That's okay.
Dermatitis? Engine oils are for engines not your skin.
synthetic to conventional - ok conventional to synthetic - no
Yes, you can. It is even sold as a Synthetic Blend.
Synthetic is 100% synthetic. There are blends sold that are part synthetic & regular oil. Look for a quart that sates FULL or 100% Synthetic. If it says Synthetic Blend then it is not 100% Synthetic.Synthetic is 100% synthetic. There are blends sold that are part synthetic & regular oil. Look for a quart that sates FULL or 100% Synthetic.

AnswerI can and do use synthetic oil in lawn mowers and other small engines. The newer design engines with overhead valves and overhead cams such as the Honda usually call for multi weight 10w-30 oil. In those engines just use the same weight oil as called for in the manual but in a synthetic such as Mobile-one. Engines like the flat-head Brigg's call for single weight 30w oil, in those old engines I use 20W-50 synthetic which is a good compromise.Some say it is a waste of money to use synthetic, however the cost is minimal if you use 1/2 quart of $7 synthetic for a once a year oil change you are paying $3.50 for 1/2 quart. If you use regular non-synthetic oil your cost for 1/2 quart would be about $1.75. So your cost to use synthetic is $1.75 a year. If your lawn mower lasts 12 years with synthetic vs 6 years with regular oil then you have saved yourself $250(new mower cost) over 6 years or $41.66 a year toward the cost of a new mower. Commericial heavy users would probably save alot more money.
It might be... It's highly not recommended to mix regular and synthetic oils.
its the same process as changing synthetic oil, except you use regular oil.
10w-30 either synthetic or regular Castrol for regular or Mobil 1 for synthetic
Synthetic oil or a blend of Synthetic and regular oil is much better for your vehicle than regular oil alone. Synthetic oil is MUCH more expenshive. If you change your regular oil every 3 months or 3,000 miles I will be fine.
Yes but once you do there is no turning back and no mixing regular motor oil ever again with the synthetic oil....only straight synthetic....or use semi synthetic....now that can be mixed with regular motor oil in a pinch.
improper oil change intervals. Use synthetic oil and change the oil every 7,500 miles. Ecotec engines are usually forgiving on this, but if proper preventative maintenance such as regular synthetic oil changes at that interval, the chains themselves tend to stretch.
Yes you can.
