Oil change & BG EPR
#11
update for everyone else. Just finished a 600+ mile trip to Pismo this weekend, car was very happy, this EPR stuff seems to do OK. I may try it on an older car with sludge.

EPR is good stuff, on this engine I use 2 cans(one can per gallon of oil is ideal) I also always waste 5-6 qts of oil following the service to flush out the chemical, letting it run and rinse out the passages/components.
EPR is not really designed so much for cleaning out sludge or flushing stuff out(use BG120 for that, and be sure to have a few extra filters on hand if there's much build up). It's really designed to break up carbon that can be riding on the piston rings, not allowing them to properly seal, restoring some lost performance, or keeping from losing it in the first place. I will usually bump the idle and let it run for a good 45 minutes or so with the chemical in there, with a few throttle sweeps along the way. This stuff is pretty volatile, so you don't really want to leave it in there and drive.
