He states that he puts what he can afford, HA, I find this crazy but hey it ain't my car and I'm curious to see what and if there will be any effects on his car. As for me it's castrol syntec 5w-30 everytime without fail because of the turbo![]()
I do know that earlier formulations of synthetic oils allowed for leakage in an engine that has been using regular oil for a long period, but I'm pretty sure that mobil 1 and other manufacturers have corrected this leakage problem. It is a hot debate on some forums. I would give it a try and if you notice leaking, switch back to regular oil.
