Engine Flush?
I have truck listed at bottom. I currently have about 3700 miles on her. My plan is to put in Amsoil 5W-20 at 10,000 miles. My question is should I use their engine flush? If so why, and if not why.
I am looking for real world and technical reasons. I plan on having this truck "forever"...or at least 200-300k miles. I want some good info, opinions and experience.
Thanks.

I've never used the Amsoil flush but I've used whatever flush my local auto parts store had at the time. I've used an eng. flush in all my vehicles for many yrs----'86 Saab 9000 Turbo(rode hard and put away wet many times), runnin' 14lbs. boost--made it to 290,000 miles(daily driver and track car) when the eng. mounts broke-----'91 Camaro Z281LE(daily driver and track car) was at 155,000 miles when I sold it----'97 F150 4.6-still have it with 100,000 miles on it,----and my 01L--haven't used a flush yet--it's still clean inside. NO internal problems with any of these vehicles--of course--used a syn. oil in all of them too!

Recommended but not required
AMSoil recommends that you flush the oil system before going with AMSoil AND the extended drain interval. The older the engine, the stronger the recommendation.
My opinion, FWIW, is that if you will not be going with a 25K drain interval (assuming a filter change at 12,500 with 1 QT add, and using their filters) and given the low mileage on the truck, you do not need to flush. I also don't believe it will hurt anything althought here are others that disagree and I cannot honestly say there isn't anything to their arguments.
Hope that helps. Again, FWIW, I use the extended drain oil in my truck but change the oil & filter every 10,000 miles. Why? Two reasons: 1. it is cheap engine insurance given that I have a really good oil, a really good filter, and relatively frequent changes and 2. I can remember 10,000 mile intervals easily (I'm serious).
One of these days I think I will get the dual remote bypass filter setup and go with either the extended interval or even the oil testing (change only if needed ever) process. Got to figure out where to easily mount the dual remote setup.
