Follow the directions on the can - 1/3 can in the tank, 1/3 in the crankcase just prior to an oil change and 1/3 slurped up through the brake booster hose. May be hard to judge when it's needed. Sea Foam wants you to do it every oil change. I think once a year is 'bout right.
Thanks for the reply. I have never used seafoam before and I just bought my truck so really I didn't have a clue. Never messed with this before so maybe oughta find a buddy in the area and get a hand the first time.
I did it on my 03 and and not much changed. my brother did it on his '99 dakota and it helped it quite a bit....I'd say you don't really need it yet with your truck being so new.
Brilliant statement - So how much dilution is done by five ounces of Sea Foam in 900 ounces of oil?
i dont know where u went to school but for ex. the 4.7 holds 6 quarts of oil which is 192 ounces so 5 ounces into 192 is 38.4% thats a pretty good dilution if u ask me
