Will be removing my OMP soon and have read how to do it and all the pros and cons but cant find much on ratios. So for those of you that do premix what ratio do you find works the best......

 

I Use half quart per fill up, but I'm probably way off as I just took a wild guess.

 

16 oz per tank 128:1 ratio or half a quart. All three are the same amount.

 

I use:
128:1 for street engines (one bottle per fillup of gasoline.)
75:1 for race engines.

 

I use 100:1 when driving on the street (my car cops a pretty hard time)

and as scathcart does i use 75:1 when im down at the black top racing it.

 

pint size bottles?

i use half a quart per fillup. my fillups come to ~15-16 gallons (fill when the light comes on...the s5 tank is actually 18.5 gallons i think) so i end up with roughly an oz to a gallon, or 128:1.

 

i use about 8 oz to 16 galon fil up which comes ou to be 200:1. form what ive heard this is almost double what the factory amount is.

 

500mL bottles to 65L(65,000mL) S5 tank.
Metric system for the metric car.
(yes, a pint size bottle)
