    Hello. New to the forum thing so sorry in advance. 2006 Prius 148k ish miles. Replaced the main battery 2 times now with a refurbished battery. On the third battery. Just started to get codes saying one of the cells is going bad... the other problem is misfires. Had them about a year ago. Pulled the plugs and the ends were wet on all four. Replaced the coils and plugs as well as the seals for the fuel injectors. Problem stopped. Mpg went back up and then over the year it’s gone back down. More misfires and the oil is now a quart low after oil change 6 months ago. The coolant also has an oily smell to it. Could I try something like blue devil for the head gasket or could this be something other than a head gasket? Any advice?

    Don’t use any type of sealer in your cooling system. All it does is clog up things in the cooling system and make more work than it attempts to help.
    Oil burn is a common occurrence on a gen 2 Prius. Look around this site.
