Well the dealership knows what is all going on with my car... They are going to talk to jiffy lube and see what to do from there.. The thing is though, the knocking in the engine part happened about 2 months ago or more.. I did take the car into Mazda at that time to let them know whats happening, they didn't hear the knocking at that time and told me to come back.. So I had an apt. setup already for the past sat.. Just happened to so be around the same time my oil was completly empty.. So this could MAYBE be an issue on Mazda's end also.. They did fix my car before - they broke valves, cylinder block and crankshaft.. so it could be that maybe they didnt fix everything properly before and maybe after a little wear and tear the bearings and cam began to break? who knows...
I also asked Mazda if this is Jiffy lubes fault.. they said at this time they don't know they have to look into it more to find out.. possibly maybe they knows its their fault but going to try to put in on Jiffy Lubes fault? Who knows.. I just hope they can figure it out soon so they can fix my car so I am not still driving around wondering when my engine will go..
