Got a old suzuki that's running and working just fine. I got the fuel ratio for the bike which is 20:1 this a two-stroke. What I'm trying to figure out is the oil for the bike. Normally do 10w30 or 10w40 in old honda's but didn't know if this bike ran like some old bike that just use the same fuel for inside the engine. Found some specs here: http://www.rhuss.cncfamily.com/1965_k11.htm

Wanted to confirm before going ahead with this.


The best choice for any two stroke air cooled engine is an oil specifally designed for that application. Two stroke oils are designed to burn cleanly and leave no ash behind which is what you want. Look for API "TC" and also JASO FA and FB ratings.

  • if I'm understanding correctly: en.wikipedia.org/wiki/JASO_M345, they didn't establish until 1994. – fassetar Oct 12 '19 at 23:40
  • That's true but today's two-stroke oils are better than what was available in 1966. The lubricate better and smoke less. – jwh20 Oct 12 '19 at 23:42
