In the DS manual, the lubrication section tells you to use the brp synthetic oil, but in the front of the manual it tells you to use the brp mineral base oil. I was just curious as to how much of a difference it would make. Would the mineral oil be bad for the clutch plates?

 

Any good quality synthetic is fine, as long as it is wet clutch safe. Personally, I believe synthetic is advantageous enough to justify the extra cost.

 

you can use any synthetic oil that is safe for wet clutches, a motorcycle or atv oil. if your in doubt it will say JAS MO rated on it. Synthetic is superior, it even lasts longer than conventional. 80 hour recomended oil changes with synthetic, vs 50 hours with conventional. That fact alone justifys spending a little more for the synthetic

 

Synthetic oil is great just make sure your motor is broken in first before you switch to Synthetic. Mineral based oils are better for your bike when you are seating your rings and breaking in your motor the Synthetic works to good and hinders the break in process. On my Busa build I had my motor completely gone thrue and my builder told me not to switch to Synthetic until I had at least 5000 miles on my motor. that will take me about 10 years LOL.

You can run mineral oil just fine. I run $3.49 Valveline motorcycle oil with wet clutch protection and it works awesome, never one issue. But obviously Synthetic oil is better all around and that's why you will spend quite a bit more money on it.
