I'm asking because I went to change mine after about 100 miles of running on highway and city just really trying to get it cleaning in there. I took off the filter first because I wanted to see how the oil looked, and I was interested in opening it up. When I took it off it was as clean as ever, Oil looked like it was staight out of the bottle into the oil pan. Filter looked good, not heavy and filled with an overbearing amount of dirt as was expecting. So now I'm wondering what are the results you guys have seen at changing time with seafoam? and have you ever had problems with leaving seafoam in?

details of the truck:

I've got 85,000 miles on it, i've had it since 24,000.

annual Fuel filter changes

90% I use shell gasoline.

I run seafoam or Techron Gasoline additive in my gasoline Between every 5,000-10,000 miles.

I live in Florida in a area where it's not much dust and dirt.

I clean my K&N at the beginning of every season. (not talking sports)

My Gas Mileage DID get better with the seafoam as I did drive home (after the 100 miles filter change) 217 miles using 10.8 Gallons of Gas

I've read a lot about not changing the oil after seafoam but only the filter so I put a performance K&N Oil filter for more filter capacity for now atleast. I've got photos I will post of inside the crankcase. Still golden. Thanks alot!

 

Sorry I don't use the stuff....

I don't feel like pouring a combination mixture of naptha+kerosene+paint thinner into my motor.....especially a vct motor....

 

I understand, I'm just wondering if my situation is common

 

My engine is still clean at 127,000 and all it has ever had is Motorcraft 5-20 blend with a MC filter. The oil barely turns amber at 4,000 miles between changes.

 

Agreed.

Same here.

Seafoam is garbage.

 

I've used it to remove the varnish deposits on the oil control rings on a 1966 engine. Started using a half can and now down to a quarter can in the oil. The results were that the oil control rings are now working and the engine no longer smokes.

I did notice that the oil actually stayed cleaner longer when I used the Seafoam. Possibly by thinning the oil the filter works better? Don't know.

 

ughh, SeaFoam isn't garbage, it does what it says it does. It removes deposits and varnish from inside the engine and oil passage ways. It's not a miracle cure all and shouldn't be used all the time, but it works well for what it is intended for. The problem is, people look at SeaFoam and others as some sort of cure-all. They also assume that all of the smoke they see out of the exhaust when injecting it through the TB or manifold is gun from inside their engine, when in reality the majority of it is the SeaFoam itself. That doesn't mean it doesn't work as intended.

 

The ONLY additive I'll use in the oil is AutoRX and the ONLY fuel additive I'll use is Techron.

 

The only thing that removes varnish is from the Keytone family of solvents. Seafoam contains none of the Keytones. Want to remove varnish, use Berrymans B12. Seafoam contains zero cleaners, it's a 20 viscosity pale(light) oil, naptha, and Isopropyl (rubbing) alcohol. If you can find pharmaceutical grade alcohol at 90%, mixed with ATF and a splash of naptha, you just made a far better cleaner than Seafoam ever could be. At least the ATF brings cleaners to the mix.
