With such a good deal on auto-rx availabe I am considering using it in 2 different vehicles, but I have a few questions:
1st vehicle is a 1999 Chevrolet Cavalier Z24 with the 2.4 Twin Cam engine. I purchased this car a year ago with 68,000 miles, now has 84,000. I am presently using Valvoline Durablend oil and the car uses no oil between changes. Due to the great info on this board I am changing to Pennzoil with my next change. Would it be beneficial to use Auto-Rx in this car?
2nd Vehicle is a 1989 Chevrolet K1500 with a 5.0 V8. This vehicle has 115,000 miles and was purchased new by my parents. I have used nothing but Pennzoil 10W30 with 3,000 to 4,000 mile changes since new. I does have the signature Chevy smoke upon start up, but uses less than a quart of oil between changes. My question is my father drives mainly short trips...would this lower the effectiveness of an Auto-Rx treatment? The rear main seal is also beginning to weep. Thanks to all on this board for taking you time to share your knowledge. Happy New Year!
