alright kid im about done arguing with you but first i want to say supras have lots of electrical problems there not as good as people say, believe me i had one for three years, i think you've been watching the fast and the furious to much. And as for the truck it has no engine oil problems but it does have a freshley rebuilt 454 in it so the only reason a mazda wouldnt race it would be because they were to afraid after hearing the engine.
