    Is Stihl Ultra HP Oil no good?

    The odds of a cold seize with a air cooled motor are extremely low.

    How long can you keep the throttle wide open without load?

    I've not owned a Ford, but I would say that most people, mechanics included way over tighten sparkplug. You really only need to just start to compress the crush washer and you are good. I use a torque wrench and anti seize with all aluminum head auto engines.

    Echo CS 501P vs Stihl MS 260

    It's not just that they are slower. They are as available, they vibrate more snd they are old tech.

    Echo CS 501P vs Stihl MS 260

    I am not sure this is based on reality other than this website. They just don't have name recognition to the general public.

    Echo CS 501P vs Stihl MS 260

    Because Echo's bread and butter is the trimmer,blower, edger, etc market, which honestly is probably a larger market. Just like Redmax. They are old tech for a reason. They just are not an important part of their sales and they are happy with the niche they have. The problem with this is the...

    If he is still running a 30 year old saw he must not be using it much.

    Is Stihl Ultra HP Oil no good?

    Any company worth a damn easily foots the bill. In the scheme of things it's pretty cheap. And many times they don't because they won't pass. So yes many times they are an inferior product.

    If your running it everyday ethanol is less of an issue.

    Echo CS 501P vs Stihl MS 260

    Been around since at least the 70's. I dont know about picking up speed. In fact I could see them discontinuing their chainsaw line completely like Redmax, a direct competitor of theirs did.

    How long can you keep the throttle wide open without load?

    Not a bad idea, but keep on mind you must hold it wide open long enough for the RPM to stabalise.

    Is Stihl Ultra HP Oil no good?

    Maybe so, but nit has none of that stuff in it. The oxygenated in the form of ethanol is blended at the terminal to 10%. Ether was banned by the epa, nitro..no way..etc.

    Will pulling the starter(slowly) without gas in the tank cause engine scoring?

    What you describe is common. Some time it's just streaks of oil/fuel and sometimes it's just superficial marks on the plating.

    Welding fumes must have cooked your brain.

    Is Stihl Ultra HP Oil no good?

    They dont. For starters the additive treat rates are mostly very low and off the 5 or so refiners add they are mostly corrosion inhibitors and anti oxidents. And this is done to keep refinery equipment from having issues. Some station brands like Chevron will add some additional detergent...

    Spectrum is a subsidiary of P66. Omni is a packaging outfit.

    Stihl 2-stroke oil made by Castrol or Not??

    No, Castrol makes Stihl for Canada and other countries. They have nothing to do with Stihl oil in the US.
