Bro no offence but i have been using Esso gold 10w4o since day one on my X-1 and Spark 135.. Had no porblems but better engine and milage.
Why is 20W50 recomended?
10W40 of course can be use on air cooled bike as well. Yeap no problem but mileage wise cannot tahan too long distance.
I myself personally prefer 20W50 or if don have is the closest 15W50 also can.
As for SparkZ in the Specs sheet is recommended Yamalube 4T (SAE 20W40).
I am riding Honda Wave and now still using 20W50. :-)
Not too sure why 20W50 is recommended cause i got it from a website.
What viscosity do you recommend for motorcycles?
Follow the manufacturer's recommendations regarding viscosity.
Most manufacturers recommend a 10W40 for 4-cycle, liquid-cooled motorcycles.
Air/oil cooled motorcycles typically specify a 20W50. Check your owner's manual for verification
