D. 50w
The 50W is not a multiviscosity.
yes
Just a plain multiviscosity oil will be fine as long as you change it every 3000 miles or 6 months along with the filter. I don't personally believe that the "high milage oils" are any better than the rest. I DO absolutely believe that regular lube, oil, and filter changes make a big difference.

I was a Mercedes mechanic. I had a 1987 240 DL Volvo which I gave away with 315,00 miles on it. I don't like multiviscosity oils. I have a 1998 E320 wagon with 140,000 miles and I use Valvoline 40W. I live in Los Angeles.
That depends. Is a manual push mower with no motor, or a motorized one? Oil is usually rated by viscosity and I would use a single viscosity oil in a mower. Multiviscosity oils have modifiers to keep them fluid under cold conditions (in a car engine) but still thick when hot. In a mower a 30w oil would be ideal. Use the cheapest oil (in the long run): Amsoil synthetic.
Non-essential oils are oils that are not considered essential oils, which are concentrated plant extracts typically used in aromatherapy. Non-essential oils can refer to cooking oils such as olive oil, coconut oil, or vegetable oil that are not part of the essential oils category.
Not necessarily. 4-cycle engines typically use something around SAE 30 motor oil which can sometimes be used in a car, but is much thicker than the multiviscosity oils used in cars. A car (dependant on manufacturer specs) would use something around 5W30 or 10W30 for older vehicles. Check your owner's manual to be sure what you need.
Many people use gasoline engines. Most new engines require only 5W - 30 oil mutiviscosity for comfortable driving. For older engines you can choose 10W-30 or 10W-40. Heavier multiviscosity oils such as 20W-40 are for high rpm, high-load applications mainly but avoid using it in extreme weather.
Carrier oils are neutral (and non-toxic) oils used to dilute and deliver essential oils. Common carrier oils for use with dry or sensitive skin include: almond oil, olive oil, palm oil, & peanut oil. Common carrier oils for normal skin include jojoba oil, sesame oil, and soybean oil. Common carrier oils for oily skin include: grape seed oil, sunflower oil and walnut oil.
10w30 Any good quality multiviscosity motor oil would be fine in your Jeep. The important part about engine oil is to change it and the oil filter on a regular basis, perhaps every 3000 miles.
To create your own essential oil blends, you can mix essential oils with carrier oils such as coconut oil, jojoba oil, or almond oil. Carrier oils help dilute the essential oils and make them safe for skin application.
