The Echo CS-620P with a 20" bar is a darn good chainsaw for around $650. My dealer will sell it with 20" or 24" bar. It is a higher performance version of the CS-590. I own both the CS-590 and CS 620P both have been good saws for me.
I've seen grease that looked like that in china made assemblies. I have no idea what it is but it does seem to do the job. If it were my project I would just use Valvoline Multi-Vehicle moly fortified gray grease.
Yes and add to this the reservation sells 87 octane non ethanol gas. I constantly get 2 - 3 MPG (depending on the vehicle) better gas mileage over the10% ethanol gas.
I've never seen MPG change in old oil vs new oil in any of my vehicles. However I do see a drop in MPG in cold weather in all my vehicles. Could this be what you are seeing?
What price range? I have a 21" honda 217 with the hydrostatic it is the way to go in a 21" honda. For larger area I love my Ferris FW15 32" with a 10.3 HP Honda engine but they have gone up a lot since I got mine.
I would be suspicious of a spark plug. What plugs did you use? Do you or anyone you know have a scan tool for cars that does cylinder misfire counts? I would start there.
I'm sure it will be fine for Hybrids. Hybirds are getting more and more popular by the month. So the marketing people got to show they are doing something for their paying job. After they seen the Mobil 0w 20 Hybrid oil. :D. However I would not want to be a test dummy for 20K OCI.
Didn't know that was a thing. But I guess it does not surprise me given some of the people I've worked around in my life. Myself I like to do what I can to help get the right part. Thanks for your help.
Does this jeep have two batteries? If so the auxiliary battery powers certain electrical components even when the engine is off. It almost sounds like a weak auxiliary battery. Just my guess.
