I tried to search this question. There are many!! posts about oil etc but I didnt find any specfic answers about the internal engine side effects. I apoligize if its a " Dead Horse " lol......I have an 09 YZf450. I just ordered a Rekluse clutch to run. The Rekluse people recommend the Rotella T. Any bad effects or opinions/experence etc with running this type of oil with internal engine?
