whats the difference? lube control website just specifies that one is soy based (plus) and other (fp60) is petroleum based.

fp plus $49 per gallon treats 10 gal/1 oz of additive.

fp 60 is $37 per gallon treats 5 gal/1 oz of additive.

I have a dead spot in the power band between 22 and 2600 rpm & mpg is high 20s/low 30s. I would like to try and bring it back to normal. any other ideas

the fp-plus is the newest formulation and contains slightly better upper cylinder lubrication properties. plus is also made from renewable base (makes it more liquid like water) and basically you only need 1/2 as much as before so its better in every way. i had fp60 when it was the only one available, now i use the plus. make sure you get the one for gas engines, not diesel.

they are all removed sorry. i dont think the old codes from 2005 work for fp60 anymore either. still well worth it.
