Has anyone done a motor flush on their blazer? Im getting up to 180k and it definitely use a good flush. I have put seafoam in the crank case and ran that for a few days but I am liking the idea of those that you run for like 5 minutes and then change your oil right after. Really want a good deep clean on it. any reccomendations on a good flush solution??

 

I Was never a fan of them personally....

 

Why is that?

 

if its been maintained regularly then you shouldnt have to worry about it.

 

I am about the 3rd owner and don't know how it was maintained. Probably not very well.

 

not sure about those but I use some MMO about 500 miles before oil change.

 

the problem with motor flushes is they loosen deposits up
If you loosen it up and it clogs your lifters then you got problems
IMO it better to let sleeping dogs lie

I have used Castrol oil every oil change since B/N in my Honda
I had it in for timing belt ETC and my mechanic asked what brand I used because the inside was so clean inside
I like Castrol and beleive their claim to cleaning up sludge

 

^^ Use to use castrol conventional on my old ford ranger and it worked well.

 

Gotcha, well maybe Ill hold off then

 

If I were going to do it, I would use Auto-Rx Plus. It's action is much, much gentler than the cleaners most are familiar with.
