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.

Thanks

I think Pennzoil is fine. I've used their straight dino oil for years with no problems. If the oil has an American Petroleum Institute Rating of "SF" it's okay. Main thing is to change oil regularly with a grade that is correct for your climate.
