Octane Boost
I have a spark knockin
97 4.6 4x4 w/ 189k miles.
Its not the brand of gas
its not the plugs
its not the air filter
I was woundering what ya'll thought about trying some octane boost before trying 89 or 93 octane gasoline?

It has been knockin before i had the fuel filter replaced last year, and after
timing is computer controlled you can't mess with it i believe
it always does it under hard throttle ( 3750 rpms on up)
it sometimes does it cruisin on the interstate at 1800-2100 rpms (60-73 mph) (usual cruisin speed)
Its been a while since ive towed the 17' center console boat(my dad usually towes that) i dont remember how it reacted then
The spark knock is not any different when i towe my jet ski.
