I recently made a purchase of a few bottles of Amsoils Performance Improver. Its supposed to clean all the deposits in your valves and on the injectors. Not that you all didn't know that already . I know their diesel oil and additives work great because i work with a few guys that use them on equipment at work but what about for gasoline engines.

Basically, I know Amsoil is top-o-the-line stuff, but I was curious to hear other opinions on it or if anyone else had tried the performance imporver or is loyal to amsoil motor oil.

Personally, i'm not planning on feeling a difference in the running of my car but i always try to keep my car in the best running condition possible (because i'm keeping it forever), as most of you probably do

 

Additives really aren't necessary.

Though once a year I'll run a can of seafoam through my car.

 

hmm i've thought about using the additives but i havent really heard if they work or not

 

ehh once a year ill run stuff threw the car to clean it up

 

I run some STP (Stop Those Pistons) cleaner through mine every year, sometimes a can of octane boost if I'm going to the drag strip.

 

yeah, i've thought about running seafoam too, but I guess i wasn't sure if this stuff was worth it when i bought it. just some preventative maintnence is what i was thinking.

On the bright side, now i got a few bottles to last another year or two
