I went with the hot type plug because i figured if i had a hotter plug it would burn more or cleaner? I replaced them awhile ago but the truck has not had too many miles since then either, like maybe 1,000 but i doubt that. Probably more like 600 ish. I thought regardless if it made a difference it was still a plug that is recommended in the factory service manual i have so it should be ok. But it was just something i thought i would try, i did not expect it to solve my engine issues. I know the engine is worn out, but it still has some life in it. If i can get it smogged and drive it once a week(if not more) that would be awesome. Yes the engine does consume oil, but i did not think it was to the point to where it was fatal. and if it is then its rebuild time
