I have an '02 4Runner SR5. I have been putting Pennzoil Truck and SUV synthetic blend in it from the beginning (I'm at 61,000 miles now). The engine idles a little rough now (I've had fuel injection system cleaned and replaced the air filter) and so I thought it might be something with the engine and/or oil. Does anyone have a oil suggestion? I've heard from some that pennzoil is bad.
