So here's the scoop. Usually I do all my own work on my Rex but life has changed my time of availablity. So I took my car to dare I say it(jiffy lube). Ohh that hurt. I figured how bad could they F up an oil change. So let me tell u how they did just that. They put Quaker state 4x4 oil in my Rex I know that it is an AWD car but I believe that it needs more along the lines of a high mileage synthetic 145xxx is what I have put on her. Just curious if anyone has an idea of what possible damage I could incour until I flush my engine of this garbage. Please let me know what u think. Thanks.
