I had an 89 Chevy pickup with the 5.7L that had 275k miles on the original engine, tranny, and rear end when I sold it. The oil was changed using regular Castrol GTX 10w30. If the miles were mostly highway the oil was changed at 5000 miles, and 3000 for city and towing...which was done often since I have a lawn service. The engine used approx 1 qt every 3000 miles since it was new. The engine never smoked, ran perfect, and the engine was never touched.

Hp tv dynoed a 8 rwhp gain from a full change to royal purple . I know this could just be to help sell the product. But do u think hp gain is achievalbe w/ other good oils considering that it does help friction and heat? 8 seems like a lot but when i started thinking about the less friction the more power you get to the ground and also the cooler the more power you make. So could this actually be achievalbe. not just from royal purple but other good oils?
