I'm getting ready to do the SeaFoam flush in the oil. I've been told by several people to change the oil about 100 miles after you add it. In doing so, I can't image the plugs would be fouled. They were replaced about 3 months ago. Any thoughts?

 

Super old thread here, but curious where y'all might get Synthetic 80w90 gear oil... The only synthetic I can find is amsoil and it's suuuuper expensive. Non-synthetics are regular-priced. Any wisdom there?

 

Just heavy duty CV grease. A regular grease gun tube of Lucas green or red(sticky) is what I use. One large tube per. What the OP meant was a lot of rover places will sell you a tube-like pack that you can squirt in without a grease gun. It is cheaper to do it with a grease gun.

 

I use a LR oil filter and Napa's label 10-40w oil - pretty good price on the oil but not the filter - I have been changing 2x a season or every cross country trip (apx. 2,500 miles)
