well we all know that i jsut bought a suburban and am in the process of fixing it up so i can use it to tow my TT. I drove it back to Mo. for Tx. and it seems to drive fine. when i changed the oil i used mbl 1 15000 mile oil and also put the $12 Mbl 1 filter. It makes a little noise for less than 2 seconds when i start it up but than goes away. It seems to run better with the mbl 1 than when i brought it up from Tx. It just has the start up noise. is this ok. It sounds like lifter noise. but what do i know.
