I put a little seafoam in the gas and was wondering if it would be helpful to put a little in with the oil and run it for a short while then change the oil...The person I go the trike from would just ad oil to it since it had a leak..I fixed the leak but suspect there is some sludge build up from not draining it out like you should...
Anyone put a little seafoam in with the oil right before an oil change?
