I use Mobil 1 10W30 on my Ferris with a 25 HP. Kawasaki
All the Yamaha PW80's and PW50's are 2 strokes, so they dont have engine oil. You mix 2 stroke engine oil into the petrol using 25:1 mixing ratio as im pretty sure you know this already. But they do have transmission oil. You can use 4 stroke engine oil for this, or alternatively, use proper transmission oil.
the fuel capacity for jeep grand wagoneer in the 80s is between 22 gallons and 25 gallons depending on the engine size
6 quarts.. i use 5 quarts of "castol gtx 20 w 50" and 1 quart of "marvels mystery oil"..if you change the timing chain..with that mix you will see 500,000 miles easy..im a 25 year fleet mechanic btw..jeep on ")
For general power use: oil pan capacity is approx. 27 liters oil filter capacity is 4 to 4.5 liters For construction machinery use: oil pan capacity is approx. 25 liters oil filter capacity is 4 to 4.5 liters
The oil drain plug is located on the bottom of the engine underneath the edger. It takes 20 ounces of SAE30 weight oil. I recommend you use synthetic oil in any air cooled engine. Change the oil every 25 hours. Click the link to download an owners manual.
Ordinary 87 gasoline, the same you put in a car. It depends if it is a four stroke or two stroke engine. If the engine has a separate filler for oil then plain petrol will do. If there is no separate filler the 25 to 1 petrol /oil mix should be OK.
On metric gauge 2.5 to 3 bar, about 40 to 45 psi. At least 15 psi, 25 psi would be better, 40 psi on a good engine.
25%
Should be at least 10 at idle. 25 at idle would be better.
No problem
Oil to petrol mix ratio will vary according to chainsaw make and model. Generally if the chainsaw is pre 2000 it will probably be 25:1 (i.e. 25 parts petrol to 1 part oil) Later model chainsaws can be anything from 25:1, 35:1, 40:1 or 50:1. To be safe, you can use 25:1 in all leaner oiled chainsaws but be aware that they will smoke. Always use a high quality 2 stroke engine oil such as super outboard oil or similar. Better to be slightly oily than not.
