A small emplacement excavator typically uses hydraulic oil with a viscosity grade of ISO 46 or ISO 68, depending on the manufacturer's specifications and the operating conditions. It's essential to check the operator's manual for the specific model to ensure the correct oil type and viscosity are used for optimal performance and longevity of the hydraulic system.
30 weight
The operating weight of a Caterpillar 245 is 133485.5 lb. It has a fuel capacity of 157.7 gal and holds 9.5 gal of oil.
10 W 40
When we did weight and balance on the small piston engine aircraft I trained on we always used 9lb per U.S. gallon
Small engines....like lawn mowers, compressors, etc typically take a 30 or 40 weight oil. Also, it used to be recommended to break in a new engine with a single weight motor oil.
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.
Most small engines use 30 weight non-detergent type.
weight of oil is lighter than water
To check the hydraulic oil level in a Komatsu excavator, first ensure the machine is on a level surface and the engine is turned off. Locate the hydraulic oil reservoir and remove the dipstick or filler cap; clean it with a cloth and reinsert it without screwing it back in to check the level. The oil should be between the "Full" and "Low" marks on the dipstick. If the level is low, add the recommended hydraulic oil until it reaches the correct level.
The quick answer is probably not. If you are worried, change it to the proper oil, and save the drained oil for the small engines. Small engine oil is usually non-detergent. Detergents help the oil wash off the engine parts. Small engines are usually only used during part of a year, such as in lawn mowers and wood chippers. There, you would want the oil to leave a film on the parts to help prevent rust while the engines are not in service. The other difference would be the viscosity (how thick the oil is). the small engine oil might be thicker. Small engines usually use a staight-weight oil (like SAE 30) where car engines use multi-weight oils (like 10W30). I used to use straight weight oil (SAE 30) in my car until one extremely cold day when the oil became so thick that it wouldn't suck up the pick-up tube, and the oil light wouldn't turn off. I quickly shut off the engine, changed the oil to 10W30, and never used straight-weight oil again. When I sold that car it was 15 years old and the new owner said the engine still sounded like new. So, the engine was not damaged.
Depends on the year but most use SAE 10w30.
