Pao3 Posted June 21, 2016 Posted June 21, 2016 l saw 20w50 and 10w40....not sure which one to use... its virago 535 from 1997...thanks guys
Sacha Posted June 21, 2016 Posted June 21, 2016 I think the weight differences are for temperature differences. Seems like 10w/40 covers a wider range (from 10 below to around 45C IIRC).
