Will Sea Foam help oil burning in a 04 Yukon? [SOLVED]

Thanks for the question, Mike. If the oil burning is caused by varnish, Sea Foam will help overcome it.

Adding Sea Foam Motor Treatment or High Mileage (what I would use) during every oil interval will progressively help to reliquefy the heavier oil residue that’s plugging up the oil flow. Add 1 oz per quart of oil. Do not exceed one treatment per oil interval.

Here’s a detailed article with more info on oil burning and how to fix it: https://seafoamworks.com/shop-talk/stop-the-smoke-cures-for-burning-oil/

Hope that helps and let us know if you have any other questions!
