Hey guys! Just picked up a 2026 Si which is my 1st turbo manual car and I'm a bit worried about LSPI, what's a good rule of thumb for avoiding it? For example is it like no more than X% throttle Y RPM? What rule do y'all follow?
Use premium fuel and change your oil at least every 5k miles with oil meeting or exceeding owners manual specs.
Low octane fuel and oil blow-by increase pre-ignition risks.
