Use exactly what your owner's manual lists as the recommended oil.
Unless it is an after market or modify engine for higher performance, a specially turbo applications 20w-50 Synthetics is highly recommended due to higher stress levels and higher temperatures.
But if it is just factory performance engine use what factory recommends because that's what engine was design for.
The owners manual recommends 5w30 or 10w30I would not use 20w50.The owners manual recommends 5w30 or 10w30I would not use 20w50.
10W30, 10W40 and in the summer time 20W50 is okay. That engine does not have a roller valve train in it. So these weights of oil will not hurt it. Just be sure to use a a/c delco oil filter every time.
The computer has sensed a malfunction that is either performance or emmissions related. The engine may be running okay, but you need to have the ODBII scanned to see what the trouble code(s) is/are. The beauty of computers and check engine lights is that the system senses problems while they are at an early stage, therefore, you don't have to wait till the engine runs crappy before you realize there is a problem.
5W30 is not only okay, it is recommended.
Follow the recommendations in your Buell owner's manual. Either Forumula Plus, or Sport Trans. Any 20W50 synthetic engine oil is also okay. For more detailed discussion please check out the Buell Forum at www.BadWeatherBikers.com, specifically the "Knowledge Vault" there. They have a lot of information on all sorts of Buell motorcycles and lots of good information concerning transmission lubrication.
It depends on the type of car engine. Petrol (gasoline) is suitable for gasoline engines, while diesel engines require diesel fuel. Using petrol in a diesel engine can cause significant damage, whereas using diesel in a petrol engine may also lead to poor performance or engine failure. Always check your vehicle's specifications to ensure you're using the correct fuel type.

When it is time to change your oil, you should change all of the oil.
An amp will make them preform better but they will do okay without.
Well, it's slightly better than driving it without oil, or with a time bomb strapped to the engine, but no, it's not "okay".
by going out and buying them things. something like a bed pan or racing gloves would be okay.
Air-cooled engines can be okay in hot weather as long as they are properly maintained and have adequate airflow for cooling. It's important to monitor the engine temperature and ensure that it doesn't overheat during hot weather conditions by providing proper ventilation and cooling. Additionally, using high-quality oil can help improve engine performance and efficiency in hot weather.
