Hi all. I've got 2017 rmz250. The manual states to use 10w40 and I've been using fully synthetic Putoline Nanotech 10w40 from new. My question is:- Would it be ok to start using Motorex 10w50 fully synthetic?
Motorex don't make a 10w40 synthetic. After a bit of research it seems that the manufacturers specify the oil weight due to the designed clearances in the engine. I'm trying to get away from the Putoline and my local shop stock the Motorex because they're a Husky dealer. Reading back it seems like a daft question, but the guy in the shop seems to think it will be ok? I use the 10w50 Motorex in my ktm350exc-f , so it would be useful to be able to use the same oil for both if possible. Can anyone shed any expert like on the matter. Thanks in advance.

So it might actually be better to use the 10w50 now that temps are warming up and summer is approaching?

Doesnt really matter. 40 and 50 are OK. They cover a broad range of temps as you can see in the service manual.

Yeah its no issue to go to the Motorex 10W-50. The bike isn't picky and the warmer temperatures tighten the variability even further.
