There is a potential issue using current API / ACEA approved oils in high performance cars, which
is worsened if they have been tuned for more power. Standard road oils are designed for long service intervals and have low emissions which they achieve by including extremely high levels of detergents at the cost of reduced anti-wear chemistry. Your performance modified engine wants the opposite.
Changing road oil sooner will help, but it doesn’t solve the issue of low anti-wear chemistry to begin with. Adding ZDDP additives to a high detergent oil doesn’t work, as the detergent will prevent the extra zinc from doing its job.
