Cowhide or a synthetic substitute. Synthetic is preferable for playing in wet conditions as such a ball does not pick up extra water weight. The internal air bladder is like a rubber inner tube.
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.
Not necessarily. The w just means it is a winter oil as in SAE 5w20. It is 5 weight when it is cold and 20 weight when it is at full operating temperature. It can be conventional or synthetic. The can will say Synthetic or Synthetic Blend if it is Synthetic.
If you mean 5w20 synthetic the answer is NO. Pontiac recommends SAE 10w30 weight oil in Synthetic or Conventional. Use exactly that weight.
It they are the same weight oil as in SAE 30 weight oil there is no difference and they are identical. 30 weight oil is 30 weight oil synthetic or conventional.
5W-30 Synthetic or Synthetic blend.
It can be. The 5w20 is the weight of the oil which you can buy conventional or synthetic. If it is synthetic it will say so right on the container. If it does not say synthetic it is conventional oil.
I recommend Mobile One 0w40 in the 454. It has the highest quality certifications on the market and is factory fill in many very exotic engines including the pushrod corvette.
look in your owners manual and see what weight oil they recommend and then get that weight oil in the synthetic oil that you like.
Use full synthetic 10w30 weight.
Any major brand synthetic lube in the correct weight.
