In a Brand new engine it is recommended that you get the rings seated before you start using Synthetic oils.
So run your engine for 3,000 miles and then you can switch to a Synthetic.
No, old oil can use synthetic engines
Synthetic oil works better in some engines than does petroleum-based oil. Nylon is synthetic.
Briggs and Stratton oil must be used for Briggs and Stratton engines. They have both synthetic and standard oil. They have oils formulated for 4-cycle and 2- cycle engines.
Yes, but you do so at your own risk. If the manufacture recommends synthetic oil they have a reason for doing so. Turbo engines, or high performance engines benefit from the use of synthetic oil. My advice is to use synthetic if that is what the manufacture recommends.
Yes, almost every oil brand offers a full synthetic.
That's okay.
It is better for engines, more pure and burns cleaner. It's better for care engines.
Yes
After the break in period it is not an issue.
Dont use synthetic oil in 2.4L DOHC engines. !!!!!
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.
Dermatitis? Engine oils are for engines not your skin.
