I've made a couple of things to my FD and I've gone to to visit a mazda dealer in Barcelona. Well, the problem is that they've put inside my engine the Dexelia mineral oil, 5W30!!! I know it's a good oil and summer is already gone, but... don't you think it's too much for my FD?
I have a track day in a couple of weeks and I want to be sure that this is a safely oil for my FD. What do you guys think?

 

For the street, its fine. However, on the track I would typically run a heavier oil like a 20w50.
