I had an engine failure recently . The engine is still under warrenty but mazda is doing all they can to have me pay for it. I need to show them a proof of service records which is oil changes. I serviced my car regularly but i never keep thae papers & now im screwed . Does anyone have a receipt specifically from kragen (old kragen , not O'rallies) from 5w20 oil ? Ill pay pall you 10$ just for a scan of one receipt.
