Sorry for advance if my English is with spelling mistakes
I will be happy to hear opinions and recommendations:
I tuned my 2010 155bhp mito, and standing now on 240bhp with 35 tuorqe.
Before the tuning I used the recommended Selenia star pure energy 5w40.
I'm not sure if I should change the oil to 10w60 of Bardhal xtr 39.67, or the Mobil1 racing 0w50, or maybe the Selenia for abarth 5w50, or just stay with the ordinary Selenia star pure energy 5w40. I want to put the best option. I'm changing oil every 10K. The car drove 65K.
My daily driving is calm, twice a month trips with aggressive driving, and 4 trackdays in a year.
The climate in the summer is about -+30·C, in winter is about -+10·C.
Thank you for yours answers, hope I gave all the necessary information.
