i have always used same as goes in car----10w-40. or the new semi sinthetics will do. iv had it from new {1981} and engine perfect. out on it today.
5wt oil. Use Honda oil.
GN4 Honda oil only.
Honda uses Honda brand oil, made by Exxon Mobil.
No, it is not okay to use an oil not recommended by Honda. You use the snowblower in cold temperatures that is why Honda recommends a 5 weight oil. There's no reason whatsoever to use 10W-30 weight oil. Use 5W-30 as Honda recommends and nothing else. I also recommend you use a 100% synthetic oil in any air cooled engine.
No, you can use any major brand of motor oil you want. However you must use Honda transmission fluid, and power steering fluid. I think you have misread your owners manual as it will not tell you to only use Honda Oil. Honda does not even refine oil and Honda oil is a major brand that is packaged for Honda with their name on the can.
If you mean a different weight then you're not very wise. Use the exact weight oil that Honda recommends. If you are referring to the brand of oil, you do not have to use Honda oil. In fact Honda does not even make oil their oil is refined by another company. You can use any major brand oil of your choice, as long as it is the correct weight.
No
The 2006 Honda Accord requires 5w20 oil. The close tolerances of the Honda engine require the use of this oil for initial startup. Do not use any other oil and make sure to use a premium name brand oil. Also install a premium oil filter such as Purolator or Wix. Another thing to remember on a Honda. Use only Honda ATF transmission fluid and use only Honda Power Steering fluid. Do not use a generic, universal, or substitute.
The best transmission oil to use in any Honda vehicle is the Honda brand. This transmission oil is create to supplement Honda's design and is proven to make the components last.
Honda would maintain that is correct but others would say you can use any JASO MA approved oil.
You can use PH3593A which is a Honda oil filter. There are also other sizes you can use that will fit but they are the Honda brand.
Use Honda 10w40. Remember, the gears and clutch use from the same oil.
