1st of all welcome to the forum! I believe this gen uses 5w-20 oil. Be sure you change the oil on time as the timing chain is lubed by the engine oil. Check for the valve lash. Be sure when you do it. That the engine is cold. Change all of the fluids. Trans fluid, coolant , brake fluid, power steering fluid, check the drive belt if its still good. Check the spark plug's condition only use NGK or Denso. If you can use NGK. Cabin filter. Congratulations on your purchase!
