you go. Give the ink a few minutes to dry before you start adding detail or going over lines a second time.

While you're waiting for the grill to warm up, lay your bacon strips over the grate in a roasting pan. This pan should consist of a metal grate that fits into a lower "grease catcher" with no holes in it. This allows the bacon to safely cook from the heat of the grill without dripping grease onto the bottom of the grill or burners. As an added bonus, roasting pans make for easy cleanup — just pour the grease out of the lower pan, wash the pan and the grate, and you're done! Add your roasting pan full of bacon to the grill and shut the lid. This keeps the heat from the burners inside the grill, cooking the bacon from both above and below in a fashion similar to baking it. To keep your cooking time low, keep the lid shut during cooking except for when you check on the bacon's progress. Don't forget to turn doing the cooking process — though it's not as essential here because the heat is coming from all sides, rather than just from below, it's still necessary for even cooking. You'll want to turn at least as it cooks — more is fine, but may lengthen the cooking time by allowing the grill's heat to escape. Keep a close eye on your bacon as it cooks — if it's cooking too quickly, flip it immediately and reduce the heat. Once the bacon is cooked on both sides to your liking, use a pair of tongs to remove it from the grill to a paper towel-lined plate. At this point, you're more or less done! Shut off your grill and, once it's cool enough to handle, carefully remove your roasting pan.
