Is there a product you add to the oil before you change it

Question

you add maybe a pint no more then a quart drive around a week. Then you change your oil.Just gets more c**p out.

Answer 1

if you chage your oil like you should you shouldn't have a problem with gunk. But I change my own oil regularly and I have not seen anything like that myself.  

Answer 2

No, just drive the car around for a few minutes to get the oil warm before changing, the more viscus it is the easier it will be to get it all out.

Answer 3

you can add sea foam to it and drive it hard for an hour and then change it will help get carbon and clean in side of engine and when i say drive it hard i mean drive it like you stole it other then that theres nothing that i know of u can put sea foam in ur gas tank to to help clean the injectors or suck it thru a vac line just be shure to hi idle the car or the sea form will choke it out youll problyt also need to clear any codes that acure from this you can disconnect the negative battery cable for 30 sec to 5 mins or get a code reader to clear it it will gitve a mis fire code and an o2 code on most obd 2 cars if u suck sea foam in throught a vac line
