ok-- first off-- any posts by Amsoil dealers will be ignored. Sorry, just can't expect you to do anything other than represent it as the best lube ever. It's nothing personal. You just can't expect an objective opinion from someone with a dog in the fight.
Same goes for you employees of other oil manufacturers, too- to keep it fair.
My queston is simple. I've got the following vehicles:
1989 Chevy S-10 Blazer 4X4. 4.3L V6, 700R4 AT, NP231C transfer case. approx 20K miles on the engine, 8K on the trans.
1990 Jeep Cherokee 4X4. 4.0 I-6, NP231J. junkyard motor in it, no idea of the mileage, but it holds rock-solid 40PSI pressure at hot idle and cruise.
1994 Jeep Grand Cherokee 4X4. Same drivetrain as the 1990 Cherokee. 170,000 miles. short trips mostly under 3 miles [taking the wife to work.
All vehicles engines are internally clean, as inspected top and bottom. They wil be getting Motorguard bypass filters, and I use Purolator Pure-One filters, or the Mobil1/K&ns if they're on sale. I've been using Castrol GTX except for the Blazer which had a leaking oil line to the remote filter- so it got Advance Auto housebrand oil, and have recently switched over to Castrol Syntec in all vehicles [having fixed all leaks].
I intend to go with an extended OCI, with OA done every 5000 miles, perhaps lengthening that interval according to my experience.
OK-- so now we know the field we're on-- what is so great about Amsoil that I should chose it over Mobil1 or Castrol Syntec? I *do not* buy their line about their $30 filter elements being such wonderful things-- should I dismiss Amsoil's lubes as being dramatically better than the lubes I'm using as well?
BTW- yes, I did search first. Saw a lot of messages indexed that showed up as "not available". PArticular among them the one with the title "interesting response from Amsoil". This makes me leary.
