I’ve used Sea Foam in my fuel injected 1985 Mazda RX7 a few times now, both in the gas tank and Sea Foam Spray into the throttle body. The spray has worked especially well! The first time using it really smoothed out the idle and there’s more mid-range power for sure.
Now I have a can of your new Sea Foam High Mileage. Is it just as safe as standard Sea Foam to use in my Rotary engine? Also, I never thought to pour some in the oil until I read the High Mileage label. Is the product safe to use in the crankcase of a Rotary motor?
