Active steering on , active steering off . Clear oil , dirty oil .
Active steering is at driver . Clear or dirty oil is at car power .
( Someone driver here with AS on and with AS off have experience about this at drive here . For example 'apex2691' - 'TRA_APEX_'
Someone driver here with clear oil and then with dirty oil he know the difference about this here )
Final :
Best time lap with AS off and Dirty oil ( 11700km ) 1:59,969 . Best time lap with AS on and Clear oil ( 2118km ) 2:00,50
I do not know how times is 1 position with AS off but when car is better with dirty oil then 1 position is with dirty oil .
