My car has a problem with cold weather...can this be 20/50 castrol oil, battery, starter, the oil leak from the oil pan, no split pipe, or what i have no clue? car will start after many tries! but once it starts up it will start again til it morning time....when its cold rainy

Many possibilities:
Weak battery cables (feel for a warm spot after cranking).
Old spark plug wires (spray with armorall to displace moisture).
Worn out spark plugs (pull & check them).
Worn out battery (have it tested).

first off why are you running 20/50 castrol? Do you know what the w. even represents? fix the damn leak and try a real motor oil. I'd recomend a 5w-30 or a synthetic 10w-40.besides that there are quite a few things that could be going wrong with your ignition system. Start at the problem and move backwards.

I find that interesting since it is pretty well known that the cold start system was a flawed design from the begining. I still dont understand what Mazda was thinking when they decided to inject coolent into the engine.

20/50 oil is what alot of turbo guys run, also synthetic is normally NOT recomended in stock cars.
