Just asking. I run Amsoil and before the season started, I cleaned the valves after sitting all summer and they pulled right out -- hardly anything on them. That was with around 1700 miles on from last season.

I put close to 4000 miles on this season and haven't had them out yet. I haven't noticed any loss in performance or fuel economy, so I assume they shouldn't be too bad. I plan on cleaning them in the next couple weeks.

Just the regular -- Amsoil Injector. As mentioned above, no need to spend the extra $$$ on the Series 2000, IMO.
