Just got my R25, and from my research most people use 10W40 engine oil. However, the showroom I bought it from said that this was recommended for daily short distance rides. For long distance riding 15W50 was recommended. Is this true? From your experience is 10W40 okay for long distance?

Both oil types are acceptable according to the owners manual.

Lower viscocity is thinner and has better flow hence the recommendation to use for short trips since it will perform better for cold startups and you won't be revving the engine high.

Higher viscocity is generally recommended because you are looking at higher revs and as such, will need a thicker oil to maintain protection overtime.

If in doubt, go for the cheapest higher viscocity synthetic EO, just make sure to warm up the bike for about 1-2 minutes.



This is directly from the manual and should give you a better indication.

Thanks so much for the input sir. Will take riding style into consideration as well🙏🏽
