I am a believer in Amsoil, not that I sell it or anything of course!
I got my 1999 5.2 Dakota used four years ago at 72k miles. Replaced
the plenum gasket that was blown out in four places and then ran a
complete cleaning cycle using auto-rx. I then used Mobil one 10w-30w
with 7500 mile intervals for awhile till I decided to start using
Amsoil. At around 120,000 miles I switched over to 10w-30w Amsoil
performing the oil changes only once per year which is ~16,000 miles.
The truck was burning a quart of oil every 1000 miles back when I was
using Mobil 1. Now with Amsoil and with a total of 147,000 miles and
when it had a leaky oil pressure sender, it was down to using a half
quart every 1000 miles. I just recently replaced the oil pressure
sender, I am anxious to see how much the oil usage goes down now.
When the valve covers were off the engine getting the gaskets replaced
at 135,000 miles, that engine was spotless, even my Chrysler/Dodge
mechanic friend was shocked, he said it looked brand new.
And oh yeah a funny story from my friend, he had a mid 90's 2wd 3/4
ton V10 Dodge Ram in there that the owner went 30,000 miles without
changing the oil with cheap Dyno oil in it. That poor V10 was so
sludged up that it wouldn't hardly run anymore and the place they
sourced the new longblock from refused to give the core charge back
because that old engine was so sludged up that it was useless. Ever
since hearing about that, I've wondered if that engine could've been
mostly saved with some Seafoam, Auto-rx or something without having to
open it up or replace it.
